Reappraisal of island modifications of lateral calcaneal artery skin flap

Reconstruction of soft-tissue defects of the calcaneal region and the heel is very demanding and necessitates, as a rule, a sensate and thin flap. The ideal characteristics of a sensate and thin layer of flap should be combined with a reliable blood supply and minimal morbidity at the donor site. The authors report an updated review of their experience with the use of island modifications of the lateral calcaneal artery skin flap-the lateral calcaneal island flap, the lateral calcaneal V-Y advancement flap, and the bilobed-shaped lateral calcaneal island advancement flap-for the reconstruction of small and medium-sized tissue defects over the exposed calcaneal tendons and calcaneal bones of 18 patients. All of the procedures were performed under spinal or epidural anesthesia. There were no problems associated with flap viability, but the authors have seen necrosis of undermined skin between the lateral malleolus and calcaneal tendon in two cases and a partial loss of skin graft in one case. In this article, the authors discuss some advantages and disadvantages of the use of a lateral calcaneal island flap and its modifications.     

Prefabricated sensate myocutaneous and osteomyocutaneous free flaps: an experimental model. Preliminary report

Principles of neovascularization have been reported for the successful creation of a variety of muscle and bone free flaps. This study demonstrates a simple and effective technique for construction of prefabricated sensate myocutaneous and osteomyocutaneous free flaps in a rat model. These experiments were carried out in 20 Sprague-Dawley male rats. In half the animals, a sensate myocutaneous flap was constructed by sandwiching the superficial inferior epigastric vessels between a laterally based external abdominal oblique muscle flap and a laterally based skin flap served by an identified cutaneous nerve. A similar preparation included a piece of iliac crest bone. Two to three weeks later, now neovascularized by the sandwiched vessels, the flaps were harvested and transferred as free flaps with high reliability. An increased number of potential donor sites, the versatility of design, and the ability to customize flaps to the specific recipient-site needs are proffered.     

Versatility of the medial plantar flap: our clinical experience

The medial plantar flap presents an ideal tissue reserve, particularly for the reconstruction of the plantar and palmar areas, which require a sensate and unique form of skin. In the past 5 years, the authors performed 16 free flaps, 10 locally pedicled flaps, and five cross-leg flaps on 31 patients for the reconstruction of palmar and plantar defects. All flaps transferred to the palmar area survived, providing good color match and sufficient bulkiness. The overall results were satisfactory in terms of function and sensation, and no complications related to flap survival in the plantar area were observed. All flaps used to cover defects in the heel and ankle region adapted well to their recipient areas, and all lower extremities remained functional. Because the medial plantar flap presents glabrous, sensate skin with proper bulkiness and permits the movement of underlying structures, the authors advocate its use and view this procedure as an excellent alternative in the reconstruction of palmar and plantar weight-bearing areas.     

The versatility of the pudendal thigh fasciocutaneous flap used as an island flap

The pudendal thigh flap is a sensate fasciocutaneous flap based on the terminal branches of the superficial perineal artery, which is a continuation of the internal pudendal artery. Several authors have reported using this axial patterned flap in a bilateral fashion to reconstruct the vagina, mostly in patients with vaginal atresia. The technique is simple, safe, and reliable, and no stents or dilators are required. The reconstructed vagina has a natural angle and is sensate. The donor site in the groin can be closed primarily with an inconspicuous scar.The distinct advantages of this flap widen its indications to several other pathologies. In this article, the authors report on the bilateral use of the flap to reconstruct a vagina in patients with congenital atresia (n = 8) and after oncological resection (n = 5). Furthermore, the versatility of this island flap is also demonstrated by its use in a unilateral fashion in patients with recurrent or complex rectovaginal fistulas (n = 4) and in two patients with a defect of the posterior urethra in a heavily scarred perineum.All 31 pudendal thigh flaps survived completely. Some wound dehiscence was observed in two patients. Two other patients required a minor correction at the introitus of the vagina. The functional outcome was excellent in all patients, despite the presence of some hair growth in the flaps.This article discusses the expanding indications of this versatile flap and the refinements in operative technique.     

