Microscopic rhinoscopy in the treatment of inverted papillomas

Inverted papillomas are endophytic lesions arising from tissues in the nose and paranasal sinuses noted for their local destruction, propensity to recur, and tendency for malignant transformation. It has been well documented that complete removal is essential in the prevention of recurrence; however, use of the operating microscope to ensure this has not been widely described in the past. We present 4 patients, ages 36 to 56, for whom the operating microscope was used intra-operatively and for follow-up examinations. The patients have been followed for 1 to 5 years without any evidence of recurrence to date. We submit that the operating microscope is an extremely valuable tool for the surgical treatment of this lesion in light of the absolute necessity for its complete removal.
