Anterolateral thigh fasciocutaneous island flaps in perineoscrotal reconstruction

This study presents the authors' experience using the anterolateral thigh fasciocutaneous flap for complex perineal and scrotal reconstruction. Anterolateral thigh fasciocutaneous island flaps were performed in seven patients between January and June of 2000 (six male, one female; mean age, 52 years; age range, 9 to 72 years). Four of the seven patients had scrotal or perineal defects after multiple debridements for Fournier's gangrene. Two of these four had exposed testicles. Three flaps were used for recurrent ischial ulcers. A true septocutaneous perforator (type 1) running between the rectus femoris and the vastus lateralis muscles was found in only two patients. In four patients, the cutaneous perforators were found to be intramuscular, originating from the descending branch (type 2). In the other patient, the musculocutaneous perforator originated from the lateral circumflex femoris artery independently (type 3). In these cases, intramuscular dissections were performed to follow each perforator to its main trunk. Mean follow-up was 8 months (range, 5 to 10 months), and all flaps survived. Three patients developed minor wound dehiscence in the posterior aspect of the perineal wound because of fecal contamination and skin maceration. Both wounds healed secondarily. Scrotal reconstruction with the anterolateral thigh flap gave an excellent aesthetic result. The authors conclude that the anterolateral thigh flap is a reliable flap for perineoscrotal reconstruction.     

Our experience with Wisebands: a new skin and soft-tissue stretch device

Complex wounds that involve skin and soft-tissue defects that are unsuitable for primary closure by conventional suturing are common in the field of surgery. Among the many surgical options available to overcome these problems are various mechanical devices that have recently been proposed for delayed primary closure of such wounds. The authors present their experience with a new complex wound closure device, Wisebands, a device uniquely designed for skin and soft-tissue stretching. During the last 2 years, the authors have treated 20 patients with 22 skin and soft-tissue wounds for which primary closure was not feasible. The Wisebands devices were applied to the wounds, stretching the skin and underlying soft tissue, gradually closing the defects until the edges were sufficiently approximated for primary closure. Successful wound closure was achieved in 18 patients (90 percent). The Wisebands devices were removed in two patients (10 percent) because of major wound complications. In two other patients (10 percent), minor wound complications had occurred that did not necessitate removal of the device. At a mean follow-up of 1 year (range, 10 months to 2 years), stable scarring with no functional or significant aesthetic deficit was achieved. The authors conclude that the Wisebands device facilitates closure of complex skin and soft-tissue wounds, with low morbidity and complication rates, and can provide the surgeon with another important tool for closing complex wounds. Nevertheless, appropriate patient selection, intraoperative judgment, and close postoperative care are essential to ensure closure and avoid undue complications.     

Suture materials and other factors associated with tissue reactivity, infection, and wound dehiscence among plastic surgery outpatients

The most common complications in plastic surgery are tissue reactivity, infections, and wound dehiscence. In the literature, there are only a few studies with sample sizes large enough and methods of statistical analysis appropriate for evaluating the role of suture materials in inducing such complications. In the 1000 plastic surgery outpatients in this study, the association of different suture materials, individual patient characteristics, surgeon skill, and wound site and length with postoperative wound complications (i.e., tissue reactivity, infection rate, and wound dehiscence) were investigated. No substantial differences were found between the different suture materials and suturing techniques. A moderate increase in the risk of tissue reactivity for silk and polyglactin 910 and a protective effect of thinner internal sutures were observed. In multivariate analysis, such differences were not statistically significant. Male sex [odds ratio (OR), 1.7; 95 percent confidence interval (CI), 1.06 to 2.72] and older age (OR, 2.34; 95 percent CI, 1.36 to 4.05) were found to be the most important risk factors for tissue reactivity and infection rate (male sex: OR, 5.1; 95 percent CI, 1.7 to 15.9; older age: OR, 5.6; 95 percent CI, 1.9 to 16), whereas younger age was associated with an increased risk of dehiscence (OR, 3.06; 95 percent CI, 1.41 to 6.65). Wounds on the lower limbs showed a lower risk of tissue reactivity and wounds on the back a higher risk of dehiscence. Wound length was associated with the risk of tissue reactivity in one-layer sutures (OR, 2.92; 95 percent CI, 1.51 to 5.65). An increased risk of both tissue reactivity (OR, 1.53; 95 percent CI, 1.03 to 2.27) and dehiscence (OR, 2.44; 95 percent CI, 1.1 to 5.43) was observed for operations performed by less-experienced surgeons. Rather than factors related to suture materials and different surgical techniques, and with the exception of surgeon experience, general characteristics of the patients (i.e., sex and age) and of the wounds (i.e., length and site) seemed to be primarily responsible for local wound complications.     

