PMMC Flap Revisited and its Clinical Outcome in 150 Patients

  • 43 Accesses

Abstract

Introduction

Pectoralis myocutaneous flap remains the workhorse for the reconstruction of large defects in the head and neck region despite free flaps gaining popularity; because of its drawbacks such as long operating hours, high cost and special skill techniques, it is not used in most of the institutions. Even in our institution, free tissue transfers are carried out on a regular basis, but there is a definite scope and role for PMMC flap in reconstruction. We present our experience with pectoralis major myocutaneous flap in terms of postoperative complications, donor site morbidity, flap survival and long-term healing of the flap.

Materials and methods

In this study, 150 patients who underwent pectoralis myocutaneous flap reconstruction from 2008 to 2016 were analysed for postoperative complications like donor site morbidity, flap survival and long-term healing of the flap.

Results

On analysis of our data, it was found that the most common complication was wound dehiscence, which was seen in 25 patients(16%), followed by orocutaneous fistula in 15 (10%), wound infection and partial skin margin necrosis, which was seen in a maximum of 12 each(8%), hematoma in 5 (3%), and donor site wound dehiscence in 5 (3%), and there was no case of total flap failure or carotid blowout.

Discussion

We conclude that PMMC flap along with its modifications is the most cost-effective and associated with least complications.
