title: Hypopharynx and larynx defect repair after resection for pyriform fossa cancer with a platysma skin flap.
abstract: We used a platysma skin flap to repair larynx and hypopharynx defects to improve postoperative laryngeal function in patients with pyriform fossa cancer. Larynx-sparing surgery and postoperative radiotherapy were used in 10 patients with pyriform fossa cancer. The surgical approaches of lymph node dissection of the neck, vertical partial laryngectomy, and pyriform fossa resection were adopted, and a platysma skin flap was used to repair the resulting defects. In this group, the overall 3-year survival rate was 75% according to the Kaplan-Meier analysis, and the local control rate was 90%. Additionally, all patients were able to speak fluently with mild-to-moderate hoarseness. The tracheal tube was removed in all cases. Laryngeal fistulas were observed in 1 patient during radiotherapy. In conclusion, a platysma skin flap can be used to rebuild the larynx and hypopharynx in larynx-sparing resection for pyriform fossa cancer. These patients can obtain good postoperative function in swallowing, breathing, and pronunciation.