Bicycle spoke injuries in the lower extremity

This study reports the authors' 5-year experience with treating lower extremity injuries in bicycle passengers caused by the spokes. This patient group was selected from 716 lower extremity injuries that received treatment at our outpatient plastic surgery clinic. A total of 26 patients were treated during the study. Patients ranged from 2 to 19 years old, with a mean age of 5.6 years. The authors treated more female passengers (62 percent) than male passengers. The right foot (52 percent) was involved more often than was the left. Most patients were injured in the afternoon, from 2 to 7 PM (62 percent), and between May and October (77 percent). The rear wheel (89 percent) injured the majority of patients. The Achilles tendon was the most common site of injury (63 percent). The typical types of wounds observed included the following: type I, laceration with partial avulsion of skin and subcutaneous tissue (41 percent) and laceration forming a distally based flap (33 percent); type II, abrasions with ecchymoses and friction burn from the shearing effect of the spokes creating a partial- to full-thickness skin defect (26 percent). Of the type I injuries, full-thickness skin lacerations (33 percent) were closed primarily. Partial-thickness skin lacerations, abrasions, ecchymoses, and skin defects (67 percent) were treated conservatively with wound irrigation and dressing. The wound healing time for type I injuries was 29 days; for type II injuries, it was 27 days. These healing times were prolonged compared with healing by first intention. No significant difference was found in healing time when comparing both types of injury. Four patients required hospitalization. No patient required skin grafting. No fractures were noted because these patients were selected from the outpatient plastic surgery clinic and did not include patients from the emergency room. Since the first report of bicycle spoke injuries a half-century ago, prevention has not improved.     

The innervated anterolateral thigh flap: anatomical study and clinical implications

During the past 20 years, the neural anatomy of many flaps has been investigated, although no extensive studies have been reported yet on the anterolateral thigh flap. The goal of this study was to describe the sensory territories of the nerves supplying the anterolateral thigh flap with dissections on fresh cadavers and with local anesthetic injections in living subjects. The sensate anterolateral thigh flap is typically described as innervated by the lateral cutaneous femoral nerve. Two other well-known nerves, the superior perforator nerve and the median perforator nerve, which enter the flap at its medial border, might have a role in anterolateral thigh flap innervation. Twenty-nine anterolateral thigh flaps were elevated in 15 cadavers, and the lateral cutaneous femoral nerve, the superior perforator nerve, and median perforator nerve were dissected. In the injection study, the lateral cutaneous femoral nerve, superior perforator nerve, and median perforator nerve in 16 thighs of eight subjects were sequentially blocked. The resulting sensory deficit from each injection was mapped on the skin and superimposed on the marked anterolateral thigh flap territory. The study shows that the sensate anterolateral thigh flap is basically innervated by all three nerves. The lateral cutaneous femoral nerve was present in 29 of 29 thighs, whereas the superior perforator nerve was present in 25 of 29 and the median perforator nerve in 24 of 29 thighs. Furthermore, in the proximal half of the flap, the lateral cutaneous femoral nerve lies deep, whereas the superior perforator nerve and median perforator nerve lie more superficially. Whereas the lateral cutaneous femoral nerve innervates the entire flap, the superior perforator nerve innervates 25 percent of the flap and the median perforator nerve innervates 60 percent of the flap. Clinically, a small anterolateral thigh flap (7 x 5 cm) can be raised sparing the lateral cutaneous femoral nerve and using only the selective areas innervated by the superior perforator and median perforator nerves. Alternatively, a large anterolateral thigh flap can be raised with this multiple innervation. This can be helpful if one wants to harvest the flap under local anesthesia. Sensate bilobed flaps can be harvested when dual innervated flaps are required.     

