Clinical and Neurological Peculiarities of Trigeminal Neuralgia

Trigeminal neuralgia (TN) is characterized by sudden, severe, brief, and stabbing recurrent episodes of facial pain in one or more branches of the trigeminal nerve. The right side of the face (60%) is affected more than the left side. Bilateral simultaneous pain in TN is rare (1.7%–5%) and more often these patients experience side-alternating unilateral pain paroxysms. The pain of TN most frequently affects the distribution of the maxillary (V2) and mandibular (V3) divisions of the trigeminal nerve, though approximately a quarter of the cases have ophthalmic (V1) division involvement. The results of the study are presented and the frequency of damage to the branches of the trigeminal nerve, the most common etiological factors in the development of TN in the examined patients, the frequency of damage to the branches of the trigeminal nerve depending on the duration of the disease, the clinical semiology of the trigeminal nerve depending on the duration of the disease, the score of pain in TN in depending on the duration of the disease, clinical and vegetative indicators depending on the duration of TN.
