BACKGROUND: Hyperostosis Frontalis Interna (HFI) is a localized thickening of the inner table of the frontal bone, frequently observed in postmenopausal women. Although often overlooked, it may provide valuable information for reconstructive identification in forensic contexts.
METHODS: We conducted a macroscopic analysis of 195 autopsied individuals at Limoges University Hospital (France) to assess the prevalence of HFI and its associations with age, sex, and medical history.
RESULTS: HFI was identified in 13.8 % of cases, with a striking sex disparity: 38.8 % of females presented with HFI compared to only 0.78 % of males (p < 0.0001). A significant association with older age was observed (mean age 66.3 years in HFI-positive vs. 48.4 years in HFI-negative individuals, p < 0.00001). The presence of HFI predicted female sex with a positive predictive value of 96.3 %. A significant association was also found with a history of depression.
CONCLUSION: Although HFI has limited sensitivity, its high specificity and ease of detection make it a useful auxiliary marker in reconstructive identification. It may help narrow the biological profile in cases involving degraded or incomplete remains. Further multicenter studies are needed to validate its forensic utility.