Technique and strategy in anterolateral thigh perforator flap surgery,based on an analysis of 15 complete and partial failures in 439 cases

The free anterolateral thigh flap is becoming one of the most preferred options for soft-tissue defect reconstruction. Between June of 1996 and August of 2000, 672 anterolateral thigh flaps were used in 660 patients in Chang Gung Memorial Hospital. A total of 439 flaps were cutaneous or fasciocutaneous flaps based on musculocutaneous perforators. The analysis of the flap failures was done only in this perforator series. In six cases, no suitable skin vessel was found during the dissection of the flaps. The complete success rate was 96.58 percent (424 of 439). Of the 15 failure cases, eight were complete and seven were partial (10 percent to 60 percent of the flap). Thirty-four flaps were reexplored, and 19 (56 percent) were salvaged. In this study, some of the reasons for the flap failure, unique to the anterolateral thigh perforator flap, were identified. They include inadvertent division of perforator at the fascial plane as a result of inadequate knowledge of perforator anatomy, inadvertent injury to the perforator during intramuscular dissection (noted by the surgeon or ignored) as a result of inexperience, and twisting of the pedicle during inset of the flap at the recipient site. Technical pearls in the harvest of the anterolateral thigh perforator flap are as follows: mapping of the skin vessels with a Doppler probe before flap design, meticulous dissection of the perforator under surgical loupe or even lower-magnification microscope, inclusion of a small fascia cuff around the perforator, and intermittent topical use of Xylocaine during the intramuscular dissection of the perforators. During reexploration, one must search for twisting of the pedicle and small bleeders from the branches of the intramuscular perforators.     

Otoplasty: anterior scoring technique and results in 500 cases

Corrective otoplasty is a commonly performed procedure to change the shape of the auricular cartilage. Many techniques use permanent sutures to maintain the cartilage folding, whereas other techniques rely on cartilage incisions (partial thickness or full thickness). At this institution, a cartilage cutting and anterior scoring technique has been used for more than 30 years with pleasing results. The surgical techniques published in the past have been reviewed and compared with the procedure used at this institution to point out the advantages, disadvantages, and differences of these various techniques. Also reviewed were 500 consecutive cases operated on under local or general anesthesia between January of 1993 and December of 1995 to determine the incidence of early and late complications. The patients were contacted by mail to return for a follow-up examination or answer a questionnaire, at least 2 years after the procedure. Early complications were bleeding in 13 cases (2.6 percent) and hematoma in 2 cases (0.4 percent). There were no infections or ear necrosis. A small cutaneous wound was present on the anterior skin in three patients (0.6 percent), and there was one wound dehiscence (0.2 percent). Late complications were keloids in two cases and inclusion cysts in three cases. Residual deformity was noted in 22 cases and asymmetry in 28 cases. Secondary surgery was performed in six cases. The questionnaire was answered by 387 patients (77.4 percent response rate): pain when the ear is touched was present in 22 cases (5.7 percent), hypesthesia in 15 cases (3.9 percent), occasional cutaneous irritation in 38 cases (9.8 percent), asymmetry in 71 cases (18.4 percent), and abnormal ear shape in 17 cases (4.4 percent). Twenty-nine patients (7.5 percent) also noted that the ear was more sensitive to cold or touch. The satisfaction rate was 94.8 percent: very satisfied, 74 percent; satisfied, 20.8 percent; dissatisfied, 4.2 percent; and very dissatisfied, 1 percent. These results were compared with other published series of complications and late results after otoplasty; the complication rates are similar or lower in this study. Therefore, it can be concluded that the cartilage cutting and anterior scoring technique otoplasty is a safe procedure with a high patient-parent-surgeon satisfaction rate.     

Complications after reconstruction by plate and soft-tissue free flap in composite mandibular defects and secondary salvage reconstruction with osteocutaneous flap

