Evaluation of post total laryngectomy voice rehabilitation by Provox®2 voice prosthesis (preliminary study)

Authors

Abstract

Introduction: Tracheo-esophageal puncture (TEP) with inserting a silicon prosthesis is the gold standard for voice rehabilitation after total laryngectomy (TL). Provox® is an indwelling voice prosthesis which is widely used nowadays.
Objective: to evaluate the outcomes of Provox®2 voice prosthesis in vocal rehabilitation after total laryngectomy.
Patients and methods:  Sixteen patients who had inserted Provox®2 voice prosthesis after total laryngectomy were subjected to history taking, general ENT examination and neck examination. Patients were evaluated for voice outcome two months after the application of the Provox®2 by the maximum phonation time (MPT), Perceptual voice quality analysis by GRBAS scale, Speech intelligibility and Patient’s satisfaction.
Results: We found that the production of 100% intelligible voice with a good MPT and quality of voice (assessed by GRBAS scale) using a device with an average life of 375 days would be considered as favorable.
Conclusions: The use of Provox®2 voice prosthesis is a safe and satisfactory method for post total laryngectomy voice rehabilitation.
