Objective: This study aimed to evaluate the impact of an onlay pectoralis major flap in reducing the incidence of pharyngocutaneous fistula after salvage total laryngectomy and determine the complications of pectoralis major flap reconstruction. Methods: A retrospective study was conducted of consecutive patients who underwent salvage total laryngectomy between 1995 and 2016. The pharyngeal defects were primarily closed with or without the pectoralis major flap. Results: Of 64 patients, 34 had primary pharyngeal closure alone (control group) and 30 received an onlay pectoralis major flap (pectoralis major flap group). The overall fistula rate was 15.6 per cent, with 17.6 per cent occurring in the control group and 13.3 per cent in the pectoralis major flap group (p = 0.74). The incidence rates of voice failure (p = 0.02) and shoulder disability (p < 0.001) were significantly higher in the pectoralis major flap group. Conclusion: The pectoralis major flap in salvage total laryngectomy did not decrease the pharyngocutaneous fistula rate, and the incidence of flap-related complications was high. Appropriate surgical technique and post-operative care may reduce the incidence of pharyngocutaneous fistula.