Reconstruction of composite defects of the mandible is a challenging problem. Although the use of an osteocutaneous free flap, alone or in combination with another soft-tissue free flap, is generally accepted to be optimal, the bony reconstruction is sometimes undervalued, especially when the cancer is advanced. In such situations, reconstruction is often performed with a reconstruction plate covered with a soft-tissue free flap. Between January of 1997 and July of 2000, 80 patients with composite or extensive composite oromandibular defects underwent treatment with a reconstruction plate and a soft-tissue free flap. All of the patients were male, and the ages of the patients at the time of treatment ranged from 32 to 78 years (mean, 51 years). Tumors were classified as stage IV in 56 patients (70 percent), whereas the remaining 24 patients (30 percent) had recurrent carcinomas. The titanium mandibular reconstruction system manufactured by Stryker (Freiburg, Germany) was used to bridge the mandibular defects. The soft-tissue free flaps used for wound and plate coverage were as follows: anterolateral thigh flap (n = 75), radial forearm flap (n = 3), transverse rectus abdominis myocutaneous flap (n = 1), and tensor fasciae latae flap (n = 1). Five patients with recurrent carcinomas and 10 with stage IV carcinomas (18.75 percent) died 2 to 6 months after the operation and were excluded from the study. The remaining 65 patients were monitored for an average follow-up period of 22 months (range, 6 to 40 months). During that period, one or more complications occurred for 45 patients (69.2 percent). Plate exposure was the most common complication and was observed for 30 patients (46.15 percent). Twenty of the 65 patients (30.8 percent) required secondary salvage reconstruction with a fibula osteoseptocutaneous flap. The decision to perform a secondary salvage procedure was based on the general health of the patient, the extent of local disease, and the severity of the complications. Patients underwent salvage operations after an average of 11.5 months (range, 6 to 26 months). The major reasons for the second operation were as follows: reconstruction plate exposure (n = 12), soft-tissue deficiency and mandibular contour deformation of the lateral face (n = 7), intraoral contracture and lack of a gingivobuccal sulcus (n = 6), trismus (n = 4), and osteoradionecrosis of the mandible (n = 2). The total flap survival rate was 90 percent (18 of 20 free flaps). In two cases, the skin paddles of the fibula osteoseptocutaneous flaps exhibited partial failure and were revised with pedicled pectoralis major and deltopectoral flaps. The reconstruction plate and free soft-tissue flap procedure for the reconstruction of composite defects of the oromandibular region has many late complications, which eventually necessitate reconstruction of the mandible with an osteocutaneous free flap.     

Large-volume circumferential liposuction with tumescent technique: a sure and viable procedure.

During a 4-year period, 152 female and 9 male patients underwent large-volume liposuction, with ages ranging from 19 to 65 years (mean of 36 years), with a weight previous to surgery between 57 and 126 kg (mean of 72 kg). Tumescent liposuction was done simultaneously by two surgeons in several corporal areas according to the necessities of each case. In 28 patients (17 percent), 500 ml of whole blood was required previous to the surgery by self donation. By means of liposuction, volumes between 5 and 22.3 liters (mean of 8.7 liters) were obtained with an average relation of 860 cc of fat for 140 cc of liquid. The reduction of hemoglobin and hematocrit at 1 week after surgery was of 3.8 g and 12 percent, respectively. The weight after surgery during the patient's follow-up varied from 54 to 111 kg, with an average of 66 kg. Major complications were not presented. Minor complications consisted of two superficial cutaneous necroses (1.2 percent) and 18 seromas (11.2 percent), which were drained without leaving sequelae; 24 patients (14.9 percent) presented postsurgical palpable irregularities, visible in only 8 patients (5 percent); 148 patients (92 percent) expressed important satisfaction with the results of the surgery, with the remaining 13 (8 percent) expressing some disagreement due to persistent irregularities. These complications had a direct relationship to some factors of the surgical technique and some characteristics of the patients. The amount of fat liposuctioned, the ideal height-weight relationship of the patient, the diameter of the cannulas used, and the experience acquired during the time were the most important factors that were associated with the complications. Based on these results, we concluded that large-volume circumferential liposuction with tumescent technique is a viable and sure alternative to achieve improvement of the body contour and weight loss.     

Management of complex groin wounds: preferred use of the rectus femoris muscle flap

This study reviews our experience with the rectus femoris muscle flap for complex groin wound reconstruction. Over the past 5 years, the rectus femoris has become our routine method of groin wound reconstruction. The rectus femoris is harvested through a midanterior incision extending over the distal two-thirds of the thigh. The muscle is elevated on its pedicle and transposed into the groin wound defect either directly or through an intervening skin bridge. Hospital and outpatient records were reviewed for all patients undergoing groin wound reconstruction with this technique from 1999 through 2003. Thirty-seven rectus femoris muscle flaps were performed in 33 patients. The mean patient age was 65.3 years (range, 25 to 88 years). Thirty groin wounds (81.1 percent) occurred after infrainguinal revascularization, 23 (76.7 percent) of which contained prosthetic material. Five (21.7 percent) of these wounds had their prosthetic material removed at the time of reconstruction. The remaining seven groin wounds (18.9 percent) occurred after femoral vessel cannulation for either cardiac or transplant surgery. There were no intraoperative mortalities and no anastomotic hemorrhages. There were no flap losses. Thirty-five of the 37 treated wounds healed (94.6 percent), 26 primarily (70.3 percent) and nine (24.3 percent) after delayed healing and contracture. Reoperation was performed in one patient for flap readvancement and in three patients for prosthetic graft removal after initial flap reconstruction. Two patients (6.1 percent) died during their hospitalization with persistent open groin wounds after flap reconstruction. All muscle flap donor incisions healed, with only two (5.4 percent) experiencing minimal delayed healing. There were no donor-site wound infections and no donor sites required reoperation. Thirty-three groin wounds (89.2 percent) demonstrated culture-positive microbial infection, 15 (45.5 percent) of which were polymicrobial. The 30-day mortality rate was 15.2 percent and the 6-month mortality rate increased to 27.2 percent, with multisystem organ failure as the most common cause. The rectus femoris muscle flap is an effective and reliable means of complex groin wound reconstruction. The muscle flap is dependable and the donor site is not problematic, even in the presence of peripheral vascular disease. On the basis of our clinical results, we believe that the rectus femoris muscle flap is the flap of choice for groin wound reconstruction.     

