Temporomandibular joint dysfunction is a term that encompasses a number of clinical manifestations related to the pathology of the TMJ and masticatory muscles. The most common sign or symptom is pain in the temporomandibular joint, limited range of mouth opening, and noise phenomena in the TMJ (clicks, crunching). Materials and methods: The diagnosis of the temporomandibular joint and the cervical spine was performed using clinical (study of occlusion), radiation – magnetic resonance imaging (MRI), radiography of the cervical spine; neurophysiological – electromyography (EMG), stimulation electromyography (SEM), needle electromyography (IEMG); ultrasound diagnostics of muscles (ultrasound) methods The studies were conducted in 60 patients who were divided into groups. The first group (n = 20) included patients with temporomandibular joint dysfunction without pathologies of the cervical spine. The second group (n = 20) consisted of patients with temporomandibular joint dysfunction and pathology of the cervical spine. The third group (control) (n = 20) was formed from patients without pathology of the temporomandibular joint and cervical spine. Results: According to neurophysiological studies, it was found that patients in the second group had statistically significant differences in the studied parameters “Amplitude”, “Latency”, and “Spontaneous activity” in the studied muscles (p 0,001). The incidence of structural changes in the masticatory muscles according to ultrasound diagnostics was also higher in the second group. Conclusions: Dysfunction of the temporomandibular joint is associated with pathology of the cervical spine.
