“…In this study, while a significant sex difference was found in the length and height of maxillary sinus, there was no significant difference between sexes in maxillary sinus width. These results were in line with the findings reported by Fernandes et al In accordance with the current study, Attia et al found statistically insignificant lower values for maxillary sinus width between males and females. On the other hand, according to the results achieved in some previous studies, when compared with females, males had significantly wider maxillary sinuses .…”

“…In this study, among the measured parameters, the maxillary sinus height was the best discriminating variable for sexual dimorphism. Uthman et al and Attia et al showed that the maxillary sinus height was the best discriminating variable which was consistent with our study. However, Ahmed et al indicated that maxillary sinus width was the best discriminant parameter.…”

Sex determination of unknown persons plays an important role in forensic medicine. Cone-beam computed tomography (CBCT) is an excellent imaging modality for accurate measurement of maxillary sinus dimensions. This study aimed to evaluate whether maxillary sinus measurements on CBCT scans can be applied for sex determination. The width, length, and height of maxillary sinuses in CBCT images of 100 patients (50 males and 50 females) were measured. Student's t-test and discriminant function analysis were used to compare differences in the measured parameters between males and females. The correct predictive accuracy rate of sex determination was 78% in females and 74% in males with overall accuracy of 76%. Based on discriminant analysis, the most pronounced variable in differentiation of sex groups was maxillary sinus height. This study suggests that maxillary sinus measurements can be valuable for sex determination in forensic investigation, especially for cases in which other traditional methods are not applicable.

Background:Individual identification is a subtle concept and often one of the most important priorities in mass disasters, road accidents, air crashes, fires, and even in the investigation of criminal cases. Matching specific features detected on the cadaver with data recorded during the life of an individual is an important aspect in forensics, and can be performed by fingerprint analysis, deoxyribonucleic acid matching, anthropological methods, radiological methods and other techniques which can facilitate age and sex identification. Sinus radiography is one such method that has been used for determination of the sex of an individual. Hence, an attempt is being made to use the different dimensions of the maxillary sinus in the determination of sex using coronal and axial sections of plain computed tomography (CT) scan.Materials and Methods:A total of 30 patients including 17 male and 13 female, visiting the Outpatient Department of the Mamata General Hospital were included as the study subjects. The dimensions of right and left maxillary sinuses of 30 subjects from plain CT were measured using SYNGO software and statistical analysis was done.Results:Sex determination using height, length, width, and volume of the maxillary sinus on both sides showed statistically significant results with a higher percentage of sexual dimorphism in the case of volume.Conclusion:Volume of the right maxillary sinus can be used as accurate diagnostic parameter for sex determination.

“…4,5 In view of that, there are a number of studies stating the importance of maxillary sinuses in forensic medicine, especially for gender determination, where the dimensions of sinuses between males and females are compared by means of various imaging methods. [5][6][7][8][9][10][11][12][13][14] The results of most of these studies suggested the utility of the maxillary sinuses in gender determination. Almost all these studies reported that the sinus measurement values (dimensions and volume) are larger in males than in females and they correlated this fact with the differences in the overall stature of males and females.…”

Background. It is impossible to use the routine skeletal parts for gender identification if the skeleton of unknown human remains is obtained in a fragmented and incomplete state. The alternative is to use other parts of the skeleton for gender identification.Objectives. The objective of this study was to assess the utility of the morphometry of the maxillary sinuses using computed tomography (CT) for gender determination.Material and methods. The study, approved by the institutional ethics committee, analyzed CT scans of 200 patients (100 males, 100 females). The measurement of the mediolateral (ML), superoinferior (SI) and anteroposterior (AP) dimensions, as well as of the volume and the antero-lateral (AL) angle of both the maxillary sinuses, was performed using a CT scan. Head circumference and head area were also measured on an axial image in order to evaluate the correlation between the sinus volume and the head circumference and head area.Results. The mean of the mediolateral, superoinferior and anteroposterior dimensions, volume and AL angle of the right and left maxillary sinuses showed a statistically significant difference between males and females. Head circumference as well as head area were observed to be greater in males than in females, with a statistically significant difference. A positive correlation was observed between the volume of maxillary sinuses and the head circumference and head area on both sides and in both genders; however, it was not significant. Amongst all the parameters, the left AL angle with a 78.5% accuracy was found to be the best discriminative parameter, followed by the right AL angle with a 73% accuracy. The overall accuracy of the maxillary sinus parameters to identify gender was 86%. Conclusions.The maxillary sinus measurements, as well as head circumference and head area are valuable parameters for sex determination in forensic medicine, with a relatively good accuracy rate. However, the prediction rate can be increased by including the AL angle of the maxillary sinus.Słowa kluczowe: zatoka szczękowa, obwód głowy, powierzchnia głowy, ustalanie płci Cite asDangore-Khasbage S, Bhowate R.
