[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.

[Neoplastic tumors in patients with unilateral inflammations qualified for endoscopic surgery]

INTRODUCTION

The aim of this work was to analyze the occurrence and type of neoplasm in unilateral pathological lesions within the nose and paranasal sinuses in patients who underwent endoscopic surgery, in own material.

MATERIAL AND METHODS

Between 2006 and 2012 2295 patients, including 1006 women aged 15-84 and 1289 men aged 17-87, were operated on due to diseases of paranasal sinuses in the Department of Otolaryngology and Laryngological Oncology. The patients underwent surgery after a medical interview, physical examination, 3D CT of paranasal sinuses and laboratory tests. The removed lesions were histopathologically investigated. The studied group included the patients with only unilateral lesions and histopathologically recognized neoplastic lesion.

RESULTS

In the studied material, neoplastic lesions occurred in 9.8% cases, out of which 5.4% were inverted papillomas, 3.1% osteomas, and 1.5% malignant tumors. However, in the patients who were operated due to hypertrophic changes within paranasal sinuses, neoplasm was found in 1.3% cases, while inverted papilloma in 0.7%, osteoma in 0.4% and malignant tumors in 0.1%, which altogether amounts to 8 times higher occurrence of neoplastic lesions in unilateral changes.

RESULTS

Unilateral changes within paranasal sinuses require highly inquisitive pre-operative diagnostics, peri-operative analysis and histopathological evaluation.

Unilateral pathological lesions of paranasal sinuses removed by endoscopic surgery

INTRODUCTION

The aim of this study was to analyze the incidence and nature of unilateral pathological lesions of paranasal sinuses in patients who had endoscopic sinus surgery performed in ENT.

MATERIALS AND METHODS

In the years 2006-2011 endoscopic sinus surgery for unilateral pathological lesions of paranasal sinuses was performed in 1847 patients (838 women and 1009 men). The enrollment of patients was based on the findings of otolaryngological clinical and subjective examinations, assessment of the paranasal sinuses on three-dimensional CT scans, and laboratory examinations. Based on the analysis of medical history data, including gender, age, the type of surgical procedure performed, and histopathological findings the cases were finally analyzed.

RESULTS

Pathological lesions of the paranasal sinuses were localized on the left side in 132 (57%) patients, and on the right side in 100 (43%) patients. Of the 232 patients with unilateral pathological changes, 41.8% subjects underwent endoscopic sinus surgery for polypotic changes in the ethmoid and maxillary sinuses; 28.4% for the maxillary sinus; 10.8% for the ethmoid, maxillary and frontal sinuses; and 8.6% patients for all paranasal sinuses on one side. The number of operations of only one sinus was considerably lower: sphenoid sinus, 4.7%; ethmoid sinus, 2.2%; and frontal sinus, 1.7% patients. The histopathological analysis of unilateral pathological lesions removed by endoscopic surgery showed chronic paranasal sinusitis with polyps in 56.5% patients; chronic paranasal sinusitis in 22.8% patients; and maxillary sinus cyst was confirmed in 11.6% patients. In 5.1% patients inverted papilloma was diagnosed and in 2.2% patients the presence of osteoma was found.

CONCLUSIONS

Unilateral paranasal pathological lesions, leaving aside rather typical maxillary sinus cysts, require a particularly thorough pre-operative diagnosis and a precise histopathological assessment.
