摘要
目的 探讨振动声桥（Vibrant Soundbridge,VSB）植入的手术效果.方法 根据VSB植入的手术适应证,分别对1例感音神经性聋患者和1例传导性聋（先天性小耳畸形）患者进行VSB植入.感音神经性聋患者术前纯音测听（0.5、1、2、4 kHz）平均听阈（听力级）为56 dB,小耳畸形患者的平均气导听阈为61 dB.术后7周开机调试.结果 2例患者术后听力均获改善,声场助听听阈（0.5、1、2、4 kHz）：感音神经性聋患者为32 dB,获益24 dB;传导性聋（小耳畸形）患者为40 dB,获益21 dB.2例患者术后均无面神经麻痹、眩晕及耳鸣.结论 VSB植入对于感音神经性聋和传导性聋均有效.
Objective To investigate the effect of Vibrant Soundbridge （ VSB） implantation.Methods In accordance with the indications for VSB implantation,surgeries were done for two patients who suffered from either a sensorineural or conductive hearing loss （ microtia）.Their preoperative auditory thresholds（0.5,1,2 and 4 kHz） were 56 dB HL and 61 dB HL.The VSB was turned on and adjusted seven weeks after surgery.Results Postoperative auditory thresholds of the two patients were improved.Their pure tone thresholds were 32 dB HL and 40 dB HL,and the respective improvement was 24 dB HL and 21 dB HL.There was no facial paralysis,vertigo and tinnitus.Conclusion Patients with a sensorineural or conductive hearing loss may benefit from VSB implantation.
