Pectoralis major myocutaneous (PMMC) flap is versatile flap used for reconstruction of various head and neck defects created after excision of tumors. Due to the rapid advancement of reconstructive microsurgery, micro vascularised free flap transfer is becoming the main method of head and neck reconstruction. Presently PMMC flap reconstruction is used as an option for salvage surgery post free flap transfer failure and also in patients who are poor candidates for free flap transfer. However in developing countries like India where there are limited resources and the patient's presents in advanced stage of the disease PMMC flap is a viable option for reconstruction. Aim is to study the outcome of PMMC flap reconstruction in head and neck malignancy. A prospective analysis was done with 20 patients who underwent wide local excision with marginal or hemi mandibulectomy with PMMC flap reconstruction and neck dissection from January 2017 to January 2019 in tertiary care center. Follow up was done for every 2 weeks for first 2 months, then every month for a period of 6 months. Out of all the patients who underwent PMMC flap reconstruction, 2 patients developed partial flap necrosis, 1 had wound dehiscence and fistula and 1 patient had local recurrence. For remaining patients no complications were noted in the follow up period.
