Aim: To determine the nasal indices of fetuses of Manipuri population in order to classify the nose type and to derive at a regression equation for determining gestational age from nasal dimensions. Materials and Methods: Sixty four Manipuri fetuses, between 12 weeks and 40 weeks of gestation were used. Nasal height and width were measured using vernier caliper. The data obtained were subjected to statistical analysis using descriptive statistics, Pearson correlation 'r', and linear regression model were used. Results: A statistically significant correlation between gestational age and nasal height (r = 0.89, P < 0.01) as well as nasal breadth (r = 0.85, P < 0.05) were observed. The nasal index of a Manipuri fetus at full-term was platyrrhine/chamaerhine. Conclusion: The nose of fetuses of Manipuri population at birth is platyrrhine which is round and wide. Its relevance may be found in forensic and clinical practice.
