Objective:
This study aimed to investigate the effects of submental flap reconstruction during open horizontal partial laryngectomy (OPHL) on improving postoperative swallowing function.
Methods:
A total of 72 patients with supraglottic laryngeal cancer were retrospectively divided into 3 groups: group A, including patients (n=30) who underwent classic OPHL; group B, including patients (n=18) who underwent transoral laser microsurgery; and group C, including patients (n=24) who underwent OPHL with submental flap reconstruction. Swallowing function was assessed using the Water Swallow Test (WST) and the Chinese version of the MD Anderson Dysphagia Inventory (MDADI). Voice function was evaluated using the Chinese version of Voice Handicap Index-10, and the incidence of postoperative respiratory distress was recorded.
Results:
The WST revealed that group C had significantly superior swallowing function relative to groups A and B. Similarly, MDADI scores were significantly higher in the group C than those in groups A and B. No significant difference was identified in voice function among the 3 groups.
Conclusion:
Submental flap reconstruction during OPHL significantly improved postoperative swallowing function and reduced aspiration symptoms, making this technique a valuable surgical option that warrants further consideration.
