Endoscopic and Endoscope-Assisted Resections of Inverted Sinonasal Papillomas

Abstract

OBJECTIVE: To evaluate the success of endoscopic and endoscope-assisted resection of inverted sinonasal papillomas and to assess the indications for adjunctive external procedures. STUDY DESIGN: Retrospective chart review. RESULTS: Fifty patients were treated surgically during the 10-year study period and had greater than 1 year of follow-up care. These patients had a recurrence rate of 14% (7/50) with a mean follow-up of 31.1 months. Of these 7 patients with recurrences, 3 were treated primarily at this institution, and 4 had been treated prior to referral. Recurrence was 11% (3/27) for primary resections and 17% (4/23) for secondary resections. Average time to recurrence was 11.7 months. Of the patients, 38% (19/50) had adjunctive external procedures either during the initial resection or for the management of recurrent disease. CONCLUSIONS: Endoscopic and endoscope-assisted resections of inverted papilloma are effective techniques for managing inverted papilloma. The intraoperative findings, most importantly the site(s) of tumor attachment, dictate whether an endoscopic procedure is sufficient to complete resect the inverted papilloma or whether an adjunctive external procedure is required. Appropriate patient selection and an aggressive surgical approach are necessary for the management of these neoplasms.
