Microendoscopic endonasal approach in treating diseases of nasal cavity, paranasal sinuses, and adjacent structures--a preliminary communication.

Since the beginning of 1997 the authors has introduced routinely in their practice a method of combined nasal endoscopy and microrhinoscopy in the diagnosis and minimally invasive surgery of diseases of nasal cavity, paranasal sinuses, and adjacent structures. The results of the method applied in 25 patients (19 males and 6 females) aging from 2 months to 77 years with doubtful initial diagnosis are analysed. In 17 of the patients the initial diagnosis was confirmed, in 5 the diagnosis was revised, and in 3 no pathology of the nasal cavity and paranasal sinuses was found. In 13 patients minimally invasive surgery was successfully performed using this modern method. The results obtained are compared to the related literature data.
