[Clinical picture and treatment of bilateral facial pain in lesions of the trigeminal nerve system].

A total of 104 patients with bilateral facial pain were examined at a specialized neurostomatological department. The authors analyze the main mechanisms of the development of bilateral facial pain in patients with an impaired system of the trigeminal nerve (trigeminal neuralgias, dental plexalgia, syndrome of the nosociliary nerve), as well as the characteristics of their clinical manifestations. A classification of bilateral prosopalgias is proposed. The criteria of their diagnosis with the use of clinical and electrophysiological methods of examination (EEG, REG, EMG, electrothermometry, esthesiometry, electrical excitability of the exit sites of the trigeminal nerve branches and radioisotopic examination of the muscular blood flow in the face with the help of 133Xe) are also presented. The main principles of the treatment of bilateral prosopalgias are outlined.
