Hearing complaints have been described in patients after lumbar puncture, although other symptoms like headache, nausea, and dizziness can easily obscure hearing disorders. Reduced cerebrospinal fluid pressure after lumbar puncture may explain the origin of this vestibulocochlear dysfunction. Two cases of hearing loss and tinnitus that appeared hours after otherwise uncomplicated diagnostic spinal puncture are reported. The pure tone audiogram showed a 40-50 dB bilateral sensorial hearing loss in the lower frequencies. Hearing recovered and tinnitus disappeared entirely within 7-10 days. Since permanent hearing loss has been reported after diagnostic or therapeutic lumbar puncture, we should be aware of the possibility of this adverse effect.
腰椎穿刺后患者曾有听力方面的主诉，尽管诸如头痛、恶心和头晕等其他症状很容易掩盖听力障碍。腰椎穿刺后脑脊液压力降低可能解释了这种前庭蜗神经功能障碍的起因。本文报告了两例在诊断性脊髓穿刺未出现其他并发症数小时后出现听力损失和耳鸣的病例。纯音听力图显示低频出现双侧40 - 50分贝的感音性听力损失。听力在7 - 10天内恢复，耳鸣完全消失。由于诊断性或治疗性腰椎穿刺后曾有永久性听力损失的报告，我们应该意识到这种不良反应的可能性。
