Case Reports of Two Unusual Donor Site Complications of the Pectoralis Major Myocutaneous Flap and Literature Review

The pectoralis major myocutaneous flap (PMMF), once considered a workhorse flap for head and neck reconstruction, is still used for a wide range of head and neck reconstruction in the era of microvascular free tissue transfer flap (MFTF) for many reasons including low donor site morbidity. Numerous studies have reported the flap-related complications of PMMF in depth but have seldom discussed the donor site complications in detail. This article reports 2 unusual donor site complications and reviews the published data on general donor site complications resulting from PMMF use.