Fasciocutaneous island flap based on the medial plantar artery: clinical applications for leg, ankle, and forefoot

Soft-tissue deficits over the plantar forefoot, plantar heel, tendo calcaneus, and lower leg are often impossible to cover with a simple skin graft. The previously developed medial plantar fasciocutaneous island flap has been adapted to cover soft-tissue defects over these areas. This fasciocutaneous flap based on the medial plantar neurovascular bundle is capable of providing sensate and structurally similar local tissue. Application of this fasciocutaneous island flap is demonstrated in 12 clinical cases. Successful soft-tissue cover was achieved on the plantar calcaneus (four patients), tendo calcaneus (four patients), lower leg (two patients), and plantar forefoot (two patients). Follow-up ranged from 6 months to 5 years. All flaps were viable at follow-up. Protective sensation was present in 11 of 12 flaps evaluated at 6 months. In addition, all 11 patients were able to ambulate in normal footwear. The medial plantar island flap seems to be more durable than a skin graft, and the donor site on the non-weight-bearing instep is well tolerated. This study demonstrates that the medial plantar fasciocutaneous island flap should be considered as another valuable tool in reconstructive efforts directed at the plantar forefoot, plantar heel, posterior ankle, and lower leg.     

Reconstruction of soft-tissue defect of the posterior heel with a lateral calcaneal artery island flap

We obtained most favorable results in 11 patients with a lateral calcaneal artery island flap. It is a simple, stable, sensate, and yet safe and versatile flap to repair defects around the ankle and heel. We have also used this flap to cover defects around the medial malleolus without any delay (extended lateral calcaneal artery island flap).     

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.     

A fasciocutaneous flap for vaginal and perineal reconstruction

A skin and fascia flap from the medial thigh is proposed for vaginal and perineal reconstruction. Dissection, vascular injection, and radiographs of 20 fresh cadaver limbs uniformly demonstrated the presence of a communicating suprafascial vascular plexus in the medial thigh. Three to four nonaxial vessels were consistently found to enter the proximal plexus from within 5 cm of the perineum. Preservation of these vessels permitted reliable elevation of a 9 X 20 cm fasciocutaneous flap without using the gracilis muscle as a vascular carrier. Fifteen flaps in 13 patients were used for vaginal replacement and coverage of vulvectomy, groin, and ischial defects. Depending on the magnitude of the defect, simultaneous and independent elevation of the gracilis muscle provided additional vascularized coverage as needed. Our experience indicates that the medial thigh fasciocutaneous flap is a durable, less bulky, and potentially sensate alternative to the gracilis musculocutaneous flap for vaginal and perineal reconstruction.     

Reconstruction of the radiated partial mastectomy defect with autogenous tissues.

As conservative surgery and radiation therapy have become accepted treatments for early-stage breast cancer, increasing attention has focused on the cosmetic results of this technique. When partial mastectomy--a term which encompasses a diversity of excisional techniques--is followed by radiation therapy, breast defects characterized by parenchymal loss, nipple-areola complex distortion, and cutaneous abnormalities can occur. From 1981 to 1990, eight patients sought reconstructive correction of a radiated partial mastectomy deformity. Patients were from 42 to 70 years of age (mean 49 years). All had breast cancer, except for one patient with diffuse and chronic breast abscesses. Six patients were reconstructed with latissimus dorsi flaps and two with rectus flaps. No patient underwent reconstruction sooner than 1 year after completion of radiation therapy; for the entire group, a mean of 2.6 years elapsed from completion of radiation therapy to flap reconstruction of the breast. Mammograms were obtained on all the breast cancer patients before and after the myocutaneous flap procedure. Follow-up extended from 1 to 9 years after reconstruction (mean 3.6 years) and included both physical examination and serial mammographic evaluations. Myocutaneous flap reconstruction with either latissimus or rectus flaps achieved an aesthetic improvement of the partial mastectomy deformity in all eight patients. Complications consisted only of seroma formation in two patients following latissimus flap reconstruction. Mammographic evaluation revealed fibrofatty degeneration of the soft tissues of both types of flaps, a change that occurs as early as 6 months after operation and appears as a radiolucent area. The feasibility of mammography as a screening adjunct for recurrent cancer in this group of patients is demonstrated. Advantages of this technique of autogenous tissue reconstruction are improvement of contour deformities associated with conservative surgery and radiation therapy, preservation of normal, sensate breast skin, enhancement of symmetry with the contralateral breast, and avoidance of a prosthesis.     

A new technique of vaginal reconstruction using neurovascular pudendal-thigh flaps: a preliminary report

The blood supply to the skin of the perineum, medial groin, and upper thigh was studied in fresh female cadavers. The pudendal-thigh flap was designed as a result to reconstruct the vagina. The flaps are raised bilaterally in the groin crease just lateral to the labia majora and then are transposed toward the midline and sutured together to form a skin-lined cul-de-sac which opens at the introitus. The technique has been used successfully in three patients to reconstruct the vagina. The first patient, an adult, was reconstructed after total pelvic exenteration for malignancy, while two children had reconstructions for congenital vaginal anomalies. This technique is superior to currently available methods because it is simple and reliable. No stents or dilators are needed. It is safe technique without complications in our hands. The reconstructed vagina has a natural angle for intercourse and is sensate. The donor scars in the groin are well hidden.     

