OBJECTIVE
To perform an assessment of the viability of cochlear implantation in a patient with superficial siderosis of the brain.
STUDY DESIGN
Case review.
SETTING
Tertiary referral center.
PATIENTS
Patient with superficial siderosis of the brain.
INTERVENTION
Cochlear implantation.
MAIN OUTCOME MEASURES
Electrically evoked auditory brainstem responses and fitting strategy for cochlear implant based on patient's subjective responses.
RESULTS
After some time, C levels and T levels showed a pattern comparable with the evoked auditory brainstem responses.
CONCLUSIONS
Bilateral profound hearing loss after superficial siderosis of the brain is no absolute contraindication for implantation. Furthermore, evoked auditory brainstem measurements can potentially guide the fitting process of the implant in difficult cases.
目的
评估脑表面铁沉积症患者进行人工耳蜗植入的可行性。
研究设计
病例回顾。
研究地点
三级转诊中心。
患者
脑表面铁沉积症患者。
干预措施
人工耳蜗植入。
主要观察指标
电诱发听性脑干反应以及基于患者主观反应的人工耳蜗适配策略。
结果
一段时间后，C水平和T水平呈现出与诱发听性脑干反应相似的模式。
结论
脑表面铁沉积症导致的双侧极重度听力损失并非人工耳蜗植入的绝对禁忌证。此外，在疑难病例中，诱发听性脑干测量可能有助于指导人工耳蜗的适配过程。
