The first aim of this study is the compilation of the various methods of voice and speech rehabilitation following laryngectomy. Therefore, this book gives a detailed survey of these voice rehabilitation methods, with emphasis on the tracheo-esophageal shunt method with a valve prosthesis in respectively Chapter II, Chapter III and Chapter IV. The development of these valve prostheses, which are inserted into a surgically created tracheo-esophageal shunt, has presented a giant step forwards in the voice and speech rehabilitation of laryngectomees.
Speech produced by trapping air in the esophagus and forcing it out again. It is used after removal of a person's larynx (voice box).
The total laryngectomy is a standard procedure of laryngeal carcinoma treatment which leaves multiple persistent consequences on a laryngectomized person. After laryngectomy, all of patients cannot speak loudly, and 10–58% patients have a dysphagia. In such changed anatomical condition, the esophagus has a key function in two of three primary approaches to voice—speech rehabilitation of laryngectomized patients: esophageal and tracheoesophageal speech therapy method because one of these is the only acceptable solution of substitute alaryngeal speech.
