[Analysis of histopathological evaluation of pathological lesions removed by endoscopic surgery of the nose and paranasal sinuses in the own material].

The work aimed at evaluating results of histopathological examination of postoperative material in endoscopic paranasal sinus surgery in the own material.
The analysis covered 3,896 results of histopathological examination of routine postoperative material from the Department of Clinical Pathomorphology and Cytopathology Military Medical Academy University Clinical Hospital in Lodz. The study was conducted in hematoxylin and eosin staining according to the principles of this method. The postoperative material included pathological lesions removed by endoscopic surgery of the nose and paranasal sinuses in patients who were treated at Department of Otolaryngology and Laryngological Oncology between 2006 and 2010. The treatment included 1,118 patients, 509 women at the age of 15–79 and 609 men aged 17–77. The material for histopathological examination was sent from merely 1,176 operations because 57 patients were operated twice and one patient was operated three times.
Polyps within the nose and paranasal sinuses were confirmed by histopathological examination in 705 patients, including 289 women and 416 men. Hypertrophic changes were diagnosed in 404 patients, including 218 women and 186 men. Inverted papilloma was recognised in histopathological examination in 9 patients, including 2 women and 7 men. Hypertrophies were slightly more common in women than in men. Both in men and women unilateral hypertrophic changes within the ostiomeatal complex were predominant, 42.66% in women and 40.86% in men.
Histopathological examination of postoperative material in patients under endoscopic treatment due to paranasal sinusitis is considerably important for complex evaluation of inflammation type and confirmation of indications for appropriate anti-inflammatory therapy.
