title: [Diagnosis and treatment of nasal sinus mucoceles invaded the skull base and orbit].
abstract: OBJECTIVE
  To review the clinical manifestations and management of nasal sinus mucoceles invaded the skull base and orbit.
  
  
  METHODS
  Medical records for 30 patients of paranasal sinus mucoceles invaded the skull base and orbit were reviewed retrospectively. CT and MRI were important tools for diagnosing nasal sinus mucocele. The patients received endoscopic surgery to remove mucocele, some of them were operated auxiliary incision. Steroid therapies were given after the operations and routine examination with endoscopy were carried out during follow-up.
  
  
  RESULTS
  All cases were successfully performed surgery without complications after the surgeries, or the majority of symptoms. However, vision recovery was observed only in some patients. Recovery of vision depended on the timing of surgery and severity of initial visual loss. Delay treatment can seriously compromise the recovery of vision impairment. Moreover, the patients without light perception before surgery had poor visual recovery even when optic nerve decompressions were performed.
  
  
  CONCLUSIONS
  Endoscopic surgery has effect on nasal sinus mucocele with visual loss. Because visual recovery depends on prompt diagnosis and surgical intervention,a good understanding of the disease and prompt imaging studies are important.
