Repair of complex pharyngocutaneous fistula using a staged temporoparietal fascial flap.

INTRODUCTION

PCF is the most common major complication after salvage total laryngectomy (TL), especially for previously irradiated patients with laryngeal or hypopharyngeal cancer.

METHODS/

RESULTS

A 65-year-old woman presented with recurrent bilateral supraglottic SCC requiring salvage TL 5.5years after initial T1N0M0 epiglottic SCC resection. Her post-operative course was complicated by PCF development one month post-operatively and surgical fistula closure was delayed for adjuvant chemoradiotherapy. The fistula persisted despite local wound therapy, several primary closures, pectoralis flap reconstruction with multiple revisions, and extensive hyperbaric oxygen treatments. Given her prior history, she underwent a staged right temporoparietal fascial flap reconstruction for persistent complex fistula, with second-stage flap takedown and complete inset of the TPFF skin island into the PCF.

CONCLUSION

This case demonstrates the utility of staged TPFF in complex PCF repair, with minimal morbidity, especially in a patient with prior irradiation and flap use that complicates tissue availability.
