Objective:
To study the treatment of inverted papilloma (NIP) with intracranial extension.
Method:
Nine patients of NIP all suffered from the operation. Six patients with anterior skull base erosion suffered from large tumor resections via combined craniofacial and cranial approach. Three patients suffered from small tumor resections via transfrontal and transethmoidal sinus approach. The defects of basicranial bone and dura were repaired at the same time. Five patients were found the tissue canceration in the postoperation.
Result:
In 7 patients followed-up from 3 to 13 years, no one has recurrenced.
Conclusion:
The canceration probability of NIP with intracranial extension should be sufficiently considered. The tumor resection via combined craniofacial approach or transfrontal approach must be based on the tumor size and extension, and removed completely.
