Established Technique

Microvascular decompression is a well-established technique used to relieve abnormal vascular compression of cranial nerves and associated pain. Here the authors describe three cases in which a sling technique was used in the treatment of cranial nerve pain syndromes: trigeminal neuralgia with predominant V2 distribution, hemifacial spasm, and geniculate neuralgia and right-sided ear pain. In each case, the artery was mobilized from the nerve and tethered with a sling. All three patients had reduction of symptoms within 6 weeks.The video can be found here: https://youtu.be/iM7gukvPz6E

Object Microvascular decompression has become an accepted surgical technique for the treatment of trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia, and other cranial nerve rhizopathies. The senior author (P.J.J.) began performing this procedure in 1969 and has performed more than 4400 operations. The purpose of this article is to review some of the nuances of the technical aspects of this procedure. Methods A review of 4415 operations shows that numerous modifications to the technique of microvascular decompression have occurred during the last 29 years. Of the 2420 operations performed for trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia before 1990, cerebellar injury occurred in 21 cases (0.87%), hearing loss in 48 (1.98%), and cerebrospinal fluid (CSF) leakage in 59 cases (2.44%). Of the 1995 operations performed since 1990, cerebellar injuries declined to nine cases (0.45%), hearing loss to 16 (0.8%), and CSF leakage to 37 (1.85%) (p < 0.01, test for equality of distributions). The authors describe slight variations made to maximize surgical exposure and minimize potential complications in each of the six principal steps of this operation. These modifications have led to decreasing complication rates in recent years. Conclusions Using the techniques described in this report, microvascular decompression is an extremely safe and effective treatment for many cranial nerve rhizopathies.

Object.The authors undertook a study to identify magnetic resonance (MR) imaging techniques that can be used reliably during gamma knife surgery (GKS) to identify the trigeminal nerve, surrounding vasculature, and areas of compression.Methods.Preoperative visualization of the trigeminal nerve and surrounding vasculature as well as targeting the area of vascular compression may increase the effectiveness of GKS for trigeminal neuralgia. During the past years our gamma knife centers have researched different MR imaging sequences with regard to their ability to visualize cranial nerves and vascular structures. Constructive interference in steady-state (CISS) fusion imaging with three-dimensional gradient echo sequences (3D-Flash) was found to be of greatest value in the authors' 25 most recent patients.In 24 (96%) out of the 25 patients, the fifth cranial nerve, surrounding vessels, and areas of compression could be reliably identified using CISS/3D-Flash. The MR images were acceptable despite patients' history of microvascular decompression, radiofrequency (RF) ablation, or concomitant disease. In one of 25 patients with a history of multiple RF lesions, the visualization was inadequate due to severe trigeminal nerve atrophy.Conclusions.The CISS/3D-Flash fusion imaging has become the preferred imaging method at the authors' institutions during GKS for trigeminal neuralgia. It affords the best visualization of the trigeminal nerve, surrounding vasculature, and the precise location of vascular compression.

Between April 1989 and September 2007, 181 patients with disease of lower cranial nerves (DLCN) underwent posterior fossa exploration. As a cause of DLCN, vascular compression (VC) was present in 89 patients with trigeminal neuralgia (TN), in 6 with hemifacial spasm (HFS), in 1 with glossopharyngeal neuralgia, in 1 with Meniere?s disease, and in 5 with multiple DLCN. Depending on intraoperative findings, different surgical options were used: microvascular decompression (MVD), MVD with partial sensory rhizotomy (PSR) or total sensory rhizotomy (TSR). Statistic analysis was made using the Fisher?s exact 2-side test. In patients with TN, excellent outcome was archived in 83 patients and good in 6. Postoperative outcome was better (p = 0.007) in cases with severe VC, but without significant correlation between used surgical option and outcome (p = 0.402). Frequency rate of relapses did not depend on severity of VC (p = 0.502) and used surgical option (p = 0.175). In 6 patients with HFS, excellent outcome was archived in 5 with arterial compression and poor in 1 with venous contact. In patients with Meniere?s disease and glossopharyngeal neuralgia, MVD result with excellent outcome. In 5 patients with multiple DLCN, excellent outcome was archived in 3 and good in 2. MVD is method of choice in surgical treatment of DLCN caused by VC. Overall outcome is better with severity of VC.

