Çocuklarda ani sensörinöral işitme kaybı: etiyoloji, prognostik faktörler ve tedavi sonuçları

Abstract

Aim: Sudden sensorineural hearing loss (SSNHL) may have a negative impact on the language and psychological development of children, especially if it is not diagnosed early and treated promptly. This study were aimed to determine and compare the etiological factors, treatment outcomes and prognostic factors in the pediatric patients who were followed up with the diagnosis of SSNHL. Materials and Methods: The files of 28 children were analyzed retrospectively. In pure tone audiometry, the average of pure tone thresholds of 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz were accepted as pure tone averages (PTAV). Patients' recovery status was determined according to Siegel criteria. Audiometric curve types were evaluated as ascending, descending, and flat. Results: The ages of patients with SSNHL was mean ± SD 14.89 ± 3.24 (min-max: 7 and 18). The pre-treatment PTAV was mean ± SD 55.27 ± 12.39 dB HL (min-max: 38.5 and 85.25 dB HL) and the PTAV after treatment was mean ± SD 23.13 ± 18.22 dB HL (min-max: 5 and 72.5 dB HL). Audiometric curve types were detected as descending curve (n: 11, 39.2%), ascending curve (n: 5, 17.9%), flat curve (n: 12, 44.9%). Eighteen (64.3%) patients had complete recovery, 8 (28.6%) patients had partial recovery, and 2 (7.1%) patients had no recovery after the treatment. Conclusion: The response to treatment was found to be high. Descending audiometric curve type was found as a positive prognostic factor. Although the presence of tinnitus was a better prognostic factor than the presence of vertigo.
