Abstract
Surgical resection of hypopharyngeal cancer often affects laryngeal function. The aim of this study is to assess the reliability and efficacy of free skin flap transfer after partial hypopharyngectomy with laryngeal preservation. This study designs a retrospective analysis. The subjects were 54 patients who underwent free skin flap reconstruction immediately after partial pharyngolaryngectomy or hypopharyngectomy with laryngeal preservation. The defects were classified into four types based on the location of the hypopharyngeal defect. Functional results were evaluated by routine physical examination findings and parameters related to swallowing function and X-ray barium deglutition examination. Perioperative mortalities and morbidities were reviewed. There were no perioperative mortalities and 98% of the flaps survived. Forty-three patients (80%) were able to eat an unrestricted diet and experienced no aspiration. Restriction of the diet was significantly associated with the extent of oesophageal mucosal resection. In conclusion, free skin flap reconstruction is confirmed to be a safe and effective strategy to maintain laryngeal function and good quality-of-life.
