Computerized tomography scan evaluation of nasal abnormalities including nasal septal deviation angle and turbinate hypertrophy in patients referred for rhinoplasty

Background: The nasal septum is an important physiological and support structure of the nose. Nasal Septal deviation is the most commonly seen deformity of the nose. It is considered to be congenial or trauma- sustained at any time in the life. Aim of study: To assess the severity of nasal septal deviation angle, size and shape of deviation; it’s relation with normal variant. Patients and methods: Cross- sectional CT scan study conducted in the CT Radiology Department of the X-ray institute in Baghdad Medical City Compass, on patients referred for rhinoplasty. Results: About 48 patients had nasal septum deviation to the left side, 30 patients had nasal septal deviation to the right side, and 22 patients had normal septum. 49 patients had type II nasal septal deviation angle. Conclusion: Many patients referred for cosmetic rhinoplasty who’s age less than 30 years or patients with nasal obstruction whose age above 30 show nasal septal deviation that required septorhinoplasty.
