Results of Voice Rehabilitation With Provox Prosthesis and Factors Affecting the Voice Quality

摘要

Objectives. Voice prosthesis is the standard of care for postlaryngectomy voice rehabilitation. We aimed to assess functional outcomes of Provox voice prosthesis, to study the impact of several clinical factors (timing of Provox insertion, type of pharyngeal closure, requirement of reconstruction, performance of myotomy, and radiotherapy) on the functional outcomes, and to record the complications associated with Provox voice prosthesis.
