Abstract:
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 supenor 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 postenor 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 positron 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.
