INVERTED PAPILLOMA OF THE NOSE AND PARANASAL SINUSES - A STUDY OF 56 CASES AND REVIEW OF THE LITERATURE

Over a period of 32 years, 56 patients with inverted papilloma of the nasal cavity and paranasal sinuses were diagnosed and treated at Beili nson Medical Center, Israel. Four patients (7%) had an associated mali gnancy. Several surgical approaches were used: limited intranasal exci sion in 5 patients with an 80% failure rate, a Caldwell-Luc approach i n 21 patients with a 48% recurrence rate, and lateral rhinotomy with m edial maxillectomy in 18 patients with only a 22% failure rate; a sele cted group of 9 patients underwent an endoscopic procedure, with a 22% recurrence rate. Our results and a review of 19 published reports sug gest that medial maxillectomy via lateral rhinotomy remains the treatm ent of choice for most cases of inverted papilloma. The role of endosc opic excision in selected patients is discussed.