Long-term follow-up of total penile reconstruction with sensate osteocutaneous free fibula flap in 18 biological male patients

Surgical reconstruction of the penis is challenging because of the many cosmetic and functional (e.g., sexual intercourse and voiding) requirements that must be addressed. Since the free sensate osteocutaneous fibula flap was first described for total penile reconstruction in 1993 it has been widely accepted, with its advantages and minimal shortcomings. In this article, the authors present the longest follow-up of biologically male patients with free fibular phalloplasties. Since 1994, 18 biologically male patients with total penile losses for various reasons were treated with free sensate osteocutaneous fibula flaps. All patients were included in the study. The ages of the patients ranged between 20 and 26 years (mean, 22.2 years). The average follow-up period was 5.4 years (range, 1 to 9 years). Patient satisfaction was evaluated by a questionnaire regarding both quality of orgasm and daily activities. Conventional radiographic imaging, magnetic resonance imaging, and bone mineral densitometry were performed to evaluate the fate of the bony component of the flap. Also, sensibility was evaluated by bulbocavernous reflex and penile somatosensory evoked potentials testing in nine patients. Six patients married, and five of them had six children. Most patients and their partners reported pleasurable sexual intercourse and orgasm. Conventional radiographs of the fibular bone in neophalluses showed robust, calcified bone structure without any evidence of bone resorption or fracture. The magnetic resonance images showed the cortical substance and spongiosum of the bone marrow, which are characteristic signs of bone viability. After intravenous injection of gadolinium, the neophallus bone showed uptake of contrast medium. Viability of neophallus bone was shown even at 9-year follow-up (the longest follow-up in the literature). Dual energy x-ray absorptiometry measurements of the penile bone grafts showed that fibular components in the penis had bone mineral density values that were close to but lower than those of intact fibula in the same subjects. These results were considered as evidence of viability of bone grafts. Neural integrity was found between the nerves of the neophallus and the residual penile bodies by both bulbocavernous reflex and penile somatosensory evoked potentials tests. In conclusion, free sensate fibula flap phalloplasty provides the cosmetic and functional requirements that an ideal penis should have. All results put an end to the discussion that the fibular component of the neophallus could resorb. Constitution of neural integrity is important in terms of pleasurable sexual intercourse. The authors believe the free sensate osteocutaneous fibula flap should be considered as the standard in penile reconstruction.     

Breast reconstruction using the sensate latissimus dorsi musculocutaneous flap

The authors performed immediate breast reconstruction on four patients using a sensate latissimus dorsi musculocutaneous flap accompanied by neurorrhaphy during the past 6 years. In the neurorrhaphy, the lateral cutaneous branch of the dorsal primary divisions of the seventh thoracic nerve, which controls the sensation of the myocutaneous flap, was anastomosed to the lateral cutaneous branch of the fourth intercostal nerve, which controls the sensation of the breast. The subjects consisted of four patients whose postoperative follow-up period was 14 to 29 months, with an average of 19.3 months. The control subjects consisted of 10 cases with a latissimus dorsi musculocutaneous flap whose sensory nerve had not been reconstructed (postoperative follow-up period, 15 to 49 months; average, 26.9 months). The sensory examination included tests of touch, pain, and temperature. The innervated musculocutaneous flap sensation showed gradual recovery at about 6 months after surgery and reached the value of the normal side after about 1 year. In the control subjects, the recovery was gradual after more than 1 year and reached the value of the normal side in only some of the control subjects. On the basis of these findings, the authors consider the present technique to be useful for the recovery of sensation in immediate breast reconstruction.     

Leg length preservation with pedicled fillet of foot flaps after traumatic amputations

Six patients with insufficient soft-tissue coverage after lower limb trauma were treated with pedicled fillet of foot flaps to achieve primary stump closure and to preserve leg length. The flaps used were all based on either the posterior tibial neurovascular pedicle, the anterior tibial neurovascular pedicle, or both. Five flaps survived; one patient required conversion of a through-knee to an above-knee amputation and debridement of the flap because of venous thrombosis of the pedicle. In three of the cases, a functional knee joint was preserved. The patients ranged in age from 21 to 54 years, the mean hospital stay was 55.5 days (range, 28 to 76 days), and the mean follow-up time was 14.5 months. Despite an average of 4.3 procedures from initial admission to first discharge and an average of 2.0 postamputation procedures to achieve primary stump healing, all patients have achieved independent mobility with their prosthesis. The advantages of preserving leg length and, where possible, preserving a functional knee joint compensate for repeated procedures on these patients. When planned well, a pedicled fillet of foot flap therefore achieves the aims of amputation, namely, providing primary healing of a sensate, durable, cylindrical stump that is pain-free and preserves maximal leg length. This is achieved with no donor-site morbidity and with no need for microvascular reconstruction.

