The study reports a case that was responding well to sounds and suddenly stopped hearing following fever. She contracted bacterial meningitis at the age of 5 months and had sought an audiological opinion at the age of 7 years. On evaluation, the objective test results showed normal peripheral hearing, but behaviorally she did not respond to any sounds presented during pure-tone audiometry (PTA). Thus, she was evaluated for higher auditory function using late latency response (LLR) and the responses were absent bilaterally. This confirmed cortical deafness post meningitis. Meningitis can thus also cause cortical deafness in addition to peripheral hearing loss.
该研究报告了一例对声音反应良好但在发热后突然失聪的病例。她在5个月大时患了细菌性脑膜炎，并在7岁时寻求了听力方面的专业意见。经评估，客观测试结果显示外周听力正常，但在纯音听力测试（PTA）过程中，她对所呈现的任何声音都没有行为反应。因此，使用晚期潜伏期反应（LLR）对其更高层次的听觉功能进行了评估，结果显示双侧反应缺失。这证实了脑膜炎后皮质性聋。因此，脑膜炎除了可导致外周听力损失外，还可引起皮质性聋。
