目的 探讨慢性化脓性中耳乳突炎 (胆脂瘤或骨疡型 )手术方法及其治疗的远期疗效。方法 总结了 1990～ 1997年间经 3年以上随访的 113例乳突根治伴鼓室成形术病例 ,对比分析了开放式乳突根治鼓室成形术(Open -mastoidectomywithtympanoplasty ,OMT)与联合进路鼓室成形术 (combinedapproachtympanoplasly ,CAT)的优缺点及远期疗效。结果 OMT手术远期听力较术前听力气导提高 12dBHL ,CAT为 9.5dBHL ,提高幅度二者并无显著差别 ;从远期复发率看 ,OMT为 5 .8% ,CAT为 2 4 .4 % ,两者有显著差别。结论 就远期效果看本组病例OMT手术优于CAT手术。
Objective To investigate the surgical treatment of chronic suppurative otitis media (cholesteatoma or bone ulcer type) and its long-term curative effect. Methods A total of 113 cases of radical mastoidectomy with tympanoplasty who were followed up for more than 3 years from 1990 to 1997 were summarized and compared between Open-mastoidectomywith tympanoplasty (OMT) and combined approach tympanoplasty combinedapproachtympanoplasly, CAT) the advantages and disadvantages and long-term efficacy. Results The long-term OMT hearing index was 12dBHL and CAT was 9.5dBHL, with no significant difference between the two groups. OMT was 5.8% and CAT was 24.4% , There is a significant difference between the two. Conclusion The long-term results of this group of patients with OMT surgery is better than CAT surgery.
