A STUDY ON THE RELATIONSHIP BETWEEN THE GLENOID FOSSA POSITRON AND VARIOUS SKELETAL DISCREPANCIES

악안면 골격부조화와 관절와위치간의 상관관계에 관한 연구

This study was designed to compare extreme variations in facial growth in order to examine the relationships between the glenoid fossa position and skeletal malocclusions. It was hypothesized that patients with large mandibular plane-sella nasion angles would have a more superior fossa position than patients with small mandibular plane-sella nasion angles. It was also hypothesized that patients with large ANB angles would have a more posterior fossa position than patients with small ANB angle. For this study, the data from lateral roentgenocephaloprams of 72 Females and 72 males aged from 10 to 18 years were used. The results were as follows 1. In the case of large ANB angle, glenoid fossa position was relatively posterior than that of small ANB angle in Female, but it was not significant in male. 2. In the case of large APDI, glenoid fossa position was relatively anterior in female, but it was not significant in male. 3. In the case of large SN-Go Gn angle, glenoid fossa position was relatively superior in both male and female. 4. In the case of large ODI, glenoid fossa position was relatively inferior in both male and female.
