PURPOSE
Patients affected by severe atresia auris (AA) can be a challenge during hearing restoration surgery due to the abnormal position of vascular and nervous structures in the bone. A 3D reconstruction model of malformed temporal bones can be helpful for planning surgery and optimizing intra-, peri-, and post-operative results.
METHOD
A 5-year-old girl with severe AA on the right side was implanted with a Bonebridge transcutaneous bone conduction implant (tBCI). 3D printing was used to reproduce the malformed temporal bone, find a good position for the tBCI and plan out the surgical details in advance. Hearing tests were performed before and after surgery and information about intra-, peri-, and post-operative outcomes were collected.
RESULTS
The patient did not show any negative outcomes and, thanks to the Bonebridge, completely recovered hearing on the right side.
CONCLUSIONS
3D printing is a useful tool for planning surgery in AA patients and for preventing possible risks related to the unknown malformed anatomy.
目的
由于血管和神经结构在骨中的异常位置，严重的先天性外耳闭锁（AA）患者在听力修复手术中可能是一个挑战。畸形颞骨的 3D 重建模型有助于手术规划，并优化手术的围术期结果。
方法
一名 5 岁女孩右侧患有严重 AA，植入 Bonebridge 经皮骨导植入物（tBCI）。使用 3D 打印技术复制畸形颞骨，为 tBCI 找到一个良好的位置，并提前规划手术细节。在手术前后进行听力测试，并收集围手术期内、围手术期和术后的信息。
结果
患者没有出现任何不良后果，并且得益于 Bonebridge，右侧听力完全恢复。
结论
3D 打印是 AA 患者手术规划和预防与未知畸形解剖相关的潜在风险的有用工具。
