Laser blepharoplasty with transconjunctival orbicularis muscle/septum tightening and periocular skin resurfacing: a safe and advantageous technique

Carbon dioxide (CO2) laser blepharoplasty with orbicularis oculi muscle tightening and periorbital skin resurfacing is a safe procedure that produces excellent aesthetic results and diminishes the occurrence of complications associated with skin and muscle resection in the lower lid, particularly permanent scleral show and ectropion. The authors present a review of 196 cases of carbon dioxide laser blepharoplasty and periocular laser skin resurfacing performed at their center from April of 1994 to September of 1998. Of these cases, 113 patients underwent four-lid blepharoplasty, 59 underwent upper lid blepharoplasty only, and 24 underwent lower lid blepharoplasty only. Prophylactic lateral canthopexy was performed in 24 patients. Concomitant procedures (brow lift/rhytidectomy/rhinoplasty) were performed in 92 patients. The carbon dioxide laser blepharoplasty procedure resulted in no injuries to the globe, cornea, or eyelashes. Combined with laser tightening of the orbicularis oculi muscle and septum and periocular skin resurfacing, the transconjunctival approach to lower blepharoplasty preserves lower lid skin and muscle. Elimination of the traditional scalpel skin/muscle flap procedure results in a dramatically lower complication rate, particularly with regard to permanent ectropion and scleral show. Laser shrinkage of the orbicularis muscle and septum through the transconjunctival incision enables the correction of muscle aging changes such as orbicularis hypertrophy and malar festoons. The addition of periocular resurfacing enables the correction of skin aging changes of the eyelid that are not addressed by traditional scalpel blepharoplasty. In addition, lateral canthopexy constitutes an important adjunct to the laser blepharoplasty procedure for the correction of lower lid canthal laxity.     

Lower eyelid blepharoplasty: analysis of indications and the treatment of 100 patients

Traditionally, lower lid blepharoplasty has been confined to a choice of skin or skin-muscle flap transcutaneous blepharoplasty. In the past decade, in particular, various new techniques and technologies have emerged, altering our ability to treat the lower eyelids. These techniques include transconjunctival blepharoplasty, a variety of canthopexy procedures, fat-conserving or fat-replacing methods, wedge excision, and laser resurfacing techniques, and they allow a more individualized approach based on variations in anatomical features and patient goals. A retrospective review of data for 100 consecutive patients (ranging in age from 30 to 80 years) who underwent lower eyelid procedures during a 12-month period is presented. Procedures were categorized as follows: lower lid blepharoplasty, 35 cases; lower lid transconjunctival blepharoplasty, 27 cases; lower lid transconjunctival blepharoplasty with laser resurfacing, 17 cases; lower lid laser resurfacing, 16 cases; tarsorrhaphy with lower lid operation, three cases; tarsorrhaphy with laser resurfacing, two cases. Two complications of retained fat pads (one medial and one lateral) were encountered and were addressed with a secondary operation using a transconjunctival blepharoplasty approach. The results indicate that laser treatment has become the predominant form of lower eyelid resurfacing and that transconjunctival blepharoplasty is now the most common surgical procedure for the lower eyelid. All of our tarsorrhaphy procedures were performed for patients who had previously undergone surgical treatment of the lower eyelids. An algorithm based on physical findings and these techniques has been developed, for appropriate tailoring of the procedure to each patient's specific concerns. With the availability of a variety of techniques, an individualized approach based on variations in anatomical features is feasible.     

