title: [Characteristics of invasive damages of nerve system in sphenoid-sinus-o-tumoropathy and transnasal endoscopic surgery].
abstract: OBJECTIVE
  To explore the relationships between the sphenoid-sinus-o-tumoropathy and local anatomy, as well as the characteristics of invasive damages of nerve system in sphenoid-sinus-o-tumoropathy, and emphasize that it is crucial of early diagnosis and surgery for sphenoid-sinus-o-tumoropathy.
  
  
  METHODS
  Retrospective analysis of the characteristics of invasive damages of nerve system in 13 patients with sphenoid-sinus-o-tumoropathy, and follow-up the outcomes of nerve system after transnasal endoscopic surgery.
  
  
  RESULTS
  1) The majority clinical manifestations of invasive damages in nerve system are cranial nerves, there are 9 cases optic nerve, 7 cases oculomotorius nerve, 4 cases trochlear nerve, 4 cases abducent nerve and 1 cases trigeminal nerve have been found damage at different levels in this group, and the secondly are 3 cases dysfunction of pituitary and 2 cases central nerve damage. 2) The improvement of invasive damages in nerve system after transnasal endoscopic surgery are as follow: at the day of operation or the next day, there are 4 cases to be reported that the symptoms of headache and eyes relieve very well; during 3 to 7 days after operation there are 9 cases to be reported that the symptoms of headache and eyes relieve or disappear significantly; 2 weeks after operation, there are 8 cases to be reported that the optical sights recovery at different levels, and there are many symptoms such as headache (9 cases), visual diplopia (1 cases), ptosis (2 cases), fixation of eyeball (1 cases), exophthalmoptosis (2 cases), face pain (2 cases), orbital paralysis (2 cases) disappeared completely. No complications of cerebrospinal fluid rhinorrhea, brain edema and hemorrhage to be found during the period of operation and follow-up.
  
  
  CONCLUSIONS
  The majority clinical characteristics of invasive damage in nerve system with sphenoid-sinus-o-tumoropathy are cranial nerve manifestations, and the second manifestation is dysfunction of pituitary. Transnasal endoscopic surgery could inhibit the invasive damages in cranial nerves of sphenoid-sinus-o-tumoropathic patients effectively.
