Background:
The aim of the study was to describe a novel technique for reinforcement of salvage laryngectomy closure using a bipedicled musculofascial submental flap.
Methods:
A retrospective cohort study design identified patients who underwent salvage laryngectomy reinforcement with a bipedicled submental hammock flap between January 2008 and December 2016 were compared to salvage laryngectomy patients treated with primary closure of the neopharynx during the same time period. Pharyngocutaneous fistula rates were compared between groups.
Results:
Pharyngocutaneous fistula rate in the submental hammock group (2/31, 6.5%) was significantly lower compared to the primary closure group (14/45, 31%, P < .05).
Conclusion:
The bipedicled musculofascial submental hammock flap is a viable method for reinforcement of salvage laryngectomy defects. It has a favorable pharyngocutaneous fistula rate compared to primary closure alone and has unique advantages over conventional methods of reinforcement.
