Background. Correlation of normal morphometry of maxillary sinus with age in a subset of north indian adult population CT measurements of maxillary sinus are useful in age estimation and in clinical procedures. Method: A morphometric analysis using Computed Tomography (CT scans) of the maxillary sinus of 118 individuals were taken for the study were divided into three age groups that is from 20-30 years, from 31-40 years and from 41-50 years and their measurements were recorded from right side maxillary sinus as well as from left side maxillary sinus. Maxillary sinus Cranio-caudal diameter, Transverse diameter, Anteroposterior diameter and volume were measured and then subjected to statistical evaluation in order to determine mean difference, t-value, p-value for evaluation.
