Background and Objectives: The goals of laryngeal reconstruction have been prevention of aspiration, production of a functional voice, and maintenance of an adequate airway for decannulation. It is generally believed that the reconstruction of the glottic region after vertical partial laryngectomy (VPL) can improve laryngeal function. The objective of this study is to evaluate of voice function after VPL with mucosal flap and fat graft reconstruction.
Materials and Methods: From 1994 to 2006, 13 patients, who had been treated with VPL with mucosal flap and fat graft reconstruction. The voice characteristics, acoustic, aerodynamic parameter were measured in 13 patients after vertical partial laryngectomy with mucosal flap and fat graft reconstruction. Acoustic analysis was carried out using Computerized Speech Lab (CSL) and aerodynamic analysis were carried out using Aerophon II,3 months and 12 months after surgery.
Results: The GRBAS scale, jitter, shimmer, NHR were improved as time goes on after surgery. But, maximum phonation time was shortened after surgery and there is no significant differences between before and after surgery in mean flow rate.
Conclusion: The voice function of the mucosal flap and fat graft reconstruction after VPL were satisfactory. This can be an excellent reconstruction method after vertical partial laryngectomy.