Have we found an ideal soft-tissue flap? An experience with 672 anterolateral thigh flaps

The free anterolateral thigh flap is becoming one of the most preferred options for soft-tissue reconstruction. Between June of 1996 and August of 2000, 672 anterolateral thigh flaps were used in 660 patients at Chang Gung Memorial Hospital. Four hundred eighty-four anterolateral thigh flaps were used for head and neck region recontruction in 475 patients, 58 flaps were used for upper extremity reconstruction in 58 patients, 121 flaps were used for lower extremity reconstruction in 119 patients, and nine flaps were used for trunk reconstruction in nine patients. Of the 672 flaps used in total, a majority (439) were musculocutaneous perforator flaps. Sixty-five were septocutaneous vessel flaps. Of these 504 flaps, 350 were fasciocutaneous and 154 were cutaneous flaps. Of the remaining 168 flaps, 95 were musculocutaneous flaps, 63 were chimeric flaps, and the remaining ten were composite musculocutaneous perforator flaps with the tensor fasciae latae. Total flap failure occurred in 12 patients (1.79 percent of the flaps) and partial failure occurred in 17 patients (2.53 percent of the flaps). Of the 12 flaps that failed completely, five were reconstructed with second anterolateral thigh flaps, four with pedicled flaps, one with a free radial forearm flap, one with skin grafting, and one with primary closure. Of the 17 flaps that failed partially, three were reconstructed with anterolateral thigh flaps, one with a free radial forearm flap, five with pedicled flaps, and eight with primary suture, skin grafting, and conservative methods.In this large series, a consistent anatomy of the main pedicle of the anterolateral thigh flap was observed. In cutaneous and fasciocutaneous flaps, the skin vessels (musculocutaneous perforators or septocutaneous vessels) were found and followed until they reached the main pedicle, regardless of the anatomic position. There were only six cases in this series in which no skin vessels were identified during the harvesting of cutaneous or fasciocutaneous anterolateral thigh flaps. In 87.1 percent of the cutaneous or fasciocutaneous flaps, the skin vessels were found to be musculocutaneous perforators; in 12.9 percent, they were found as septocutaneous vessels. The anterolateral thigh flap is a reliable flap that supplies a large area of skin. This flap can be harvested irrespective of whether the skin vessels are septocutaneous or musculocutaneous. It is a versatile soft-tissue flap in which thickness and volume can be adjusted for the extent of the defect, and it can replace most soft-tissue free flaps in most clinical situations.     

Periumbilical rectus abdominis perforator preservation significantly reduces superficial wound complications in "separation of parts" hernia repairs

