Objective: Temporomandibular disorder (TMD) is multifactorial in nature and hence one of the most challenging diseases of modern society. The lateral pterygoid muscle (LPM) has been implicated in TMD, i.e. it may become hyperactive, eventually leading to anterior and medial disc displacement. It has been hypothesized that the hyperactivity of LPM can cause asymmetry of the lateral pterygoid plate (LPP). Hence, the present study was undertaken to evaluate a potential relationship between LPP measurements and Internal Derangements of temporomandibular joint (TMJ), using cone-beam computed tomography (CBCT).
Materials and Methods: CBCT images of 20 patients with Internal Derangement of TMJ were evaluated and compared with images of 20 age- and gender-matched controls, without any TMJ disorders. The length of LPP was measured in the axial view of the full skull CBCT images.
Results: The LPP measurements in patients from the study group were increased compared to the control group. Further, in females, the mean LPP length on left side was significantly increased in the study group compared to the control group.
Conclusion: From the results of the present study, we can suggest that evaluating the LPP asymmetry in TMD patients using CBCT could be useful for its diagnosis. However, further studies with larger sample size are recommended in this direction.
