[Inverted papilloma of the nose and paranasal sinuses in own material].

INTRODUCTION

The aim of this work was to analyze the occurrence of inverted papilloma within the nose and paranasal sinuses, the extent of lesions and the clinical course in the patients who underwent endoscopic surgery.

MATERIALS AND

METHODS

Between the years of 2006-2012, at the Department of Otolaryngology and Laryngological Oncology, 2295 patients were subjected to surgery due to paranasal sinus diseases. The material was based on their past medical histories. The analysis includes the age and gender of the patients, the type of surgery, and results of histopathological examinations. A surgical procedure covered the paranasal sinuses with lesions diagnosed in CT. The qualified patients had inverted papilloma in histopathological results.

RESULTS

Among 2295 patients who were operated because of chronic inflammatory changes, inverted papilloma was histopathologically diagnosed in 49 cases. In 16 patients with inverted papilloma, inflammatory changes were present on one side only, while in 33 cases inverted papilloma was confirmed histopathologically on one side. The analysis of age and gender of the study group showed that the highest occurrence of inverted papilloma was in patients over 50 years of age. In the majority of the studied cases, inverted papilloma spread in the middle nasal concha and the maxillary or ethmoid sinus.

CONCLUSIONS

In surgery, the endoscopic technique allows for an effective removal of inverted papilloma from the nose and paranasal sinuses. According to the authors, endoscopy is the most valuable method for post-operative monitoring of recurrent inverted papilloma.