Abstract Three patients with excruciating glossopharyngeal neuralgia underwent microsurgical operations in the posterior cranial fossa. In each patient, neurovascular compression was found involving the posteroinferior cerebellar artery and involving the 9th and 10th cranial nerves. In two of the patients, the compression was caused by arachnoiditis and in the other by an arterial loop. In each patient, neuralgia was successfully eliminated by microvascular decompression and by section of the upper rootlets of the vagus nerve. In one patient, partial section of the 9th cranial nerve was also performed. Because of the frequent involvement of the vagus nerve in the pathogenesis of this condition, open surgery should be preferable to percutaneous thermorhizotomy, which is unable to act selectively on the 10th cranial nerve.

Abstract OBJECTIVE To discuss the results of endoscope-assisted surgery in microvascular decompression (MVD) of Cranial Nerves (CNs) V, VII, and VIII. METHODS Neuroendoscopy was used as an adjunct to the surgical microscope in the MVD of the trigeminal (17 patients), facial (10 patients), and vestibulocochlear (1 patient) nerves in a series of 28 consecutive patients. After a standard microsurgical approach to CNs V, VII, and VIII, the endoscope was used to inspect all aspects of neural anatomy, to assess vascular compression, and to check the results of the decompression. Endoscope use was graded in four categories: Grade I, used but no definite role; Grade II, visualization assisted; Grade III, procedure assisted; and Grade IV, primary role. The usefulness of the endoscope was evaluated in each case. RESULTS The endoscope was useful in visualizing the anatomy in all cases. It was especially useful in establishing trigeminal vein compression of CN V in Meckel's cave; observing multiple sources of vascular compression; ensuring adequate decompression after cauterization of vein, insertion of the Teflon felt, or a pexy procedure; and permitting observation of the compression of CN VII at the root exit zone by small arteries and veins. In six patients with trigeminal neuralgia, the trigeminal vein was cauterized and divided by using endoscopic vision only because the venous compression was not completely visualized with the microscope. During a follow-up period of 6 to 52 months (mean, 29 mo; median, 40 mo), all patients were asymptomatic and receiving no medication. CONCLUSION The endoscope is a useful adjunct to MVD in the treatment of trigeminal neuralgia, hemifacial spasm, and disabling positional vertigo or tinnitus.

Background: There is a clear association between obesity and Idiopathic Intracranial Hypertension (IIH), a syndrome characterized by increased Intracranial Pressure (ICP). The clinical manifestations of IHH include headache and visual/oculomotor disorders due to the involvement of abducens nerve. Thus far, it has not been widely studied whether affectations by ICP elevation could involve other cranial nerves such as the trigeminal nerve.Objective: The aim of this study is to analyze the prevalence of elevated ICP in patients with BMI ≥ 25 that suffer vascular compression of the trigeminal nerve. Methods: A case series including 19 patients evaluated during a period of 8 months with BMI ≥ 25 and a clinical diagnosis of classic trigeminal neuralgia (TN) who underwent Microvascular Decompression (MVD) surgery is reported. Patients with TN presenting another cause of intracranial hypertension were excluded. The ICP was determined just before MVD surgery by introducing an enteral tube through a 2 mm incision in the dura and measuring the level reached by the CSF. Results: In our series, 42.1% of patients suffered overweight (n = 8), 47.3% grade I obesity (n = 9) and 10.5% grade II obesity (n = 2). The ICP was elevated in 47.4% of patients. Conclusion: IHH is an obesity-related disorder. Patients with BMI ≥ 25 and TN show a high prevalence of ICP. It is important to consider that an obese patient may present high ICP during and after MVD surger
