Background & Objective: The disturbances of orofacial functions lead to abnormal growth and development of the orofacial complex. The objective of the study was to determine the position of the hyoid bone in skeletal Class II & skeletal Class III subjects and it the position was affected by different skeletal patterns.
Methods: In the sample size of 102 was calculated using Cohen’s formula, 102 lateral cephalograms were taken, (51 girls and 51 boys, aged 14-33 years) which were segregated using five different skeletal parameters into skeletal Class II & Skeletal Class III. All lateral cephalograms were traced and Independent t – test was used for the comparison. SPSS software was used for final analysis.
Results: Hyoid bone is anteriorly placed in males (P<0.05). Overall comparison between Class II, Class III subjects, Hyoid bone was more posteriorly situated in Class II subjects compared to Class III subjects and is statistically significant (P<0.001).
Conclusion: The sagittal skeletal pattern may be a contributory factor in variation position of hyoid bone, Hyoid was more posteriorly placed in Class II subjects than in Class III was most.
