The role of soft tissue mobilization in reducing orofacial and general complaints in a patient with Kimmerle anomaly and temporomandibular joint disorder: A case report.

Background

Kimmerle anomaly belongs to the anatomic varieties of the first cervical vertebra. The clinical pattern is dominated by vascular- and neurogenic-type headaches, dizziness, decreased postural muscle tension, and vegetative symptoms. Clinical Presentation: A 37-year-old woman who suffered from headache and pain in the left temporomandibular joint underwent clinical examination, electromyography of masticatory muscles, temporomandibular joint vibration analysis, cone beam computed tomography, and soft tissue mobilization. Radiologic examination revealed Kimmerle anomaly on the right side of the atlas. Clinical Relevance: Myofascial release decreased the tension within anatomic structures projected to the vertebral artery groove. Better movements of the cervical spine and fewer headaches were noted. Increased cervical and masseter muscle tension were considered the main cause of the ailments. The proprioceptive system of the cervical spine was accepted as a reason for persistent headaches. Soft tissue mobilization revealed positive healing effect in the patient with temporomandibular joint disorder and Kimmerle anomaly.