Primary and secondary orbit surgery: the transconjunctival approach

The transconjunctival approach to the orbit is underutilized because of concern regarding inadequate exposure and higher postoperative rates of lower eyelid shortening and ectropion. All patients who had a transconjunctival incision performed for orbital surgery over the last 6 years (1990 to 1996) were studied. Patients who had a transconjunctival blepharoplasty were excluded. A total of 35 patients, average age 32 years, had 45 transconjunctival incisions performed. Lateral canthotomy or cantholysis was not done. Operations fell into three categories: fracture plating alone, 10 (22 percent); split-calvarial bone graft placement with or without plating, 26 (58 percent); and orbital decompression, 9 (20 percent). The overall incidence of ectropion was 6.7 percent (3 of 45). One patient (2 percent) had transient ectropion, and two patients (4 percent) had persistent ectropion, which required surgical correction. Ectropion occurred only in those lower eyelids that had a previous transcutaneous incision (3 of 18 = 17 percent). None occurred in those eyelids that had no prior incision or only a previous transconjunctival incision. The transconjunctival approach without a lateral canthotomy provides safe access to the orbit in eyelids that have not had a previous transconjunctival incision.     

Transconjunctival lateral canthopexy in Down's syndrome patients: a nonstigmatizing approach

In Down's syndrome patients, surgical correction of the palpebral fissure obliquity through an external approach may produce a red, slightly hypertrophic scar. A transconjunctival approach for this repair was used for 15 Down's syndrome patients aged 3 to 17 years (mean 8.7 years), and the results were compared with those in two boys aged 6 and 17 years who underwent correction by the external approach. Palpebral fissure inclinations were recorded using anthropometric measurements preoperatively and 6 months postoperatively. Inclinations were reduced significantly by either technique; however, often the precise degree of the improvement was clear only from the measurements rather than from photographs. Complications of the transconjunctival approach were few, and there were no problems with wound healing and no ocular injury. Transconjunctival lateral canthopexy is a safe, effective method that avoids a potentially stigmatizing external scar.     

Transconjunctival upper blepharoplasty

Transconjunctival lower lid blepharoplasty now has an established role as an option in rejuvenation of the lower eyelid. Transconjunctival upper lid blepharoplasty, or transconjunctival removal of medial upper eyelid fat, also has a role in rejuvenation of the upper eyelid. However, this is a rather limited role. We have found this approach safe and efficacious as a primary as well as a secondary procedure for removal of excess medial upper eyelid fat. We report on 20 patients who have undergone this operation: 5 as a primary procedure and 15 as secondary. There were no complications, no revisions, and the patients have been uniformly happy with their results.     

Breast Reconstruction with the free TRAM or DIEP flap: patient selection,choice of flap,and outcome

Recent reports of breast reconstruction with the deep inferior epigastric perforator (DIEP) flap indicate increased fat necrosis and venous congestion as compared with the free transverse rectus abdominis muscle (TRAM) flap. Although the benefits of the DIEP flap regarding the abdominal wall are well documented, its reconstructive advantage remains uncertain. The main objective of this study was to address selection criteria for the free TRAM and DIEP flaps on the basis of patient characteristics and vascular anatomy of the flap that might minimize flap morbidity. A total of 163 free TRAM or DIEP flap breast reconstructions were performed on 135 women between 1997 and 2000. Four levels of muscle sparing related to the rectus abdominis muscle were used. The free TRAM flap was performed on 118 women, of whom 93 were unilateral and 25 were bilateral, totaling 143 flaps. The DIEP flap procedure was performed on 17 women, of whom 14 were unilateral and three were bilateral, totaling 20 flaps. Morbidities related to the 143 free TRAM flaps included return to the operating room for 11 flaps (7.7 percent), total necrosis in five flaps (3.5 percent), mild fat necrosis in 14 flaps (9.8 percent), mild venous congestion in two flaps (1.4 percent), and lower abdominal bulge in eight women (6.8 percent). Partial flap necrosis did not occur. Morbidities related to the 20 DIEP flaps included return to the operating room for three flaps (15 percent), total necrosis in one flap (5 percent), and mild fat necrosis in two flaps (10 percent). Partial flap necrosis, venous congestion, and a lower abdominal bulge were not observed. Selection of the free TRAM or DIEP flap should be made on the basis of patient weight, quantity of abdominal fat, and breast volume requirement, and on the number, caliber, and location of the perforating vessels. Occurrence of venous congestion and total flap loss in the free TRAM and DIEP flaps appears to be independent of the patient age, weight, degree of muscle sparing, and tobacco use. The occurrence of fat necrosis is related to patient weight (p < 0.001) but not related to patient age or preservation of the rectus abdominis muscle. The ability to perform a sit-up is related to patient weight (p < 0.001) and patient age (p < 0.001) but not related to preservation of the muscle or intercostal nerves. The incidence of lower abdominal bulge is reduced after DIEP flap reconstruction (p < 0.001). The DIEP flap can be an excellent option for properly selected women.     

