Objective: The aim of present study was to assess the age and sex related changes in Haller cells height and width.This study also help in prediction of age of an individual if Haller cell height/ width is known. Material and Methods: The study population consists of 152 study subjects with age range from 7 to 74 years. The CBCT images of 152 study subjects were analysed prospectively. All the CBCT images are obtained at 90 Kvp,4 mA for 11.3 seconds at FOV(17"x13.5") voxel size of 300. The height and width of haller cell is measured by using Trophy Dicom Ink software programme on coronal images (DICOM images). Results: There was no statistically significant (P>0.05) co-relation between Haller cells height and width (right side) and age groups noted. The mean Haller cell height in right side was statistically significant (P<.05) in male and female. It was higher in females than males. Haller cell width in left side is directly associated with age of females and demonstrated a significant positive relation. Conclusion: The morphometric evaluation of haller cells can be used for age and sex determination in medico-legal cases, evidence lacking incidents etc.
