Purpose: Person recognition via radiographs has always been a fertile ground for deciphering skeletal developmental patterns and yielding promising results. This study was performed to evaluate the uniqueness and reliability of the frontal sinus by comparing various parameters on the digital posteroanterior skull radiographs for sex identification. Materials and Methods: The present study comprised digital posteroanterior radiographs and frontal sinus was analyzed for morphometric parameters by Adobe® Photoshop® CS3 extended in 30 subjects (15 males and 15 females) aged between 18 and 40 years. The comparison of values was done and accuracy of sex determination was assessed. Results: Statistically significant difference was found. The mean values for length, width, and area of the left frontal sinus were found to be higher in males as compared to females. Conclusion: The frontal sinus provides average accuracy in sex determination as it is unique to every individual and ultimately this can aid in human identification. Posterioanterior skull radiographs have proven to be a potential valid tool for individual identification.
