A new topical treatment for acute herpetic neuralgia and post-herpetic neuralgia: the aspirin/diethyl ether mixture. An open-label study plus a double-blind controlled clinical trial.

Topical aspirin/diethyl ether (ADE) mixture was used to treat 45 consecutive patients with acute herpetic neuralgia (AHN) (n = 28) and with post-herpetic neuralgia (PHN) (n = 17) in an open-label study. Good-to-excellent results were achieved by 93% of AHN patients and by 65% of PHN patients. Earlier treatment yielded better results for the AHN but not the PHN group. The topical treatment seemed to accelerate the healing of acute herpetic skin lesions and possibly modulate the severity of the herpetic infection. Furthermore, a striking reduction in the percentage of AHN patients developing PHN was observed in the treated group, as compared with the disease natural history reported in the literature (4 vs. 50-70%). Treatment tolerance was excellent with no adverse effect observed. In addition to the open trial, a pilot double-blind crossover placebo-controlled study (n = 11) compared the analgesic efficacy of ADE with two other NSAID (indomethacin and diclofenac) drug/ether mixtures. Aspirin (but not indomethacin and diclofenac) was significantly superior to placebo as regards pain relief (P less than 0.05).

Trigeminal neuralgia and glossopharyngeal neuralgia.

Trigeminal neuralgia and glossopharyngeal neuralgia are extremely painful conditions that typically afflict an older population. Distinct clinical characteristics guide the diagnosis of these unique syndromes. Treatment involves medication first and then surgical procedures if a patient is refractory to medicinal therapy. Antiepileptic medications are the most effective agents for these disorders.

Epidemiology and clinical features of idiopathic trigeminal neuralgia and glossopharyngeal neuralgia: similarities and differences, Rochester, Minnesota, 1945-1984.

A comparison of epidemiological and clinical features of trigeminal neuralgia (TN) and glossopharyngeal neuralgia (GN) in Rochester, Minn., reveals several differences. The overall age- and sex-adjusted annual incidence rates were significantly higher for TN than for GN (4.7 vs. 0.8 per 100,000 population). The TN:GN ratio was increased for both men and women and was 5.9:1 for both sexes combined. This ratio is greater than reported in previous non-population-based studies. GN is a milder disease than TN, as indicated by the number of episodes, treatment, and characterization of pain. The right side is affected more often with TN than with GN. Bilaterality was noted less often in TN than in GN cases.

Microvascular decompression for treatment of trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia: three surgical approach variations: technical note.

OBJECTIVE: We have used three different approaches, namely, the infratentorial lateral supracerebellar approach, the lateral suboccipital infrafloccular approach, and the transcondylar fossa approach, for microvascular decompression for treatment of trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia, respectively. Each approach is a variation of the lateral suboccipital approach to the cerebellopontine angle (CPA); however, each has a different site of bony opening, a different surgical direction, and a different route along the cerebellar surface. METHODS: The infratentorial lateral supracerebellar approach is used to access the trigeminal nerve in the superior portion of the CPA through the lateral aspect of the cerebellar tentorial surface. The lateral suboccipital infrafloccular approach is directed through the inferior part of the cerebellar petrosal surface to reach the root exit zone of the facial nerve below the flocculus. The transcondylar fossa approach is used to access the glossopharyngeal nerve in the inferior portion of the CPA through the cerebellar suboccipital surface, after extradural removal of the jugular tubercle as necessary. RESULTS: In all three approaches, the cerebellar petrosal surface is never retracted transversely, that is, the cerebellar retraction is never directed parallel to the longitudinal axis of the VIIIth cranial nerve, dramatically reducing the risk of postoperative hearing loss. CONCLUSION: The greatest advantage of the differential selection of the surgical approach is increased ability to reach the destination in the CPA accurately, with minimal risk of postoperative cranial nerve palsy.

Trigeminal neuralgia and glossopharyngeal neuralgia: two orofacial pain syndromes encountered by dentists.

BACKGROUND: Dentists frequently evaluate patients for oropharyngeal pain that may or may not eventually be related to oral pathology. Two rare neurological disorders that present with severe orofacial pain are trigeminal neuralgia, or TN, and glossopharyngeal neuralgia, or GPN. Both are secondary to cranial nerve compression by arteries and veins at the point at which the nerves exit the pons and brainstem. RESULTS: The authors present the results for two series of patients treated for TN and GPN. Significant success can be seen after intracranial microvascular decompression for both disorders, with low complication rates. Short- and long-term outcomes depend on proper patient selection. CLINICAL IMPLICATIONS: It is important for practitioners to recognize these syndromes and properly refer patients to a neurosurgeon experienced in treating such disorders. This can help the dentist and patient avoid oral procedures that will not alleviate the painful symptoms.

[Facial neuralgia (neuralgia n. V). Diagnosis and treatment].

We present evaluation and methods of treatment for "tic douloureux" (trigeminal neuralgia). Angio-Magnetic Resonance seems to be essential in establishment of neuro-vascular compression pathology. Present diagnostic increased number of surgical intervention from suboccipital craniectomy approach in micro-vascular decompression. In patients with contraindications for general surgery other techniques are being used to decrease pain sensation: RF thermocoagulation with the help of stereotactic procedure, percutaneous microcompression of the trigeminal ganglion, radiosurgery, electrical stimulation of the Gasserian ganglion. Current methods of imaging and new therapeutical achievements allow to dramatically reduce pain and discomfort in first days of trigeminal neuralgia.
