PMMC flaps for reconstruction of oral defects in the age of microvascular flaps: A developing nation perspective

Abstract

Purpose: The purpose of this study was to compare Pectoralis major myocutaneous flap (PMMC) and Free flaps for reconstruction of post ablative defects in patients undergoing treatment for oral squamous cell carcinoma and to understand the reasons for choosing each from a developing nation perspective. Material and methods: In the present study, a retrospective study was conducted of the patients treated by either free flaps or PMMC flaps for reconstructive procedures over a five year period in the Department of Oral and Maxillofacial Surgery, Shri Guru Ram Das Institute of Dental Sciences and Research. Results: Out of 90 PMMC flaps, 44 patients (48.8%) had reconstruction due to lack of micro vascular facility at the center, in 39 patients (43.3%) due to financial constraints and in 7 patients (7%) due to associated comorbities. The overall complication rate in PMMC group was 30% as compared to 28% in Free Flap group. Total flap loss was seen in 3 flaps (2 microvascular and 1 PMMC) while marginal necrosis of skin paddle was seen in 12 patients (13%) in the PMMC group. Conclusion: Though, the selection of PMMC flap over free flap was influenced by many factors, results of this study suggest that PMMC flap still has a major role in post-ablative defect reconstruction even in this era of free flaps, especially in developing countries like India.
