Detailed Description

Choanal atresia is a rare congenital disorder caused by a failure to develop the posterior nasal cavity (choana), resulting in a missing opening between the nasopharynx and the nasal cavities.It is the most common congenital anatomical abnormality of the nasal cavities with incidence ratio approximately 1/5000-7000 live births

Generally, choanal atresia may affect one or both Choanae, although most studies show that the unilateral form is more common than the bilateral one,and the incidence is higher in females than in males Children with unilateral choanal atresia are subject to unilateral breathing usually have late unilateral nasal obstruction, persistent ipsilateral rhinorrhea, and recurrent rhinosiusitis Previous studies have shown that the ratio of bone to membranous atresia is 9:1; although a detailed review of CT findings with histopathological studies showed that mixed-wall atresia is the most common and is present in 71% of cases, while in 29% of cases we found a pure bone wall Computer tomography (CT) is presently the golden standard in diagnostics of nasal cavity diseases; thus, it can be applied successfully as a tool for assessing anatomical structures

Outcome Measure
Measure Description
Time Frame
Radiological Variations in Skull Bones in Patients with Congenital Unilateral Choanal Atresia: A Cross-Sectional Study"
Time Frame: 10_12 month

Degree and Type of Skull Bone Anomalies Presence and extent of bony abnormalities in the skull base (e.g., sphenoid bone asymmetry, pterygoid plate thickening) Degree of nasal cavity narrowing and choanal obstruction Associated maxillofacial bone abnormalities (e.g., septal deviation, maxillary sinus hypoplasia)
