"Sinus headache" is a common chief complaint that often leads patients to an otolaryngologist's office. Because facial pain may or may not be sinogenic in origin, the otolaryngologist should be equipped to evaluate and treat or to appropriately refer these patients. Analysis of current data indicates that the majority of patients who present with sinus headaches actually have migraines. Furthermore, the downstream effect of the cytokine cascade initiated in migraine physiology can cause rhinologic symptoms, including rhinorrhea, congestion, and lacrimation, which may also confound diagnosis...

OBJECTIVE Intracranial aneurysms are vascular abnormalities associated with neurological morbidity and mortality due to risk of rupture. In addition, many aneurysm treatments have associated risk profiles that can preclude the prophylactic treatment of asymptomatic lesions. Gamma Knife radiosurgery (GKRS) is a standard treatment for trigeminal neuralgia, tumors, and arteriovenous malformations. Aneurysms associated with arteriovenous malformations have been noted to resolve after treatment of the malformation...

7.0Tesla(T) high-resolution diffusion tensor imaging (DTI) can supply information on changing microstructures in cranial nerves. We investigated DTI parameters and the feasibility of DTI criteria for diagnosing trigeminal neuralgia (TN). In this study, 14 patients (28 hemispheres) of mean age 49.0years (range, 31-64) with TN underwent DTI using 7.0TMRI. We compared fractional anisotropy (FA), axial diffusivity (AD), mean diffusivity (MD), and radial diffusivity (RD) of affected-side and unaffected-side trigeminal nerves using DTI...

Microvascular decompression (MVD) has been confirmed as an effective treatment of trigeminal neuralgia (TN); however, most previous reports just focused on MVD for TN caused by arterial conflict, there is a paucity of information about its use in venous compression causing TN. In the present study, the authors summarize 5-year experience of MVD for primary TN due to venous compression alone. Thirty-four patients with primary TN caused solely by veins underwent MVD. The presenting symptoms, key operative notes, surgical outcomes together with complications were reviewed...

BACKGROUND: Sphenopalatine ganglion is the largest collection of neurons in the calvarium outside of the brain. Over the past century, it has been a target for interventional treatment of head and facial pain due to its ease of access. Block, radiofrequency ablation, and neurostimulation have all been applied to treat a myriad of painful syndromes. Despite the routine use of these interventions, the literature supporting their use has not been systematically summarized. This systematic review aims to collect and summarize the level of evidence supporting the use of sphenopalatine ganglion block, radiofrequency ablation and neurostimulation...

Background: Trigeminal neuralgia (TN) is the most common cranial neuralgia in adults, with a slightly higher incidence in women than in men. This chronic pain condition affects the trigeminal nerve, also known as the 5th cranial nerve. It is one of the most deeply distributed nerves in the head. Antiseizure drugs are the main biomedical treatment of TN. However, TN is not the only source of facial pain. Background persistent idiopathic facial pain (PIFP) is also a chronic disorder, recurring daily for more than 2 hours per day over more than 3 months...

Perineural activity of a variety of inflammatory and immune system mediators can activate peripheral nerves leading to the perception of pain. One example of such effects includes the activity of interleukin 1 beta (IL-1β); this inflammatory mediator, upon binding to IL-1R1 neuronal membrane receptors will rapidly induce protein kinases in damage-sensing neurons, consequently altering heat-activated ionic inward currents leading to increased neuronal sensitivity to harmful heat. The ability to detect such mediators in proximity to sensory nerves is therefore crucial to investigating the contributing roles of inflammation in human chronic pain...

OBJECTIVE: Microvascular decompression (MVD) is an effective method for directly treating the etiology of trigeminal neuralgia (TGN). This study aims to investigate the factors that predict complete pain relief after MVD for treatment of TGN, and to study efficacy and safety in older patients. METHODS: This study was conducted in patients with TGN that were treated by MVD at Siriraj Hospital between 2004 and 2015. Cases with secondary TGN were excluded. Data was gathered from medical records, preoperative magnetic resonance imaging, intraoperative findings, and by telephone in patients lost to follow-up...

Background: Trigeminal neuralgia (TN) is a chronic pain condition characterized by brief episodes of lancinating pain in one or more distributions of the trigeminal nerve. Episodes of pain secondary to TN are triggered by certain stimuli, such as chewing, shaving, or touching the face. Although a common cause of TN is compression of the trigeminal nerve root entry zone by an artery or vein, many cases of TN are idiopathic. However, there have been limited reports in the literature of familial TN...

Trigeminal neuralgia (TN) is a chronic neuropathic pain disorder characterized by intense, lancinating attacks of facial pain. Increasing evidence suggests that TN is accompanied by abnormalities in brain morphology, white matter microstructure and function. However, whether these abnormalities are linked or reflect independent etiologies remains unknown. Using multimodal magnetic resonance imaging data of 20 TN patients and 21 healthy controls (HC), we investigated cortical gyrification abnormalities, their relationships with abnormalities of the underlying white matter microstructure and gray matter morphology, as well as their functional significance in TN...
