Clinical perspectives of anterior inferior cerebellar artery: a review

<p class="abstract">The anterior inferior cerebellar artery arises at the cerebellopontine angle (CPA), usually from lower one third of basilar artery. However, vascular anatomy (AICA) is highly variable. In respect to neurovascular relationship in internal auditory canal (IAC), AICA intimately related with vestibulocochlear and facial nerve. Microvascular compression nerve by an important etiology for tinnitus, hearing loss vertigo. The loop or aneurysm will compress canal. should be separated Magnetic resonance angiography (MRA) helpful reveal pathology confirm causes disabling otological symptoms. After confirmation AICA, surgery planned. intrameatal conflict produce specific pathological features their surgical treatment also invariably challenging. objective this review article discuss details anatomy, etiopathology, clinical presentations, diagnosis, neurophysiology current anomalies IAC which often pose challenge clinicians.</p>
