title: Reconstruction of hypopharyngeal and cervical esophageal defect after resection of hypopharyngeal carcinoma: a new technique based on the use of bilateral platysma myocutaneous flaps.
abstract: Commonly used procedures for reconstructing hypopharyngeal and cervical esophageal defects resulting from total laryngopharyngectomy (TL) are the gastric conduit or colon transposition as well as microvascularized free flaps. Herein we designed an alternative procedure utilizing bilateral platysma myocutaneous flaps (PMCFs) for the reconstruction of hypopharyngeal and cervical esophageal defects. This report summarizes the technical description of this procedure. TL and cervical esophagectomy were performed and bilateral PMCFs were harvested for reconstruction of hypopharyngeal and cervical esophageal defects in 25 patients aged between 46 and 73 years (mean 58.7 ± 16.2 years). All these patients had advanced-stage (IV) cancer with involvement of the cervical esophagus. Operative time ranged from 176 to 382 minutes (average 243 ± 91 minutes) and the mean intraoperative blood loss was 294 ± 119mL. There were six cases of anastomotic leak (24.0%) and two of them (8.0%) developed anastomotic stricture. Neither flap necrosis nor postoperative death was observed. The majority of our patients (68.0%) were restored to a normal unrestricted oral diet after surgery. The 3-year and 5-year actuarial survival rates were approximately 54.7% and 26.1%, respectively. We conclude that reconstruction of the cervical esophagus with bilateral PMCFs is a valuable method for treating advanced hypopharyngeal carcinoma.
