Objectives: To test the hypothesis that there is no positive correlation between skeletal Class II and mandibular morphology with pharyngeal dimensions in subjects with different growth patterns. Materials and Methods: Lateral cephalograms of 60 patients were collected and divided into 2 groups, comprising of 30 in each group. Group 1 consisted of cephalograms of patients having Class I malocclusion, and was further divided into subgroups. 1a) Class I with normal growth 1b) Class I with vertical growth. Group 2 consisted of cephalograms of patients having class II malocclusion and was further divided into subgroups 2a) Class II with normal growth, 2b) Class II with vertical growth. Results: The results showed that the estimated marginal mean for upper pharyngeal width in class I malocclusion group was 8.56 mm, for class II malocclusion group was 7.80 mm, for normal growth individuals was 9.73 mm and that for vertical growth individuals was 6.63 mm. The estimated marginal mean for lower pharyngeal width in class I malocclusion group was 9.62 mm, in class II malocclusion group was 9.10 mm, in normal growth individuals was 8.95 mm and that in vertical growth individuals was 9.77 mm. The estimated marginal mean for pharyngeal area in class I malocclusion group is 330.13 sq.mm, in class II malocclusion group is 308.17 sq.mm, in normal growth individuals is 328.47sq.mm and that in vertical growth individuals is 309.83 sq.mm. Conclusions: The null hypothesis for this study, as per the statistical analysis, has been rejected.
