The development of modern maxillofacial surgery and surgical dentistry is impossible without improving the methods of diagnosis and treatment. Today, the diagnosis, treatment and rehabilitation of patients with trauma to the lower jaw remains an urgent problem. The purpose of this study is to study the functional state of the masticatory muscles during osteosynthesis of the lower jaw in the region of the branch and articular process in the traditional way, as well as using endoscopic technologies. An analysis of 82 case histories was carried out. The patients were divided into 2 groups: 42 patients were included in the control group - surgical intervention of the lower jaw in the region of the branch and articular process was performed in the traditional way; 40 patients were included in the main group - the treatment of a fracture of the lower jaw of the above localizations was carried out using endoscopic technologies. Patients of both groups underwent a functional study of masticatory muscles. It was found that the normalization of the average amplitude of the temporal and masticatory muscles in patients of the main group normalizes much earlier than in patients of the control group.
