Abstract:
The inverted papilloma is an uncommon benign tumor constituting 0.5% to 4% of all primary nasal tumors. The tumor is characterized by local aggressiveness, high rate of recurrence and association with malignancy. Intracranial extension or encroachment without associated malignancy is very rare. The treatment should be en bloc resection to prevent the recurrence. Recently, the authors have experienced a case of large inverted papilloma of the nasal cavity invading the anterior cranial base without associated malignancy. The tumor was removed en bloc by craniofacial resection combined with medial maxillectomy through lateral rhinotomy approach. The defect of the skull base was repaired with pericranial flap and temporal muscle flap. The patient has been followed for 2 years and has showed no recurrence.
