改良完壁式乳突切除术及鼓室成形术治疗慢性中耳乳突炎的疗效分析

目的:探讨改良完壁式乳突切除术及鼓室成形术治疗慢性中耳乳突炎的疗效。方法:对72例慢性中耳乳突炎患者行改良完壁式乳突切除术及鼓室成形术的治疗过程进行分析及总结。结果:术后观察患者6个月,胆脂瘤型、骨疡型、混合型术后气导、骨导平均听阈均显著大于术前;骨疡型术后听力改善比例最高,改善率为84.0%,其次为胆脂瘤型,改善率为71.0%,混合型最差,改善率为62.5%。3个月内全部干耳。结论:改良完壁式乳突切除术及鼓室成形术治疗慢性中耳乳突炎既能彻底清除病灶,又能尽可能地保留与中耳传声功能相关的组织结构,可早日干耳,提高听力。

Efficacy analysis of improved wall mastoidectomy and tympanoplasty for chronic otitis mastoidea

Objective: To investigate efficacy of improved wall mastoidectomy and tympanoplasty for chronic otitis mastoidea.Methods: Characters of wall mastoidectomy and tympanoplasty in 72 patients with chronic otitis mastoidea that underwent the surgery were analyzed.Results: Patients were observe for 6 months,improvements in hearing threshold for patients ascribed as cholesteatoma type,bone lesion type and mixed type were significant greater than before undergoing the operation,of which the maximum improvements was observed in cholesteatoma type patients(84.0%),which was followed by bone lesion type(71.0%) and mixed type(62.5%).Within 3 months after undergping the operation,all secretions disappeared in all these patients.Conclusion: Improved wall mastoidectomy and tympanoplasty can remove lesions and reserve the organizational structure of the middle ear transmission,it also can help to dry ear and improve hearing.
