78例开放式乳突根治鼓室成形术应用人工听骨后听力分析

摘要

Obejctive To analyze hearing outcomes of open mastoidectomy with tympanoplasty using ossicular pros⁃theses in patients with chronic otitis media. Methods Data from 78 patients who underwent open mastoidectomy with tympa⁃noplasty using ossicular prostheses were reviewed retrospectively. The average pure tone threshold before and after surgery was compared to assess the effect of ossicular prostheses. Results The hearing level in 52 of the 78 cases significantly im⁃proved, especially in those using partial ossicular prostheses. Conclusion Using ossicular prostheses in tympanoplasty fol⁃lowing open mastoidectomy can improve the hearing level in patients with chronic otitis media in whom surgical treatment is indicated.%　　目的分析开放式乳突根治+鼓室成形术应用人工听骨后的听力变化,并探讨人工听骨对中耳炎患者听力重建的作用.方法回顾性分析78例开放式乳突根治+鼓室成形术并行I期人工听骨听力重建患者的术前后听力变化情况(Pure-tone Average Threshold ,PTA).结果78例开放式乳突根治鼓室成形I期人工听骨听力重建患者术后听力有52例提高,其中部分听骨赝复物PROP植入后PTA提高者占72.4%,全听骨赝复物TORP植入后PTA提高者为65%.结论开放式乳突根治I期鼓室成形人工听骨植入使大多数中耳炎患者听力得到保存或补偿.
