Sinonasal Manifestations in Children with Cystic Fibrosis

Background: Involvement of the upper respiratory tract and pathological changes in the nose and paranasal sinuses are common in patients with cystic fibrosis. Objectives: We aimed to identify sinonasal manifestations in Iranian children with cystic fibrosis. Methods: Forthy seven children with cystic fibrosis were enrolled and symptoms related to the nose and paranasal sinuses were recorded using a questionnaire. The patients' nasal and sinus CT scan were investigated in terms of findings related to cystic fibrosis. Results: The most common complaint was nasal congestion (61.7%). Ground glass opacity in the nasal cavity was found in 63.8% of the patients. Postnasal drip was observed in 36.2% of the patients. In nasal endoscopic examination, 15 (31.9%) patients had clear polyps in the nasal cavity. Conclusions: History, CT scans, and initial clinical examination (rhinorrhea in anterior rhinoscopy) does not allow accurate diagnosis of chronic rhino sinusitis or nasal polyps in children with cystic fibrosis.
