The composite anterolateral thigh flap for knee extensor and skin reconstruction

The simultaneous reconstruction of a skin defect and lost extensor mechanism of the knee joint is difficult. We present a 31-year-old male who lost the patella and had a 9 × 10 cm skin defect after a total patellectomy for an infected open patellar fracture. A composite anterolateral thigh (ALT) flap including vascularized skin and fascia lata (FL) was elevated. The FL was folded and sutured to the remaining patellar tendon. The skin flap covered the skin defect. The wound healed uneventfully. Thirty months later, the active range of motion of the knee joint was 0°–120° and the extension strength of the knee joint was normal. He could stand on his right leg and walk without assistance. The composite ALT flap is a valuable option in knee reconstruction after a total patellectomy.     

Pedicled anterolateral thigh flap for contralateral groin composite defect

Pedicled anterolateral thigh flap has been well described for ipsilateral groin defects. Its versatility depends on the intact femoral vessels. When the external iliac and the femoral vessels are absent, especially secondary to wide surgical tumour ablations in the groin region, ipsilateral ALT flap is not an option. Free flaps also are difficult because of lack of recipient vessels. We report a case of composite groin defect following wide resection of recurrent liposarcoma along with encased vessels which was covered with a pedicled anterolateral thigh flap from the opposite thigh. The technique of lengthening the vascular pedicle and medializing the pedicle, to effectively increase its reach to the contralateral anterior superior iliac spine without vascular compromise, is described.     

Modification of the anterolateral thigh free flap design for reconstruction after laryngo-pharyngoesophagectomy

The anterolateral thigh free flap (ALTFF) has become the favourable fasciocutaneous flap for reconstruction of laryngo-pharyngoesophagectomy (LPO) defects. Reconstruction of these defects can be challenging. We report our experience with a new flap design based on the traditional ALTFF template for single-stage reconstruction of circumferential LPO defects with anterior neck skin deficits in previously irradiated patients. The design uses the traditional tubed skin island to create the neopharynx and also utilises the natural dog-ears from the thigh as a second vascularised skin island that can be used to fill dead space or externalised to resurface the neck. This addresses the issues of monitoring the internal skin paddle and also of replacing anterior neck skin deficits with a single flap.Level of Evidence: Level V, therapeutic study.     

Monitoring a free anterolateral thigh flap for pharyngeal reconstruction

Aim: To describe a novel way of monitoring a buried fasciocutaneous anterolateral thigh (ALT) flap used for pharyngeal reconstruction. Methods: A tubed ALT flap was used to reconstruct a circumferential pharyngeal defect following resection of a carcinoma. An island of skin based on a separate perforator and externalized through the neck incision was used to monitor the flap. It was removed as a bedside procedure on the fifth postoperative day. Results: The externalized skin island allowed easy monitoring of the buried tubed free‐flap used to reconstruct the pharynx. Simple clinical parameters such as temperature, colour and capillary refill were used to monitor the flap instead of more complex and invasive methods. Conclusion: When feasible, a second skin island based on a separate set of perforator vessels provides an easy, safe and simple method of monitoring a buried free‐flap.     

Proximal pedicled anterolateral thigh flap for reconstruction of trochanteric defect

We describe our experience using the proximal pedicled anterolateral thigh (ALT) flap for the reconstruction of trochanteric defects. Seven ALT island flap procedures were performed in 6 patients between September 2006 and May 2007. Four of the 7 patients had trochanteric pressure sores because of paraplegia. In these patients, intramuscular perforators were dissected to raise a fasciocutaneous flap. Three myocutaneous flaps of the vastus lateralis muscle were used to treat osteomyelitis of the trochanter with implant extrusion. The mean follow-up was 7 months (range, 2-12 months), and all flaps survived. Trochanteric coverage with the proximal pedicled ALT flap gave excellent results. We conclude that the ALT flap is a reliable flap for trochanteric coverage.     