Midline ventral hernia repair with bilateral sliding myofascial rectus abdominis flaps, or the "separation of parts" technique, has low hernia recurrence rates. However, this technique, as originally described, creates massively undermined skin and subcutaneous tissue flaps. These undermined skin flaps can suffer marginal skin loss, fat necrosis, and delayed wound healing. The authors propose that preserving the periumbilical rectus abdominis perforators to the abdominal skin flaps will decrease the prevalence of postoperative superficial wound complications. A retrospective review of 66 consecutive, large, midline hernia repairs using a separation of parts technique was undertaken to identify any correlation between the preservation of periumbilical rectus abdominis perforators to the skin flaps and the prevalence of postoperative wound complications. In 25 cases, the standard separation of parts technique was performed with wide undermining of the skin and subcutaneous tissues. In 41 cases, the modified separation of parts technique was performed with maintenance of the periumbilical rectus abdominis perforators to the abdominal skin flaps.Comparison of these two groups revealed no difference in age; sex; body mass index; initial hernia size on physical examination; prevalence of smoking, diabetes, or steroid use; or prevalence of a simultaneous intraabdominal procedure. A statistically significant difference was noted in postoperative wound complications between the two groups (p < 0.05). Of patients who underwent the standard separation of parts technique, five of 25 patients (20 percent) had wound complications as compared with one of 41 patients (2 percent) who underwent the modified separation of parts technique with perforator preservation. The postoperative hernia recurrence (7 percent and 8 percent, respectively) and hematoma (4 percent and 2 percent, respectively) rates were similar in both groups. A trend of increased wound complications was noted when separation of parts was combined with an intraabdominal procedure (18 percent versus 3 percent, p = 0.08). Interestingly, within this group, the modified separation of parts technique with preservation of the periumbilical rectus abdominis perforators demonstrated a trend of fewer wound complications as compared with the standard separation of parts technique (7 percent versus 31 percent, p = 0.15). The authors conclude that preservation of the periumbilical rectus abdominis perforators significantly reduces the prevalence of major postoperative superficial wound complications in separation of parts hernia repairs. Simultaneous intraabdominal procedures with separation of parts hernia repairs seem to increase the prevalence of wound complications. This increased prevalence of wound complications seems to be minimized when the modified separation of parts technique is performed.     

Safety and efficacy of office-based surgery with monitored anesthesia care/sedation in 4778 consecutive plastic surgery procedures

Office-based surgery has several potential benefits over hospital-based surgery, including cost containment, ease of scheduling, and convenience to both patients and surgeons. Scrutiny of office-based surgery by regulators and state-licensing agencies has increased and must be addressed by improved documentation of safety and efficacy. To evaluate the safety and efficacy of the authors' office-based plastic surgery, a review was undertaken of 3615 consecutive patients undergoing 4778 outpatient plastic surgery procedures under monitored anesthesia care/sedation in a single office. The charts of 3615 consecutive patients who had undergone office-based surgery with monitored anesthesia care/sedation between May of 1995 and May of 2000 were reviewed. In all cases, the anesthesia protocol used included sedation with midazolam, propofol, and a narcotic administered by a board-certified registered nurse anesthetist with local anesthesia provided by the surgeon. Charts were reviewed for patient profile, types of procedures, multiple procedures, duration of anesthesia, American Society of Anesthesiologists class, and complications related to anesthesia. Outcomes measured included death, airway compromise, dyspnea, hypotension, venous thrombosis, pulmonary emboli, protracted nausea and vomiting lasting more than 24 hours, and unplanned hospital admissions. Statistical analyses were performed using the Microsoft Excel program and the SAS package. Results were as follows: 92.3 percent of the patients were female and 7.7 percent were male, with a mean age of 42.7 years (range, 3 to 83 years). Patients underwent aesthetic (95.6 percent) and reconstructive (4.4 percent) plastic surgery procedures. Same-session multiple procedures occurred in 24.8 percent of patients. The vast majority of patients were healthy: 84.3 percent of patients were American Society of Anesthesiologists class I, 15.6 percent were class II, and 0.1 percent were class III. The operations required a mean of 111 minutes. There were no deaths, ventilator requirements, deep venous thromboses, or pulmonary emboli. Complications were as follows: 0.05 percent (n = 2) of patients had dyspnea that resolved, 0.2 percent (n = 6) of patients had protracted nausea and vomiting, and 0.05 percent (n = 2) of patients had unplanned hospital admissions (<24 hours). One patient had an emergent intubation. No prolonged adverse effects were noted. There was a 30-day follow-up minimum. Outpatient surgery is an important aspect of plastic surgery. It was shown that office-based surgery with intravenous sedation, performed by board-certified plastic surgeons and nurse anesthetists, is safe. Appropriate accreditation, safe anesthesia protocols, and proper patient selection constitute the basis for safe and efficacious office-based outpatient plastic surgery.     

