Abstrakt: Reconstruction of large and complex defects arising from resection of advanced oral cancers requires free flaps or multi-staged reconstructions using a combination of pedicled flaps. Bipaddle (pectoralis major myocutaneous (PMMC) flap is a good alternative for reconstruction of such defects, especially in low-middle–income countries (LMIC). However, care should be taken while expanding its limits to avoid unnecessary morbidity. We discuss technical considerations while extending the PMMC flap design beyond the usual boundaries and analyse surgical and quality of life (QOL) outcomes in our patients with large (≥ 10 cm) oral cavity defects while using extended bipaddle PMMC flaps. We retrospectively analysed the results of 72 oral cancer patients with large buccoalveolar defects with at least one dimension ≥ 10 cm who underwent single-stage reconstruction using extended bipaddle PMMC flaps between January 2018 and December 2019. Total flap loss was seen in one patient and partial loss in 10 (13.8%) patients, while 18 (25.1%) patients had major complications (Clavien-Dindo grade III). Discharge from hospital was delayed beyond a mean of 6 days in 15 (20.8%) patients and the start of adjuvant treatment was delayed in 5 patients (6.9%). On univariate analysis, age > 50 years, female gender, the largest dimension and flap area were significant factors increasing morbidity. The QOL outcomes were acceptable. The satisfactory results from our series reaffirm that extended bipaddle PMMC flaps are a viable alternate option for such reconstructive challenges in resource-limited centres. However, age, gender, the defect dimensions and flap area should be taken into consideration while using this flap. [ABSTRACT FROM AUTHOR]
