BACKGROUND: Lower trapezius myocutaneous flap (LTMF) is widely used for reconstructing head and neck defects. However, a single LTMF, even after pre-transfer tissue expansion, is often insufficient to cover defects involving the bilateral neck and chest wall. This study presents our experience with the use of bilateral pre-expanded LTMFs for repairing extensive cervicothoracic defects.
METHODS: A retrospective study was conducted of patients who underwent bilateral pre-expanded LTMF reconstruction between March 2013 and August 2024. Patient demographics, defect features, flap characteristics, and surgical outcome were recorded to assess the efficacy and safety of the procedure.
RESULTS: Ten patients underwent reconstruction of bilateral pre-expanded LTMF reconstruction. The median age was 18 years (range, 5-41 years). The median defect size was 222.5 cm 2 on the left (range, 85-390 cm 2 ) and 246 cm 2 on the right (range, 80-490 cm 2 ). Tissue expansion lasted 3.5-9.5 months. The median flap size was 420 cm 2 on the left (range, 150-660 cm 2 ) and 477 cm 2 on the right (range, 260-645 cm 2 ). Fourteen flaps were transferred through subcutaneous tunnels, while 6 were transferred through an open wound between donor and recipient sites in a propeller fashion. The donor sites were closed primarily in all patients. Complete flap survival was achieved in 9 patients, while 1 patient experienced flap tip necrosis.
CONCLUSIONS: Bilateral pre-expanded LTMFs represent a reliable reconstructive option for cervicothoracic defects, providing satisfactory functional and aesthetic outcomes.
