RESUMO
Aim: To evaluate the current role of pectoralis major (PM) flap including the reasons for selecting it over free flaps. Materials and methods: All patients who underwent PM flap at Apollo Hospitals Ahmedabad during the 3-year period from January 2020 to December 2022 were included. Patient demographics, tumour characteristics and complications were studied and reasons for selecting pectoralis major flap were analyzed. Data was entered in Microsoft excel spreadsheet and analyzed using online statistical calculators. The p value of < 0.05 was considered statistically significant. Results: 57 patients underwent reconstruction with PM flap while 154 patients underwent free flap reconstruction. 54 were male and 3 were female. Median age was 51 years. PM flap was used for intraoral lining in 25 patients, and it was bilobed in 26 patients with full thickness cheek defect. Most common complication was wound infection seen in 10 patients. 5 patients developed marginal necrosis of the flap and 5 had donor site wound dehiscence. No complete flap loss was seen. During the same period, 15/154 (9.74%) patients with free flaps developed complete flap necrosis and this was statistically significant (p = 0.012). Reasons for choosing PM flap were also analyzed. 14 patients had major comorbidities, 18 had extensive disease, in 5 patients it was used for salvage post free flap failure, while 10 previously treated patients had unavailability of suitable vessels for anastomosis. 12 patients underwent PM flap due to financial constraints. Conclusion: Thus, PM flap is not obsolete and continues to maintain its place in head and neck reconstruction.
