目的 :探讨中耳炎手术 期听骨链重建的最佳材料和术式。方法 :回顾性分析 389例慢性化脓性中耳炎患者的听骨链重建手术所见及术后效果。结果 :大鼓室 型采用人工听骨者听力提高优于其它各种重建方法和重建材料 (P <0 .0 1)。重建砧镫关节者听力提高稍差于采用人工听骨的大鼓室 型 ,但明显优于其他重建方法和重建材料 (P <0 .0 1)。结论 :大鼓室 型采用人工听骨者听力提高优于其它各种重建方法和重建材料 ,利用自体听骨作赝复材料者均不如利用人工听骨效果好。
Objective: To investigate the best materials and procedures for ossicular chain reconstruction during otitis media surgery. Methods: A retrospective analysis of 389 cases of chronic suppurative otitis media in patients with skeletal reconstruction surgery and see the results. Results: The tympanic cavity with artificial ossicles was superior to other reconstruction methods and reconstruction materials (P <0.01). The improvement in the hearing of the anvils was slightly worse than that of the large tympanic system using artificial ossicles, but significantly better than other reconstruction methods and reconstructive materials (P <0.01). Conclusion: The tympanic cavity with artificial ossicles improves hearing better than other reconstruction methods and reconstructive materials. The use of autologous ossicles as prosthetic materials is not as good as using artificial ossicles.
