ABSTRACT
Background and Objectives
s : To compare acoustic, aerodynamic analysis of voice and intelligibility score in patients with near-total laryngectomy and implantation of Provox prothesis. Material and Methods : In order to evaluate the voice characteristics, acoustic, aerodynamic parameter and speech intelligibility were measured in 5 patients after near-total laryngectomy, 5 patients after implantation of Provox prosthesis with total bility were measured in 5 patients after near-total laryngectomy, 5 patients after implantation of Provox prosthesis with total laryngectomy and 10 adults normal speaker. Acoustic analysis was carried out using CSL and aerodynamic analysis was carried out using Aerophon II. Speech sample was recorded and 10 listener was scored for speech intelligibility using a percentage of words correctly identified.
Results.
Fundamental frequency($F_0$), intensity, jitter, shimmer, maximal phonation time(MPT), subglottic air pressure were used for parameters for voice analysis. There were no significant difference between two group except on fundamental frequency and shimmer. The fundamental frequency was higher in patients with near-total laryngectomy and shimmer was higher in patients after implantation of Provox prosthesis with total laryngectomy. In addition, speech intelligibility was no significant difference between two groups.
Conclusion
: This results confirm that near-total laryngectomy and implantation of Provox prosthesis provides good voice rehabilitation.
