Background: The nasal cavity is a vital structure for respiration, olfaction, and phonation. Anatomical differences are common, driven by genetic and environmental factors. These variations include septal deviations, turbinate hypertrophy, and accessory air cells. Such differences can alter airflow, mucociliary function, and disease susceptibility. Computed tomography (CT) is crucial for evaluating these differences. Assessing nasal cavity anatomy is essential for pre-surgical planning and managing sinonasal diseases. This study aimed to determine the prevalence and clinical significance of nasal cavity anatomical variations using CT scans. Method: This descriptive cross-sectional retrospective study was conducted at RSUTH, Nigeria. Ethical approval was obtained. The study analyzed 339 adult, non-contrast CT scans using RadiAnt Dicom software. Images were evaluated for the different anatomical patterns associated with the nasal cavity. Poor quality images and images of were excluded. Results: The most prevalent nasal cavity pattern was nasal septal deviation (68%), whereas the least prevalent was septal spur with choncha bullosa (2.4%). Other variants seen were agger cells more in the left nasal cavity of males and also haller cells were predominantly seen in the left nasal cavity of females. Conclusion: Knowledge of nasal cavity anatomical variations is crucial for ENT surgeons to ensure safe and efficient surgical procedures. Pre-operative evaluation of the nasal septum is essential for surgical planning, reconstruction, and optimal cosmetic outcomes.
