Objective:
To study feasibility and indication of cranialbase surgery by transnasal endoscopic approach.
Methods:
Nine cases treated by transnasal were analysed. Those cases included foreign body, olfactory neuroblastoma, meningoma and inverted papilloma in anterior cranial fossa, sinuses sphenoidalis macrosis cyst invading middle cranial fossa, primary cholesteatoma and space occupying lesion in middle cranial fossa.
Result:
The complications were not occurred in all cases. Follow-up survey 1-7 years, no-relapse was occurred.
Conclusion:
It is probability that surgery lesion be close skull base by transnasal endoscopic approach, but indication must be exactitude selected. The operator should be have firm anatomic, skilled operation and richness experience. The malignancy lesion should be compositive treatment after surgery.
