title: [Diagnosis and treatment of sphenoid sinus cyst].
abstract: OBJECTIVE
  To better understand the sphenoid sinus cyst and make correct diagnosis and treat it efficiently.
  
  
  METHODS
  47 patients with sphenoid sinus cyst were investigated. Presenting symptoms, radiographic appearances and treatment were analyzed, respectively.
  
  
  RESULTS
  The present study demonstrated that the incidence of sphenoid sinus cyst had apparently increased in recent years. The most common symptom was headache, accident rate was 64%, followed by ocular disturbance, nose was involved in 15% patients. The optic nerve is the most frequently involved cranial nerve it makes decompression surgery necessary to recovery visual loss. Radiographic finding made contribution to location the lesion and exposition nature of the lesion. With the help of nasal endoscope, more information could be get to establish correct diagnosis, and operation under nasal endoscope would be safe with minimal blood loss, reduced operating time, less pains and short postoperative hospitalization.
  
  
  CONCLUSIONS
  CT, MRI and nasal endoscope provide the greatest diagnosis information and guide management, nasal endoscope plays an important role in treatment of sphenoid sinus cyst. Emergency surgery should be performed on patients with visual loss.
