RESUMO
<p><b>OBJECTIVE</b>To evaluate rehabilitation effect of Amatsu's tracheoesophageal shunt operation after total laryngectomy with sphincter mechanism.</p><p><b>METHODS</b>Voice rehabilitation were performed for 60 cases with Amatsu's tracheoesophageal shunt operation after total laryngectomy with sphincter mechanism, in which 20 cases were involved in post-operation radiation therapy.</p><p><b>RESULTS</b>Fifty two (86.7%)cases developed speech with voice and swallow rehabilitation, but 1 case of them suffered water drip from his tracheoesophageal shunt when drinking. The other 8 (11.3%) cases developed swallow rehabilitation but failed in speech rehabilitation for pharyngeal fistula (4 cases, in which 1 had pre-operative radiation therapy), tracheoesophageal shunt obstruction (2 cases), dyspnea with unknown reason (1 cases), no desire to speech (1 cases). Furthermore, all the 20 cases who were involved in post-operative radiative therapy restore their speech and swallow capability finally.</p><p><b>CONCLUSIONS</b>Amatsu's tracheoesophageal shunt operation with sphincter mechanism brought effective speech rehabilitation results for total laryngectomy even with post-operation radiation therapy.</p>
