This is a study about the dynamics and effects of ultrasound guided maxillary nerve block in trigeminal neuralgia
Standard pharmacological treatment for trigeminal neuralgia is often insufficient. In this setting, patients often suffer trough everyday activities and quality of life is disturbed substantially. In this prospective clinical study, analgesic effect of ultrasound (US) guided maxillary nerve block will be investigated, in order to prolong pain-free time, reduce the use of standard analgesics, as well as atypical ones (e.g. antiepileptic drugs and antidepressants). Characteristics of US guided maxillary nerve block will pain investigated: reduction of pain (decrease of VAS score), duration of pain-free period, pain level during the procedure.

Pain level when anesthesia is applied
Pain will be graded according to visual analogue scale, 0 meaning no pain, 10 meaning the worse pain possible
