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

Diseases of ephaptic transmission are commonly caused by vascular compression of cranial nerves. The advent of microvascular decompression has allowed for surgical intervention for this patient population. This chapter highlights the technique of endoscopic-assisted microvascular decompression for trigeminal neuralgia and hemifacial spasm. Endoscopy and keyhole techniques have resulted in a minimally invasive and effective treatment of symptoms for patients with neuralgia.

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.

✓ To determine the causative factors of unsuccessful microvascular decompression for hemifacial spasm, the follow-up results in 53 patients were assessed retrospectively. The mean follow-up period was 36 months. There were 32 patients who had compression of the seventh cranial nerve ventrocaudally by an anterior inferior cerebellar artery (AICA) or a posterior inferior cerebellar artery. Of these 32 patients, 30 (94%) had excellent postoperative results. Of 14 patients with more severe compression by the vertebral artery, nine (64%) had excellent results, three (21%) had good results, and two (14%) had poor results; in this group, three patients with excellent results experienced transient spasm recurrence. There were seven patients in whom the meatal branch of the AICA coursed between the seventh and eighth cranial nerves and compressed the dorsal aspect of the seventh nerve; this was usually associated with another artery compressing the ventral aspect of the nerve (“sandwich-type” compression). Of these seven patients, five (71%) had poor results including operative failure in one and recurrence of spasm in four. The authors conclude that the clinical outcome was closely related to the patterns of vascular compression.

Abstract OBJECTIVE We report a case of hemifacial spasm in a patient who had associated hearing loss, numbness throughout the face, tinnitus, and vertigo, all of which occurred when turning his head to the left. To our knowledge, these symptoms have not occurred in this pattern and with a single trigger. CLINICAL PRESENTATION A 45-year-old man presented with a 3-year history of right-sided hemifacial spasm initially treated with botulinum toxin. One month before presentation, he had an episode of acute hearing loss in the right ear when turning his head to the left, followed by multiple episodes of transient hearing loss in his right ear, numbness in his right face in all distributions of the trigeminal nerve, tinnitus, and vertigo. He was found to have decreased sensation in nerves V1 to V3 and House-Brackmann grade 3/6 weakness in his right face, despite not having botulinum toxin injections in more than a year. Magnetic resonance imaging/angiography showed an ectatic vertebrobasilar system causing compression of the fifth, seventh, and eighth cranial nerves. INTERVENTION The patient underwent a retromastoid craniotomy and microvascular decompression. Postoperatively, he had complete resolution of his symptoms except for his facial weakness. The benefit has been long-lasting. CONCLUSION Multiple, simultaneous cranial neuropathies from vascular compression are rare, but this case is an example of safe and effective treatment with microvascular decompression with durable results.

AbstractA 53-year-old male patient had been suffering from severe aural symptoms (pulsatile right-sided tinnitus and paroxysmal dizziness attacks with nausea) and right hemifacial spasm. Treatment had involved stellate ganglion block with lignocaine and the injection of intravenous sodium bicarbonate solution for attacks of Meniere's syndrome and facial nerve block with lidocaine for hemi-facial spasm. Despite these treatments, the dizzy attacks became more frequent, developing into the clustering state. Air CT cisternography and vertebral angiography demonstrated an enlarged and curved vertebral artery. Vascular cross-compression of the Vllth and VHIth cranial nerves was therefore suspected. Microvascular decompression was performed. After operation, the pulsatile tinnitus, dizziness and hemifacial spasm disappeared. From the present case and a review of the literature, we conclude that vascular cross-compression of the VHIth cranial nerve should be an indication for microvascular decompression only when symptoms of vascular cross-compression of the Vllth cranial nerve are also seen.

Microvascular decompression (MVD) is a neurosurgical procedure used to treat various neuralgias of the cranial nerves. The clinical presentation, natural history, pathophysiology, and medical management of trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia, and nervus intermedius neuralgia is reviewed. A thorough discussion on the retrosigmoid approach for decompression of cranial nerves is presented, along with newer techniques and controversies on adjuvant therapies and neuromonitoring. The surgical outcomes of MVD are discussed, along with alternative techniques to open MVD.

