Correlation of ultrasonographic measurements, histopathological grading, and clinical staging in oral submucous fibrosis.

AIMS AND OBJECTIVES: To evaluate the presence and thickness of submucosal fibrosis in oral submucous fibrosis (OSMF) patients ultrasonographically and to correlate these findings with the clinical stage and histological grade of OSMF.

MATERIALS AND METHODS: Forty participants (twenty cases and twenty controls) were included in the study. The patients diagnosed clinically as having OSMF and consented for biopsy were included in the cases, and completely healthy individuals with no habit history or oral lesions were included in the control group after matching the body mass index. After clinically staging, the patients' transcutaneous ultrasonography (USG) was performed and after that punch biopsy was taken and the specimen was graded histopathologically.

RESULTS: The data were statistically analyzed using Mann-Whitney test and Spearman's rank correlation. The cases showed increased submucosal thickness as compared to the controls. The USG measurements statistically correlated with the clinical stage and histopathological grade of OSMF.

CONCLUSION: USG proves to be a valuable adjunctive modality in diagnosing, staging and also evaluating the prognosis of OSMF.
