%X <B>BACKGROUND: </B>Gender determination of deceased individuals may become necessary in scenarios involving sudden and unforeseen fatalities like explosions, fires, transportation accidents, or instances of mutilation or decomposition, which frequently require medicolegal expertise. Forensic radiology is instrumental in identifying gender. The shape of the frontal sinus is considered distinct for every person, differing even among identical twins, much like individual fingerprints and establishing personal identity.<BR><B>OBJECTIVE: </B>This study was designed to validate and determine gender identification by evaluating frontal sinus measurements using digital posteroanterior cephalograms with reference to Yoshino's classification and to determine gender based on measurements of frontal sinus size, bilateral asymmetry, the outline of the upper border of the frontal sinus, partial septa, and supraorbital cells of the frontal sinus.<BR><B>METHODS: </B>A total of 300 digital posteroanterior cephalograms (150 males and 150 females) of age groups ranging from 18 to 30 years were collected from the records of the Department of Oral Medicine and Radiology, Panineeya Institute of Dental Sciences & Research Centre, Hyderabad. The parameters that were assessed in a digital radiograph are Yoshino's frontal sinus pattern of the individual, which includes frontal sinus size, bilateral asymmetry, superiority of the side, outline of the upper border, partial septa, and supraorbital cells. The measurements were taken, tabulated, and compared with the standard values of the gender measurement. The values were subjected to statistical analysis.<BR><B>RESULTS: </B>Results showed a statistically significant difference in the mean height (p=0.000), width (p=0.000), area (p=0.000), partial septa (p=0.002), and outline of the upper border on the right side (p=0.011) of the frontal sinus for both males and females. The mean values for length, width, and area of the frontal sinus were higher in males than females. No statistical difference is found on the outline of the upper border on the left side, superiority of the side, and supraorbital cells. The application of discriminative analysis to the data accurately identified gender in 65.3% of the cases.<BR><B>CONCLUSIONS: </B>Thus, from the above study, the forensic application of frontal sinus morphology can be recommended as an adjunctive tool for gender determination.
