Modular Prosthesis of the Larynx: Visions and feasibility
EasyChair Preprints, 2018Co-Authors: Fridun Nazaradeh, Claus Eckermann, Wiebke Kelterer, Siegfried Steltenkamp, Marc André DupréAbstract:Purpose: A total laryngectomy, usually performed after the diagnosis of a laryngeal carcinoma of the stages T3 or T4 in cases where a radiation therapy is not indicated, still leads to radical restrictions of the patient. The postoperative consequences include the loss of the voice, the loss of the regular air ways via mouth and nose, thus also leading to the loss of the sense of smell, and the inability to build up an abdominal pressure. The feasibility of a Larynx Prosthesis which enables the laryngectomee to talk with his or her usual voice, to breathe via the regular air ways, and to build up abdominal pressure is discussed here.Materials and methods: The autonomous Prosthesis consists of a device to reproduce the natural human voice, a device to reproduce the natural air ways including an artificial epiglottis to avoid choking, and a system of valves to build up an abdominal pressure e.g. to cough. The Prosthesis consists of two modules: a stationary module and an exchangeable module. This is necessary to avoid a destruction of the electronics during possible radiation therapies and to easily replace components in case of a breakdown.Conclusions: Regarding the present possibilities of rehabilitation the modular Prosthesis of the Larynx for use in patients after laryngectomy means a medical and ethical benefit for the postoperative course in rehabilitation of laryngectomees.

Advantages of voice reproduction and the development of a biomimetic self-regulating double-clack valve for a Prosthesis of the Larynx - a feasibility study
2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012Co-Authors: Fridun Nazaradeh, Denis Nazaradeh, Marc André Dupré, Claus Eckermann, Wiebke Kelterer, Thomas Doerge, Siegfried SteltenkampAbstract:The human Larynx is a versatile organ. Main functions are phonation, protection and regulation of the air ways. Patients suffer severely from the diagnosis of a laryngeal carcinoma of the stages T3 and T4. In most cases this diagnosis will lead to a total laryngectomy, which is usually dissatisfying in the sense of postoperative rehabilitation. The postoperative consequences include the loss of the native voice, the loss of regular air ways via mouth and nose, sense of smell, and the inability to build up an abdominal pressure. In this paper we focus on the feasibility of a modular Larynx Prosthesis which enables the laryngectomee to talk with his native voice, to breathe via the regular air ways, and to build up abdominal pressure. In particular we will give insights for a postoperative solution - a modular Prosthesis based on a biomimetic self-regulating double clack-valve and on a voice reconstruction module, a so called vocoder. The vocoder is a device to reproduce the natural human voice. Most important for the use is an additional device required to analyze, conserve and manage voice characteristics of the patient before surgery. The self-regulating double clack-valve is designed to build up an abdominal pressure e.g. to cough. Therefore, our valve-system is working in both directions - a two-way valve system. By bridging the gap of the regular air ways lost by laryngectomy, the sense of smell and taste are restored. In the following we will present details and characteristics of these two main components required for a modular Prosthesis of the Larynx in laryngectomees.
