Introduction: Temporomandibular disorder is a collective term used to describe a a number of related disorders affecting the TMJ, muscles of mastication and associated structures all of which have common symptoms like pain and reduced jaw opening. Most of the studies on temporomandibular disorders in literature are related to malocclusion teeth and orthodontic treatment. In literature the role of “Neurologic” and “Otologic” symptoms have been researched in isolations. There is a need to co-relate these findings with the severity of temporomandibular disorders in patients seeking orthodontic treatment. Objectives: To evaluate and compare Neurologic symptoms, Otologic symptoms and its correlation with the proximity of TMJ disk and condyle in mild, moderate and severe Class II(vertical)TMD cases. Methodology: Grading of TMD using Helkimo and Craniomandibular index and evaluation of Neurologic and Otologic symptoms by separate questionnaires and its correlation with the proximity of TMJ disk and condyle using MRI. Expected results: Degree of association of Neurologic and Otologic symptoms with TMD. Conclusion: Temporomandibular disorders can be diagnosed by assessing the extra- craniofacial symptoms like Neurologic and Otologic symptoms and may help in early diagnosis and evaluating the potential risk factors for developing temporomandibular disorders. Hence a study is planned in the department.
