Abstract
Since 1992, 42 patients at the University of Pennsylvania have been treated for inverted papilloma (IP). Thirty-three patients were managed endoscopically with or without a Caldwell Luc approach (CLA) and retrospectively analyzed. The CLA, which involves a gingivobuccal incision for access to the maxillary sinus, is distinguished from a formal Caldwell Luc procedure. These 33 patients with histologically confirmed IP were without evidence of malignancy. They also did not have evidence of intracranial, orbital, or frontal sinus IP. Seventeen of 33 patients (17/33) were without prior treatment (primary). Sixteen of 33 (16/33) presented from an outside institution with recurrent IP (secondary). The recurrence rate using this method to treat primary IP was 6% (1/17), and for secondary IP was 25% (4/16). Scheduled postoperative endoscopic surveillance permitted early detection of recurrence and continued endoscopic control of IP. All 33 patients were endoscopically free of disease at the end of the study. These preliminary data are encouraging for the use of intranasal endoscopy with and without CLA as a means of managing and controlling IP in selected cases.
