Sex determination using maxillary sinus

Abstract

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.

Cephalometric Analysis for Gender Determination Using Maxillary Sinus Index: A Novel Dimension in Personal Identification

“…The correct predictive accuracy was found to be 70.8% in males and 62.5% in females [3]. Kanthem et al (2015) found that the dimensions and volume of maxillary sinuses of right and left side using computed tomography were markedly larger in males compared with females [1]. All the results of the aforementioned studies were nearly analogous to the present study.…”

“…The precision rate is 98% in cases of pelvis and cranium, 95% in pelvis and long bones, and 80–90% only with long bones [3, 5]. Gender can be determined by various methodologies such as sexual dimorphism with tooth morphology, pulpal DNA analysis, study of lip prints, palatal rugae, and finger prints and even with radiological techniques by morphometric analysis of paranasal sinuses [1]. …”

Cone Beam Computed Tomographic Assessment of Maxillary Sinus Volume Variability Among Adult Egyptians

“…In the present study, males showed statistically significant higher mean sinus volumes than females in both the right and left sides. These results were in line with Kanthem et al (34) who found that the dimensions and volume of maxillary sinuses were notably larger in males compared with females. They documented statistically significant values with a higher rate of sexual dimorphism in volume with 85.46% for the right side and 78.38% for the left side.…”

Assessment of paranasal sinus parameters according to ancient skulls’ gender and age by using cone-beam computed tomography

“…In a study done by Kanthem et al [12] the dimensions and volume of maxillary sinuses of right and left side were much larger in males than in females. Sexual dimorphism according to volume was estimated at 85.46% for right side and 78.38% for left side.…”
