title: [Neoplastic tumors in patients with unilateral inflammations qualified for endoscopic surgery].
abstract: BACKGROUND
  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.
  
  
  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.
