title: [Endoscopic sinus surgery, clinical observation with 40 cases].
abstract: OBJECTIVE
  To study the curative effect of endoscopic sinus surgery(ESS).
  
  
  METHODS
  The clinical data of ESS on 40 cases(70 sides) of chronic sinusitis and nasal polyps were analyzed.
  
  
  RESULTS
  In 34 of the 40 cases followed up over six months, 25 cases(73.5%) were cured, 7 cases(20.6%) were improved, 2 cases(5.9%) were ineffective. The effective rate was 94.1%. The serious operation complication was absent. Bleeding after operation was found in 1 case, middle turbinate synechiae with nasal septum were found in 2 cases.
  
  
  CONCLUSIONS
  ESS is effective in the treatment of chronic sinusitis and nasal polyps. The success of operation is directly related to the excellent surgical skills. A regularly follow up and cleaning to the operation cavity after operation are important elements for securing optimal long-term result.
