title: [Clinical comparison of idiopathic sudden deafness in children and the elderly].
abstract: OBJECTIVE
  This retrospective study compared clinical manifestations of idiopathic sudden hearing loss between children and the elderly.
  
  
  METHODS
  44 pediatric patients and 76 elderly patients diagnosed with idiopathic sudden deafness in our clinic from December 2009 to September 2014 were enrolled. Different clinical parameters were compared.
  
  
  RESULTS
  The incidence of initially profound hearing loss was highest and mild hearing loss was lowest in both groups (P < 0.05). There were no differences in the proportion with initially mild, moderate, severe, and profound hearing loss between both groups (P > 0.05). The number of patients was the most in initially profound type of audiogram pattern and the fewest in ascending type in both groups (P < 0.05). Hearing recovery rates in children (27/44, 61.4%) was higher than that in elderly patients (32/76, 42.1%) (P < 0.05). There were no differences in hearing recovery rates of the patients with initially level of hearing loss in both groups (P > 0.05). The highest recovery rate in children was in those with descending type and the lowest was in those with profound type (P < 0.05). There were no differences in hearing recovery rates in elderly patients with initially different types of audiogram pattern (P > 0.05). Hearing recovery rates of descending type in children were higher than that in elderly patients. Presence of tinnitus in pediatric patients was not relavent to the outcome (P > 0.05). Presence of tinnitus in elderly patients was associated with favorable outcomes. (P < 0.05). Presence of dizziness in pediatric patients was not relavent to the outcome (P > 0.05). Presence of dizziness in elderly patients was associated with poor outcomes (P < 0.05). Presence of initially different degrees of opposite side hearing loss in elderly patients was not relavent to the outcome (P > 0.05). Presence of chronic diseases in elderly patients was not associated with the outcome (P > 0.05).
  
  
  CONCLUSIONS
  The clinical manifestion of idiopathic sudden deafness is respective in Children and in elderly patients.
