“…On the other hand, some studies showed diversity results from ours as ElBeshlawy & Helaly who found that the FS index could only act as a poor sex predictor [11] . This might be due to their different methodology.…”

“…Frontal sinus is one of the imaged anatomical landmarks that is unique in shape and may be described as fingerprint-like individuality, hence frontal sinus index (FSI) can be used in personal identification for forensic purposes [8] . Previous studies measured FSI and correlated it to gender are not only limited and contradicting but also lack a reliable standardized way of application [9][10][11] .…”

Aim: To develop and assess a new protocol proposed for sex determination using frontal sinus index measured from two dimensional lateral cephalometric radiographs. Materials & Methods:The frontal sinus index was measured by two experienced radiologists and one experienced orthodontist on two hundred and one cephalometric scans (93 males & 108 females). The maximum height and width of the sinus were measured then the height to width ratio was calculated. The mean height to width ratio of the sinus were tabulated and subjected to statistical analysis to determine the correlation to gender.Results: There was a high statistically significant difference between the frontal sinus index measured between males and females groups. Conclusion:Frontal sinus index measured on lateral cephalometric radiographs by the developed protocol could be an indicator for gender identification in Egyptians and a larger sample multicentric study is recommended.

“…This may be due to the different skeletal characteristics of Indian population from Egyptian one with genetic dissimilarities and different dietary habits resulting in different anatomical features. 28 ElBeshlawy & Helaly, 2020 20 found that the FSI (Protocol 1) calculated from lateral cephalometric measurements was significantly higher in males than females above 18 years. Also, in their ROC analysis results, the FSI could only act as poor sex predictors (AUC: 0.66).…”

Objectives: To evaluate the accuracy of three different measurement protocols of frontal sinus index for sex estimation among a group of adult Egyptian population. Methods:One hundred and seventy-five retrospective digital lateral cephalometric radiographs of adult Egyptian individuals were included in this study (eighty males and ninety-five females). The maximum height and the maximum width (measured with 3 different methods) of the frontal sinus were measured, then three frontal sinus indices (FSIs) were calculated. All the measurements were statistically analyzed.Results: It was found that all the three FSIs calculated in this study were higher in females than in males with statistical significant difference. Moreover, using the ROC analysis, the area under the curve (AUC) of the three protocols was less than (<0.5) suggesting no discrimination. However, FSI (Protocol 1) had the highest value AUC, followed by FSI (Protocols 2 and 3). Conclusions:Although the frontal sinus is unique for each individual, the usage of the frontal sinus index for sexual discrimination needs more investigations and research on different populations. FSI (Protocol 1) may be a promising tool for sex estimation. Its sensitivity and specificity may improve when combined with other frontal sinus morphological parameters.
