Relationship of Mandibular Morphology, Tongue Position, Airway and Hyoid Bone in Class III Malocclusion

Kulsum Guroo, Mohammad Mushtaq

Abstract :

Objective: The aim of the study was to investigate the relationship of mandibular morphology and various uvulo–glossopharyngeal structures in class III malocclusion. Materials and Methods: The study used lateral Cephalograms of 25 subjects exhibiting skeletal Class III pattern. All Lateral Cephalograms were traced by a single operator and statistically analyzed. Results: The results revealed a positive correlation between Tongue length, MAS, VAL, HRGN, C3H, RH, and mandibular length (p<0.05). TGH has a Positive correlation with VAL, RH and ML. SPAS has positive correlation with MAS, IAS, HRGN, C3H, RH, and ML. MAS has positive correlation with IAS, MH, HRGN, C3H, RH, ML. IAS has positive correlation with HRGN, C3H, RH, and ML. VAL has positive correlation with MPH, and ML Conclusion: The uvuloglosso–pharyngeal structures: Tongue Position, Airway, Hyoid Bone and mandibular morphology show a significant correlation with each other suggesting to have a contributory factor in causing a certain type of skeletal pattern.
