Oral submucous fibrosis (OSMF) is a chronic insidious disease affecting mucosa and submucosa of oral cavity and soft palate. The present study aimed to evaluate the morphology of soft palate in normal individuals and OSMF patients using lateral cephalometry and to compare and correlate these variants of soft palate with different stages of OSMF. 100 subjects were included in the study, who were divided into two groups. Group I included 50 subjects with clinical diagnosis of OSMF and Group II included 50 normal subjects (control group). Using digital lateral cephalometry, velar length and width were measured and soft palatal patterns were categorized based on You et al.’s classification. Leaf and rat-tail patterns of soft palate were predominant in control group, whereas butt and crook shaped variants were more in study group. Anteroposterior (A-P) length of soft palate was significantly greater in stage I OSMF, while superoinferior (S-I) width was greater in stage III OSMF. Interestingly, a negative correlation was observed in staging of OSMF and A-P dimensions. As the staging of OSMF advances, the A-P length of soft palate decreases, but S-I width increases.
