Background: Evaluation of maxillary sinus dimensions is important in correlation to age and gender by computed tomography. 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. Results: Similarly, there was a statistically significant association between the mean dimensions of height, width, depth, and volume of the right and left maxillary sinus, in the age group of 20-30years and in the age group of 31 - 40 years. In our investigations it was found that with the increase in age beyond 40 years, there was decrease in maxillary sinus dimensions and our other findings were similar to the previous reports. Conclusion: CT images provide invaluableinformation on the dimensions of maxillary sinus in different age groups and hence the study proved vital in identifying age. It was of paramount importance for clinicians and toplanning procedures by surgeons.
