title: [Pharyngeal plexus neurectomy for voice restoration of alaryngeal].
abstract: OBJECTIVE
  To release the spasm of pharyngeal constrictor and raise the successful rate of voice rehabilitation in total laryngectomized patients wearing Blom-Singer prosthesis.
  
  
  METHODS
  The main branch of the pharyngeal plexus nerves within the inferior contractor can be found at the posterior side of hyoid greater cornu, which is about 6.5 mm from the back of constrictor. The spasm of the inferior constrictor can be resolved by cut off the nerve.
  
  
  RESULTS
  Voice restoration was achieved in 15 cases after pharyngeal plexus neurectomy, the successful rate was 93.75%.
  
  
  CONCLUSIONS
  It is feasible to replace pharyngeal myotomy by nerve plexus neurectomy and raise the voice rehabilitation rate.
