“…The above data suggested that mean width and height of FS is greater in males as compared to females and can be used as a criterion for gender determination in forensics which was in accordance with the studies published by Yoshino M (1987) 17 and Verma K et al (2017). 1 The present study is in accordance with the studies conducted by Nagaraj T et al (78% and 11.4%) 15 and Verma K et al (77.5% and 22.5%) 1 stating that FS symmetry and asymmetry were found to be 55.14% and 23.57%, respectively. Unilateral absence of FS was seen in 86 (12.2%) of 700 individuals.…”

“…Unilateral absence of FS was seen in 86 (12.2%) of 700 individuals. These findings are in accordance with the studies done by Verma K et al (2017) 1 and Tiwari P et al (2016) 14 with 8.7% and 13.75% cases respectively and in contrast to the studies done by David M P et al (2010), 9 Gopal et al (2017) 18 and Nagaraj T (2017) 15 who observed 6%, 2.5% and 5.7% respectively.…”

“…In the present study, Bilateral aplasia was found to be 63 (9.0%) in our study which was in total contrast with the studies done by Gopal et al (2017) 18 who did not observe in any case, David M P et al (2010) 9 with 4%, Tiwari P et al (2016) 14 with 5% and Nagaraj T et al (2017) 15 The present study was conducted using only one radiograph which adequately demonstrates FS morphology with minimal distortion and maximum detail. Similar studies published in literature which involving morphometric analysis using one radiograph were conducted by Reddy S et al (2014), 20 Mohan V et al (2015), 21 Nagaraj T et al (2017) 15 and Verma K et al (2017). 1 However, in contrast, Camargo RJ et al (2007), 11 Rubira-Bullen IRF et al (2010) 16 and Patil N et al (2012) 5 used Caldwell view in their studies.…”

“…1,9,[11][12][13][14] While in some studies published in 2015 (Verma P et al) and 2017 (Nagaraj T) includes unequal distribution of males and females. 6,15 Similarly, another study published in 2010 includes 116 males and 29 females. 16 The mean width of FS in males and females was 57.83 ± 5.59 mm and 36.27 ± 6.62 mm respectively while the mean height with SD in males and females was 24.76 ± 3.48 mm and 18.83 ± 2.82 mm Therefore, the differences of males and females dimensions were statistically significant in both the genders with p-value of 0.000.…”

Introduction: Human radiography plays a major role for personal and gender identification in case of natural disasters such as earth quacks, tsunamis, etc. when human remains are decayed or deceased. The uniqueness in dimensions and patterns of the frontal sinus (FS) lead to advances in forensic dentistry. Aim: To evaluate the dimensions and patterns of FS as observed on posterior-anterior (PA) cephalogram for personal and gender identification. Materials and Methods: A total of 700 PA Cephlograms, 350 males and 350 females were selected. The mean dimensions and patterns of the FS in males and females were determined and evaluated. Results: On intergroup comparison, the difference in dimensions of males and females were statistically significant with p-value of 0.000. The present study revealed that out of 700, FS symmetry and asymmetry was observed in 386 (55.14%) and 165 (23.57%) individuals respectively. The FS aplasia was seen in 149 (21.2%) individuals. Conclusion:The morphometric analysis of FS can serve as an adjunct to other methods of personal and gender identification.

“…In our study, males and females were equal in number i.e 70 males and 70 females (50% each), which is similar to the studies conducted by Verma K et al (2017) 4 15 . In contrast to these, 150 males and 130 females were taken in study published by Nagarj T (2017) 16 and 74 males and 75 females were enrolled in study published by Verma P et al (2015) 7 . In Cakur B et al (2011) 17 study, 190 males and 220 females were included.…”

Background and aim: The shape and developmental stages of the frontal sinus (FS) differ in each individual, it can be used to determine sex and identity. This study aimed to assess the morphological structure of the FS diameters in sex determination using posterioanterior (AP) skull radiography. This data can be valuable for identifying and characterizing human features.Methods: The study included 350 patients (171 females, 179 males) aged between 20 and 55 years who underwent AP skull radiography. FSs were classified as symmetrical, asymmetrical, unilateral, or bilateral aplasic. The right and left FS height and width measurements were made based on the largest diameters.Results: The mean age was 32.8±11.45 years for the whole sample. The mean age of the males was 31.23±11.9 (20-51) years and that of the females was 34.45±10.75 (20-55) years. When classified anatomically, 20 patients had bilateral aplasia (12 males, eight females), 19 patients had right aplasia (10 males, nine females), and 11 patients had left aplasia (seven males, four females). FS was symmetrical in 206 (72.1%) patients while right dominance was observed in 33 (9.43%) patients and left dominance in 61 (17.43%) patients. The FS height and width values on both sides were statistically significantly higher in males than in females (p<0.001 for each parameter). The females were accurately classified at a rate of 71.2% and the males at 68.2%. Conclusion: Notably, our research has revealed that frontal sinus diameters are consistently larger in males than in females, and that direct radiography can be employed for gender determination with an accuracy rate of 69.7%. This information underscores the utility of morphometric evaluation of the frontal sinus diameters on direct radiography for gender and identity determination, potentially in conjunction with other parameters. In conclusion, our study has demonstrated the potential of the morphological structure of the frontal sinuses as a valuable tool for identifying and characterizing human individuals.