Liposuction abdominoplasty: an evolving concept

Liposuction abdominoplasty-liposuction of abdominal subcutaneous tissue deep and superficial to Scarpa's fascia, with excision of excess abdominal skin and, when indicated, plication of the anterior rectus sheath without undermining-is an effective, low-risk approach to minimizing abdominal flap undermining. The technique allows aggressive thinning and "sculpting" of full-thickness abdominal subcutaneous tissue and achieves a natural (not featureless) abdominal contour. It minimizes the creation of "dead space," which often leads to postoperative complications, as well as preserves sensory nerve and blood supply to the abdominal skin. The operation may be performed with the patient under local anesthesia, which probably diminishes the risk for deep vein thrombosis. Moreover, additional procedures can be conducted safely and the postoperative course is short, uneventful, and without restrictions; patients return to normal activity within a week or so. New evaluation criteria for abdominoplasty are discussed in this article, the most important of which is the assessment of intraabdominal fat content and its impact on surgical outcome and the decision to perform anterior rectus sheath plication. The concept of a sliding, mobile, sensate abdominal flap, created by liposuction and sustained by multiple neurovascular mesenteries, is also offered.     

Neophalloplasty in female-to-male transsexuals with the island tensor fasciae latae flap

In the past 60 years, several different procedures have attempted to achieve a postoperative neophallus that is as aesthetic and as functional as possible after penile amputation or sex reassignment. Recently, with improvements in free tissue transfer and microvascular technique, many free flap procedures have been developed with the goal of an aesthetically acceptable neophallus of adequate bulk that enables urination in a standing position and sexual intercourse, with minimal functional and aesthetic donor-site defects. Most authors currently agree that the method of choice for penile reconstruction is microsurgical free tissue transfer, although it does not always fulfill all of the aforementioned goals in a predictable manner. In fact, complete urethroplasty, penile rigidity, and donor-site disfigurement remain challenges, thus making this operation one of the most difficult in plastic surgery. The vascular anatomy of the lateral circumflex femoral artery, which we studied in 1991 with the anatomic dissection of 27 cadavers, gave us the idea to use a long tensor fasciae latae neurovascular island flap as a donor source for neophalloplasty. Grounds for the procedure and its surgical planning have been carefully evaluated with 10 additional fresh cadaver dissections. Since 1991, we have performed five neophalloplasties using this procedure; all patients were female-to-male transsexuals. In four cases, the healing was uneventful; in one case, there was a marginal necrosis of the flap because of poor venous drainage, probably from a twisting of the pedicle. The island tensor fasciae latae provides a safe and sensate flap for phalloplastic procedure and leaves a less conspicuous donor scar.     

Breast reconstruction using tissue expanders and implants in Hodgkin's patients with prior mantle irradiation.

Women treated for Hodgkin's disease with mantle irradiation have an increased risk for developing breast cancer. Typically, breast malignancy in Hodgkin's patients presents bilaterally in a younger age group. Skin flap ischemia, poor skin expansion, implant extrusion, capsular contracture, and poor cosmesis are common sequelae of tissue expander/implant breast reconstruction after breast irradiation for failed breast conservation therapy. This has led most surgeons to favor autologous tissue reconstruction in this setting. This study was performed to determine the efficacy of tissue expander/implant breast reconstruction in breast cancer patients who have been treated with prior mantle irradiation for Hodgkin's disease. A retrospective analysis of all breast cancer patients with a history of Hodgkin's disease and mantle irradiation treated with mastectomy and tissue expander/implant reconstruction between 1992 and 1999 was performed. There were seven patients, with a mean age of 35 years (range, 28 to 42 years). The average interval between mantle irradiation and breast cancer diagnosis was 16 years (range, 12 to 23 years). All patients underwent two-stage reconstruction. Textured surface tissue expanders were placed in a complete submuscular position at the time of mastectomy. Expansion was initiated 2 weeks after insertion and continued on a weekly basis until completion. Expanders were replaced with textured surface saline-filled implants as a second stage. Patients were evaluated for skin flap ischemia, infection, quality of skin expansion, implant extrusion, capsular contracture, rippling, symmetry, and final aesthetic outcome. Breast cancer was bilateral in five patients and unilateral in two. Two patients did not undergo simultaneous bilateral breast reconstruction because of metachronous cancer development. One of the patients had an initial transverse rectus abdominis muscle flap breast reconstruction, followed by a tissue expander/implant reconstruction of the opposite breast. The average follow-up was 3 years. Complications were limited to one case of cellulitis after implant placement that resolved with intravenous antibiotics. There were no cases of skin flap ischemia, poor skin expansion, or implant extrusion. Overall patient satisfaction was high and revisions were not requested or required. Symmetry was best achieved with bilateral implants. This study demonstrates the efficacy of tissue expander/implant breast reconstruction in patients treated with prior mantle irradiation. In this series, tissue expansion was reliable with low morbidity. Second-stage placement of permanent implants yielded good aesthetic results without significant capsular contracture. Mantle irradiation did not appear to compromise the prosthetic breast reconstruction. Tissue expander/implant breast reconstruction should remain a viable option in this category of irradiated patients.     

