We measured the length and width of the internal auditory canal (IAC) to investigate a possible association between a narrow porus, the presence of an anterior inferior cerebellar artery (AICA) loop, and the development of a microvascular compression syndrome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We performed a prospective blinded analysis of 167 magnetic resonance imaging scans of the cerebellopontine angle. The presence of an AICA loop was scored. We analyzed these 167 patients for unilateral sensorineural hearing loss, which was defined as an interaural difference of 20 dB at 1 frequency or 10 dB at 2 or more frequencies. Furthermore, the width and length of the IAC on magnetic resonance imaging were measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>An AICA loop was identified in 94% of the 167 patients. There were 196 type I loops, 106 type II loops, and 14 type III loops. Sixty-six patients had unexplained unilateral hearing loss. There was no association between type II and III vascular loops, the width of the IAC, and unilateral hearing loss (p &gt; .05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>In this study we found no association between the depth of extension of the AICA loop into the IAC and the presence of unilateral hearing loss.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/000348940711600404","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:40:52Z","timestamp":1412347252000},"page":"248-252","source":"Crossref","is-referenced-by-count":23,"title":["Is Microvascular Compression of the Vestibulocochlear Nerve a Cause of Unilateral Hearing Loss?"],"prefix":"10.1177","volume":"116","author":[{"given":"Femke","family":"van der Steenstraten","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
