Objective To investigate the clinical eficacy tympanoplasty plus mastoidectomy in the treatment of chronic suppurative otitis media and cholesteatoma.Methods 72 patients with chronic suppurative otitis media and cholesteatoma patients randomized to the treatment group(n=36)taken tympanoplasty mastoidectomy plus the control group(n=36)a simple line of mastoidectomy,compared to group 2 patient surgery.Results The air-bone gap,air conduction hearing threshold and relapse rates were lower than the control group(P<0.05). ConclusionClinical eficacy of tympanoplasty plus mastoidectomy in the treatment of chronic suppurative otitis media and cholesteatoma certainly worth learning.%目的：探讨乳突根治加鼓室成形术治疗慢性化脓性及胆脂瘤中耳炎的临床疗效。方法将72例慢性化脓性及胆脂瘤中耳炎患者随机分组，治疗组（n=36）采取乳突根治加鼓室成形术，对照组（n=36）单纯行乳突根治术，对比2组患者手术疗效。结果治疗组气骨导差、气导听阈以及复发率均低于对照组（均P＜0.05）。结论乳突根治加鼓室成形术治疗慢性化脓性及胆脂瘤中耳炎的临床疗效肯定。
