“…showed that the mean height and width of the frontal sinus were significantly greater in males, while the ratio of height to width of the frontal sinus in females was significantly higher than that in males. [ 2 ] This finding was in line with the current results. However, in our study, this difference did not reach statistical significance, which may be due to our small sample size.…”

Objective:This study aimed to determine the cephalometric association of mandibular size/length to the surface area and dimensions of the frontal and maxillary sinuses.Materials and Methods:This descriptive study was conducted on 116 digital lateral cephalograms of 38 patients with skeletal Class I malocclusion (normal), 40 patients with skeletal Class II malocclusion with mandibular deficiency, and 38 patients with skeletal Class III malocclusion with mandibular excess. Both male and female patients were included. Using AutoCAD 2016 software, the anteroposterior dimension, height and surface area of the frontal and maxillary sinuses, mandibular body length and cephalometric indices including anterior and posterior cranial bases, and growth pattern indices were measured on lateral cephalograms.Results:Dimensions and surface area of the frontal and maxillary sinuses in skeletal Class III malocclusion were greater than those in other groups. These variables were significantly correlated with the mandibular body length. The coefficient for the correlation of height, width, and surface area of the frontal sinus with mandibular body length was 0.253, 0.284, and 0.490, respectively. The coefficient for the correlation of height, length, and surface area of the maxillary sinus with mandibular body length was 0.346, 0.657, and 0.661, respectively. These variables (except for the frontal sinus width) had a significant correlation with the anterior and posterior cranial bases. The frontal sinus width had a significant correlation with the anterior cranial base. These variables in males were greater than those in females.Conclusion:The dimensions and surface area of the frontal and maxillary sinuses in skeletal Class III malocclusion were greater than those in other groups. These variables (except for the frontal sinus width) had a significant correlation with the anterior and posterior cranial bases and mandibular body length.

“…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.

“…However, when they combined skull measurement and frontal sinus measurement, they obtained an accuracy of 85.9% in sex identification. Kiran CS et al 11 framed that the dimorphic features of frontal sinus in both men and women, there was significant differences observed in the frontal sinus parameters. We developed the regression equation which can be used to determine sex using frontal sinus among Indian population.…”

In modern life many disasters, accidents, natural calamities occur & identification of living or dead persons in such incidents are tough task since the field of forensic come into existance to deal with identification of a person for medico legal purpose. Aim: To determining the gender of individuals by mathematical method using measurement of the frontal sinus through para nasal sinuses radiograph. Material and Method: The study group consist of about 48 person both male and female are included. Digital Para nasal sinuses radiograph will be taken using standard technique for the evaluation of frontal sinus. Radiographic digital images will be imported and later area (height×width×area) of the frontal sinus will be evaluated. Conclusion: The accuracy obtained in this study may be due to individual variation of frontal sinus is too great to attempt sex determination from this structure.
