title: [Isolated sphenoid sinus disease].
abstract: OBJECTIVE
  The purpose of this study is to review isolated sphenoid sinus disease, to establish correct diagnosis and to treat it effectively in the future.
  
  
  METHODS
  26 patients underwent endoscopic surgery, in which 20 sphenoid sinus mucocoeles were removed and 6 sphenoid sinuses were explored. 3 sphenoid sinus mucocoeles were removed by external approach, 1 patient underwent skull base surgery and decompression of optic nerve.
  
  
  RESULTS
  24 patients were free from disease postoperatively within 0.5-4 years follow-up, 2 patients underwent re-operation because of recurrence, 1 patient was undergoing radiotherapy, 3 patients could not contact.
  
  
  CONCLUSIONS
  This study shows that CT not only makes contribution to establish correct diagnosis but also plays an important role in surgery of isolated sphenoid sinus disease. Endoscopic surgery is valuable in treatment for benign disease of sphenoid sinus.
