目的:探讨振动声桥(VSB)圆窗植入技术对先天性前庭窗闭锁患者的疗效。方法:回顾性分析9例双侧先天性前庭窗闭锁患者的临床资料和术前后听力及言语功能检查结果。其中3例曾行/试行前庭开窗术,但术后效果不佳。所有患者术中均接受了VSB圆窗植入手术。结果:配戴VSB后,9例患者在语言频率区的听阈改善21~33dBHL;言语识别率改善更为明显,其中双音节词测试平均改善62%(术前为14%,VSB植入术后为76%),句子测试平均改善60%(术前为32%,VSB植入术后为92%)。平均随访51个月,2例出现术后听力下降,接受再手术后仍有1例远期听力未改善,其余患者均获得稳定改善的术后效果。结论:VSB圆窗植入技术应用于先天性前庭窗闭锁患者,可以获得较好的术后听力效果。
Objective: To evaluate the efficacy of the round-robin (VSB) window implantation in patients with congenital atresia. Methods: The clinical data of 9 patients with bilateral congenital atresia with atresia were analyzed retrospectively. Results of hearing and speech function before and after operation were analyzed. Three of them had / vestibular fenestration, but the results were not satisfactory. All patients underwent surgery for VSD round window implantation. Results: After wearing VSB, the hearing threshold of the 9 patients improved by 21 ~ 33 dBHL in speech frequency region. The improvement of speech recognition rate was more obvious. The average score of disyllabic word test was 62% (preoperative 14%), VSB implantation 76%), with an average of 60% improvement in sentence tests (32% preoperatively and 92% post VSB implantation). After a mean follow-up of 51 months, two patients experienced postoperative hearing loss. One patient remained without long-term hearing after reoperation. The remaining patients received stable and stable postoperative effects. Conclusion: VSB round window implantation technique can be used in patients with congenital atresia of the window to obtain good postoperative hearing effect.
