OBJECTIVE
To highlight the potential adverse outcomes with cochlear implantation (CI) in patients with superficial siderosis.
PATIENTS
Two patients with superficial siderosis of the central nervous system with secondary sensorineural hearing loss.
INTERVENTION
Cochlear implantation.
MAIN OUTCOME MEASURE
Postimplantation speech discrimination scores.
RESULTS
In both cases, initial results after implantation were promising. However, in 1 case, their ability to use the CI rapidly declined after 1 week because of major difficulties adapting to electrical stimulation. For the other case, hearing rapidly declined over a 6-month period.
CONCLUSION
The 2 patients reported did not benefit from CI in superficial siderosis that is in contrast to several previously published cases. Adequate counseling of patients with superficial siderosis is important when considering cochlear implantation as results are variable.
目的
强调中枢神经系统表面铁沉积症患者接受人工耳蜗植入（CI）可能产生的不良后果。
患者
两名患有中枢神经系统表面铁沉积症并继发感音神经性听力损失的患者。
干预措施
人工耳蜗植入。
主要观察指标
植入后的言语辨别得分。
结果
在这两个病例中，植入后的初始结果都很有希望。然而，在1例中，由于适应电刺激存在重大困难，其使用人工耳蜗的能力在1周后迅速下降。对于另1例，听力在6个月内迅速下降。
结论
所报告的这2例中枢神经系统表面铁沉积症患者未从人工耳蜗植入中获益，这与之前发表的几个病例形成对比。考虑人工耳蜗植入时，对中枢神经系统表面铁沉积症患者进行充分的咨询很重要，因为结果存在差异。