Head and neck reconstruction with anterolateral thigh flap.

OBJECTIVE: Our goal was to present our experience with the free anterolateral thigh flap for reconstruction of various cutaneous and mucosal defects of the head and neck. STUDY DESIGN: We conducted a retrospective review of 37 patients who underwent reconstruction between 1994 and 2002. Outcome measures included ethnicity, flap harvest technique, vascular anatomy, flap success, general surgical complications, and donor site morbidity. RESULTS: The majority of our patients were white (n = 33). The size of the 39 free anterolateral thigh flaps varied from 24 to 252 cm(2). There was 1 arterial failure and flap loss (2.6%) and 2 venous occlusions that were both salvaged. The donor site was closed primarily in 37 cases and with a split-thickness skin graft in 2 cases. CONCLUSIONS: This is the first report on using the free anterolateral thigh flap in whites. This free transfer has proved to be a versatile and reliable flap for reconstruction of the head and neck.     

Recontouring commissuroplasty after reconstruction of large defects after resections for head and neck cancer with commissure involvement using an anterolateral thigh flap

The aim of this study was to describe our technique for recontouring commissuroplasty after reconstruction of large, through-and-through perioral defects in patients with head and neck cancer with emphasis on functional and cosmetic outcome. This technique was used in 15 patients aged between 33 and 66 years. Recontouring required liposuction, arrow-headed advancement flap, and anchoring vector sutures. All patients had satisfactory functional and cosmetic results and healed without complication. Function was evaluated to find out whether the patient was free of drooling and able to accommodate more food postoperatively. Aesthetic evaluation was subjective, and the patients themselves decided using a visual analogue cosmesis scale. Our combined procedures provide a predictable way of creating a new oral commissure, improving postoperative drooling, and increasing the intraoral space after reconstruction.     

Use of the anterolateral thigh free flap for upper-extremity reconstruction

PURPOSE: The anterolateral thigh free flap (ALTF) first was reported in 1984 and has been used in large series with success for a multitude of clinical purposes. We describe our results with the ALTF in upper-extremity and hand reconstruction. METHODS: From 1996 to 2003 there were 15 patients who had reconstruction of the hand and upper extremity using the ALTF. The parameters used to assess the outcome of our series included the success rate of the flap as measured by flap survival rate and adequacy of skin coverage, ability to close the donor site primarily or necessity of a skin graft, complications associated with the flap, donor site, and non-flap-related complications such as pulmonary embolism. RESULTS: Of the 15 patients with an ALTF, 3 (20%) had a musculocutaneous perforator and 12 (80%) had a septocutaneous perforator. Two patients had a neurotized ALTF reconstruction. There were 4 complications related to the flap with 1 complete flap failure. The overall flap survival rate was 93%. The donor site was closed primarily in 8 patients (53%) and with a skin graft in 7 patients (47%). One donor site breakdown occurred. CONCLUSIONS: Our results show many advantages of the ALTF for upper-extremity reconstruction. Because of its versatility the ALTF is suited ideally for upper-extremity reconstruction and should be considered as part of the reconstructive ladder.     

Flow-through anterolateral thigh flap for a free osteocutaneous fibula flap in secondary composite mandible reconstruction.

Head and neck reconstruction after tumour ablation and radiotherapy often requires complex surgery. The need for free composite tissue transfer and the poor quality of the recipient site increase the level of difficulty substantially. We report a case in which the mandible, floor of the mouth and skin of the neck needed to be reconstructed in a heavily irradiated field. A single osteocutaneous fibula flap was insufficient to reconstruct the defect, and a free anterolateral thigh (ALT) flap was also used for external neck skin resurfacing. As the recipient vessels in the ipsilateral neck had been heavily irradiated the free ALT flap was used as an interposition conduit for the free osteocutaneous fibula flap enabling it to reach the healthy recipient vessels in the contralateral neck without needing vein grafts.
