Praktische Aspekte der prothetischen Stimmrehabilitation nach Laryngektomie

Abstract

Since the last decade of the last century, surgical voice restoration with the use of voice prostheses has become a standard after total laryngectomy. About 80-90 % of the patients are capable to speak well or even very well with a voice prosthesis. Although severe complications have become rare since special pharynx protectors are in use for the implantation of the voice prostheses, minor problems are quite common. Primarily, these are frequent leakages through the prosthesis caused by fast wear and tear of the material and biofilms on the surface of the prosthesis, granulation tissue around the prosthesis, loss of the prosthesis with either aspiration or ingestion and migration or enlargement of the fistula. This paper explains the application of the most common kinds of voice prostheses and the management of the most frequent problems.

Tracheostomy cannulas and voice prosthesis

“…Moricz et al refer to endoscopy-based balloon dilation as a non-traumatic method that can be easily performed [166]. Delank and Scheuermann recommend manufacturing an individually adjusted Herrmann voice prosthesis in order to bypass the spastic or stenotic pharyngoesophageal area [167]. …”

Precision Antifungal Treatment Significantly Extends Voice Prosthesis Lifespan in Patients Following Total Laryngectomy

“…A loss of valve functionality leads to poor speech and requires replacement of the device (Ticac et al, 2010;Leonhard and Schneider-Stickler, 2015). Moreover, the microbial colonization may act as a reservoir of potential pathogens which, subsequent to aspiration, may lead to life-threatening infections such as pneumonia (Delank and Scheuermann, 2008). The mean VP lifespan is highly variable across different studies and has historically been reported as being between 120 and 200 days (Schafer et al, 2001;Sayed et al, 2012).…”
