Abstract

Background: Nasal septum deviation (NSD) is a common anatomical variation that can impair nasal airflow and is associated with various nasal-sinus disorders. Coexisting anatomical variations, including concha bullosa and inferior turbinate hypertrophy, may exacerbate nasal obstruction and reduce the effectiveness of medical and surgical interventions. This study aimed to evaluate the morphological characteristics of nasal septum deviation and associated nasal-sinus anatomical variations on computed tomography imaging. Methods: A cross-sectional descriptive study was conducted on 102 who underwent CT scans of the paranasal sinuses at Nhan Dan Gia Dinh Hospital from September 2024 to May 2025. NSD was classified according to Mladina’s system. The deviation angle was measured and categorized into three groups (<5°, 6–10°, 11–15°). Associated anatomical variations such as concha bullosa and inferior turbinate hypertrophy were also assessed. Results: 61 patients (59.8%) had NSD, with a mean age of 44 years. Type I deviation was the most common (32.8%), followed by Type III (31.1%). Group II deviation angle (6–10°) was the most frequent (41.3%). Associated anatomical variations were observed in 27% of cases. Conclusion: Nasal septum deviation and associated anatomical variations are highly prevalent on CT imaging. Systematic preoperative evaluation of these features can assist surgeons in optimizing surgical planning and improving treatment outcomes.
