Summary: Oral cancer often presents at an advanced stage, requiring extensive resection and complex reconstruction, such as free tissue transfers, which may not be available in a remote or resource-constrained facility. The common alternative in these cases is the use of the workhorse flap, the pectoralis major myocutaneous (PMMC) flap for lining and a second regional flap for cover. The results are variable, increase operative time and cost, and may cause additional donor site morbidity.We present a series of patients who underwent reconstruction for complex oral cavity and neck defects with a single PMMC flap with a unique design, folded or bipaddled to serve as both lining and cover. Pre- and post-operative data pertaining to patients with oral cancer who were selected to undergo bipaddled PMMC flap reconstruction in our unit between January 2017 and July 2019 were collected and analysed.Of the 41 patients, 28 were males and 13 were females. The surgical resection involved full-thickness excision of primary tumour and involved skin (face or neck) for oral cancers. The size of skin paddle harvested ranged from 8 to 15 cm horizontally to 6 to 22 cm vertically. Usually, the distal part of the skin paddle formed the mucosal lining and the proximal formed the skin cover. Complication rates in the immediate postoperative period and on initial follow-up visits were comparable to a conventional PMMC flap.Reconstruction of complex head and neck defects requiring mucosal lining and skin cover can be achieved with a single stage, bipaddled PMMC flap, a reliable and easily learnt alternative to technically demanding free tissue transfers. The complication rate observed in our series is remarkably low, even in females. With a proper design of the flap and appropriate orientation of the skin paddle, excellent results can be achieved with a bipaddled PMMC flap. |
