Surgical voice rehabilitation after laryngopharyngectomy. Functional results of tracheo-hypopharyngeal shunts by jejunal transplantation.

For surgical voice rehabilitation after pharyngolaryngectomy we use the technique of placing a siphonlike jejunal interposition in order to create a tracheohypopharyngeal shunt. In this paper we present the functional benefits of this method of voice rehabilitation. The best results achieved are compared with a normal voice using the following test parameters: electroacoustic sound analyses and voice status. The findings show that the siphon voice is adequate for everyday purposes and can achieve useful social verbal communication.
