[Inverted papilloma: implications for the oral and maxillofacial surgeon]

7 patients with inverted papillomas of the maxillofacial area were subjected to a post-treatment evaluation. Inverted papillomas were found in maxillary and frontal sinuses, ethmoid cells, nasal septa and as isolated lesions in the mucosa of the mandibular alveolar process. Apart from an inverted papilloma, one patient also had a mucoepidermoid carcinoma. The tendency to recur correlated well with the surgical approach. Radical removal of the mucosa must be called for as primary therapy in the paranasal sinus area. In order to safely exclude a concurrent carcinoma, the entire resected material must be examined histologically.
