Abstract

Five patients with idiopathic sudden sensorineural hearing loss (ISSHL) were examined by a combination of high-resolution computed tomography and special magnetic resonance imaging techniques. By three-dimensional constructive interference in steady state magnetic resonance imaging excellent visualization of the membranous labyrinth was obtained. No fibrous or osseous obliteration of the intralabyrinthine fluid spaces was observed in all investigated temporal bones. The results provide further evidence for a viral pathogenesis of ISSHL.

摘要

对5例特发性突发性感音神经性听力损失（ISSHL）患者采用高分辨率计算机断层扫描和特殊磁共振成像技术相结合的方法进行检查。通过稳态磁共振成像中的三维相干扰相梯度回波序列，获得了膜迷路的良好可视化图像。在所有研究的颞骨中均未观察到迷路内液腔的纤维性或骨性闭塞。这些结果为ISSHL的病毒发病机制提供了进一步的证据。