Extensor digitorum brevis as an island flap in the reconstruction of soft-tissue defects in the lower limb

The extensor digitorum brevis island flap is a versatile and robust flap able to provide adequate bulk and coverage in soft-tissue defects of the lower limb. The donor-site deformity is limited to the necessary scar needed to approach and rotate the muscle. An anatomic study was performed in 10 fresh cadavers and consisted of two parts: study of the muscle flap itself, and examination of skin vascularization. Methylene blue and Salmon's mass (radiopaque) were injected through the three main arteries of the leg. Muscle and cutaneous staining were noted. Clinical applications of this flap are reported. These resulted in successful healing of the defect with good aesthetic and functional results on both recipient and donor sites. Long-term follow-up was maintained for up to 21 months.     

Expanded applications for transconjunctival lower lid blepharoplasty.

There has been a recent upsurge in interest in the transconjunctival approach for lower lid blepharoplasty. Initial reports have focused on the young patient with isolated fat prominence. We describe our experience with transconjunctival lower lid blepharoplasty in 104 patients over the past 2 years. There have been no instances of prolonged lower lid retraction problems, presumably related to leaving the skin, orbicularis, and orbital septum intact. Our experience with expanding the indications for the transconjunctival approach to include patients with fine skin wrinkling as well as frank skin excess has been extremely favorable. We conclude that the skin excess is often more apparent than real, with the skin being necessary to recontour the lower eyelid after fat excision. Although skin excision may be required during the initial procedure or at a later stage, patients with apparent skin excess need not be excluded from consideration for transconjunctival lower lid blepharoplasty.     

Anterolateral thigh flap for postmastectomy breast reconstruction

Most postmastectomy defects are reconstructed by use of lower abdominal-wall tissue either as a pedicled or free flap. However, there are some contraindications for using lower abdominal flaps in breast reconstruction, such as inadequate soft-tissue volume, previous abdominoplasty, lower paramedian or multiple abdominal scars, and plans for future pregnancy. In such situations, a gluteal flap has often been the second choice. However, the quality of the adipose tissue of gluteal flaps is inferior to that of lower abdominal flaps, the pedicle is short, and a two-team approach is not possible because creation of the gluteal flap requires that the patient's position be changed during the operation. In 2000, five cases of breast reconstructions were performed with anterolateral thigh flaps in the authors' institution. Two of them were secondary and three were immediate unilateral breast reconstructions. The mean weight of the specimen removed was 350 g in the three patients who underwent immediate reconstruction, and the mean weight of the entire anterolateral thigh flap was 410 g. Skin islands ranged in size from 4 x 8 cm to 7 x 22 cm, with the underlying fat pad ranging in size from 10 x 12 cm to 14 x 22 cm. The mean pedicle length was 11 cm (range, 7 to 15 cm). All flaps were completely successful, except for one that involved some fat necrosis. The quality of the skin and underlying fat and the pliability of the anterolateral thigh flap are much superior to those of gluteal flaps and are similar to those of lower abdominal flaps. In thin patients, more subcutaneous fat can be harvested by extending the flap under the skin. Use of a thigh flap allows a two-team approach with the patient in a supine position, and no change of patient position is required during the operation. However, the position of the scar may not be acceptable to some patients. Therefore, when an abdominal flap is unavailable or contraindicated, the creation of an anterolateral thigh flap for primary and secondary breast reconstruction is an alternative to the use of lower abdominal and gluteal tissues.     

