Radiomorphometric Evaluation of Orbit and Inter-Orbital Distance for Gender Determination

ABSTRACT

Introduction: Anthropometry deals with obtainingmeasurements of anatomical structures to assist in identifyingthe age, stature, gender and several aspects related to individualor ethnic group. Orbital measurements and inter-orbitaldistance are one of the craniofacial parameters that couldbe used in gender identification in terms of anthropologicalstudies. Study aimed to measure the width of the orbitalapertures on Postero-anterior skull radiographic view, tomeasure the height of the orbital apertures on Postero-anteriorskull radiographic view, to measure the interorbital distanceon Postero-anterior skull radiographic view and to determinegender from radiomorphometric evaluation of orbit and interorbital distanceMaterial and Methods: In this study, a total of 100retrospective postero-anterior radiographs were selected fromdepartment’s collection using KODAK-8000 panoramic andcephalometric system following radiation protection protocol.Subjects were in the age range of 18 to 50 years. The maximumwidth and height of orbit and inter-orbital distance of theorbits were measured using masterveiw software (Version4.5.1). The data obtained was analyzed by using student“t” test.Results: The mean orbital width in males was 4.91 andfemales was 4.97. The observed mean difference wasstatistically significant (P-0.005). The mean orbital height inmales was 4.96 and females was 4.86. The observed meandifference was statistically significant (P-0.001) The meaninter-orbital distance in males was 3.37 and females was 3.00.The observed mean difference was statistically significant(P-<0.001)Conclusion: Hence we conclude that orbit and inter-orbitaldistance can be used in determining the gender.
