Percutaneous bone conduction implants are widely used in patients with conductive and mixed hearing loss with no benefit from conventional air conduction hearing aids. These devices have several complications including skin reaction, wound infection, growth of skin over the abutment, and implant extrusion. We describe a case of a transcutaneous bone conduction implantation (Bonebridge, Med-el) in a patient with conductive hearing loss due to chronic otitis media. Surgical planification was performed with the software 3D slicer 4.1. According to this program, the implant transductor was positioned in the retrosigmoid area. Aided thresholds demonstrate a significant benefit, with an improvement from 68dB to 25dB. Speech discrimination scores improved 35dB. The patient is very happy and uses her device daily. The Bonebridge implant is a promising transcutaneous bone conduction implant for patients with conductive hearing loss. Retrosigmoid implantation may be useful in cases with mastoid pathology or previous surgery.
经皮骨传导植入物广泛应用于传导性和混合性听力损失患者，这些患者使用传统气导助听器无效。这些装置有多种并发症，包括皮肤反应、伤口感染、基台周围皮肤生长以及植入物挤出。我们描述了一例因慢性中耳炎导致传导性听力损失患者的经皮骨传导植入（骨桥，美迪乐公司）病例。使用软件3D Slicer 4.1进行手术规划。根据该程序，将植入式换能器置于乙状窦后区域。助听阈值显示出显著改善，从68分贝提高到25分贝。言语辨别得分提高了35分贝。患者非常满意，每天都使用该装置。骨桥植入物对于传导性听力损失患者是一种很有前景的经皮骨传导植入物。乙状窦后植入在有乳突病变或既往手术的病例中可能有用。
