Sudden sensorineural hearing loss (SSNHL) is an important otological emergency. Up to 90% of the cases are idiopathic. Cerebral venous thrombosis (CVT) is an extremely rare identifiable cause as it only represents 0.5% of all strokes.
In this paper, an unusual case of bilateral SSNHL secondary to bilateral CVT with rapid and complete recovery is reported. The patient presented with sudden bilateral hearing loss associated with some neurological symptoms. Initial computed tomography (CT) venography revealed a CVT of bilateral transverse sinuses. The patient was started on an anticoagulant and imaging was repeated after five days, revealing the absence of the thrombosis. Serial pure tone audiometry (PTA) showed complete recovery of bilateral hearing within 10 days.
Early detection and intervention may fasten hearing recovery and improve the quality of life. The immediate restoration of venous blood flow and intracranial pressure may lead to the complete recovery of bilateral hearing loss.
突发性感音神经性听力损失（SSNHL）是一种重要的耳科急症。高达90%的病例为特发性。脑静脉血栓形成（CVT）是一种极其罕见的可识别病因，仅占所有中风的0.5%。
本文报告了一例不寻常的双侧SSNHL继发于双侧CVT且快速完全恢复的病例。患者出现突发双侧听力损失并伴有一些神经症状。最初的计算机断层扫描（CT）静脉造影显示双侧横窦CVT。患者开始接受抗凝治疗，五天后重复成像，显示血栓消失。系列纯音听力测定（PTA）显示双侧听力在10天内完全恢复。
早期检测和干预可能加快听力恢复并改善生活质量。静脉血流和颅内压的立即恢复可能导致双侧听力损失完全恢复。
