Evaluation of oral submucous fibrosis using ultrasonographic technique: A new diagnostic tool

Objectives:To evaluate the efficacy of ultrasonography (USG) as a non-invasive tool in assessing the severity of oral submucous fibrosis (OSMF) and also to assess the relationship between OSMF and hypertrophy of the masseter muscle.Materials and Methods:The submucosal thickness in buccal mucosa and masseteric muscle hypertrophy were measured using ultrasound (10-15 MHz) in 60 patients comprising 30 OSMF patients and 30 controls.Results:Results were analyzed by one way analysis of variance, Chi-square test and t-test. As the stages of OSMF advanced there was an increase in submucosal thickness of the buccal mucosa as well as masseter muscle thickness in both relaxed and contracted state in the study group when compared with controls (P < 0.005).Conclusion:USG is an effective non-invasive zero radiation tool for assessing the progression of OSMF.

“…18 To document the specific ultrasonographic findings in OSF, we excluded patients with other systemic diseases and oral mucosal lesions, since fibrosis results in a non-specific increase in echogenicity of tissues, irrespective of the cause. 10 Although an intraoral approach has been described in some studies, 14 we preferred transcutaneous ultrasonography because OSF is a disease that causes restriction of mouth opening, hence it may not have been feasible to place a relatively large endocavitary transducer intraorally in all the cases. The normal echo architecture of the layers of the cheek from the skin to the mucosa, as determined by transcutaneous ultrasonography in our study, was consistent with that described in earlier studies.…”

“…Despite these facts, very few studies have reported the use of ultrasonography in the evaluation of OSF. 13,14 It is with this background that we chose to undertake this preliminary study on ultrasonographic evaluation of OSF to characterize the sonographic features of the buccal mucosa in OSF patients, compared with normal individuals and habitual areca chewers without oral lesions.…”

Objectives: To characterize the sonographic features of the buccal mucosa in patients with oral submucous fibrosis (OSF). Methods: Three groups (controls with areca-related habits, controls without areca-related habits and clinically diagnosed OSF cases), each comprising 30 subjects, were included in the study. After a thorough clinical examination, transcutaneous B-mode ultrasonography was performed with a multifrequency linear transducer (5-10 MHz) for anterior and posterior buccal mucosa bilaterally. Both clinical and ultrasound findings were recorded by three independent observers. One-way analysis of variance and Tukey's honestly significant difference post-hoc tests were used for statistical comparisons between groups and Pearson x 2 tests to compare the proportions. Kappa statistics was used to determine the interobserver agreement. Results: The submucosa that appeared hypoechoic in the control groups had significantly increased echogenicity in the case group (hypo-to isoechoic in 46.7% and isoechoic in 53.3%). The differentiation between the submucosa and the muscle layer appeared distinct in the control groups while it was not clear in the case group (indistinct in 50% and completely lost in 50%). The number of sites found positive on the ultrasound was significantly greater than the number of clinically positive sites. There was a very good interobserver consistency in clinical and ultrasound findings. Conclusions: Ultrasonography of the buccal mucosa demonstrates increased submucosal echogenicity and reduced echo differentiation between submucosa and muscle layer in OSF cases. Hence, it can be used as a non-invasive imaging modality to assess the disease extent and severity across the entire buccal mucosa to supplement clinical evaluation.

[28] Masticatory muscle hypertrophy is also seen in OSMF patients who can be assessed with US.

The story of the application of ultrasound (US) in imaging goes back a long way in history. It has been deemed useful in various situations and has evolved over time to a more sophisticated and precise modality. Some of the advances are in the form of newer and more useful equipment increasing its pertinence in dentistry and medicine. Currently, it is being used in various head and neck pathologies owing to its non-invasive nature and has gained wider acceptance in maxillofacial imaging. In this paper we will take a relook of US in areas such as its history, basic principles, advances in the equipment and wide array of applications in head and neck pathologies and also weigh its merits and demerits in specific areas.
