ABSTRACT
Background: Bicondylar diameter of the mandible varied among sexes. Sexual dimorphism on the basis of anthropometric analysis of bicondylar diameter has immense significance medicolegally. Lower jaw fracture with condylar displacement is common in road traffic accident. Resection of the mandible is indicated in carcinoma or osteomyelitis of the bone. For optimal occlusion, bicondylar diameter of the mandible must be maintained. Bicondylar diameter is useful tool for any reconstructive surgeries of lower jaw. Hence this study is aimed at to provide range of bicondylar diameter for accurate determination of sex and for effective surgical endeavour at this region.
Methods: Three hundred intact, dry mandibles of unknown sexes were studied. Distance between mandibular condyles was measured. All the data were analyzed for significance of the occurrence in relation to sex by means of paired t-test.
Results: The average bicondylar diameter was 117.59 mm in male and 107.61 mm in female. By comparing the data with non-metric analysis of the mandible, we got 97% accuracy in determination of sex. We found statistically significant difference among sexes.
Conclusions: Accurate determination of sex from mandible required wide number of data that could be utilized medicolegally and clinically.
Key words: Anthropometry, Bicondylar diameter, Reconstruction surgeries, Sexual dimorphism.
