“…This approach is commonly used for removal of CPA tumors, such as acoustic schwannomas, and microdecompression of AICA branches in hemifacial spasm. 9,13,20,30,34,35,38,64 As performed in our case, skeletonization and lateral retraction of the transverse-sigmoid junction allows for minimal cerebellar retraction. If additional exposure is desired, a partial petrosectomy may be performed with the opening of the presigmoid dura.…”

Aneurysms of the anterior inferior cerebellar artery (AICA) are relatively rare among intracranial aneurysms. They can occur in 1 of 3 regions of the AICA: 1) craniocaudal (high or low riding), 2) mediolateral-premeatal (proximal), and 3) meatal-postmeatal (distal). The management strategies for treatment differ according to the location and configuration of the aneurysm. The existing body of neurosurgical literature contains articles published on aneurysms arising from the AICA near the basilar artery (BA), intracanalicular/meatal aneurysms, and distal AICA. Several therapeutic options exist, encompassing microsurgical and endovascular techniques. The authors describe a case of treatment involving a large BA-AICA aneurysm approached via exposure of the presigmoid dura using a retromastoid suboccipital craniectomy and partial petrosectomy. Treatment of these lesions requires detailed knowledge of the anatomy, and an anatomical overview of the AICA with its arterial loops and significant branches is presented, including a discussion of the internal auditory (labyrinthine) artery, recurrent perforating arteries, subarcuate artery, and cerebellosubarcuate artery. The authors discuss the various surgical approaches (retromastoid, far lateral, subtemporal, and transclival) with appropriate illustrations, citing the advantages and disadvantages in accessing these AICA lesions in relation to these approaches. The complications of these different surgical techniques and possible clinical effects of parent artery occlusion during AICA surgery are highlighted.

“…65,66 Compression by an atherosclerotic, aberrant, or ectatic intracranial artery near the REZ, first described in 1947 by Campbell and Keedy, 14 has been recognized as one of the most common mechanisms of this condition. Other sources of compression include arteriovenous malformation (AVM), 71 aneurysm, 71,72 different types of brain tumors, 13,17,72,93 meningioma, 16,72,83 and bony abnormalities of the skull 25,93 localized in the ipsilateral cerebellopontine angle (CPA) or on the contralateral side, distorting the normal anatomy of the ipsilateral facial nerve. 60,75 Peripheral facial nerve injury or prior Bell's palsy can also result in HFS.…”

“…over the last 30 years an increasing volume of evidence has been presented to support a vascular compression aetiology of hemifacial spasm [1][2][3][4][5][6][7][8][9][10][11] . In these cases the facial nerve compression appeared to be the result of normal, tortuous, ectatic or redundant blood vessels 1,2 , aneurysm 3 , arteriovenous malformation [4][5][6][7][8][9][10] , and dural arteriovenous fistula (dAVF) 11 . We describe a case of petrosal dAVF causing classi-cal hemifacial spasm in a 56-year-old man followed by a complete relief of symptoms after transarterial onyx embolization.…”

This paper reports that decompression of the facial nerve by transarterial Onyx embolization may relieve hemifacial spasm (HFS) caused by dilated veins due to a right petrosal dural arteriovenous fistula (DAVF). A 56-year-old man suffered severe chronic right HFS associated with a dilated right petrosal vein lying in the vicinity of the facial nerve. The right petrosal DAVF was reached through the middle meningeal artery using a transfemoral arterial approach and was occluded with Onyx 18 (M.T.I.- ev3, Irvine, CA, USA). There was complete remission of HFS without recurrence after two months of follow-up. This case supports vascular compression in the pathogenesis of HFS and suggests that facial nerve injury caused by a DAVF could be treated with transarterial Onyx embolization.
