摘  要:目的 探讨宽频声导抗声能吸收率测试在Ⅰ型鼓室成形术后患者中耳功能状态评估中的应用价值。方法 收集住院单纯鼓膜穿孔患者纳入手术组,均行Ⅰ型鼓室成形术,术后随访6个月,每次复诊复查纯音测听和宽频声导抗测试,同时收集32名(64耳)听力正常人的宽频声导抗测试数据作为对照,设为正常组。结果 手术组入组患者共41例,3例术后1个月复诊发现鼓膜小穿孔,2例术后2个月复诊时发现鼓膜小穿孔。最终完成6个月随访的患者有32例(共32耳),平均年龄(35.48±15.25)岁,平均病史(11.14±9.34)年。纯音测听于术后3个月趋于稳定,声能吸收率于术后5个月趋于稳定。结论 鼓膜修补术患者术后5个月声能吸收率趋于稳定,对于术后患者建议可随访至术后5个月。Objective To explore the application value of energy absorbance of wideband acoustic immittance in evaluating the middle ear function of patients after typeⅠtympanoplasty.Methods The hospitalized patients with simple tympanic membrane perforation were selected as the operation group and all underwent typeⅠtympanoplasty.After 6 months of follow-up,pure tone audiometry and wideband acoustic immittance energy absorbance test were performed at each follow-up visit,and wideband acoustic immittance energy absorbance test data of 32 normal subjects(64 ears)were collected as control group.Results A total of 41 patients were enrolled in surgery group,and three patients were found small perforation of tympanic membrane after one month,and two with perforation after two months.Thirty-two patients(32 ears)were completed 6-month follow-up,with an average age of(35.48±15.25)years old,and an average history of(11.14±9.34)years.Pure tone audiometry and energy absorbance rate tended to be stable at 3 months,and 5 months,respectively,after operation.Conclusion The energy absorbance tends to be stable at 5 months after operation,and it is recommended that the patients should be followed up for 5 months after tympanoplasty.
