Background: Age and sex determinations are important tools in forensic odontology which help in the identification of an individual. Radiographic method of sex and age estimation is a noninvasive simple technique. Measurements of the maxillary sinuses can be used for the estimation of age and gender when other methods are inconclusive. Maxillary sinus dimensions were used as an important tool in the identification of unknown. Aim: This study aims to estimate age and sex using the dimensions and volume of the maxillary sinus in magnetic resonance imaging (MRI). Materials and Methods: This study included sixty patients visiting Department of Radiology Mamata General Hospital, Khammam requiring MRI of the brain and paranasal sinuses. Maxillary sinus dimensions were measured using Siemens software, and statistical analysis was done. Results: The volume and dimensions of the maxillary sinus were more in males when compared to the females with a statistically significant difference. The highest percentage of sexual dimorphism was seen in the volume of left maxillary sinus. Age estimated using the volume of maxillary sinus showed no statistically significant difference from the actual age of the subjects. Conclusion: The dimensions and volume of the maxillary sinuses were larger in males than in females, in addition to that they tend to be less with the older age. MRI measurements of maxillary sinuses may be useful to support gender and age estimation in forensic radiology.
