In the present case, a branching tributary of the occipital artery at the crossing point forming a constricting loop above the course of the GON was found to be the cause of entrapment. [ncbi.nlm.nih.gov]

Diagnostic workup including magnetic resonance imaging of brain and computerized tomography of the sinuses are usually negative, but there have been few cases of a nasal contact point. [ncbi.nlm.nih.gov]

Key points • For several cranial neuralgias, the diagnostic workup should include structural imaging with MRI with and without contrast to evaluate for evidence of inflammation or space-taking lesions, vascular imaging consisting of either MRA or CTA [medlink.com]

See Workup for more detail. [emedicine.medscape.com]

Diagnosis and treatment can be challenging. Based on a case report and literature review, disease aspects and treatment options including laparoscopic (triple) neurectomy are discussed. [ncbi.nlm.nih.gov]

It was managed by several medication and landmark-based great auricular nerve block with poor prognosis. PATIENT CONCERNS: A 25-year-old man presented with a pain in the left lateral neck and auricle. [ncbi.nlm.nih.gov]

Prognosis Some individuals recover from an initial attack and never have another. Others will experience clusters of attacks followed by periods of short or long remission. [ninds.nih.gov]

Patients aged 60 years had the worst prognosis: 18% still had mild pain at 3 months and 6% had moderate or severe pain. At 1 year, 8% had mild pain and 2% had moderate pain. [mdedge.com]

Prognosis The condition tends to come and go. Attacks of pain may be experienced off and on all day, or for days or weeks at a time, or no pain may be experienced for a prolonged period of time. However in most cases, the prognosis is good. [brainfoundation.org.au]

Direct injury to the nerve appears to be the etiology of post-traumatic external nasal neuralgia. [ncbi.nlm.nih.gov]

In about 85% of cases, no lesion is identified, even after extensive investigations, and the etiology is labeled idiopathic (classic) by default. [emedicine.com]

In a retrospective epidemiological study [ 5 ], among all cases between 1945 and 1984, glossopharyngeal neuralgia had an incidence of 0.7 cases per 100,000 patients [ 5 ], while an epidemiological study conducted at the Mayo Clinic between 1922 and 1977 [karger.com]

A case report of trigeminal neuralgia in a patient with spontaneous intracranial hypotension has been reported; both conditions resolved following surgical treatment of a cervical root sleeve dural defect. [3] Epidemiology Frequency Trigeminal neuralgia [emedicine.com]

Summary Epidemiology The estimated prevalence in France is 1/6000. Clinical description The disease usually presents between the ages of 50-70 years, with an insidious onset of symptoms. [orpha.net]

We describe current approaches to the diagnosis and assessment of neuropathic pain and discuss the results of recent research on its pathophysiologic mechanisms. [ncbi.nlm.nih.gov]

Pathophysiological Basis of Surgical Treatment The pathophysiological basis of the surgical treatment relies on our knowledge about the pathophysiology of trigeminal neuralgia. [omicsonline.org]

Data on surgical procedures, incidence, cause of PON, management, outcomes, and preventive technique were extracted. [ncbi.nlm.nih.gov]