The lateral osteotomy in rhinoplasty: clinical and radiographic rationale for osteotome selection

A preferred osteotome for endonasal osteotomy would facilitate reliable, complete osteotomies with minimal soft-tissue trauma. In this report, a radiographic evaluation of the bony lateral nasal wall thickness along the track of a high-low-high osteotomy was undertaken to guide the determination of appropriate osteotome size. Bone window axial computed tomographic scans were evaluated in 56 patients with a mean age of 48 years (range, 19 to 86 years). The average thickness along the site of lateral osteotomy was determined to be 2.47 mm (standard deviation, 0.47) in male patients and 2.29 mm (standard deviation, 0.40) in female patients. On the basis of these data, clinical evaluation of prototype 3- and 2.5-mm low-profile guarded osteotomes was undertaken in comparison with a "standard" 4-mm low-profile guarded osteotome to assess both their reliability and the degree of intranasal trauma, as reflected by intranasal mucosal tears. Although 2- and 3-mm unguarded osteotomes are time-tested, they may be reliable only in the hands of the most experienced surgeons. Therefore, a low-profile guard was included in the osteotome design to allow the surgeon to engage the bone securely and minimize the risk of slippage. Forty patients underwent rhinoplasty, for a total of 80 lateral osteotomies; the mean age of the patients was 38 (range, 16 to 75). In all cases, lateral osteotomies were accomplished with one pass. The 4-mm osteotome causes intranasal mucosal tears in 95 percent of osteotomies, the 3-mm osteotome in 34 percent, and the 2.5-mm in 4 percent. Early postoperative edema and ecchymosis were comparable among the groups. One patient, who underwent osteotomies with a 4-mm osteotome, had excessive postoperative narrowing, possibly due to his wearing of eyeglasses earlier than directed. This report suggests that proper selection of osteotome and attention to proper surgical technique results in a reliable, minimally traumatic lateral osteotomy through the endonasal approach. The 2.5-mm osteotome was reliable and the least traumatic to soft tissue of the osteotomes evaluated.     

Anterolateral thigh flap donor-site complications and morbidity

The authors examined donor-site complications and morbidity in 37 patients after reconstruction with free or pedicled anterolateral thigh flaps. Intraoperative assessment included damage to the vastus lateralis muscle and whether the main pedicle of the rectus femoris muscle had been killed. Postoperative assessment of the donor site included wound healing, range of motion, muscle strength, gait, and sensation. Patients were surveyed with a questionnaire about fatigue in their activities of daily life and the appearance of the donor site. All 32 patients who underwent primary skin closure could perform activities of daily life normally, and most (87.5 percent) reported that donor-site appearance was satisfactory. However, the severity of donor-site dysfunction was related to the degree of damage to the vastus lateralis muscle, and most patients (87.5 percent) had some loss of sensation at the anterolateral aspect of the thigh. Because of adhesions between the meshed skin graft and the underlying fascia, range of motion at the hip and knee was limited in significantly more patients who had received split-thickness skin grafts (60 percent) than patients who had undergone primary skin closure (3.1 percent). Therefore, wider flaps or flaps harvested nearer the knee may increase donor-site morbidity. The authors concluded that the incidence of long-term morbidity with the anterolateral thigh flap is low, although it is increased when the flap includes the vastus lateralis muscle or is wider and requires additional skin grafting at the donor site.     

New technique of plication for miniabdominoplasty

The authors present a new method of plication of abdominal fascia performed in 42 patients who underwent surgery for miniabdominoplasty between September of 1998 and February of 2000. The design consisted of a horizontal half-moon on the infraumbilical fascia with high lateral tension, similar to the one that is performed on the skin, achieving an improvement in the muscle-aponeurotic tension of the whole abdomen without requiring a supraumbilical dissection or undermining. All patients (n = 42) had a superficial and a deep conventional liposuction of the abdomen, flanks, and posterior trunk with the wet technique. The rate of minor complications was 59.5 percent. Twenty patients had seromas, three patients had dog-ears and one had cutaneous ischemia (epidermolysis). There were no cases of major complications such as tissue necrosis, infections, deep venous thrombosis, pulmonary emboli, or fat embolus syndrome. Patients received follow-up examination between 6 months and 2 years after surgery (average, 15 months). The results were excellent, and the patients were completely satisfied.     

Management of sternal wounds with bilateral pectoralis major myocutaneous advancement flaps in 114 consecutively treated patients: refinements in technique and outcomes analysis

Because life-threatening sternal wound complications can occur following sternotomy, the optimal management of sternal wound infections remains an important topic. To decrease morbidity following operative treatment of these patients, the authors made a number of refinements in their treatment protocol over the past several years, particularly with regard to the extent of débridement, method of flap apposition, and management of drains. The purpose of this study was to obtain specific outcomes data by reviewing a large series of patients treated by a single surgeon. In this series of 114 consecutive sternal wounds treated by the senior author (Ascherman), patients were managed almost exclusively with débridement and immediate closure with bilateral pectoralis major myocutaneous advancement flaps. There were no intraoperative deaths. The 30-day perioperative mortality rate was 7.9 percent, with only one death directly related to sternal infection. Nineteen patients (16.7 percent) experienced postoperative morbidity, including partial wound dehiscences (5 percent), skin edge necrosis (5 percent), and seromas (3.5 percent). The authors advocate single-stage management of complicated sternal wounds with immediate débridement and bilateral pectoralis major myocutaneous advancement flaps. The procedure is rapid and effective. Refinements in technique have significantly lowered morbidity.     

