Trigeminal neuralgia (TN) is a common pain syndrome. The classic form (Type 1) is characterized by sudden onset of extreme, sporadic, burning or shock-like facial pain that is temporary or episodic [1]. The atypical form (Type 2), is characterized by constant aching, burning, stabbing pain of somewhat lower intensity than Type 1. The intensity of pain can be physically and mentally incapacitati...

statement of the problem: trigeminal neuralgia (tn) presents with a shooting pain in maxillofacial region which compels the involved patients to visit many medical and dental physicians to relieve the pain. hence, assessing the outcomes of different treatment modalities may help the patients and their clinicians choose a suitable practical method of treatment.  purpose: the study was aimed to e...

OBJECTIVES To investigate the clinical characteristics of patients with trigeminal neuralgia referred to surgery in a center of reference. METHODS We evaluated the general characteristics of 395 patients with trigeminal neuralgia referred to neurosurgery as treatment. They corresponded to 2 samples of 1984 and 2004. The EDOF-HC protocol (Orofacial Pain Questionnaire) and the medical profile w...

INTRODUCTION The use of intraoperative CT-guidance during the percutaneous treatment of trigeminal neuralgia has become increasingly popular due to the greater ease of foramen ovale cannulation and decreased procedure times. Concerns regarding radiation dose to the patient, however, remain unaddressed. We sought to compare the emitted radiation dose from fluoroscopy with intraoperative CT for t...

BACKGROUND Rhabdomyomatous mesenchymal hamartoma (RMH) is a benign, potentially pigmented lesion that occurs in the head and neck region. It generally consists of haphazardly arranged skeletal muscle with adipose tissue, blood vessels, collagen and nerve fibers and is largely asymptomatic. Trigeminal neuralgia is pain due to compression of the trigeminal nerve. TN may be idiopathic or associate...

Trigeminal neuralgia is a facial pain syndrome that occurs repeatedly and chronically on one side of the face following distribution trigeminal nerve branches. estimated to be around 0.16%-0.3%, with an incidence rate 4-29 people per 100,000 people/year, higher in women than men (ratio 3:2). The increases age. causes are divided into two types, classic symptomatic. main mechanism compression by...

The trigeminal neuralgia caused by neurovascular compression is a neurosurgical pathology requiring the preoperative identification as exact as possible of the neurovascular conflict. In this case, neuroimaging is very useful, as it allows not only the determination of the neurovascular conflict of the trigeminal nerve, but also the correct indication of an adequate surgical approach.

A case of an extremely healthy, active, 96-year-old patient, nonsmoker, is reviewed. He was initially treated for left V1, V2, and V3 trigeminal neuralgia in 2001, at age 80, with stereotactic radiosurgery (SRS) with a dose of 80 Gy to the left retrogasserian trigeminal nerve. He remained asymptomatic for nine years until his trigeminal pain recurred in 2010. He was first treated medically but ...

Approximately 6 to 16% of patients with trigeminal neuralgia symptoms present intracranial tumors, the most common being the vestibular schwannoma (acoustic neuroma). Some symptoms reported by patients include hearing loss, tinnitus, headaches, vertigo and trigeminal disturbances. An increased muscle response in the surrounding head and neck musculature may also be observed, which mimics signs ...

BACKGROUND Trigeminal neuralgia is accompanied by severe mechanical, thermal and chemical hypersensitivity of the orofacial area innervated by neurons of trigeminal ganglion (TG). We examined the role of the voltage-gated sodium channel subtype Nav1.9 in the development of trigeminal neuralgia. RESULTS We found that Nav1.9 is required for the development of both thermal and mechanical hyperse...
