RESUMO
Background Anterolateral thigh (ALT) flap is the most common soft tissue flap used for microvascular reconstruction of head and neck. Its harvest is associated with some unpredictability due to variability in perforator characteristics, injury or unfavorable configuration for complex defects. Anteromedial thigh (AMT) flap is an option, but the low incidence and thickness restrict its utility. Tensor fascia lata (TFL) perforator (TFLP) flap is an excellent option to complement ALT. Its perforator is consistent, robust, in vicinity, and lends itself with the ALT perforator. Methods This study was an analysis of 29 cases with a free flap for head neck reconstruction with an element of TFLP flap from July 2017 to May 2021. Results All cases were primarily planned for an ALT reconstruction. There was absence of the ALT perforator in 16 cases but a sizable TFL perforator was available. In 13 cases, the complex defect warranted use of both ALT plus TFL in a conjoint (5), chimeric (5), and multiple (3) free flaps manner. Most common perforator location was septocutaneous between the TFL and gluteus medius. There was complete flap loss in two cases and partial necrosis in two. No adjuvant therapy was delayed. Conclusion TFLP can reliably complement the ALT/AMT axis. Chimeric ALT-TFL can be harvested for large, complex, multicomponent, and multidimensional defects.
RESUMO
BACKGROUND: Filarial lymphedema (FLE) is the most common cause of secondary lymphedema, with endemic prevalence in developing countries. FLE traditionally has been managed with antibiotics and decongestive therapy (DCT) in the early stage or excisional surgery at the late stage. Results of vascularized lymph node transfer (VLNT) in postoncologic lymphedema have been encouraging, and VLNT is a widely accepted surgical treatment. The authors advocate that the combined treatment of antibiotics, DCT, and vascularized submental lymph node (VSLN) transfer could produce objective and subjective improvement of early-stage lower limb FLE. METHODS: Between January of 2019 and January of 2020, patients with early-stage lower-limb FLE who underwent VLNT were retrospectively reviewed. VLNT was harvested from the submental region in all patients. Outcomes were assessed using volume improvement, frequency of cellulitis, and lymphoscintigraphy, along with subjective scoring questionnaire. RESULTS: Three men and one woman with an average age of 27 years (range, 25 to 29 years) were included. Two patients presented bilateral lymphedema. One patient was lost at 3-month follow-up and not included in the analysis. Patients showed an initial decrease in circumferential measurements after antibiotics and DCT of 2074 ± 471 cc (39% ± 9%). At a mean follow-up of 12.3 ± 6.2 months, further improvement of limb volume of 2389 ± 576 cc (45% ± 10%) was achieved following VSLN transfer. Lymphoscintigraphy demonstrated dye uptake by the VLNT with reduced dermal backflow and none of the patients had episodes of postoperative cellulitis. Patients reported excellent outcome on subjective scoring (average score, 9 ± 1) and returned to their daily activities without wearing compression garments. CONCLUSION: The authors' early experience showed that VSLN transfer may represent an effective treatment option in the multimodal approach to early-stage lower limb FLE.
