title: [The treatment of sinusitis in patients with nasopharyngeal carcinoma after radiotherapy and the relative factors].
abstract: OBJECTIVE
  To explore the surgery way on sinusitis with nasopharyngeal carcinoma (NPC) caused by radiotherapy and the relative factors.
  
  
  METHODS
  Forty-five cases of NPC patients with sinusitis caused by radiotherapy were treated by endoscopic sinus surgery in our department from 1998 to 2003. There were 24 males and 21 females, ranging in age from 34 to 45 years old. The clinical data of the patients were analysed retrospectively.
  
  
  RESULTS
  All the patients were followed up for a period of 1 to 4 years after operation. 22 cases (48.9%) were cured, 18 cases (40%) were improved, but the other 5 cases (11.1%) were no effective. No serious complications and tumor recurrence occurred.
  
  
  CONCLUSIONS
  The incidence of sinusitis in patients with NPC after radiotherapy is very high which interferes the effect of radiotherapy on NPC. Endoscopic sinus surgery is an effective method to open sinus ostium. It is feasible and favorable.
