<p>Anthropometric assessment of nose yields information regarding its shape and dimensions. The shape and symmetry of nostrils and alar base are critical factors in determining the overall appearance of nose. This study aimed to compare anthropometric dimensions of nostrils in patients with and without dorsal nasal deformity. This observational, cross-sectional study was conducted in the ENT department of a tertiary care hospital from December 25, 2021, to June 15, 2023, after approval from the Institutional Review Committee (Reference number: 234(6–11)E2 078/79. Sixty-eight patients were equally divided into two groups: those with (group A) and without (group B) dorsal nasal deformity. Vernier caliper was used to measure nostril width and nasal ala flaring. Shapes of nostrils were assessed in both these groups and compared. An independent t-test was used to compare the widths of the right and left nostrils between the two groups. The Fisher–Freeman–Halton exact test was applied to assess differences in nostril shape, while Chi-square test was employed to compare the frequency of flared alae between the groups. Among 68 patients, the median age was 34 (IQR: 22 to 44) years with equal gender distribution (34 males, 34 females). Flared ala was observed in 28 (82.35%) patients of group A and 25 (73.53%) patients of group B. Mean nostril width was 13.99 ± 2.70&#xa0;mm (both sides) in group A and 13.37 ± 2.06&#xa0;mm (right) and 13.39 ± 2.08&#xa0;mm (left) in group B. Heart-shaped nostrils was the commonest nostrils shape in both the groups. Flared ala was common regardless of presence of dorsal nasal deformity. The commonest shape of the nostril was heart-shape.</p>
