Analgesic Effect of Ultrasound Guided Maxillary Nerve Block in Trigeminal Neuralgia

Analgesic Effect Evaluation of Ultrasound Guided Maxillary Nerve Block in Trigeminal Neuralgia

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.

Inclusion Criteria:

• patients with trigeminal neuralgia

Exclusion Criteria:

• allergy to local anesthetics
• local infection at the site of needle puncture
• parotitis
• serious liver disease
• use of antiarrhythmics group III (eg amiodarone)
• anticoagulant or antithrombotic drugs
