Abstract:
BACKGROUND AND OBJECTIVES: The prognosis and prognostic factors for acute acoustic trauma are difficult to predict. The aim of this study was to assess the prognostic factors of acute acoustic trauma. SUBJECTS AND METHOD: The cases selected for this report are 27 patients with acute acoustic trauma and 139 patients with sudden deafness are selected for control group. The following factors were examined for prognostic factors: age, vestibular symptom, degree of initial hearing loss, number of days before the start of treatment. RESULTS: Most strongly related factor for prognosis is number of days before the start of treatment, but other factors are not significant relation for prognosis. The overall hearing recovery rate of acute acoustic trauma was 29.6% and that of sudden deafness is 56.1%. CONCLUSION: Early treatment of acute acoustic trauma increases hearing recovery rate, and acute acoustic trauma has worse prognosis than sudden deafness.
