An Investigation of Reliability of the Sunderland Tracheosophageal Voice Perceptual Scale.

Background: The Sunderland Tracheosophageal Voice Perceptual scale (SToPS) is the only perceptual rating scale designed specifically for tracheosophageal voice [Hurren et al.: Clin Otolaryngol. 2009 Dec; 34(6): 533-8].

Evaluating the effect of different voice prostheses on alaryngeal voice quality.

Objective: To investigate the difference between voice prostheses in terms of voice quality as experienced by patients and as judged by expert raters.

Methods: Subjects had up to six voice prostheses placed in a random order. A voice sample was elicited for each patient on each prosthesis.

Double Blind Study Investigating the Effect of Different Voice Prostheses on Ease of Swallowing and Residue Post Laryngectomy.

Voice prostheses have been examined for their effect on voice production but there is little datum on their effect on swallow function. This study investigated the difference between six commonly available voice prostheses in terms of swallowing. Laryngectomy patients had up to six voice prostheses placed in a random order over two visits.

An Investigation of the Post-laryngectomy Swallow Using Videofluoroscopy and Fiberoptic Endoscopic Evaluation of Swallowing (FEES).

This study investigates the post-laryngectomy swallow. Presence and degree of residue on the post-laryngectomy swallow as observed on videofluoroscopy and FEES is described. In addition, videofluoroscopy and FEES are assessed for reliability and inter-instrument agreement.
