Radiographic assessment of frontal sinus morphology for gender determination using paranasal sinus view

Frontal sinus morphometry shows forensic promise for gender determination, yet paranasal sinus radiographs remain underexplored compared to CT-based assessments despite their accessibility. Therefore, it is of interest to evaluate frontal sinus dimensions (area, width, height) in 300 healthy adults (>20 years) using standardized paranasal sinus views with digital measurement techniques. Right frontal sinus height emerged as the most reliable predictor, achieving 69% accuracy for gender discrimination across all measured parameters. Paranasal radiographs demonstrated clinically viable predictive performance, particularly for height-based analysis compared with area- or width-based metrics. Thus, we document paranasal sinus views as a practical, cost-effective forensic tool for gender estimation when advanced imaging is unavailable.
