摘要
细菌性脑膜炎是儿童获得性感音神经性听力损失的最常见原因,一旦发生就会迅速引发耳蜗骨化,即骨化性迷路炎。医疗团队应该意识到这些潜在的威胁,并监测这些患者的听力功能。如果怀疑听力损失,在完全耳蜗骨化前进行听力学和放射学评估是迫切需要的,因为它会发展为深度听力损失,并降低人工耳蜗植入的成功率。虽然CT扫描能发现耳蜗骨化,但有时为时已晚。最近,MRI可以发现早期的耳蜗内迷路炎骨化阶段,允许在适当的时候进行人工耳蜗植入手术。*通信对象:Miura MS,巴西阿雷格里港联邦大学医学外科Ciências Saúde和圣克里安帕拉医院儿科耳鼻咽喉科Antônio, PósGraduação em Ciências巴西阿雷格里港联邦大学南里奥格兰德州大学医学院,E-mail: mmiura.voy@terra.com.br收稿日期:2018年6月29日接收日期:2018年7月9日;细菌性脑膜炎(BM)是儿童获得性感音神经性听力损失(SNHL)的最常见原因[1,2-9,10-12]。由于脑膜炎可诱发骨化性迷路炎(LO), 5-7%的患者会出现听力损失[7]。这个过程可能很快,医疗团队应该监测这些患者的听力功能,并指导父母/照顾者注意任何与言语、语言、对环境声音的反应或行为变化有关的障碍。怀疑听力损失,迫切需要进行听力学和放射学评估。
Post meningitis profound hearing loss: MRI as a predictor tool for urgent cochlear implant
Bacterial meningitis is the most common cause of acquired sensorineural hearing loss in children, once it could quickly trigger ossification of cochlea, known as labyrinthitis ossificans. Medical team should be aware of such potential threaten and monitor hearing function of these patients. On suspicion of hearing loss, it is urgent to proceed audiological and radiological evaluation before complete cochlear ossification, since it evolves to profound hearing loss and reduces successful cochlear implant insertion. Although CT scan detect cochlear ossification, it sometimes too late. More recently, MRI could detect early intracochlear labyrinthitis ossificans stages, allowing cochlear implant surgery in the right moment. *Correspondence to: Miura MS, Department of Medical Surgery of Universidade Federal de Ciências da Saúde de Porto Alegre and Division of Pediatric Otorhinolaryngology at Hospital da Criança Santo Antônio, Programa de PósGraduação em Ciências Médicas-Faculdade de Medicina da Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil, E-mail: mmiura.voy@terra.com.br Received: June 29, 2018 Accepted: July 09, 2018; Published: July 12, 2018 Introduction Bacterial meningitis (BM) is the most common cause of acquired sensorineural hearing loss (SNHL) in children [1,2-9,10-12]. 5-7% of patients will develop hearing loss, since meningitis induces to labyrinthitis ossificans (LO) [7].
