RÉSUMÉ
BACKGROUND AND OBJECTIVES: This study examined whether the prognosis of sudden deafness was dependent on the time of onset and evaluated the factors affecting prognosis during each period. SUBJECTS AND METHODS: Patients who developed sudden hearing loss from January 2005 to December 2015 were evaluated retrospectively. Meteorological data were obtained from the official website of the Korea Meteorological Administration. Factors prognostic of hearing recovery rate were analyzed. RESULTS: The hearing recovery rate of the 318 patients who developed sudden deafness did not differ significantly by month. Mean temperature and daily temperature range at onset of sudden deafness were not associated with recovery rate. CONCLUSIONS: The recovery rate in patients with sudden deafness did not differ markedly by season.

BACKGROUND AND OBJECTIVES: This study was designed to assess the characteristics of patients according to the degree and audiogram shape of hearing loss and the association of these characteristics with hearing aids (HA) choice, return rate, and cause of return. SUBJECTS AND METHODS: This study included 460 individuals who received HAs from 2011 to 2015. The relationships between type of HA and age, primary and accompanying symptoms, HA choice and return and cause of return were evaluated according to the degree and pattern of hearing loss. RESULTS: HA type did not differ significantly according to the degree and pattern of hearing loss. Intensity of hearing loss was greater in male than in female (p<0.05). Open and completely-in-canal types of HA decreased with age (p<0.05). As degree of hearing loss intensified, behind-the-ear and in-the-ear types increased and Open type decreased (p<0.05). The HA return rate was 9.7%, but was not associated with degree or pattern of hearing loss. The main causes of HA return were costs, psychological fears and adaptive failure. CONCLUSIONS: Choice of HA is affected by age, sex, and degree and pattern of hearing loss. HA for hearing rehabilitation in patients with hearing loss can be personalized according to each patient's characteristics and tendencies.
