耳内镜下Ⅰ型鼓室成形与术后耳鸣改善的临床研究

Clinical study of type Ⅰ tympanoplasty under otoscope and postoperative tinnitus improvement

摘要:

目的 探讨鼓膜穿孔伴耳鸣患者耳内镜下听力重建术后耳鸣改善情况。方法 对35例就诊于广西中医药大学附属瑞康医院和广西壮族自治区人民医院的伴有耳鸣症状的慢性化脓性中耳炎（静止期）或外伤性鼓膜穿孔患者进行纯音测听，并运用耳鸣致残量表（THI）对患者的耳鸣状况进行术前和术后评价。结果 听力重建术后，85.71%患者耳鸣消失或减轻，且平均听阈值、THI评分较术前下降，差异有统计学意义（P < 0.05）。听力改善越大，手术前后THI差值也越大，听力改善程度与手术前后THI差值呈正相关（r = 0.778，P = 0.000）。结论 耳内镜下Ⅰ型鼓室成形后，大部分患者听力改善，可帮助患者减轻耳鸣症状，树立信心。

Abstract:

Objective To investigate the improvement of tinnitus in patients with tympanic membrane perforation and tinnitus after hearing reconstruction under otoscope.Methods 35 patients with chronic suppurative otitis media (stationary phase) or traumatic tympanic membrane perforation with tinnitus symptoms were received audiologic assessments, and the tinnitus handicap inventory (THI) was used to evaluate the tinnitus status before and after the operation.Results After audile reconstruction surgery, 85.71% of the patients' tinnitus disappeared or alleviated, and the auditory threshold average and THI score were lower than those before the operation, the difference was statistically significant (P < 0.05). The greater the hearing improvement, the greater the THI difference before and after the operation, and the hearing improvement was positively correlated with the THI difference before and after the operation (r = 0.778, P = 0.000).Conclusion After type Ⅰ tympanoplasty under otoscope, the hearing of most patients improved, which can help alleviate the symptoms of tinnitus and build up patients' confidence.
