Abstract

Objective

An observation of a difficult-to-diagnose complication of the cochlear implant: recurring cutaneous extrusion of a cochlear implant is reported.

Patients and methods

The history of an adult patient with total deafness is reported. She received an implant in her right ear in 1988, which was then explanted because of absence of hearing results. She received a second implant in her left ear in 2002, which was then explanted in 2007 because of cutaneous extrusion. In 2008, a second implant of a different brand was placed in her left ear, with the central part placed away from the first site, but extrusion recurred. A new attempt to encapsulate the central part with a hydroxyapatite box also ended in extrusion and was explanted in 2008.

Results

Various diagnoses to explain these cutaneous problems were suggested during this clinical progression: infection, allergy, and a reaction to a foreign body. No hypothesis could be clearly ruled out.

Conclusion

Cutaneous complications after cochlear implant are exceptional. As soon as cutaneous disorders appear, a rigorous diagnostic process must be followed so that the patient can be recommended a long-lasting solution to restore quality hearing.

反复挤压人工耳蜗的皮肤
目的观察人工耳蜗术后复发性皮肤挤压的并发症。患者和方法报告1例成人全聋患者的病史。1988年,她的右耳接受了人工耳蜗植入手术,后来由于听力不佳而被摘除。2002年,她在左耳接受了第二次植入手术,2007年,由于皮肤挤压,她的左耳被摘除。2008年,在她的左耳植入了第二个不同品牌的植入物,将中心部分放置在远离第一个位置的位置,但挤压复发。用羟基磷灰石盒子包裹中心部位的新尝试也以挤压告终,并于2008年进行了移植。结果在此临床进展过程中,提出了多种诊断来解释这些皮肤问题:感染、过敏和对异物的反应。没有任何假设可以被明确地排除。结论人工耳蜗术后皮肤并发症少见。一旦出现皮肤疾病,必须遵循严格的诊断过程,以便向患者推荐持久的解决方案,以恢复高质量的听力。
