چکیده
UNLABELLED In tracheo esophageal puncture (TEP), we carry out a myotomy of the pharynx constrictor muscle; however, about 9 to 79% of patients need such procedure. The consequence of such procedure is an increase in salivary fistula rates in the postoperative. Botulin toxin is used in an outpatient basis. AIM analyzing the efficacy of botulin toxin (BT) use in the rehabilitation of totally laryngectomized patients with tracheo-esophageal voice (TEV) with spasms (S) of the pharyngo-esophageal segment (PES) without myotomy. MATERIALS AND METHODS We analyzed eight patients submitted to total laryngectomy (TL), rehabilitated with TEV, with speech prosthesis (SP) and struggle to utter voice because of PES spasms. They were all submitted to treatment of such motor alteration with the injection of 100 units of BT in the PES. The evaluation was based on perceptive voice analysis, video fluoroscopy (VF) of the PES, acoustic voice analysis and computerized manometry (CM) of the PES, all before and after BT injection. STUDY DESIGN prospective. RESULTS There was a reduction in PES CM pressure after BT injection. Acoustic analysis showed an improvement in harmonics quality after treatment. There was smoother voice utterance and spasm improvement after BT. CONCLUSION all patients with PES spasms presented vocal improvement after BT injection in the PES.

UNLABELLED Tracheoesophageal voice (TEV) with voice prosthesis (VP) is an efficient and reproducible method used in vocal rehabilitation after total laryngectomy (TL), prevented by spasms in the pharyngoesophageal segment (PES). Computerized Manometry (CM) is a new, direct and objective method used to assess the PES. AIM to carry out an objective analysis of the PES, with CM, before and after...

BACKGROUND Pharyngoesophageal spasm is a known entity to cause hypertonic/failed tracheoesophageal speech and is successfully treated by botulinum toxin A injection. However, success of botulinum toxin treatment is based on the accurate localization of the pharyngoesophageal segment. METHODS A 65-year-old man who had a laryngectomy using voice prosthesis with hypertonic speech underwent ultra...
