Inverted Papilloma

Inverted papilloma represents the most common benign tumor of the sinuses. Despite its benign nature, tumors can be locally aggressive and recur with inadequate surgery. About 10 percent of them can also harbor cancer, specifically squamous cell carcinoma.

The tumor is most commonly seen in middle-aged men. Its signs include nasal blockage, facial pressure, drainage, and occasionally bleeding. The tumor occurs most commonly in the maxillary and ethmoid sinuses, located beside and above the nose. 

Endoscopic evaluation is important to help with your diagnosis. Typically, these tumors have a “warts in the nose” appearance on endoscopy. A CT scan is critical to define the extent of the tumor. Your physician may need an MRI in some extensive cases of inverted papilloma.

Treatment Options

Endoscopic techniques have been very successful in removing these tumors. Doctors perform this procedure with rigid telescopes to visualize the tumor, avoiding any external facial scars. Endoscopy allows the surgeon to precisely identify tumor origin and boundaries to achieve complete tumor resection. This usually has low risk and a high success rate (90 percent for many cases).

Long-term follow-up is essential as the tumor can recur despite successful surgery.

UT Southwestern Medical Center’s neurosurgeons are highly trained and experienced in endoscopic techniques for removing these tumors.
