title: [Analysis of prognosis factors of idiopathic sudden hearing loss].
abstract: OBJECTIVE
  To study the prognosis factors of idiopathic sudden hearing loss.
  
  
  METHODS
  The clinical data of 165 patients with idiopathic sudden hearing loss were retrospectively studied and the computer software was used to investigate the relevant effects on prognosis.
  
  
  RESULTS
  The prognosis of patients who had been treated within 14 days under the age of 55 were better. The prognosis of the elderly and the patients with vertigo and high hearing loss were not satisfied. Sex, tinnitus, cardiac or cerebral vascular diseases, diabetic and the medicine or the duration of treatment have no statistical points on prognosis.
  
  
  CONCLUSIONS
  The prognosis of idiopathic sudden hearing loss related with the treatment time and coverage and extent of the damaged inner ear.
