Your doctor can diagnose an inverted papilloma by inserting a flexible tube called an endoscope into your nose. He or she will then take a sample of the tumor to confirm the diagnosis and determine whether it’s cancerous. You may also have a CT or MRI scan to determine the extent of the tumor.
Inverted papillomas are resected by an otolaryngologist through a minimally invasive approach called Functional Endoscopic Sinus Surgery (FESS). More advanced tumors can require a combined approach between neurosurgery and otolaryngology called the Expanded Endonasal Approach (EEA). In both approaches, there are no skin incisions and the recovery is more rapid than with open approaches.
