[Rehabilitation in esophageal speech and its perceptive-acoustic features after total laryngectomy without pharyngo-esophageal plastic surgery]

Abstract

The experiences with the plastic surgery of pharyngo-oesophageal sphincter during the laryngectomy were presented. The sphincteric forces were studied accordingly to the rehabilitation successes and also the acoustic and perceptive data of the oesophageal speech. The results were compared with these after the classical laryngestomy. It was pointed out that the sphincteroplasty lowered its tension and made the rehabilitation more easier. The oesophageal voice produced in this occasion is better than after the classical laryngectomy. The fundamental frequency is two times higher, the prosody and speech tempo more normal. These positive results were encountered in 76% of cases. However, in some cases the psychological and social difficulties were so great that we preferred the surgical rehabilitation with shunt formation.
