The oriental aging face: An evaluation of a decade of experience with the triangular SMAS flap technique in facelifting

The triangular SMAS flap technique was developed through a thorough understanding of the morphological and anatomical problems of the aging Oriental face. A unique manipulation of two triangular SMAS flaps—TSF-1 and TSF-2—permits three-directional lifting of the SMAS, which provides supportive and distributive lifting while reducing unwanted tension in the skin. TSF-1 is the excess portion of the main SMAS flap which results from cephalic lifting in the zygomatic area. TSF-2 is created from the excess portion produced by posterior advancement in the preauricular area, and is rotated to the postauricular area. Use of the TSF-1 flap involves complete excision, folding under, or free grafting. The retroauricular TSF-2 flap indirectly achieves platysmal plication. The author evaluates ten years of experience with the triangular SMAS flap technique and describes the entire aspect of the aging face in Orientals.The triangular SMAS flap technique was first presented at the 6th Congress of the International Society of Aesthetic Plastic Surgery, Tokyo, Japan, September 28–October 2, 1981     

Deep plane cervicofacial flap: a useful and versatile technique in head and neck surgery

BACKGROUND: Large oncosurgical defects of the cheek present a challenging reconstructive problem, especially when skin resections are combined with other procedures such as parotidectomy and/or neck dissection. METHODS: We present our experience with the deep plane cervicofacial flap (DPCFF) for reconstructing zone 1 (n=7), zone 2 (n=6), and zone 3 (n=5) cheek defects resulting from excision of primary cutaneous malignancies (n=13) and metastatic parotid (n=6) and/or neck (n=4) disease with skin involvement. The patients were between 65 and 88 years of age (mean, 76.7 years). The design of the flap was determined by the location of the defect and the need for simultaneous parotidectomy and/or neck dissection. Sixteen flaps were anteriorly based, whereas two were posteriorly based. RESULTS: Twelve patients underwent simultaneous parotidectomy (n=11) and/or neck dissection (n=10) and/or facial reanimation procedures (n=6). The size of the cutaneous defects ranged from 4 x 4 to 10 x 10 (mean, 5.6 x 5.3) cm. Eight patients received postoperative adjuvant radiotherapy to the primary site and/or parotid bed and neck. Superficial marginal flap necrosis occurred in one of the three patients who received definitive radiotherapy before salvage surgery and repair with DPCFF. Other complications included one hematoma, one ectropion, and one retraction of the lower eyelid. Apart from mild facial contour deficiency in two patients, excellent functional and cosmetic outcome with good skin color and texture match were achieved in all patients. CONCLUSIONS: The DPCFF is a versatile reconstructive technique in head and neck surgery. It provides a simple solution for a variety of cheek defects as an excellent alternative to regional or free tissue transfer. It can be used when simultaneous parotidectomy and/or neck dissection and/or facial reanimation procedures are required. This composite musculo-fascio-cutaneous unit is reliable with excellent vascularity, because it has an axial blood supply. Division of the facial suspensory ligaments during elevation of the flap in the sub-superficial musculo-aponeurotic system (SMAS) plane increases the mobility of this flap, which facilitates transfer.     

Free lateral supramalleolar flap transfer as a small,thin flap

Lateral supramalleolar flaps were elevated as free flaps and transferred with microvascular anastomoses in 3 patients. The peroneal vessels were used for the vascular anastomosis. In all patients, the flaps survived completely. The free lateral supramalleolar flap is thinner than the peroneal flap and is as thin as the radial forearm flap. This flap is useful when thin, small flaps are required, and may be a valuable alternative to the radial forearm flap because it necessitates less donor site morbidity.     

Rhytidectomy: Suprazygomatic and infrazygomatic SMAS treatment

The soft tissues of the face and neck are firmer above the zygomatic arch than below it. The SMAS should be treated differently according to where it is situated with respect to this arch. Above the arch, both the skin and the S-SMAS are firmly attached making it possible to correct both simultaneously by means of a flap that includes both layers. Beneath the zygomatic arch correcting the I-SMAS by stretching and relocating it enhances the contour of the jaw and neck and gives greater support to the skin. This provides for even better conformation when excess subcutaneous tissue is resected. An intermediate region exists between the corrected areas of the S-SMAS and the I-SMAS where the rhytidoplasty is exclusively performed through traction and rotation of the skin, but added resources diminish traction sequels.     

