Today, trigeminal neuralgia (NTN) is considered one of the most common prosopalgias and is a typical example of neuropathic pain of a paroxysmal nature. According to various literature sources, trigeminal neuralgia (TN) occurs with a frequency of 4-13 cases per 100,000 population. HTN is manifested by very painful and excruciating facial pain and is one of the most persistent pain syndromes. This type of facial pain often has a recurrent or chronic course and is very difficult to treat compared to other types of facial pain. Therefore, trigeminal neuralgia has a negative impact on the quality of life of patients, leading them to disability[1]. Today, trigeminal prosopalgia is a chronic disease that manifests itself as intense, burning, shooting neuralgia in the area of innervation of one or more branches of the trigeminal nerve. The aim of our study was to study the technique of neuroimaging in trigeminal prosopalgia, as well as to study the conservative and surgical method of treatment – method P.Janetta, a method of radiofrequency ablation and percutaneous selective rhizotomy with alcohol, a method of microcompression with a balloon, a method of stereotactic radiosurgery using a Gamma knife.
