Summary
Forensic radiology can determine gender using frontal sinus morphology. Measurements of frontal sinus size and shape in digital cephalograms showed significant differences between males and females, aiding identification.
Area of Science:
- Forensic Radiology
- Anthropology
- Medical Imaging
Background:
- Gender determination is crucial in medicolegal cases involving unidentified remains.
- Frontal sinus morphology offers unique, individual characteristics for identification.
Purpose of the Study:
- To validate gender identification using frontal sinus measurements from digital posteroanterior cephalograms.
- To assess Yoshino's classification and various frontal sinus parameters for sex determination.
Main Methods:
- Analysis of 300 digital cephalograms (150 males, 150 females) aged 18-30.
- Evaluation of frontal sinus size, asymmetry, upper border outline, partial septa, and supraorbital cells.
- Statistical analysis and discriminative analysis for gender identification.
Main Results:
- Significant differences found in frontal sinus height, width, area, and right-sided upper border outline between genders (p<0.05).
- Males exhibited larger mean frontal sinus dimensions (length, width, area) than females.
- Discriminant analysis achieved 65.3% accuracy in gender identification.
Conclusions:
- Frontal sinus morphology serves as a valuable adjunctive tool in forensic gender determination.
- Digital cephalometry provides a reliable method for assessing these forensic markers.
