报告了植入 Vibrant Med-El Soundbridge((R)) (VSB) 设备的受试者的早期临床结果。目前的 VSB 标准限制其适用于中耳功能正常的患者，现已扩展到包括听骨链缺陷的患者。七名患有严重混合性听力损失的患者植入了放置在圆窗上的换能器。所有患者都曾接受过手术：其中 6 人接受了多次听骨成形术，1 人将 VSB 压接在砧骨上，但结果不成功。圆窗植入绕过正常的传导路径并向耳蜗提供放大的输入。大多数受试者的术后辅助阈值达到了 30 dB HL，而无辅助阈值范围为 60-80 dB HL。 50%清晰度时的辅助语音接收阈值为50 dB HL，大多数受试者在对话水平上达到100%清晰度，而无辅助阈值平均为80 dB HL，只有一名受试者达到100%清晰度。这些结果表明，圆窗植入可能为接受不成功听骨成形术的严重混合性听力损失患者提供可行的治疗选择。
Early clinical findings are reported for subjects implanted with the Vibrant Med-El Soundbridge((R)) (VSB) device. The present criteria for the VSB, limiting its application to patients with normal middle ear function, have been extended to include patients with ossicular chain defects. Seven patients with severe mixed hearing loss were implanted with the transducer placed onto the round window. All had undergone previous surgery: six had multiple ossiculoplasties, and one had the VSB crimped on the incus with unsuccessful results. Round window implantation bypasses the normal conductive path and provides amplified input to the cochlea. Post-operative aided thresholds of 30 dB HL were achieved for most subjects, as compared with unaided thresholds ranging from 60-80 dB HL. Aided speech reception thresholds at 50% intelligibility were 50 dB HL, with most subjects reaching 100% intelligibility at conversational levels, while unaided thresholds averaged 80 dB HL, with only one subject reaching 100% intelligibility. These results suggest that round window implantation may offer a viable treatment option for individuals with severe mixed hearing losses who have undergone unsuccessful ossiculoplasties.