Upper transverse rectus abdominis flap: the flag flap

A flap is described that consists of skin from the upper abdomen, based on the ipsilateral rectus muscle and fed by the inferior epigastric vessel (the " flag flap"). The flap has an arc of rotation of 360 degrees, and its safety appears to be equal, and perhaps superior, to the lower transverse rectus abdominis flap. In addition, the " flag flap" avoids the potential disadvantage of creating a hernia below the semicircular line in the lower abdomen. The secondary defect is also acceptable. In all cases direct closure was possible by performing a reverse type of abdominoplasty and placing the scar at the submammary fold. The flap has been used in 8 patients for coverage of postradiation and postexcisional tumor defects in the lower trunk and extremities. The complications have been few, although it is not advised that the flap be used for reconstruction of the upper chest area by stretching the pedicle.     

Distally-based superficial sural flap: Advantages of the adipofascial over the fasciocutaneous flap

Abstract

The distally-based superficial sural flap has proved to be an easy and reliable method of reconstruction in soft tissue cover of the distal third part of the leg. There are two ways to prepare this flap: as a fasciocutaneous flap, which includes the fascia with the subcutaneous tissue including the skin; or as an adipofascial flap, which is made up of both the fascia and the subcutaneous adipose tissue. In the latter case, the flap is covered with a partial thickness skin graft either immediately after or at a later stage. The aim of this study was to assess the advantages and disadvantages of the two flaps. The adipofascial flap seems to be better, as it is associated with less donor site morbidity, improved quality of reconstruction, and fewer complications.     

Anterolateral thigh flap

The anterolateral thigh (ALT) flap is a versatile soft tissue flap. It can be harvested as a fasciocutaneous or myocutaneous flap. Vascularized fascia can be included or the pedicle may be harvested as a flow‐through flap. The flap can also be harvested incorporating multiple skin islands or as a chimeric flap incorporating separate skin and muscle components. When a large flap is needed, the entire lateral thigh can be harvested by combining the ALT with either the tensor fascia lata or the anteromedial thigh flap as a conjoined flap. Morbidity is remarkably minimal despite the availability of such generous amounts of tissue. The purported difficulty with the use of this flap is because of the anatomical variations that may render this flap unreliable. This paper clarifies the vascular anatomy of the flap and elaborates an approach to flap harvest that can be used to reliably harvest the flap in spite of the anomalies that may be encountered. © 2009 Wiley Periodicals, Inc.

The V-flap and the Berlin tulip flap: two new concepts in conventional flap techniques

Microsurgical operations are costly and technologically demanding. We have therefore developed new conventional flap techniques using state-of-the-art knowledge of skin anatomy and circulation. The V-flap is a combination of the V-Y advancement flap and two Limberg flaps [2]. Sixty patients treated by the new flap technique have shown a low rate of complication. Even when used in difficult regions of the body or in very large defects, the V flap has proven to be very effective. It has been adopted as a standard flap technique in our hospital. The Berlin tulip flap is another very reliable flap. To form the tulip flap, the outer corners of a subcutaneous pedicle flap are curved backwards. When detached, they can be transposed to the healthy tissue on the contralateral side. This completely relieves the midzone, which then can be safely closed in the same manner as a V-Y flap. The Berlin tulip flap is particularly useful for covering trunk defects and managing sacral ulcers in paraplegics.Correspondence to: E. Vaubel

Supercharged reverse-flow sural flap: a new modification increasing the reliability of the flap

The management of soft-tissue defects in the lower third of the leg and foot presents a considerable problem because of composite tissue defects, inadequate and tight local tissue for reconstruction, and poor circulation. Although the reverse sural flap is frequently preferred and is fairly reliable, some complications arising from the circulation may be encountered in large flaps or in diabetic patients. In the present study, we developed a new modification by supercharging the sural flap to reduce venous congestion and edema and to increase the reliability of the flap. We treated 3 patients (2 men and 1 woman) by utilizing a supercharged reverse sural flap. All flaps survived and healed uneventfully. We also suggest a new and more distinctive classification for supercharging and turbocharging, which defines the vessel type to be anastomosed and the relationship of the vessel to be anastomosed with the main vessel to the flap.     

Flag flap - Kite flap Dorsal metacarpal flap

The flag flap is a pedicled dorsal digital flap, combining a skin paddle (the “flag”) and a vascular pedicle (the flag “pole”). Its vascularisation depends on the dorsal metacarpal arteries (DMCA). It has been described in 1963, by Holevitch [1] with harvest of a cutaneovascular pole; it has been brilliantly modified in 1979 by Foucher et al. [2–4] under the form of a unipedicled “kite” flap, although we would like to point out that Vilain has been using it since 1952 [5]. Usually harvested from the dorsum of the metacarpophalangeal region of the index finger, this flap is reliable, but it is more uncertain and less movable at the level of the other digits. Owing to its small size, it proves useful in hand traumatology because it does not sacrifice any major vascular axis. The kite flap is considered as a sensory flap (presence of a nerve supply) with a two-point discrimination, which can be assessed from 11 to 16 mm [1–6].     

