自体听骨链与人工听骨链治疗慢性中耳炎听力损害的效果比较

Effect comparison of autologous ossicular chain and artificial ossicular chain in the treatment of chronic otitis media with hearing impairment

目的评估自体听骨链与人工听骨链治疗慢性中耳炎听力损害的临床效果。方法回顾性分析我院及中山大学附属第二医院2014年2月~2016年10月行听骨链重建的慢性中耳炎患者78例的临床资料,按听骨链重建材料分为自体听骨链组(n=47)及人工听骨链组(n=31)。比较两组患者术前及术后6个月的听力改善效果及并发症发生情况。结果两组患者术前纯音测听骨导、气导听力阈值及气骨导听力阈值差值(ABG)差异无统计学意义(P>0.05),人工听骨链组术后6个月的纯音测听骨导、气导听力阈值及ABG均低于自体听骨链组(P<0.05)。两组术后并发症发生率差异无统计学意义(P>0.05)。结论人工听骨链重建治疗慢性中耳炎听力损害能明显降低听力阈值,改善听力,具有较好的临床效果。

Objective To evaluate the clinical effect of autologous ossicular chain and artificial ossicular chain in the treatment of chronic otitis media with hearing impairment.Methods Clinical data of 78 patients with chronic otitis media who underwent ossicular reconstruction from February 2014 to October 2016 in our hospital and the Second Hospital Affiliated to Zhongshan Medical Sciences University were retrospectively analyzed.According to the different ossicular chain reconstruction material,they were divided into the autologous ossicular chain group （n=47） and artificial ossicular chain group （n=31）.The hearing improvement before surgery and after 6 months surgery and occurrence of complications in patients between the two groups were compared.Results The bone-conduction threshold and air-conduction threshold in pure tone test and the airLbone gap （ABG） before surgery were not displayed significant differences between the two groups （P〉0.05）.Mter 6 months surgery,the bone-conduction threshold and air-conduction threshold in pure tone test and ABG of the artificial ossicular chain group was lower than that of those of the autologous ossicular chain group （P〈0.05）.There was no great difference of the incidence of postoperative complications between the two groups （P〉0.05）.Conclusion Artificial ossicular chain reconstruction in the treatment of chronic otitis media with hearing impairment can remarkably decrease the hearing threshold,improve bearing,and obtain a favorable clinical effect.
