Background: The aim of the study was to investigate the association between the position of tongue, soft palate, pharyngeal airway and hyoid bone in skeletal Class I, Class II and Class III patterns.153 subjects were selected from the Out- patient department of the Post-Graduate Department of Orthodontics & Dentofacial Orthopaedics, Government Dental College & Hospital, Srinagar, India. Five different parameters were used to divide the lateral cephalograms into skeletal Class I , Class II, Class III, 51 subjects were included in each group, these groups were further sub divided on thebasis of gender. SPSS (Version 16.0) and Microsoft Excel software were used to carry out the statistical analysis of data. Student’s independent t-test was employed to test the differences between males and females. Analysis of variance (ANOVA) was used to determine whether significant differences existed between the groups. Least significant difference (LSD) test was applied to identify which pair of the groups were different. Results:On comparing female and male subjects within the same skeletal patterns , we found that position of hyoid bone is higher in female subjects in relation to RGN-C3 in Class I Skeletal pattern (p<0.01) than male subjects. In Class III skeletal pattern , soft palate length, vertical airway length were found to be longer in male subjects, and hyoid bone was more anteriorly positioned in comparison to female subjects. While making over all comparison amongst groups, statistically significant difference was observed  in tongue length, soft palate length, superior posterior, middle and lower airway length and hyoid position in Class I, Class II & Class III skeletal patterns. Conclusion: Uvulo-glosssso-pharyngeal dimensions have a positive correlation with different antero-posterior skeletal pattern.
Key words: Skeletal Patterns, Tongue Position, Pharyngeal Airway, Hyoid Bone.
