Inverting papillomas of the nose and paranasal sinuses

Inverting papilloma of the nose and paranasal sinuses can sometimes be very difficult to distinguish from other nasal tumors, and the confusion ranges from allergic nasal polyposis to carcinoma. They are also certainly characterized by multiple recurrence, particularly after limited operations. The experience with 34 cases seen at UCLA over the past two decades is analyzed and a philosophy of treatment is outlined. We favor wide local excision which generally necessitates a lateral rhinotomy and medial maxillectomy. The operative approach will be described in detail.