McGregor flap

Since it has been described in the early seventies [1], this flap has become an essential tool in reconstructive surgery, primarily due to the wide cutaneous surface it may replace. Its pediculate form is useful and it may be employed with significant benefit as free flap; it may even provide composite tissues. Also known as McGregor’s flap, groin flap, or iliofemoral flap, this axial pattern flap is based on the superficial iliac circumflex artery.     

Recycling a flap: making a perforator flap from a previous gluteal fasciocutaneous flap

We report a case of raising a previous gluteal fasciocutaneous flap again as a perforator-based flap to cover a recurrent defect. This case illustrates that conventional flap tissue with a preserved perforator can be recycled as a perforator flap, and that this method can be an efficient surgical option for recurrent defects.     

Use of the latissimus dorsi flap for recontouring and augmentation after TRAM flap breast reconstruction

The transverse rectus abdominis musculocutaneous (TRAM) flap is the most commonly used autogenous tissue flap for breast reconstruction. However, it may not provide sufficient volume in all patients to match the contralateral breast. Insufficient abdominal bulk or bilateral reconstructions limit the amount of tissue available for the TRAM flap. Partial flap loss from fat necrosis or radiation injury may result in contour deformities of the reconstructed breast. Additional soft-tissue augmentation and contouring may be necessary to produce adequate volume, contour, and symmetry. The authors present 7 patients who underwent latissimus dorsi flap reconstruction to correct volume and contour abnormalities that developed after TRAM flap breast reconstruction. Preservation of the serratus branch of the thoracodorsal vessels allows this flap to be used even after free TRAM flap reconstruction.     

Laboratory model of a microvascular free flap in the rat: the epigastric flap

BACKGROUND: Soft tissue defects are mostly managed surgically by free microvascular flaps. The progressive development of techniques and the availability and reliability of new different and free flaps encouraged this surgical approach. Thus, there is a constant need of free flap models to reproduce in laboratory. The experience with the use of the epigastric free flap in the rat as a laboratory model for microsurgical trainees is presented. In our microsurgical flap model the anastomoses were constantly performed on the femoral vessels. METHODS: The flap was used in 25 rats during the practical sessions of periodical experimental microsurgery courses. The main steps were: flap harvesting on the superficial epigastric vessels; flap anastomosis on the femoral vessels; pedicle section; microvascular anastomosis. RESULTS: The epigastric free flap showed to be an easy surgical model. The mean duration of the exercise was 2 hours and 11 minutes. These surgical times were considered acceptable to the requirement of a laboratory model. CONCLUSIONS: The epigastric free flap in the rat is a reproducible experimental model which is still up to date in microsurgical training.     

Use of the anterolateral thigh flap as an alternative to the rectus flap in obese and overweight patients

INTRODUCTION: Oncologic reconstruction in obese patients can be challenging. Donor tissues, such as the rectus flap, can be excessively bulky and result in significant cosmetic and functional deformities. Although the use of the anterolateral thigh (ALT) flap as an alternative to the radial forearm flap has been extensively described, few studies have evaluated the use of the ALT flap as an alternative to the rectus flap. The purpose of this study was to evaluate our experience with the ALT flap in overweight or obese patients. METHODS: A retrospective review was conducted of all ALT flaps performed over a 2-year period at Memorial Sloan-Kettering Cancer Center. All patients with a body mass index (BMI) >25 kg/m2 were identified and evaluated. RESULTS: Twenty-seven patients underwent ALT flap reconstruction during the study period. Of these, 11 patients were overweight (BMI, 25.1-30 kg/m2) or obese (BMI, >30 kg/m2). Reconstructions were performed for a variety of oncologic defects, including head and neck (n = 7), extremity (n = 2), chest wall (n = 1), and abdominal wall (n = 1). Complications were, in general, mild and infrequent. One patient experienced a minor infection, 1 patient had partial flap loss, and 2 patients had partial skin graft loss at the donor site. There were no flap losses. CONCLUSIONS: The ALT flap is a safe and reliable flap for reconstruction of diverse defects in overweight or obese patients. Large flaps can be designed and tailored to the defect by harvesting variable amounts of skin, subcutaneous tissues, fascia, and muscle. The ALT flap may be a good alternative to the rectus flap in overweight or obese patients.
