About

This is a study about the dynamics and effects of ultrasound guided maxillary nerve block in trigeminal neuralgia

Full description

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.

Sex: All

Ages: 18 to 85 years old

US block of maxillar nerve

Experimental group

Description:

Extraoral ultrasound-guided block of the maxillary nerve will be performed using an ultrasound device. After visualisation of the pterygomandibular space, of the maxillary artery and the mandibular nerve next to it, at a depth of 2-4 cm, the detection of the maxillary artery is confirmed by Color Doppler. A needle enters between the coronoid and condylar processes, using the "out of plane" technique, near the maxillary artery, and after negative aspiration, local anesthetic levobupivacaine (0,5%, 2 mL) combined with triamcinolonacetonid (2mL).

Treatment:

Procedure: US guided block of maxillary nerve
