Laryngeal reconstruction by complex hyoid bone flap after frontal partial laryngectomy / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>The aim of this study was to describe a new technique of combined hyoid bone and thyrohyoid membrane flap in laryngeal reconstruction after tumor resection, and to evaluate outcome.</p><p><b>METHODS</b>Six patients requiring an frontal partial laryngectomy for cancer were enrolled between September 2008 and August 2012.</p><p><b>RESULTS</b>Nasogastric feeding was initiated within 24 hours. The mean times to swallow batter, ability to drink water and removal of the nasogastric tube were 2.6, 5.5 and 6.3 days. All patients had good respiratory function. There were no deaths, and no reports of postoperative dyspnea or dysphagia. The vocal quality was satisfactory, slightly deeper and raspy, and the volume was weak when calling. The final follow-up assessment was in August 2012, and the overall mean follow-up period was 29.5months, range 14 to 47 months. Case two subsequently underwent total laryngectomy for recurrence in the paraglottic space, but there was no evidence of further tumor recurrence at the final assessment.</p><p><b>CONCLUSIONS</b>The combined muscle-pedicle hyoid bone and thyrohyoid membrane flap is a reliable graft for one-stage repair of laryngotracheal defects, providing effective repair of the mucosa and cartilage support. Vocal quality, swallowing function and ventilation after the procedure were favorable.</p>
