Abstract

Objectives: Evaluation the treatment results of low-dose trigeminal nerve block with alcohol in idiopathic trigeminal neuralgia patients and some factor associations. Subjects and methods:  Longitudinal and retrospective study in 38 idiopathic trigeminal neuralgia patients with low-dose trigeminal nerve block with alcohol from January 2019 to July  2022. Results: 38 patients were analyzed who received absolute alcohol injections in the management of trigeminal neuralgia (TN) from January 2019 to July 2022. There are 30 cases were injected with 0,3 ml of absolute alcohol and 8 cases with a greater 0,3 ml dose. The visual analogue scale (VAS) was used for pain improved with moderate level (18 cases) and severe level (12 cases) before, 24 patients had marked improvement of pain with mild level or free from pain. 30 patients (100%) who initially became free from pain experienced a recurrence of pain at least 1 year. Using the Barrow Neurologic Institude pain scale (BNI-PS), after 2 weeks there were only 2 patients (6,7%) experienced recurrent pain with BNI-PS IV, 2 patients (6,7%) with BNI-PS IV after 12 months and 5 patient (17,2%) with BNI-PS IV, 1 patient with BNI-PS V (3,4%) after more than 12 months. No serious complications were reported. Loss of sensation along the branch involved in TN or facial numbness was reported in 87% cases with 0,3 ml of absolute alcohol and 87,5% cases with a greater 0,3 ml dose. Other complications included: keratitis in 12,5% cases with 0,3 ml of absolute alcohol and 13,3% cases with a greater 0,3 ml dose, masseter muscle weakness in 23,3% cases with 0,3 ml of absolute alcohol and 25% cases with a greater 0,3 ml dose.
