Aim: To investigate the association between various morphological types of soft palate and skeletal Class I and Class II malocclusions using cone beam computed tomography. Materials and Method: Pre-treatment CBCT of the 80 patients are taken, they are categorized into two groups: skeletal Class I (ANB 0°–4°), skeletal Class II (ANB > 4°). The Morphological variants of soft palate were assessed and were allotted to one of the six patterns described by You et al using NNT software. Results: Comparison between the type of malocclusion and the frequency of shapes of soft Palate revealed that Type I (leaf‑shaped) soft palate (40%), was observed more significantly (P<0.05) among skeletal Class I malocclusion, Type II,(rat tail shaped) soft palate (67.5%), was most frequently found in skeletal Class II malocclusion. Conclusion: Type 2 Rat tail shaped soft palate is the most common shape of soft palate. There is a significant correlation between the variants of soft palate and the type of Skeletal Malocclusion.
