Assessment of Vocal Function

  • Nobuhiko Isshiki

Abstract

Assessment of vocal function is essential in deciding the type of surgery that is indicated, intraoperatively which procedure should be taken in response to the vocal change, and postoperatively the effect of surgery on the voice. The description of the examinations here is confined only to those that are practical and normally required for surgery. For details, the reader is referred to works such as by Hirano (19810, Wendler and Seidner (19871), and Baken (19871). Voice recording is made on audio or videotape together with a laryngeal video-picture for later analysis, comparison, and discussion. The information is essential in determining the underlying mechanism for a given hoarse voice, especially whether any rheological change of the vocal cords, e.g., increased stiffness, is involved or not.
