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。
Objective To report outcomes of ossiculoplasty with autologous ossicles. Methods Fol- low-up data of 58 patients （60 ears） who underwent ossiculoplasty using autologous auditory ossicles were analyzed retrospectively. Patients were followed up for 3-18 months with an average of 11.6 months. Preand post-operative pure tone average （PTA） air-conduction thresholds, bone-conduction thresholds and air-bone gap （ABG） at 0.5, 1 and 2 kHz were analyzed. Results There were no postoperative autologous ossicle grafts extrusion. There were graft displacement in three cases without tympanic membrane perforation or invagination. All patients achieved dry ear postoperatively. Air conduction thresholds improved from a preoperative average of 54.7±6.4 dB HL to a postoperative average of 39.0±9.1 dB HL, while bone conduction thresholds improved from a preoperative average of 28.3±4.6 dB HL to a postoperative average of 22.2±4.2 dB HL, with air-bone gaps decreased from a preoperative average of 26.4±7.9 dB to a postoperative average of 16.8±8.2 dB. Postoperative PTA-ABG was reduced to 20 dB or less in 71.7% （43/60） of the cases. Conclusion Consid- ering the convenient availability, low expense, high levels of histocompatibility, low rate of complications and excellent hearing results, autogenous ossicles, with minimal reshaping, are ideal materials that can be successfully applied in ossiculoplasty.
