[Paranasal sinuses CT scans analysis of patients with cystic fibrosis].

Thirty patients with cystic fibrosis (CF) were diagnosed of the otolaryngological outpatient clinic, a part of Department of Otorhinolaryngology Medical Academy in Warsaw, in 1996-1998. The control group was formed by thirty patients with chronic rhinosinusitis (CRS). Computed tomography (CT) scans were estimated in all cases. Results showed, that inflammatory changes are more advanced in patients with cystic fibrosis than in patients with chronic rhinosinusitis. The high progression of inflammatory changes in patients with cystic fibrosis, observed in CT scans, caused: disturbed development of a frontal and maxillary sinuses, destruction of bony structures formed the lateral wall of the nasal cavity, medical bulging of the lateral nasal wall.
