OBJECTIVES To assess the use of indwelling tracheoesophageal speaking valves in Chinese patients undergoing laryngectomy, to identify the clinicopathologic factors for favorable outcome, and to evaluate the factors that determine prosthesis lifetime. DESIGN Retrospective review. SETTING Tertiary care institution. PATIENTS Sixty consecutive patients with total laryngectomy were included. A...

INTRODUCTION In properly selected patients, the use of a voice prosthesis placed in a surgically created tracheoesophageal fistula (TEF) is a successful and desirable method of postlaryngectomy vocal rehabilitation. The long-term success rate for tracheoesophageal speech is high, ranging from 70% to 95%. Unfortunately, some patients develop complications that include: migration and progressive ...

INTRODUCTION Prosthetic voice restoration has been widely used for vocal rehabilitation in laryngectomised patients. The objectives of this study were to examine success rates, predictors of success and complications for our patients who had undergone tracheoesophageal punctures (TEPs) and voice prosthesis placement after laryngectomy. To our knowledge, this is the first analysis of the use and...

BACKGROUND The objective of the present study was to relate the dimensions and the intraluminal pressure of the pharyngoesophageal segment (PES) to the voice and speech proficiency of total laryngectomees with a tracheoesophageal prosthesis (TEP). METHODS Twenty total laryngectomees with secondary TEP insertion underwent evaluation of voice and speech, manometry, and videofluoroscopy. RESUL...

After total laryngectomy the normal voice can be replaced by an electronic artificial larynx (AL). However, the results of the surrogate voice are not overall satisfying due to a robotic clattered sound of that prosthesis. In this paper the outcome of a sound investigation for an AL is presented. This work is part of our AL research project on laryngectomee speech enhancement. As a result, an a...

BACKGROUND Pharyngoesophageal spasm is a known entity to cause hypertonic/failed tracheoesophageal speech and is successfully treated by botulinum toxin A injection. However, success of botulinum toxin treatment is based on the accurate localization of the pharyngoesophageal segment. METHODS A 65-year-old man who had a laryngectomy using voice prosthesis with hypertonic speech underwent ultra...
