Trigeminal Neuralgia (Facial Pain)
Markers for Pain ResearchTrigeminal Neuralgia is a progress chronic condition. Dysfunctional trigeminal signaling can lead to intense, searing facial pain. It is caused by pressure on the trigeminal nerve.The root causes of the condition are not well understood. Ourpain research markers have been widely used and frequently published through the years and have been important contributors to our growth, Here's a recent pub referencing use of one ourP2X3 Antibodies-Momoko Koizumi, Sayaka Asano, Akihiko Furukawa, Yoshinori Hayashi, Suzuro Hitomi, Ikuko Shibuta, Katsuhiko Hayashi, Fusao Kato, Koichi Iwata, and Masamichi Shinoda.

ConclusionOur findings suggest that optical motor cortex stimulation can alleviate pain behaviors in a rat model of trigeminal neuropathic pain. Transmission of trigeminal pain signals can be modulated via knock-down of α-CGRP and optical motor cortex stimulation.
Authors: Vesper J, Santos Piedade G, Hoyer R, Slotty PJ Abstract Neuropathic facial pain is notoriously difficult to treat, regardless of its origin and duration. Since the first reported sphenopalatine ganglion blockade by Sluder in 1908, this ganglion has assumed an important role among the structures targeted for the treatment of facial pain. Recent years have witnessed the rise of neuromodulation over ablative procedures, including the development of an implantable stimulation device specially designed for use in the pterygopalatine fossa. Sphenopalatine ganglion stimulation has been demonstrated as effective a...
We report four cases of effective analgesia for intractable secondary headache resistant to medical management with high thoracic ESP blocks. In each case, the ESP block provided instant pain relief. We suggest that the findings of this case series indicate that the ESP block may be a useful intervention in patients with severe secondary headache or posterior cervical pain where conventional therapies have limited success, though more studies are necessary.

Conclusions: Concomitant use of bilateral SPG block with general anesthesia is an effective and safe alternative technique to scalp blockade for obtundation of hemodynamic responses due to noxious stimulus during craniotomy surgeries.
ConclusionsThese data demonstrates the possibility of sensitization of vestibular nucleus neurons to impair vestibular function after CM, and anti-CGRP treatment to restore vestibular dysfunction in patients with CM.
Conclusions: CT-guided low-temperature plasma radiofrequency ablation is an effective and safe strategy for refractory cluster headache. For patients who have not responded to conservative treatment, this minimally invasive intervention is a reliable alternative. PMID: 32489492 [PubMed]
Purpose of review Cluster headache is a neurological disorder that patients consider the most severe pain they experience. Recognizing new treatments provides opportunities to advance current management. Recent findings In contrast to the classic treatments, new options narrow in on the therapeutic target and are better tolerated. Calcitonin gene-related peptide (CGRP) pathway blockade with monoclonal antibodies (MABs), specifically the CGRP MAB galcanezumab, represents an important advance for episodic cluster headache, reducing the number of attacks during a bout. Neuromodulation strategies aimed at anatomical struc...
Rationale: Migraine is a recurrent, disabling neurovascular headache disorder. The patient's quality of life can be severely impaired by migraine attacks. Stellate ganglion block (SGB) can be used to relieve pain in the head, neck, and upper extremities. In the present cases, we performed SGB in 2 patients with migraine that responds poorly to drugs. Patient concerns: Patients 1 and 2 suffered from chronic, bilateral pulsating headache, accompanied by nausea and vomiting. Patient 1 presented with headache of 8 on the visual analog scale (VAS), and 37 on the migraine disability assessment (MIDAS). Patient 2 reported he...
CONCLUSIONS: In our small series of patients with refractory chronic SUNCT/SUNA, SPG-PRF was a safe and effective treatment modality. The potential reproducible positive effect of subsequent treatments may prevent or delay the use of more invasive and costly interventions for at least a proportion of these patients.