OBJECTIVEIn microvascular decompression surgery for trigeminal neuralgia and hemifacial spasm, the bridging veins are dissected to provide the surgical corridors, and the veins of the brainstem may be mobilized in cases of venous compression. Strategy and technique in dissecting these veins may affect the surgical outcome. The authors investigated solutions for minimizing venous complications and reviewed the outcome for venous decompression.METHODSThe authors retrospectively reviewed their surgical series of microvascular decompression for trigeminal neuralgia and hemifacial spasm in patients treated between 2005 and 2017. Surgical strategies included preservation of the superior petrosal vein and its tributaries, thorough dissection of the arachnoid sleeve that enveloped these veins, cutting of the inferior petrosal vein over the lower cranial nerves, and mobilization or cutting of the veins of the brainstem that compressed the nerve roots. The authors summarized the patient characteristics, operative findings, and postoperative outcomes according to the vascular compression types as follows: artery alone, artery and vein, and vein alone. They analyzed the data using chi-square and 1-way ANOVA tests.RESULTSThe cohort was composed of 121 patients with trigeminal neuralgia and 205 patients with hemifacial spasm. The superior petrosal vein and its tributaries were preserved with no serious complications in all patients with trigeminal neuralgia. Venous compression alone and arterial and venous compressions were observed in 4% and 22%, respectively, of the patients with trigeminal neuralgia, and in 1% and 2%, respectively, of those with hemifacial spasm (p < 0.0001). In patients with trigeminal neuralgia, 35% of those with artery and venous compressions and 80% of those with venous compression alone had atypical neuralgia (p = 0.015). The surgical cure and recurrence rates of trigeminal neuralgias with venous compression were 60% and 20%, respectively, and with arterial and venous compressions the rates were 92% and 12%, respectively (p < 0.0001, p = 0.04). In patients with hemifacial spasm who had arterial and venous compressions, their recurrence rate was 60%, and that was significantly higher compared to other compression types (p = 0.0008).CONCLUSIONSDissection of the arachnoid sleeve that envelops the superior petrosal vein may help to reduce venous complications in surgery for trigeminal neuralgia. Venous compression may correlate with worse prognosis even with thorough decompression, in both trigeminal neuralgia and hemifacial spasm.

ABSTRACT OBJECTIVE To provide the characteristics and long-term surgical results of patients who present with cerebellopontine angle epidermoids and trigeminal neuralgia (TN) or hemifacial spasm. METHODS A total of 30 patients (23 women, 7 men) who presented with cerebellopontine angle epidermoids and TN (28 patients) or hemifacial spasm (2 patients) between 1982 and 1995 were reviewed, with emphasis being placed on the clinical manifestations, the mechanisms of symptom development, the long-term follow-up results, and the anatomic relationship between the tumor and the surrounding neurovascular structures. RESULTS The average age of the patients was 37.8 years at symptom onset and 49.3 years at the time of the operation. The tumor-nerve relationships were classified into four types: complete encasement of the nerve by the tumor, compression and distortion of the nerve by the tumor, compression of the nerve by an artery located on the opposite side of the unilateral tumor, and compression of the nerve by an artery on the same side of the tumor. Total resection was achieved in 17 patients (56.7%). Microvascular decompression of the respective cranial nerve was achieved in nine cases of direct arterial compression in addition to tumor removal. The symptom was relieved completely in all cases. In an average follow-up period of 11.5 years, three patients developed recurrent symptoms: two experienced tumor regrowth, and one had arachnoid adhesion. CONCLUSION Hyperactive dysfunction of the cranial nerves, especially TN, may be the initial and only symptom that patients with cerebellopontine angle epidermoids experience. The occurrence of TN at a younger age was characteristic of TN patients with epidermoids, in contrast to patients with TN due to a vascular cause. The symptom is elicited by compression of the nerve by the tumor per se, by an artery that is displaced to the nerve, or by both. Careful resection of the tumor, whose capsule occasionally is strongly adherent to the neurovascular structures, is necessary, and microvascular decompression to straighten the neuraxis should be performed in some cases to achieve a complete, permanent cure of symptoms with a low rate of recurrence.

✓ The concept of microvascular compression (MVC) is discussed critically. The root entry or exit zone is defined: it is much shorter than generally realized. The anatomy of the intracranial vessels is considered, as well as known facts concerning trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia relating to MVC. The results of microvascular decompression (MVD) are analyzed; one-third of patients do not obtain an optimum result. The evidence used to support the hypothesis of MVC, including neurophysiology, is discussed and it is believed to be insufficient and unconvincing. The basis of MVD could be trauma of the nerve during operative dissection and “decompression.” The concept of MVC might be more convincing if MVD can be shown to cure a condition such as spasmodic torticollis, which cannot be remedied by damage to or section of the same cranial nerve or nerves.