Tensor fasciae latae perforator flap for reconstruction of composite Achilles tendon defects with skin and vascularized fascia

The surgical management of large defects of the Achilles tendon and overlying skin is very demanding and necessitates, as a rule, a free vascularized graft. The ideal characteristics of a thin layer of skin and a strong tendon component, combined with a reliable blood supply and minimal morbidity at the donor site, have only been partially met by all previous grafts used in this situation. The authors performed reconstructions in five patients with large defects of the Achilles tendon and overlying skin by using a perforator flap derived from the tensor fasciae latae flap. A vascularized skin-subcutis-fascia lata flap could be raised by dissecting out two to three perforating arteries through the tensor fasciae latae muscle to the ascending branch of the lateral circumflex femoral artery; the muscle was left in situ in the process. All the flaps took well without complications. At final examination after an average of 20 months, the reconstructed Achilles tendon showed good functional results, although there was a 50 to 70 percent reduction in power during plantar flexion when compared with the normal side. A very good aesthetic result could be obtained after a debulking operation was performed on the skin flap.     

The thoracodorsal artery perforator flap: clinical experience and anatomic study with emphasis on harvest techniques

The thoracodorsal artery perforator flap is a relatively new flap that has yet to find its niche in reconstructive surgery. At the authors' institution it has been used for limb salvage, head and neck reconstruction, and trunk reconstruction in cases related to trauma, burns, and malignancy. The authors have found the flap to be advantageous for cranial base reconstruction and for resurfacing the face and oral cavity. The flap has been used successfully for reconstruction of traumatic upper and lower extremity defects, and it can be used as a pedicled flap or as a free tissue transfer. The perforating branches of the thoracodorsal artery offer a robust blood supply to a skin-soft-tissue paddle of 10 to 12 cm x 25 cm, overlying the latissimus dorsi muscle. The average pedicle length is 20 cm (range, 16 to 23 cm), which allows for a safe anastomosis outside the zone of injury in traumatized extremities; the flap can be made sensate by neurorrhaphy with sensory branches of the intercostal nerves. Vascularized bone can be transferred with this flap by taking advantage of the inherent vascular anatomy of the subscapular artery. A total of 30 pedicled and free flap transfers were performed at the authors' institution with an overall complication rate of 23 percent and an overall flap survival rate of 97 percent. Major complications, such as vascular thrombosis, return to the operating room, fistula formation, recurrence of tumor, and flap loss, occurred in 17 percent of the patients. Despite these drawbacks, the authors have found the thoracodorsal artery perforator flap to be a safe and extremely versatile flap that offers significant advantages in acute and delayed reconstruction cases.     

Reliability of the proximal skin paddle of the osteocutaneous free fibula flap: a prospective clinical study

The vascularization of the skin paddle of 20 osteocutaneous fibula free flaps in 20 patients was studied. All skin paddles were designed over the proximal and middle third of the fibula. A parallel vascularization of the skin was found in 10 cases. In these cases, an axial (septo)musculocutaneous perforator was found to originate high in the peroneal artery or even in the popliteal artery. This branch runs parallel to the peroneal artery without any further connections with it. In 5 of these 10 cases, no other skin perforators were located within the boundaries of the skin paddle. Harvesting such a flap in the traditional way by blind inclusion of a muscle cuff results in ligation of the supplying vessel of the skin paddle and subsequent loss of the skin. In this series, this would have been the case in 5 of the 20 patients (25 percent). This might explain the bad reputation of the skin paddle of this flap. The high prevalence of the described vascular configuration in a proximally designed skin paddle justifies à vue dissection of all musculocutaneous perforators up to their origin, unless one or more septocutaneous perforators are found within the boundaries of the flap.
