Tumors, and one third of patients with large tumors still have near-normal (>Ĩ0%) speech discrimination. Speech reception (SRT) is normal in many patients with small tumors.Įxcellent speech discrimination is found in about 50% of patients with small This estimate is probably wrongĪs it would imply a much higher prevalence of acoustic neuromas than are commonly Hearing loss have acoustics (Daniels et al, 2000) - amounting to 5/100. It has also been estimated that 5 percent of persons with asymmetrical sensorineural Have acoustics (although other studies suggest 1/100 - see below). However, recall that only about 1 in 1000 patients with hearing asymmetry Out of 20 patients with large tumors have symmetry within 15 dB at 4000 Hz. Is an asymmetrical high-frequency sensorineural hearing loss (see figure above left). Hearing testing is the most useful diagnostic test for acoustic neuroma. See comment in textĬonventional audiometry (hearing testing) This example shows that symmetrical hearing testing does not always exclude the diagnosis of an acoustic neuroma. The blue boxes are the left (acoustic) ear.Īudiogram of patient with large acoustic neuroma on left side, but (nearly) symmetrical hearing.

It was managed by facial nerve decompression by translabyrinthine approach in an attempt to prevent further deterioration of facial palsy.īangladesh J Otorhinolaryngol 2012 18(2): 179-182 The diameter of the IAC was less than 2 mm on high resolution temporal bone computed tomography (HRCT) scan. Here is presentation of a case of unilateral (left) IAC stenosis with profound hearing loss and progressive House Brackmann Grade III-IV facial weakness. High resolution temporal bone CT-scan and magnetic resonance imaging (MRI) are the important tools for diagnosis. Patient may present with symptoms of progressive facial nerve palsy, hearing loss, tinnitus and giddiness. Internal auditory canal (IAC) stenosis is a rare cause of sensorineural hearing loss.
