Abstract
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.