Single eyelid incision for exposure of the zygomatic bone and orbital reconstruction

Experience with a single lower eyelid incision with mobilization of the lateral canthus is described for exposure of the zygoma, lower and lateral orbit, and zygomaticofrontal suture. The incision may be either subciliary with a skin-muscle flap or transconjunctival. Both require mobilization of the canthus. Reattachment of the canthus is not required in acute zygomatic fracture treatment but is preferred for secondary orbital reconstruction or in patients in whom a simultaneous coronal incision is employed. The approaches described reduce cutaneous scarring and provide generous exposure of the lower and lateral orbit. Predictable and improved aesthetic results are routinely achieved.     

The external oblique flap for reconstruction of the rectus sheath.

Despite the availability of synthetic materials and distant fascial flaps, primary closure of ventral abdominal defects with contiguous tissues remains the preferred solution. Increased experience with such defects in the lower abdomen, particularly at the time of bilateral rectus muscle transposition, led in 1985 to the investigation of an external oblique abdominis flap for closure of the anterior rectus sheath. From October of 1985 to October of 1990, 33 patients underwent repair of bilateral lower rectus abdominis defects with the help of bilateral external oblique flaps. Each of the patients had undergone synchronous chest or breast reconstruction using a transverse rectus abdominis musculocutaneous flap including bilateral rectus muscle pedicles. Although all patients in this study had undergone double-pedicle rectus muscle procedures, not all patients having had double-pedicle rectus muscle procedures required this maneuver. External oblique flaps were performed at the time of rectus sheath repair only if fascia could not be approximated without tearing. After closure of the bilateral paramedian defect, synthetic mesh overlay was added only if the direct closure still appeared excessively tight. At the time of advancement of the external oblique muscle and fascia, the internal oblique abdominis muscle and lateral cutaneous nerve of the thigh were preserved. Of the 33 patients who underwent this procedure, 7 required the addition of mesh overlay. Thirty-two patients healed uneventfully with a remarkably solid ventral abdominal wall. One patient developed an early postoperative hernia subsequent to a major and prolonged abdominal-wall infection and abscess. Patient follow-up ranged from 1 to 36 months, with a mean of 12 months.(ABSTRACT TRUNCATED AT 250 WORDS)     

Two new cutaneous free flaps: the medial and lateral thigh flaps

Two new cutaneous free-flap donor areas are described on the medial and lateral sides of the thigh. The medial thigh flap is supplied by an unnamed artery from the superficial femoral artery and is drained by the accompanying venae comitantes. Its nerve supply is from the medial femoral cutaneous nerve. The lateral thigh flap has its vascular pedicle from the third perforating artery of the profunda femoral artery and its accompanying vein. The lateral femoral cutaneous nerve provides sensation over the area. These flaps provide a large surface area of both skin and subcutaneous tissue without the usual bulk of subcutaneous fat and muscle. Their desirable features include long vascular pedicles with large vessel diameters and potential of being neurovascular flaps with specific sensory nerve supply and predictable anatomy. The principal disadvantage is that the donor site may leave a slight contour defect with primary closure or require grafting when a large flap is taken. We predict that these flaps will become important donor sites for reconstructive problems requiring resurfacing of cutaneous defects in various anatomic areas.     

Fibular osteoseptocutaneous flap: anatomic study and clinical application

The vascularized fibular graft has been expanded to an osteoseptocutaneous flap by including a cutaneous flap on the lateral aspect of the lower leg. The cutaneous flap can serve not only for postoperative monitoring of the grafted fibula, but also as extra skin coverage to replace substantial skin defects or prevent tight closure of the wound. From anatomic studies of 20 cadaver legs and 15 clinical cases, it has been possible to demonstrate adequate circulation to the skin of the lateral aspect of the lower leg from the septocutaneous branches of the peroneal artery alone. This finding has allowed the development of a new concept and technique to elevate the fibula as an osteoseptocutaneous flap for reconstruction which provides the following advantages: Elevation of the fibular osteoseptocutaneous unit is easy and fast. The cutaneous flap of the fibular osteoseptocutaneous unit can slide almost freely while attached to the paper-thin posterior crural septum without being tethered by a bulky muscle cuff, facilitating the setting of the fibular osteocutaneous flap when the bone and skin are widely separated. Intraoperatively, in a situation in which it is necessary to change from originally selected recipient vessels to ones more suitable, the thin posterior crural septum can be folded around the fibula allowing more flexibility in choice of recipient vessels. The fibular osteoseptocutaneous flap meets the criteria outlined for composite tissue reconstruction of defects of the extremities.(ABSTRACT TRUNCATED AT 250 WORDS)     

