An evaluation of Glenoid Fossa Location in various Facial Divergence Types

Background: To study the variation in the anatomical position of glenoid fossa in patients with long face and short face. The study was conducted to assess the location of Glenoid Fossa in various facial divergence types. Material & Methods: Glenoid fossa location is ascertained in cephalometric radiographs of subjects with different facial types. Glenoid fossa location in cranial base was assessed using four linear and two angular variables on cephalometric data of 184 subjects. Data was analyzed using IBM SPSS Statistics, version 25, predictive analytics software. Statistical analysis used Bonferroni Correction for multiple comparisons and Kruskall Wallis test in place of oneway ANOVA if the data was not normally distributed. Results: Hyperdivergent facial types have glenoid fossa located significantly superiorly in the cranial base as compared to hypodivergent facial types (p = 0.0163). Conclusions:The glenoid fossa location amongst hypodivergent and hyperdivergent facial types varies significantly. The glenoid fossa is located superiorly in cranial base in hyperdivergent facial types as compared to hypodivergent facial types.
