A 35-year-old man had a 5-year history of fluctuating hearing loss in his only hearing ear. History and diagnostic tests indicated a perilymph fistula, a diagnosis subsequently confirmed by exploration. Primary and secondary repairs temporarily ameliorated symptoms. A spinal fluid to middle ear fluid pathway was identified by radioactive tracer. A patent cochlear aqueduct indicated on computed tomography scan was found and repaired through a posterior cranial fossa approach. Hearing was preserved, remaining relatively stable during the 2-year follow-up period.
一名35岁男性，其唯一听力耳存在波动性听力损失5年。病史及诊断检查提示存在外淋巴瘘，该诊断随后经探查得以证实。一期和二期修复暂时缓解了症状。通过放射性示踪剂确定了脑脊液至中耳液的通路。计算机断层扫描显示存在开放的蜗水管，并通过后颅窝入路进行了修复。听力得以保留，在2年随访期内保持相对稳定。