The sensitivity of the nipple-areola complex: an anatomic study

Although preservation of the sensitivity of the nipple and areola is an important goal in breast surgery, only scant and contradictory information about the course and distribution of the supplying nerves is found in the literature. The existing controversy might be due to the difficulty in dissecting the thin nerves and to frequent anatomic variations that bias the results if only a small number of cadavers are dissected. We dissected 28 female cadavers and found that the nipple and areola were always innervated by the lateral and anterior cutaneous branches of the 3rd, 4th, and 5th intercostal nerves. The most constant innervation pattern was by the 4th lateral cutaneous branch (79 percent) and by the 3rd and 4th anterior cutaneous branches (57 percent). The anterior cutaneous branches took a superficial course within the subcutaneous tissue and terminated at the medial areolar border in all dissected breasts. The lateral cutaneous branches took a deep course within the pectoral fascia and reached the nipple from its posterior surface in 93 percent of the dissected breasts. In 7 percent of the dissected breasts, the lateral cutaneous branches took a superficial course within the subcutaneous fat and reached the nipple from the lateral side. These findings suggest that the nerves innervating the nipple and areola are best protected if resections at the base of the breast and skin incisions at the medial areolar border are avoided.     

Vertical mammaplasty: early complications after 250 personal consecutive cases.

No surgeon likes to face complications. It takes effort to treat them personally and more effort to note, count, analyze, and demonstrate them. The author carefully followed 250 personal consecutive patients (476 breasts) who underwent vertical mammaplasties between 1990 and 1998; studying the complications and their relationship with the types of breasts and patients was very instructive. The main observations from this study follow. The most frequent benign complication was seroma (5 percent of breasts), which usually required one or two aspirations after surgery. Hematomas occurred in six patients (1.2 percent of breasts), who had all had mastopexies. Hematomas required immediate surgical evacuation. The major complication of breast reduction, i.e., areola necrosis, was rare (only two partial necroses occurred), but it left deformities that were difficult to correct. Infection without tissue necrosis was rare (two cases), and healing complications happened in only 5.4 percent of all cases. Healing complications were directly related to the size and fat content of the breasts. None occurred in mastopexy cases. For reductions, delayed skin healing was observed in 5 percent of cases and delayed breast tissue healing in 3 percent of cases. More healing complications occurred after liposuction of the breast, which was performed in the more fatty breasts. Delayed healing of skin and breast tissue was bothersome because healing was slow, but it left only a moderate deformity. In cases of delayed healing, frequent dressings, rinsing the wound with antiseptic solutions, giving antibiotics if needed, and refraining from early surgical intervention are the keys to success. Good personal contact with the patient, especially if healing is slow, is the best way of helping her and avoiding aggressive attitudes. In conclusion, this survey revealed few complications; however, it does show that the risk of delayed and slow healing is greater in larger breasts. In obese patients, a simpler operation may be indicated, such as liposuction with skin reduction alone or a free nipple graft, as long as the patient is not motivated to obtain the best possible result.     

Free flaps in the elderly.

Microsurgical transfer of tissue has become a primary tool of the reconstructive surgeon. The elderly, as a growing segment of our society, are requiring free-tissue transfers in proportion to their numbers. To investigate the potential morbidity of free-tissue transfers in the elderly, we studied consecutive populations of 31 patients above the age of 65 years and 90 patients below the age of 65 years. Complication rates were 65 and 49 percent, respectively. Premorbid medical conditions were present in 87 percent of patients 65 years and older and in 72 percent of those under 65 years. Medically related complications in free-tissue transfers, previously unreported in the literature, were 35 percent in the elderly group and 10 percent in the younger group. Wound-healing complications were seen in equal proportions between groups. The rates of wound and medically related complications observed in the elderly group were nearly double those observed in the younger group; however, after correction for the presence of preexisting medical conditions, no significant differences were seen between the two groups. These observations suggest that age alone is not a variable in risk for free-tissue transfers. Elective microsurgery can be performed in the elderly patient with a high expectation of success.
