Prolonged blockade of the cervical sympathetic nerve by stellate ganglion block accelerates therapeutic efficacy in trigeminal neuropathy.

Purpose: Stellate ganglion block (SGB) is effective in treating head and neck pain and neuropathic diseases by increasing tissue blood flow through its sympatholytic effect. This study aimed to investigate the relationship between duration of cervical sympathetic nerve block by SGB and its therapeutic efficacy against trigeminal neuropathy after orthognathic surgery.

Methods: Twenty-eight patients with trigeminal neuropathy were randomly assigned to two groups (mepivacaine and levobupivacaine) according to the drug used for SGB.

Pain Relief in Short-Lasting Unilateral Neuralgiform Headache with Conjunctival inJection and Tearing Syndrome with Intravenous Ketamine: A Case Report.

Purpose: Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a rare form of primary headache, classified as trigeminal autonomic cephalalgia. Since the underlying mechanism of the pathogenesis has not yet been determined, a standardized therapeutic strategy for SUNCT is unavailable. We present a case of SUNCT syndrome with successful pain relief by intravenous administration of ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist.

A Nasal High-Flow System Prevents Upper Airway Obstruction and Hypoxia in Pediatric Dental Patients Under Intravenous Sedation.

Purpose: Upper airway obstruction (UAO) and oxygen desaturation are risk factors for major complications of intravenous sedation (IVS) in pediatric dental patients. This study aimed to investigate the use of a nasal high-flow (NHF) system for the prevention of UAO and oxygen desaturation in pediatric dental patients under IVS.

Methods: The authors implemented a prospective randomized design.

Effects of stellate ganglion block on postoperative trigeminal neuropathy after dental surgery: a propensity score matching analysis.

This study aimed to evaluate the effects of stellate ganglion block (SGB) on postoperative trigeminal neuropathy (TNP) after dental surgery. This was a retrospective study based on the medical records of all patients with postoperative TNP at Kyushu Dental University Hospital from 2014 to 2019. Patients were divided into the SGB group (received SGB) and non-SGB group (did not receive SGB).

Predicting the therapeutic effect of carbamazepine in trigeminal neuralgia by analysis of neurovascular compression utilizing magnetic resonance cisternography.

The aim of this study was to determine whether the evaluation of neurovascular compression (NVC) using new criteria on magnetic resonance (MR) cisternography improves the prediction of the curative effects of carbamazepine (CBZ) in trigeminal neuralgia (TN). In this study, a new analysis of NVC using MR cisternography was performed retrospectively for 280 patients with clinical signs and symptoms suggesting TN. The new analysis examined whether the site of the NVC was less than 3mm from the edge of the exit point and within the first third of the root entry zone on MR cisternography.
