Study of blood dynamics of ophthalmic artery in patients with sudden sensorineural hearing loss using color doppler flow imaging / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

Objective: To investigate the relationship between the pathogenesis of sudden sensorineural hearing loss (SSHL) and the disorder of blood circulation in inner ear. Method:Blood dynamics of the ophthalmic artery were studied quantitatively using color doppler imaging in 34 patients with SSHL. Result: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 selfcontrol group and the normal control group (P＞0.05). Conclusion: 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.
