【摘要】：目的回顾性分析钛人工听骨(宾格牌)在植入术后假体脱出的原因,以期进一步提高人工听骨植入手术的成功率。方法自2007年2月到2013年7月间,共完成一期钛金属人工听骨植入听骨链重建术206耳。其中,POP164耳,TOP42耳。结果 206例中,共计脱出12个,占5.8%。分别是术后3周感染脱出3耳;随访中钛听骨渐外露至完全排出9耳。致钛听骨渐外露的因素有:1)钛听骨高度过高。2)钛听骨歪斜。3)软骨片过小、薄、移位。4)含气腔渐变小。结论植入材料选择、手术技巧、术后中耳含气腔的变化均是影响假体脱出的因素。其中,就宾格牌钛听骨而言,其支撑面的平面形态设计和锐利的切缘可能是导致术后远期假体脱出的一个潜在因素。
[Abstract]:Objective to analyze retrospectively the causes of prosthesis prolapse after implantation of titanium artificial ossicle (Binger) in order to further improve the success rate of artificial ossicular implantation. Methods from February 2007 to July 2013, A total of 206 ears were reconstructed with titanium metal artificial ossicular ossicular implantation. Among them, there were 164 ears with POP and 42 ears with Topp. Results 12 of 206 cases (5.8%) were out of the total, 3 ears were infected 3 weeks after operation. During the follow-up, the titanium ossicular bone was gradually exposed to the full exudation of 9 ears. The factors causing the titanium ossicular ossicular exposure were: 1) the titanium ossicular ossicular height was too high. 2) the titanium ossicular ossicular ossicular deformity. 3) the cartilage slice was too small, thin, shift. 4) the air-containing cavity gradually became smaller. Conclusion the implant material selection, surgical techniques, The change of the air cavity in the middle ear after operation is the factor affecting the prolapse of the prosthesis, among which, the plane shape design of the supporting surface and the sharp cutting edge of the Binger titanium auricle may be one of the potential factors leading to the prolapse of the prosthesis in the long term after operation.