Lower blepharoplasty using bony anatomical landmarks to identify and avoid injury to the inferior oblique muscle

In the resection of redundant orbital fat during lower blepharoplasty, selective excision is performed from the medial, central, and lateral compartments. During transcutaneous blepharoplasty, the inferior oblique muscle is susceptible to injury because of its intimate association between the medial and central compartments. When performing a transconjunctival approach, the inferior oblique muscle is even more susceptible to injury because it lies in the direct path of dissection for fat pad exposure. Injury to the inferior oblique muscle can result in symptoms ranging from transient diplopia to a more debilitating permanent strabismus. Fresh cadaver heads were used to identify bony anatomical landmarks that would help to more accurately define the origin and body of the inferior oblique muscle. The orbital rim, infraorbital foramen, and supraorbital notch were chosen as guideline landmarks. The origin of the inferior oblique muscle was designated with respect to the above structures, and the muscle course was delineated. The inferior oblique muscle originates on the orbital floor, 5.14 +/- 1.21 mm posterior to the inferior orbital rim, on a line extending from the infraorbital foramen to 10 +/- 0.9 mm inferior to the supraorbital notch along the supramedial orbital rim. The muscle belly extends from this origin to its insertion into the posterolateral globe in an oblique direction toward the lateral canthal area. Identification of the orbital rim, infraorbital foramen, and supraorbital notch more accurately localizes the origin and course of the inferior oblique muscle, which may facilitate fat resection during lower blepharoplasty by preventing morbidity associated with inferior oblique muscle injury.     

Lateral canthal anchoring

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Understand the principles involved in canthal support for patients undergoing cosmetic and reconstructive surgery. 2. Understand the variations in surgical techniques required to perform canthal anchoring in differing patients. 3. Describe the significance and techniques of canthal anchoring (canthoplasty and canthopexy) as they relate to cosmetic and reconstructive lower lid surgery. 4. Describe the effect of canthal anchoring on the function of the upper and lower lids and eyelid fissure shape. Any surgeon performing cosmetic or reconstructive surgery procedures on the lower lid or midface through the lower lid should be comfortable with canthal anchoring procedures. Appropriate canthal anchoring is effective in preventing postoperative lower-lid malposition, in ensuring eyelid closure, and in improving or maintaining proper eye shape. In many patients, a canthopexy (nonlysis canthal anchoring) is effective. However, in patients with significant horizontal laxity, cantholysis with appropriate lid shortening is required. It should be remembered that canthal anchoring, no matter how well performed, will not prevent severe lower-lid complications in cases of over-resection of lower-lid skin and of poorly performed midface procedures that do not support the lower lid and cheek.     

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.     

Primary reconstruction of complex midfacial defects with combined lip-switch procedures and free flaps.

Free flaps are generally the preferred method for reconstructing large defects of the midface, orbit, and maxilla that include the lip and oral commissure; commissuroplasty is traditionally performed at a second stage. Functional results of the oral sphincter using this reconstructive approach are, however, limited. This article presents a new approach to the reconstruction of massive defects of the lip and midface using a free flap in combination with a lip-switch flap. This was used in 10 patients. One-third to one-half of the upper lip was excised in seven patients, one-third of the lower lip was excised in one patient, and both the upper and lower lips were excised (one-third each) in two patients. All patients had maxillectomies, with or without mandibulectomies, in addition to full-thickness resections of the cheek. A switch flap from the opposite lip was used for reconstruction of the oral commissure and oral sphincter, and a rectus abdominis myocutaneous flap with two or three skin islands was used for reconstruction of the through-and-through defect in the midface. Free flap survival was 100 percent. All patients had good-to-excellent oral competence, and they were discharged without feeding tubes. A majority (80 percent) of the patients had an adequate oral stoma and could eat a soft diet. All patients have a satisfactory postoperative result. Immediate reconstruction of defects using a lip-switch procedure creates an oral sphincter that has excellent function, with good mobility and competence. This is a simple procedure that adds minimal operative time to the free-flap reconstruction and provides the patient with a functional stoma and acceptable appearance. The free flap can be used to reconstruct the soft tissue of the intraoral lining and external skin deficits, but it should not be used to reconstruct the lip.     

