| The purpose of this study was to verify the position of the glenoid fossa for both genders in subjects with different sagittal and vertical skeletal patterns. A lateral cephalometric study was carried out on 124 subjects (45 male and 79 female) aged 18-30 years who were classified according to skeletal sagittal relationships using ANB angle into three groups {Cl. І =48 (13 male and 35 female), Cl. ІІ =41 (14 male and 27 female), Cl. ІІІ =35 (18 male and 17 female)} subjects, and according to skeletal vertical relationships using MP-SN angle into three groups {normal angle=67(17male and 50 female) , high angle=23 (8 male and 15 female), low angle=34 (20 male and 14 female)} subjects. Cephalometric analysis comprised both sagittal and vertical measurements for the assessment of the position of the glenoid fossa in relation to surrounding skeletal structures. The assessment was achieved by measuring two angular and six linear variables using the AutoCAD computer program 2008. The results revealed that in sagittal skeletal relation, the glenoid fossa position didn’t differed in skeletal Class I for both gender, while in skeletal CL.ΙΙ and CL.ΙΙΙ the glenoid fossa position was more cranial in male than female, while in the vertical plane; the position of the glenoid fossa relative to Basicranial structures was more posterior in male than female for normal angle subjects and more cranial in male than female for high angle subjects when compared with subjects with low angle vertical relationships. In conclusion, subjects with high angle vertical relationships show a more cranial position of the Glenoid Fossa in male group in relation to cranial base when compared to subjects with either normal or low angle vertical relationships regarding the vertical plane and more cranial in male group in skeletal CL.ΙΙ and CL.ΙΙΙ regarding the sagittal plane. | ||
