【摘要】：目的探讨自体听骨用于听骨链重建术的临床疗效。方法回顾性分析58例(60耳)应用自体听骨行听骨链重建术患者的临床资料,术后随访时间3-18个月,平均11.6个月,分析言语频率的纯音听阈及气骨导差。结果术后无一例自体听骨脱出,3例移位,无鼓膜再穿孔、内陷,所有患者术后均干耳。平均纯音听力气导由术前54.7±6.4 d B提高到术后39.0±9.1d B,骨导由术前28.3±4.6 d B提高到22.2±4.2d B,PTA-ABG由术前26.4±7.9 d B缩小到16.8±8.2 d B,手术成功率(术后PTA-ABG≤20d B)为71.7%(43/60)。结论自体听骨取材方便、费用低、组织相容性好,塑形后用于听骨链重建可取得良好的听力效果,是听骨链重建术的理想材料。
[Abstract]:Objective to investigate the clinical curative effect for autologous ossicular ossicular reconstruction. Methods Retrospective analysis of 58 cases (60 ears) with autologous ossicular ossicular chain reconstruction of clinical data of patients, the postoperative follow-up period was 3-18 months, average 11.6 months, by difference analysis of speech frequency pure tone and air bone. Results after the operation no cases of autologous ossicular prolapse, 3 cases of transposition, no tympanic membrane perforation, retraction, all patients had dry ears. The average air conduction hearing from preoperative 54.7 B to + 6.4 D 39 + 9.1d B after surgery, bone conduction from preoperative 28.3 B to + 4.6 D 22.2 + 4.2d B, PTA-ABG from preoperative 26.4 + 7.9 D B + 8.2 D B reduced to 16.8, the success rate of surgery (postoperative PTA-ABG = 20d B) 71.7% (43/60). Conclusion autologous ossicular is convenient, low cost, good biocompatibility, shaping for ossicular chain reconstruction can achieve good listening effect is. The ideal material for reconstruction of ossicular chain.

【正文快照】： 自上世纪50年代Zollner和Wullstein首次提出鼓室成形术的概念和分型,开启了现代耳显微外科听力重建的里程碑。经过几十年的发展,慢性中耳炎手术在彻底清除中耳病变后的听骨链重建技术及重建材料的研究取得了显著的进步,重建中耳声音传导结构成为现代耳显微外科手术的重要内容
