摘要
目的评估植入式骨导助听器在双侧先天性小耳畸形患者听觉重建中的应用效果。方法前瞻性对2018年5月~2019年2月在我院行全耳郭再造手术的15例双侧先天性外中耳畸形患者同期植入索菲康Alpha骨导助听器。耳再造采用Nagata二期法,于全耳郭再造二期手术时行骨导系统植入。术前进行声场下纯音测听(PTA)及言语识别阈(SRT)测试;术后2周进行骨导助听器外机佩戴,开机当天、佩戴后3个月及6个月重复测试其在声场下PTA及SRT,并记录患者的不良反应。结果双侧小耳畸形患者在未进行助听前的声场下PTA为(57.6±4.6)dB HL,开机当天和佩戴3、6个月后的PTA分别为(21.8±3.5)、(20.7±4.5)、(19.5±2.9)dB HL。平均声场PTA改善了37 dB HL,差异具有统计学意义(P<0.05);助听后患者各方向SRT较助听前亦有明显改善,差异具有统计学意义(P<0.05)。各组患者无明显手术及佩戴相关不良反应。结论植入索菲康骨导助听器可有效改善双侧先天性小耳畸形患者的听阈及言语识别能力。
Objective To evaluate the hearing benefits of implanted bone conduction hearing aid in congenital microtia.Methods Fifteen patients suffered from bilateral congenital microtia from Eye&ENT Hospital of Fudan University were implanted with Sophono bone conduction hearing aid during their ear reconstruction operations.Audiological tests were performed under unaided(before implantation)and aided conditions(0 day,3 months and 6 months after implantation),including free field tests of the hearing thresholds and speech recognition thresholds(SRT)in quiet.Adverse events were also documented by a self-reported questionnaire.Results The pure tone average(PTA,in free field)under unaided condition were(57.6±4.6)dB HL.It improved to(21.8±3.5),(20.7±4.5),(19.5±2.9)dB HL,respectively,0 day,3 months and 6 months after the implantation.Statistically significant improvements of about 37 dB HL in free field thresholds were found between the unaided and aided conditions.In aided conditions,SRT in quiet were significantly improved compared to unaided condition.No adverse events related to the surgery and devices was reported.Conclusions The Sophono implanted bone conduction hearing aid is an alternative choice to improve bilateral congenital microtia patients with satisfactory audiological outcomes in hearing thresholds and speech recognition.
