Pulsed radiofrequency is an effective, safe, and nondestructive pain treatment technique that has been insufficiently reported in the treatment of supraorbital neuralgia. We report the successful use of pulsed radiofrequency to alleviate acute severe supraorbital neuralgia in a post-craniotomy patient. A 52-year-old female, who had acute severe supraorbital neuralgia after having received a right frontal craniotomy and with poor efficacy in response to medication and a nerve block, was subjected to ultrasound-guided pulsed radiofrequency treatment and experienced complete pain relief, as a result of which the patient stopped taking all analgesic drugs.

Objective: After medication failure, patients with refractory trigeminal neuralgia (TGN) often present urgently and seek more potent or invasive therapies such as opioids or surgical options. Peripheral nerve blocks, safe and simple, may offer extended pain relief prior to opioid use or more invasive ganglion level procedures.

Methods: We report a retrospective case-series (urgent care, at a large urban medical center, over a 2 year period) of nine patients with intractable primary TGN who underwent peripheral trigeminal nerve blocks after failing conservative medical therapy. Read More

Orofacial myofascial pain is prevalent and most often results from entrapment of branches of the trigeminal nerves. It is challenging to inject branches of the trigeminal nerve, a large portion of which are shielded by the facial bones. Bony landmarks of the cranium serve as important guides for palpation-guided injections and can be delineated using ultrasound. Read More

Significant variations exist in the occurrence, form, and position of supraorbital nerve exits through the frontal bone. Detailed knowledge of the positional variations of supraorbital exits is important to ensure safe and successful regional anesthesia, and to avoid iatrogenic nerve injuries during surgery of the orbitofacial region. Supraorbital nerve exits from 116 sides of 58 dry intact adult skulls (37 male and 21 female) in a Sri Lankan population were examined to determine the morphological features and the precise position in relation to the facial midline, temporal crest of frontal bone, and frontozygomatic suture.

Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a rare, primary headache syndrome, which is classified as a subtype of trigeminal autonomic cephalalgias. Although SUNCT is usually refractory to treatment, several antiepileptic drugs have recently shown promising results for its treatment. However, there is a lack of evidence regarding the course of SUNCT during pregnancy and the available treatment options. Read More

When choosing an infiltrative anesthetic agent, the type of procedure, the length of time required for anesthesia, and the pharmacodynamics of each medication are important considerations. Distraction techniques and buffering with sodium bicarbonate can be used to decrease the pain associated with injection. Local cutaneous infiltration is the most commonly used anesthetic technique and involves direct injection into the area requiring anesthesia. Read More

Bright light can cause excessive visual discomfort, referred to as photophobia. The precise mechanisms linking luminance to the trigeminal nociceptive system supposed to mediate this discomfort are not known. To address this issue in healthy human subjects we modulated differentially visual cortex activity by repetitive transcranial magnetic stimulation (rTMS) or flash light stimulation, and studied the effect on supraorbital pain thresholds and the nociceptive-specific blink reflex (nBR).

Monoamines have an important role in neural plasticity, a key factor in cortical pain processing that promotes changes in neuronal network connectivity. Monoamine oxidase type A (MAOA) is an enzyme that, due to its modulating role in monoaminergic activity, could play a role in cortical pain processing. The X-linked MAOA gene is characterized by an allelic variant of length, the MAOA upstream Variable Number Tandem Repeat (MAOA-uVNTR) region polymorphism. Read More

Background: Nerve blockades are used for the treatment of acute migraine episodes in emergency room conditions and beneficial results are obtained from this clinical use. Although this is the case, there are limited numbers of studies investigating the long-term effects of such an approach.

Patients And Methods: In this investigation, we had 26 patients diagnosed as migraine based on the ICHD II criteria, these were injected with 1% lidocaine at supraorbital and infraorbital nerve localizations and clinical results were evaluated after 6 months of follow-up. Read More

Mount Sinai School of Medicine.

Background: Patients undergoing stereotactic headframe placement for radiosurgery report that discomfort associated with the headframe often lasts for the duration of the treatment day (approximately 6 hours). We hypothesize that blockade of scalp nerves prior to headframe placement reduces the incidence of moderate to severe head pain during the entire treatment day. We describe a randomized, double-blind, placebo-controlled study of awake patients having radiosurgery for intracranial pathology that examines whether scalp nerve blockade and local anesthetic infiltration results in superior patient comfort versus infiltration alone.

Unlabelled: Cortical pain processing is associated with large-scale changes in neuronal connectivity, resulting from neural plasticity phenomena of which brain-derived neurotrophic factor (BDNF) is a central driver. The common single nucleotide polymorphism Val66Met is associated with reduced BDNF activity. Using the trigeminal pain-related evoked potential (tPREP) to repeated electrical painful stimuli, we investigated whether the methionine substitution at codon 66 of the BDNF gene was associated with changes in cortical processing of noxious stimuli.

Knowledge of the location of foramina in the maxillo-facial region is necessary in clinical situations requiring regional nerve blocks and in open as well as endoscopic surgical procedures to avoid injury to corresponding nerves. In this study, measurements were taken on 79 adult dried human skulls to determine the position of the supraorbital, infraorbital, and mental foramina. Supraorbital foramina were found to be approximately 25 mm lateral to the midline, 30 mm medial to the temporal crest of the frontal bone, and 2-3 mm superior to the supraorbital rim. Read More

Object: Stable hemodynamics, normocapnia, and adequate pain relief are considered important factors in the reduction of neurological complications in pediatric patients undergoing encephaloduroarteriomyosynangiosis (EDAMS) operations for the treatment of moyamoya disease. A preoperative skull block may reduce hemodynamic fluctuations and hypo- or hyperventilation due to emergence delirium or oversedation and provide adequate pain relief, thereby reducing postoperative morbidity.

Methods: Pediatric patients (age 3-13 years) undergoing EDAMS surgery for moyamoya disease were randomly divided into a nerve block (NB) group (18 cases) or control group (21 cases). Read More
