The results were compared to the literature and IMVSs treated by our group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Anacusis and progressive hearing loss were more frequent in the present population than the cases reviewed (<jats:italic>P<\/jats:italic> = .0064 and <jats:italic>P<\/jats:italic> = .0001, respectively). Hearing loss affected more than 90% of the patients, with anacusis in 32.1% of the cases. Facial palsy affected 17.9% of the patients. In comparison to IMVSs, preoperative anacusis was more associated to meningiomas (<jats:italic>P<\/jats:italic> = .0037), and the facial nerve was more compromised in ICMs than IMVSs, both preoperatively (<jats:italic>P<\/jats:italic> = .0011) and at follow\u2010up (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.0001).<\/jats:p><jats:p>According to a re\u2010evaluation of preoperative MRIs and comparison with IMVSs, linear tumor borders, and linear morphology along the internal auditory canal wall, but not the presence of a dural tail, were significantly more present in ICMs (<jats:italic>P<\/jats:italic> = .0035, <jats:italic>P<\/jats:italic> = .0004, <jats:italic>P<\/jats:italic> = .1963, respectively).
