title: [Study of blood dynamics of ophthalmic artery in patients with sudden sensorineural hearing loss using color Doppler flow imaging].
abstract: OBJECTIVE
  To investigate the relationship between the pathogenesis of sudden sensorineural hearing loss (SSHL) and the disorder of blood circulation in inner ear.
  
  
  METHODS
  Blood dynamics of the ophthalmic artery were studied quantitatively using color doppler imaging in 34 patients with SSHL.
  
  
  RESULTS
  Compared with 34 self-controls and 15 normal controls, 28 patients (82.4%) with SSHL had significantly lower blood flow velocities and higher resistance indices (P < 0.05), and there was no significant difference between the self-control group and the normal control group (P > 0.05).
  
  
  CONCLUSIONS
  The study suggested that the blood situations--the decreased blood flow velocities and perfusion and increased resistance of ophthalmic artery in patients with SSHL maybe play a role in the pathogenesis of SSHL.
