Loss of hearing is a sequelae of meningitis. This hearing loss has been known to fluctuate for as long as one year following the acute infection. This paper presents a case of an 11-year documented downward fluctuating hearing loss following Haemophilus influenzae meningitis. The case indicates that patients should be followed audiologically for years following meningitis. A review of the literature of hearing loss in meningitis is presented with special emphasis on cases in which the hearing loss fluctuated. The cases in the literature were usually not followed for more than one year. In this case of acquired hearing loss secondary to Haemophilus influenzae meningitis, the patient's hearing fluctuated over 11 years, in a downward progression. It is not clear what type of mechanism is involved in the ongoing damage to the cochlea that could account for this gradual fluctuation. It is suggested that as the possibility of long-term fluctuation exists, patients with meningitis should be monitored audiologically for many years.
听力丧失是脑膜炎的后遗症。已知这种听力丧失在急性感染后的长达一年时间里会出现波动。本文介绍了一例11年来记录在案的流感嗜血杆菌脑膜炎后听力呈下行波动的病例。该病例表明，脑膜炎患者在脑膜炎发病后的数年里都应接受听力检查随访。本文对脑膜炎所致听力丧失的文献进行了综述，特别强调了听力丧失出现波动的病例。文献中的病例通常随访时间不超过一年。在这例继发于流感嗜血杆菌脑膜炎的获得性听力丧失病例中，患者的听力在11年里呈下行波动。目前尚不清楚导致耳蜗持续受损从而造成这种渐进性波动的机制类型。鉴于存在长期波动的可能性，建议对脑膜炎患者进行多年的听力检查监测。
