Abstract：
BACKGROUND: Gender determination of deceased individuals may become necessary in scenarios involving sudden and unforeseen fatalities like explosions, fires, transportation accidents, or instances of mutilation or decomposition, which frequently require medicolegal expertise. Forensic radiology is instrumental in identifying gender. The shape of the frontal sinus is considered distinct for every person, differing even among identical twins, much like individual fingerprints and establishing personal identity.
OBJECTIVE: This study was designed to validate and determine gender identification by evaluating frontal sinus measurements using digital posteroanterior cephalograms with reference to Yoshino\'s classification and to determine gender based on measurements of frontal sinus size, bilateral asymmetry, the outline of the upper border of the frontal sinus, partial septa, and supraorbital cells of the frontal sinus.
METHODS: A total of 300 digital posteroanterior cephalograms (150 males and 150 females) of age groups ranging from 18 to 30 years were collected from the records of the Department of Oral Medicine and Radiology, Panineeya Institute of Dental Sciences & Research Centre, Hyderabad. The parameters that were assessed in a digital radiograph are Yoshino\'s frontal sinus pattern of the individual, which includes frontal sinus size, bilateral asymmetry, superiority of the side, outline of the upper border, partial septa, and supraorbital cells. The measurements were taken, tabulated, and compared with the standard values of the gender measurement. The values were subjected to statistical analysis.
RESULTS: Results showed a statistically significant difference in the mean height (p=0.000), width (p=0.000), area (p=0.000), partial septa (p=0.002), and outline of the upper border on the right side (p=0.011) of the frontal sinus for both males and females. The mean values for length, width, and area of the frontal sinus were higher in males than females. No statistical difference is found on the outline of the upper border on the left side, superiority of the side, and supraorbital cells. The application of discriminative analysis to the data accurately identified gender in 65.3% of the cases.
CONCLUSIONS: Thus, from the above study, the forensic application of frontal sinus morphology can be recommended as an adjunctive tool for gender determination.

摘要：
背景：在涉及爆炸等突然和不可预见的死亡的情况下，对死者进行性别确定可能变得必要，火灾,交通事故,或残害或分解的实例，这通常需要法医学专业知识。法医放射学有助于确定性别。额窦的形状被认为对每个人来说都是不同的，即使是同卵双胞胎，就像个人指纹和建立个人身份一样。
目的：本研究旨在通过参考Yoshino的分类使用数字后前脑图评估额窦测量来验证和确定性别识别，并根据额窦大小的测量来确定性别，双边不对称，额窦上缘的轮廓,部分隔片,额窦的眶上细胞.
方法：从口腔医学和放射科的记录中收集了300张年龄在18至30岁之间的数字后前头颅图（150名男性和150名女性），Panineeya牙科科学研究所和研究中心，海得拉巴.在数字射线照片中评估的参数是吉野的额窦模式，包括额窦的大小,双边不对称，优势的一面，上边界的轮廓，部分隔片,和眶上细胞.进行了测量，列表，并与性别测量的标准值进行比较。对值进行统计分析。
结果：结果显示平均身高有统计学上的显着差异（p=0.000），宽度（p=0.000），面积（p=0.000），部分隔膜（p=0.002），男性和女性额窦右侧（p=0.011）的上边界轮廓。长度的平均值，宽度,男性额窦面积高于女性。左侧上边界轮廓无统计学差异,优势的一面，和眶上细胞.应用判别分析对数据进行准确识别的病例占65.3%。
结论：因此，从上述研究来看，额窦形态学的法医应用可以推荐作为性别确定的辅助工具。
