“…Tinnitus due to the pressure of the enlarging acoustic neurinomas in the IAC on the CN in the IAC has been reported [23]. Having a temporary improvement in patients with acoustic tumor, sudden hearing loss and tinnitus complaints after steroid treatment was interpreted as the outcome of decompression of the 8th nerve by steroid [24]. Cerebellopontine angle or internal acoustic canal lipomas cause many symptoms depending on the structures adjacent to them.…”

ObjectivesThe aim of the present study was to evaluate the internal auditory canal (IAC) and the nerves inside it to define possible structural differences in cases with subjective tinnitus of unknown origin.MethodsCases applying to the ear, nose and throat department with the complaint of tinnitus with unknown origin and having normal physical examination and test results were included in the study (n=78). Patients admitted to the radiology clinic for routine cranial magnetic resonance imaging (MRI) and whose MRI findings revealed no pathologies were enrolled as the control group (n=79). Data for the control group were obtained from the radiology department and informed consent was obtained from all the patients. Diameters of the IAC and the nerves inside it were measured through enhanced images obtained by routine temporal bone MRIs in all cases. Statistical evaluations were performed using Student t-test and statistical significance was defined as P<0.05.ResultsMeasurements of IAC diameters revealed statistically significant differences between the controls and the tinnitus group (P<0.05). Regarding the diameters of the cochlear nerve, facial nerve, inferior vestibular nerve, superior vestibular nerve, and total vestibular nerve, no statistically significant difference was found between the controls and the tinnitus group.ConclusionNarrowed IAC has to be assessed as an etiological factor in cases with subjective tinnitus of unknown origin.

“…Aslan et al 4 found 57% of patients with SHL and acoustic neuroma reported some or complete recovery in their hearing; 36% suffered recurrent bouts of SHL. Mineta et al 18 reported 2 patients with idiopathic SHL who had partial recovery after steroid treatment. Hearing loss recurred, and VS was diagnosed.…”

“…Any or all of these may play a role, but given the acute nature and sudden onset of the hearing loss, a vascular event as the cause has received the most support. Interestingly, among patients with SHL and VS, there is a further subgroup of patients whose hearing actually recovers before tumor removal, either after some form of treatment for the SHL or after no treatment at all 3,18,19 …”

“…I n his 1917 monograph on the diagnosis and management of acoustic tumors, Cushing 1 described two patients with sudden hearing loss (SHL). Since that time there have been numerous reports of SHL in acoustic neuroma (AN) patients 2‐17 . According to Moffat et al, 17 10.2% of AN patients have SHL as their primary symptom, making SHL the second most common initial symptom in AN patients 17 .…”

“…Nedzelski and Dufour 4 concluded that SHL/AN patients will generally have abnormal caloric electronystagmography (ENG) and poor hearing recovery. There have been numerous recent reports, however, of SHL recovery in patients with an AN 10,11,14 . Likewise, ENG findings in SHL/AN have varied between studies.…”

Patients with acoustic neuroma may have sudden sensorineural hearing loss. Most patients with sudden hearing loss seek medical attention promptly, but the diagnosis of an acoustic neuroma may be delayed for months or years because sudden hearing loss is an unusual initial symptom of an acoustic neuroma. In a retrospective review of 836 cases of sudden hearing loss, we found 13 patients with acoustic neuromas. The prevalence of acoustic neuromas for those screened with auditory brain stem response or magnetic resonance imaging was 2.5%. In addition to these 13 patients, 79 acoustic neuroma patients treated in our clinic had well-documented sudden hearing loss as the initial symptom. Hearing loss in these 92 patients ranged from mild to profound. Associated symptoms of pain, facial paresthesia, or unilateral tinnitus preceding the sudden hearing loss were suggestive of an acoustic neuroma, as was a midfrequency (U-shaped) hearing loss. A history of other diseases or events that might explain the sudden hearing loss, a normal electronystagmogram, or recovery of hearing does not eliminate the possibility of a tumor. Because there are no clinical findings that clearly distinguish those patients with acoustic neuromas from other patients with sudden hearing loss, we recommend either an evaluation with auditory brain stem response or gadolinium-enhanced magnetic resonance imaging for any patient with sudden hearing loss.
