Abstract

Objective: To evaluate the effectiveness of reconstructing large defects in the head and neck region using the Pectoralis muscle skin flap. Subejct and method: A retrospective combined with prospective clinical intervention, cross-sectional description and longitudinal follow-up on 16 patients who underwent defect reconstruction using the major pectoralis muscle skin flap at the Center for Craniofacial and Plastic Surgery, 108 Military Central Hospital from January 2021 to February 2024. Result: The patients had an average age of 71.8 years, ranging from 62 to 78 years old. 87.5% of patients had comorbidities. The causes of the defects were post-cancer resection (56.3%), necrosis after radiotherapy (25%), and failure of previous free flap reconstruction (18.7%). Complex defects accounted for 68.7%. The major pectoralis muscle skin flap had a width ranging from 6-13cm, length from 12-22cm, and an average pedicle length of 18.3cm. No flap underwent complete necrosis, two flaps (12.5%) having partial necrosis and 5 flaps (31.3%) showing non-union at the initial surgery site. 68.8% of patients were satisfied or very satisfied. Conclusion: The use of the major pectoralis muscle skin flap for reconstructing large defects in the head and neck region is a safe, easily performed technique with a high success rate. This technique is indicated for patients with multiple comorbidities, those unable to undergo microsurgical techniques, or those with previously failed free flap reconstructions.
