title: [Semiconductor laser use in endoscopic transnasal dacryocystorhinostomy].
abstract: OBJECTIVE
  To explore the using and value of semiconductor laser in endoscopic transnasal dacryocystorhinostomy.
  
  
  METHODS
  In 8 cases with obstruction of nasolacrimal duct, after being had submucous resection of nasal septum, nasal polypectomy or sinus resection, we used the fiberoptic light probe through the canalis nasolacrimalis to confirmed the location of sacculus lacrimalis and resected the mucosa and bone on lateral wall of nasal cavity that covering the sacculus lacrimalis.
  
  
  RESULTS
  Six months after operation, the mucous was complete epithelization and ostium without stricture in seven cases. One case was covered with ulo, after reexcised with semiconductor laser and put the silicon through the canalis nasolacrimalis, the ostium without stricture in 6 months.
  
  
  CONCLUSIONS
  Semiconductor laser can obviously reduce bleeding,adhesion and granulation tissue,it is a good, simply and shortcut way for clinic.
