彩色多普勒血流仪对突聋患者的眼动脉血流观察

目的 :探讨突聋发病与微循环障碍的关系。方法 :采用 Acuson 12 8XP/ 10彩色多普勒血流仪检测34例突聋患者及 15例正常人的眼动脉血流参数。结果 :突聋患者 2 8例 (82 .4% )患侧眼动脉的血流速度低于健侧眼动脉和对照组 ,血管阻力高于对照组 ,两组间差异有显著性意义 (P <0 .0 5 )。结论 :提示突聋患者患侧眼动脉的低流速、低灌注、高阻力型血流状态改变 ,可能与突聋发病有关。

Study of blood dynamics of ophthalmic artery in patients with sudden sensorineural hearing loss using color doppler flow imaging

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 self-control 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.
