Objective: Radiographs of the frontal sinus have been used in personal identification due to its uniqueness configuration. Largely there has been little agreement regarding the reliability of frontal sinus in gender determination. This study was performed to verify the dependability of radiomorphologic features of the frontal sinus in the assessment of sexual dimorphism. Methodology: A total of 100 paranasal radiographs were evaluated for sexual dimorphic features including number of scallops on the sinuses' superior border, unilateral/bilateral presence or absence of partial septa, number of partial septa, and unilateral/bilateral presence or absence of supraorbital cells. Results: Application of discriminative analysis to the data accurately identified the gender in merely 65.7% of cases. Conclusion: Therefore the radiomorphologic features of frontal sinus alone have limited value in gender determination and may be used as an auxiliary method.
