“…This latest conclusion agrees with the results obtained by Motawei et al [9] , who investigated the frontal sinus using CBCT as a tool for sex differentiation and found that CBCT can be used to determine sex with an accuracy of 76.7%. However, another group of researchers investigated the frontal sinus using plane X-ray scans and found that sex could only be determined in 64.6% of the study sample [12] .…”

“…CT proved efficient, simple, rapid, reliable and safe as an imaging technique for forensic practice. CT has been demonstrated to be more accurate and more informative than routine X-ray and conventional CT methods in forensic practice [9] . We found CBCT to be reliable and safe with minimal radiation exposure.…”

Background: The determination of age and sex is crucial for establishing human identity. The mandible is an accessible and durable bone that is very useful in this respect. Aim:To assess the efficacy of measuring the mandible ramus length in the identification of age and sex in a group of Egyptians. Subjects and Methods:The length of the ramus of the mandible was measured in lateral craniofacial scans of 213 individuals (99 males and 114 females) with an age range of 7-58 years using cone-beam computerized tomography (CBCT). Results:Sexual dimorphism was not observed until age of 17 years in this sample. There was not found any significant differences in the length of the ramus of the mandible between males and females in the age range of 7 to less than 17 years (P-value = 0.2495). There was a significant difference between males and females for the mean length of the ramus in the age range of 17 to 58 years (P-value < 0.0000). It predicts sex with an accuracy of 67%. There was a positive correlation between and (age) and log e (ramus length) (r=0.73, P-value < 0.0001 for females and r=0.85, P-value <0.0001 for males). Therefore, it was possible to calculate each individual's age based on his or her mandible ramus length. Conclusion:The mandibular ramus length is valuable in age estimation and less valuable in sex determination. Computerized tomography examination is a safe and an accurate procedure with minimal radiation exposure, and provides valuable precise information regarding mandible measurements.

“…It was documented that significant difference in the dimensions between the males and the females were also observed. 23 In our study, the mean heights of the right frontal air sinuses were found to be greater in the males as compared to the females study participants. Variations in terms of mean heights were also recorded when left frontal sinuses were compared between the two genders.…”

Objective: To determine morphology and variation in dimensions of frontal air sinuses in male and female genders living in Karachi. Study Design and Setting: It was a cross sectional study and was conducted at Radiology Department, JPMC. Methodology: The total number of study participants were 216. The research subjects were divided into two equal groups of males and females each having 108 members. The mean age of the participants was calculated to be 35.14 ± 8.68 years. The study subjects were recruited from Radiology Department, JPMC, Karachi. After taking written informed consent, Water’s (occipito-mental) view radiography was done to measure the parameters of height, width and area of the frontal air sinuses. The included variables were the demographic data and the physical examination to exclude facial anomalies. All the measurements were recorded and the measurements were saved by the help of Radiant DICOM digital software. Results: The parameters of height, width and the area of frontal sinuses showed highly significant variability on both the right and the left sides. All the dimensions were highly significantly greater in the males as compared to the female study participants (p=0.000). The Independent-Samples T Test was applied to compare the two gender groups. Conclusion: The parameters of height, width and area of frontal sinuses were greater in the males as compared to the females on both the left and the right sides

“…This suggests that although there are sex differences evident within normal populations, i.e. in randomly selected unrelated individuals (Uthman et al ., 2010; Sai Kiran et al ., 2014; Benghiac et al ., 2015; Michel et al ., 2015; Akhlaghi et al ., 2016; Hamed et al ., 2016; Motawei et al ., 2016; Choi et al ., 2018), the sex differences are not noticeable within families. We do not have to take into account the sex of individuals when investigating family relationships.…”

Biological relationships and frontal sinus similarity in skeletal remains with known genealogical data

Frontal sinus analysis has potential utility for detecting biologically related individuals. However, the methodological approach to its evaluation, as well as its informative value, have been questioned. The aim of this work is to introduce a new approach to evaluating the frontal sinus using the ‘external supraorbital line’ (ESOL) and to determine whether there are sex differences within families in frontal sinus measurements and whether frontal sinus similarity reflects known genetic relationships in both measurements and morphology. We examined the skeletal remains of 41 adult individuals (25 males, 16 females), all members of one family over four generations (19th to 20th centuries), including individuals with very close consanguinity. CT images of skulls were acquired, and both the dimensions and morphology of the frontal sinuses were analyzed using their portions above the ESOL. No significant sex differences were found within families based on frontal sinus dimensions. Significant relationships were found between biological distance and the maximum height and morphology of the frontal sinuses. The greatest degree of similarity was found among closely related individuals. Additionally, in several cases, there was a greater degree of similarity between first cousins or grandparents and their grandchildren than among siblings or parents and their children. Total surface, volume and width are not significant indicators of relatedness. Known genetic relationships are also supported by individual morphological features. Variability within families with very close consanguineous relationships was lower than within families with common degrees of consanguinity, although differences are significant only for some variables.
