ABSTRACT
Background: Many studies were carried out to investigate the forensic significance of ‎frontal sinus imaging, presuming that they could help in age and sex determination. ‎Objectives: This study aimed to assess the reliability of RibeiroFde's criteria versus CT in ‎measuring the frontal sinus dimensions and to propose its feasibility as a personal ‎indicator for age and sex identification in an Egyptian population sample.Materials and ‎methods: This is a descriptive cross-sectional study, in which seventy three (73) Egyptian adult patients ‎were recruited. Paranasal coronal CT scan and AP radiograph examinations were ‎performed for each patient. Frontal sinus Ribeiro Fde's measurements on plain radiograph ‎and CT diameters were measured.Results: Both plain radiograph and CT are simple and ‎reliable methods for frontal sinus analysis. This study showed that both modalities could ‎aid in the sex identification with variable predictive values, those were in favor of CT.As ‎for age estimation, both show comparable reliabilities in age estimation, the largest frontal ‎dimensions as estimated by either of the imaging tools, were found in the age range of ‎‎50-60 years. However, both show poor discrimination power. Conclusion: This study ‎results is suggesting that the frontal sinus could be used for sex and age identification. ‎
