Are aica vascular loops in inner auditory canal common in healthy population without any symptoms?
A doctor has provided 1 answer
Probably unknown: To find out, researchers would have to study the anatomy of a large group of normal people's heads. One paper published in 1991 found that 12% of heads they studied had such loops and concluded they found "no correlation between unexplained hearing loss, tinnitus, vertigo, or Meniere's disease and the presence of the anterior inferior cerebellar artery in the internal auditory canal."