TRAM flap breast reconstruction: tumescent technique reduces blood loss and transfusion requirement

The tumescent technique has been shown to be efficacious in reducing both operative and postoperative bleeding without significant deleterious side effects in suction lipectomy. In this study, the effects of the tumescent technique on postoperative complications in transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction are investigated. All women who underwent a TRAM flap breast reconstruction by the senior author (J.B.) at the Emory Clinic during the years 1990 to 1996 were pooled (n = 386). Any woman who had a preincision infiltration of 0.25% epinephrine-containing saline solution (>200 cc) around the donor site was included in the tumescent group (n = 59). Medical records were reviewed, and rates of partial flap loss, fat necrosis (> or =10 percent flap volume), flap full-thickness skin loss, donor-site complication (skin loss, hernia, or infection), and blood transfusion were determined. Group rates were compared. The infiltrated group had a significantly lower transfusion rate as compared with the control group (0.34 units versus 1.32 units, p < 0.001). The rates of partial flap loss and fat necrosis were less in the tumescent group, but not significantly (0 percent versus 4 percent, p = 0.232; and 1.7 percent versus 10.4 percent, p = 0.058). There were no significant differences in the incidence of full-thickness skin loss or donor-site complications. Donor-site infiltration before incision with a 0.25% epinephrine-containing saline solution significantly reduced the transfusion requirement in TRAM flap breast reconstruction patients without adversely affecting either breast mound or abdominal donor-site complication rates.     

Transblepharoplasty lower eyelid and midface rejuvenation: part I. Avoiding complications by utilizing lessons learned from the treatment of complications

Transblepharoplasty midface elevation has become a common aesthetic procedure in recent years. As new techniques have been utilized, complications have arisen. Management of these referred complications has resulted in the development of a technique that elevates the midface and restores the normal position and shape to the lower eyelid with minimal postoperative problems. Four principles must be followed to achieve satisfactory results. The orbicularis oculi/orbital septum bond must not be altered in midface surgery. The lateral canthus must be reattached to its normal anatomic location at the lateral orbital rim if there is lateral canthal tendon laxity. The orbital fat should be addressed via a transconjunctival approach, when necessary, to prevent middle lamella inflammation and orbital septum retraction. A suture at the inferior lateral orbital rim simulating the orbitomalar ligament, as well as orbicularis oculi muscle sutures, elevates the midface. Utilizing these steps, the midface and lower eyelid can be satisfactorily repositioned with minimal complications. This surgical approach can be utilized in all appropriate candidates but is especially useful in reoperative cosmetic surgery patients and the older patient population.     

Subciliary versus subtarsal approaches to orbitozygomatic fractures

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Describe the anatomic differences in the subciliary versus the subtarsal approach. 2. Discuss the difference between the "skin-only" and the "skin-muscle flap" variations of the subciliary approach. 3. Discuss the potential complications of both approaches. 4. Discuss the advantages of the subtarsal approach versus the subciliary approach. Many incisions have been described for approaches to orbitozygomatic fractures, the most frequently used being the subciliary incision with its modifications, the subtarsal incision, and the transconjunctival incision with or without lateral canthotomy. Each of these approaches has its advantages and disadvantages that may make it more or less appealing to use depending on the patient's age and severity of fracture. A balance must be struck between adequate exposure and acceptable cosmetic result. This article reviews the literature with particular respect to the transcutaneous approaches of subciliary versus subtarsal techniques in the treatment of orbitozygomatic fractures.
