Abstract：
We report resolution of right-sided pulsatile tinnitus in a 44-year-old male who underwent stapedectomy for fenestral otosclerosis. Initial workup revealed a mixed hearing loss and absent stapedial reflexes consistent with ossicular fixation. CT angiography demonstrated near complete stenosis of the left-sided transverse and sigmoid sinuses and dominant contralateral venous outflow. We hypothesized that the dominant right cerebral venous outflow tract created turbulent flow that was conducted to cochlea. Successful stapedectomy was performed, and the pulsatile tinnitus resolved. This case report demonstrates evidence that the sound of turbulent blood flow can be conducted through bone and an instance where the perception of vascular tinnitus was eliminated with stapedectomy.
摘要：
我们报告了一名44岁的男性因窗耳硬化而接受stapedex切除术的右侧搏动性耳鸣的解决方法。最初的检查显示混合的听力损失和与听骨固定一致的骨反射缺失。CT血管造影显示左侧横窦和乙状窦几乎完全狭窄，并主要对侧静脉流出道。我们假设主要的右脑静脉流出道产生了湍流，并传导到耳蜗。成功进行了stapede切除术，搏动性耳鸣解决了.此病例报告表明，有证据表明，湍流的血液流动声音可以通过骨骼传导，并且可以通过stapedex切除术消除血管耳鸣的感觉。
