“…25 The thickness of the masseter was more in the contracted state than in the relaxed state in all 3 groups bilaterally. This finding is similar to previous studies by Kiliaridis et al, 19 Raadsheer et al, 22 Kamala et al 12 During contraction, filaments of muscle slide actively towards the center of the sarcomere, resulting in shortening of the whole muscle. Muscle width increases during shortening.…”

“…The mouth opening of most of the patients (15 out of 18) in the present study ranged between 25 mm to 35mm. However, studies by Devathambi JR et al, 31 Kamala et al 12 reported a significant increase in masseter thickness in OSMF patients compared to the control group. Kant et al 32 reported decreased thickness of masseter muscle during advanced stages of OSMF.…”

“…This leads to hypertrophy of masticatory muscle. 12 Masseter muscle thickness has been measured by several investigators using various imaging techniques including computed tomography (CT) by Weijs and Hillen (1984), 13 Ultrasonography (USG) by Wilson and Crocker (1985), 14 and Magnetic Resonance Imaging (MRI) by Hannam and Wood (1989). 15 For the measurement of the masseter muscle, USG was proved to be superior to CT and MRI.…”

The benign increase in the size of the masseter muscle is referred to as masseter muscle hypertrophy (MMH). It may affect unilaterally or bilaterally. Frequent and prolonged chewing of areca nut, betel quid, and tobacco exerts undue pressure on muscles of mastication. This may lead to hypertrophy of masticatory muscles, especially the masseter. The objective of the study is to evaluate the difference in cross-sectional thickness of masseter muscle at rest and at maximum clenching position using USG in chronic areca nut/tobacco chewers, OSMF patients, and the control group.The study included 20 chronic areca nut/tobacco chewers and 18 OSMF consecutive patients. The control group comprised of 42 age, sex, and body mass index-matched healthy individuals. Ultrasonographic measurements were performed in all the subjects in both contracted and relaxed states. Intergroup comparison of ultrasonographic cross-sectional thickness was done using ANOVA with post hoc.Masseter muscle thickness significantly increased in chronic chewers in both relaxed & contracted states bilaterally when compared to OSMF & control group. Muscle thickness decreased in the OSMF group compared to controls. In patients with chronic chewing habits without OSMF, due to prolonged chewing muscle thickness increased whereas, in OSMF patients, reduction in mouth opening leads to a decrease in bite force and consequent atrophy of muscle.

BACKGROUND Oral submucous fibrosis (OSMF) is the most common precancerous lesion, prevalent mostly in South East Asia. The habit of betel nut or gutkha chewing is the main cause for this. There is a direct association between gutkha chewing habit and development of OSMF, the reason being exaggerated forces on the masseter muscle due to vigorous chewing for prolonged period of time. So, the present study was done to evaluate the thickness of masseter muscle in OSMF patients. METHODS A total of 25 subjects were included in the study from January 2015 to December 2017. 25 OSMF patients belonging to the age group of 25-50 years who attended the outpatient department of Veer Surendra Sai Medical College and Hospital, Burla, with masseteric hypertrophy and betelnut or gutkha chewing habit for more than 5 years, were included in the study. The computed tomography (CT) scans were obtained using Siemens Somatom Sensation 4-slice CT scanner. During the scanning period, the patients were asked to keep their mouth gently closed and relaxed. Axial sections of the CT scans were assessed for masseter muscles. The thickness of the muscle was calculated using image-analysing software and the measurements made were in millimeter (mm). Tabulation was done and statistical analysis was done using Mann-Whitney U test. RESULTS The thickness of masseter muscle of right side was found to be more than the left side in all patients except for one patient and the outcome was statistically significant with one tailed p value < 0.01. CONCLUSIONS The duration and frequency of the habit were found to be directly proportional to masseter muscle thickness and also with the clinical progression of the disease. Similarly, we also concluded from our study that there exists an association of masseter muscle hypertrophy with OSMF, and CT scan meas KEYWORDS OSMF, Masseter Muscle, CT Scan
