ABSTRACT

Introduction: Human are slightly sexually dimorphic. It has been reported that the skull, pelvis and long bones can be used for identification of gender. Maxillary sinus can be used for identification. CT scan is useful radiological technique to find out dimensions of maxillary air sinus. The aim of this study is to determine the reliability and accuracy of maxillary air sinus dimensions, i.e. anteroposterior, diameter, width, height in estimating sexual difference. Material and methods: The present study was an observational study in which CT images of 100 adult individual in the age group of 18-60 years of age either sex (50 male and 50 female) attending the Department of Radiology of G.R. Medical College, Gwalior (M.P.). We use (128 slice) multi detector spiral CT scanner. Parameter measured on the right and left maxillary sinus are as follows:  The transverse diameter was measured on coronal reconstructed image from outermost point of lateral wall of maxillary sinus to the medial wall.  The antero-posterior diameter was measured on sagittal reconstructed image as longest length antero-posteriorly.  The height was measured on coronal reconstructed image from the uppermost point of superior wall of the sinus to the lowest point on the inferior wall. Results: The result of present study revealed that a significant sex difference was found in maxillary air sinus with anteroposterior diameter. Left anteroposterior diameter was the best discriminate variable (p=0.0002) between gender. Conclusion: In this study on comparing the right and left maxillary air sinus statistically non- significant difference were found between male and female for anteroposterior diameter, width and height. On comparing the finding between the male and female statistically significant difference were found in anteroposterior diameter and width of maxillary air sinus.
