Papilloma of the nasal cavity and paranasal sinuses is histologically a benign neoplasm, but it exhibits a high recurrence rate, and an association with malignancy. Therefore, nasal and paranasal papilloma must be thoroughly treated. The authors treated 11 patients with papilloma, 10 of them with the Caldwell-Luc approach. One case of papilloma showed a malignant change to a verrucous carcinoma during the following up period. The recurrence rate of papilloma was 9%, following surgical treatment.
