Background and ObjectivesZZSudden sensorineural hearing loss (SSNHL) in children can occur just as can in adults; in fact, it may last throughout the entire life of a child, affecting the individual much more than when it does to an adult. As there are only a few studies that have focused on SSNHL in childhood, we investigated the clinical characteristics and hearing outcomes of pediatric SSNHL. Subjects and MethodZZA retrospective review of patients from November 2005 to May 2014 was carried out. Thirty nine patients under the age 15, who were hospitalized due to SSNHL were enrolled. Of these patients, 226 patients over the age of 15 were collected as a comparison group. Age, sex, underlying disease, site of hearing loss and duration from the onset to treatment were analyzed. We evaluated the overall recovery rate as well as the recovery rate according to accompanying diseases. ResultsZZRecovery rates were comparable between the pediatric and the adult group. Overall recovery rate was 60% in the pediatric group. Unlike for the adult group, dizziness and tinnitus were not a prognostic factor in the pediatric group. Pediatric patients showed similar overall recovery, whether the treatment initiation was under 7 days or more. Recurrence was seen in 3 patients, of which 2 showed complete recovery. ConclusionZZThe recovery rate for SSNHL was similar for the pediatric and the adult groups. A higher recurrence rate may alert clinicians to be aware of hearing changes after the recovery in pediatric patients.

Methods:The first 400 patients submitted to the Swedish national database for SSNHL were analyzed. Information was collected at the first visit about the patient's past medical history, potential precipitating events traumata, family medical history, hearing loss, current disease, diagnostic protocol and treatment using questionnaires as well as two audiograms for each patient, one at the first visit to the ENT-clinic and one three months later.Results: 65% of these 400 patients underwent hematological tests and 40% had an MRI/CT.22/160 MRI investigated had pathological findings: five acoustic neuromas, one subdural hematoma, one pons infarction, five vascular abnormalities and ten patients had accidental findings not connected to the hearing tracts. 300 of these 400 patients were evaluated as idiopathic sudden sensorineural hearing loss (ISSNHL); 24% of them had one or more pathological tests. No significant correlation was found between either the MRI findings or the laboratory findings with regard to either treatment or hearing recovery in patients with ISSNHL. Conclusion:Results from a database for SSNHL demonstrate no correlation between laboratory findings, treatment and outcome in 400 patients. The patients with pathological tests were not treated differently from those with normal tests or no tests taken. The value of laboratory findings and MRI might increase if the results are categorized to more specific diagnoses.

The majority of the evidence reviewed was poorly reported and there is therefore an inherent risk of bias. Given the recent improvement in resolution and reduction in cost of MR imaging, ABR can no longer be considered appropriate as the primary test used to screen for acoustic neuroma. T2W or T2*W sequences enable accurate evaluation of the VIIIth and VIIth cranial nerves within the cerebellopontine angle and internal auditory canal as well as evaluation of the cochlea and labyrinth, and inclusion of GdT1W sequences is unlikely to contribute information that would alter patient management in the screening population. The quality of the imaging chain and experience of the reporting radiologist are key factors determining the efficacy of a non-contrast screening strategy. Based on a cost-effectiveness model developed to reflect UK practice it was concluded that a diagnostic algorithm that deploys non-contrast MR imaging as an initial imaging screen in the investigation of acoustic neuroma is less costly than and likely to be as effective as available contrast MR imaging.
