“…Typical shunt valves, like the commercially available Groningen Button 19 or Provox valve, 15 have an internal shaft diameter of 5 mm. The length of the shaft is 5-11 mm, depending on the thickness of the tissue wall between the trachea and esophagus.…”

“…1b). 19,20,25 When the tracheostoma is occluded by either a tracheostoma valve or the patients' thumb, exhaled air flows through this valve into the esophagus, where remaining muscular structures and mucosa (the pharyngo-esophageal segment) can be set into vibration. The low-pitched sound that is generated in this way can be used as a substitute voice source for so-called TE speech.…”

Abstract-For voice rehabilitation after total laryngectomy a shunt valve is usually placed in the tracheo-esophageal (TE) wall, thereby enabling the production of a TE voice. Some patients, however, are unable to produce a voice of sufficient quality. Furthermore, the TE voice is low pitched, which presents a problem especially for female laryngectomized patients. The voice quality after laryngectomy might be improved by introducing a voice-producing element (VPE) into the TE shunt valve. In this study a sound generator was developed that is suitable for application in such a VPE. This sound generator consists of two elastic membranes placed parallel inside a circular housing. A substitute voice source is created when the membranes start to vibrate via a constant flow of air passing between them. To determine the optimal membrane configuration for proper functioning under physiological conditions, up-scaled physical VPE models with different membrane geometries were evaluated using in vitro experimental tests. For certain membrane geometries the tests showed that a basic sound, containing multiple harmonics, could be successfully produced under physiological air pressure and airflow conditions. The fundamental frequency (60-95 Hz) and sound pressure level (57-78 dB, at 15 cm microphone distance) were regulated via changes in the driving pressure, thereby enabling the possibility of intonation in laryngectomized patients' speech. The obtained frequency range is considered appropriate for producing a substitute voice source for female patients. The geometry considerations in this study can be used for the development of a true scale VPE that can be evaluated clinically, to eventually replace the voice after laryngectomy.

“…An 'indwelling' version that is only inserted and replaced by a clinician is now available and popular with laryngectomees who can't, or don't want to, accept the responsibility for routine prosthesis manipulation. This 'indwelling' concept originated with the introduction of the Groningen tracheoesophageal voice prosthesis [23]. The Blom-Singer indwelling voice prosthesis is a 20-Fr.…”

“…Based on the experiences with surgical and prosthetic voice rehabilitation (Staffieri's procedure [6] and the Blom-Singer [7], Panje [8], and Groningen [9] prostheses), acquired in our department since 1979 [10], a novel lowresistance, indwelling silicon voice prosthesis. Provox ® , was developed between 1987 and 1990 [11,12].…”

Comprehensive rehabilitation after total laryngectomy is more than voice alone. The removal of the larynx and the subsequent disconnection of the upper and lower airways not only has consequences for the vocal function but also for the respiratory system, and for the olfactory acuity of the patient. The results of the research program on these three subjects in the Netherlands Cancer Institute over the last 12 years are discussed in detail along with some of the relevant other literature on the topics. The considerable progress in these areas over the last 2 decades has clearly improved the quality of life of laryngectomized patients.
