title: [Pharyagoesophageal sphinoter myotomy for voice rehabilitation after total laryngectomy].
abstract: OBJECTIVE
  In those patients received total laryngectomy, Blom-Singer prosthesis speech appears to be the more effective form of rehabilitation. To reduce the effect of pharyngoesophageal sphincter on the Blom-Singer prosthesis voice restoration following total laryngectomy, the pharyagoesphageal sphincter myotomy was designed and carried out.
  
  
  METHODS
  After total laryngectomy, the cricopharyngeus muscle stricture or spasm appears to inhibit the air flowing and prevent the speech. The pharyngoesophageal sphincter is now defined as the area including the cricopharyngeus with a portion of inferior constrictor, as well as some of the upper cervical esophagus. The pharyngoesophageal sphincter were incised intra- and post- operation of total laryngectomy, the dissection was approximately 5 cm in vertical length and 1 cm in width.
  
  
  RESULTS
  Among the 33 patients who received pharyngoesophageal sphincter myotomy following total laryngectomy, voice restoration was achieved in 32 cases, the success rate was 97%. 25 patients had survived for 3 years, 18 patients survived for 5 years.
  
  
  CONCLUSIONS
  Pharyagoesophageal sphincter myotomy can raise the success rate of rehabilitation of the voice by Blom-Singer prosthesis.
