The bone-anchored hearing aid (BAHA) Attract is a transcutaneous bone conduction hearing aid that uses magnetic coupling to enable sound conduction. We report the first case of skin necrosis associated with the BAHA Attract and perform a literature review of soft tissue complications related to the device.
A single patient who was found to develop skin necrosis 2 weeks after being fitted for the BAHA Attract speech processor.
After the patient developed skin necrosis from the device, she was advised to immediately discontinue use of the Attract to allow complete wound healing, upon which the Attract was successfully converted to a percutaneous BAHA.
We monitored for the development of skin complications from the BAHA Attract. The patient's immediate postoperative course was unremarkable and she was fitted with a speech processor of M5 magnet strength at 1 month postoperatively. After 1 week of use, she reported discomfort and was advised to downgrade to an M4 magnet; however, she continued to use the M5 and the following week was found to have developed skin necrosis around the device.
Despite the infrequency of skin necrosis related to the BAHA Attract, it must be considered in counseling and managing candidates for the device.
骨锚式助听器（BAHA）Attract是一种经皮骨传导助听器，利用磁耦合实现声音传导。我们报告了首例与BAHA Attract相关的皮肤坏死病例，并对与该设备相关的软组织并发症进行了文献综述。
一名患者在佩戴BAHA Attract言语处理器2周后出现皮肤坏死。
患者因该设备出现皮肤坏死，建议立即停止使用Attract，以使伤口完全愈合，之后Attract成功转换为经皮BAHA。
我们监测了BAHA Attract皮肤并发症的发生情况。患者术后即刻病程平稳，术后1个月佩戴了M5磁强的言语处理器。使用1周后，她报告不适，建议降级至M4磁体；然而，她继续使用M5，随后一周发现设备周围出现皮肤坏死。
尽管与BAHA Attract相关的皮肤坏死并不常见，但在为该设备的候选者提供咨询和管理时必须考虑到这一点。
