Cases of non-cholesteatomatous chronic otits media (COM) were reviewed to determine whether mastoidectomy is helpful when combined with tympanoplasty for these conditions.
A retrospective analysis of 251 ears with non-cholesteatomatous COM operated on by one surgeon (Y.M.) in an 11-year period was conducted.
Patients in group A (n = 147) were treated by tympanoplasty with mastoidectomy. Patients in group B (n = 104) were operated on without mastoidectomy.
Graft success rates were 90.5% in group A and 93.3% in group B. There was no statistically significant difference. Graft success rates of discharging ears were 90.0% in group A and 85.7% in group B. Graft success rates of dry ears were 90.7% in group A and 94.4% in group B. There was no statistically significant difference between discharging ears and dry ears. The rates of the postoperative air-bone gap within 20dB were 81.6% in group A and 90.4% in group B, without a statistically significant difference.
Mastoidectomy is not helpful in tympanoplasty for non-cholesteatomatous COM, even if the ear is discharging.
回顾非胆脂瘤性慢性中耳炎（COM）病例，以确定乳突根治术联合鼓室成形术治疗这些疾病是否有益。
对一位外科医生（Y.M.）在11年期间手术治疗的251例非胆脂瘤性COM患者的耳朵进行回顾性分析。
A组（n = 147）患者接受鼓室成形术联合乳突根治术治疗。B组（n = 104）患者未行乳突根治术。
A组移植物成功率为90.5%，B组为93.3%。无统计学显著差异。A组流脓耳的移植物成功率为90.0%，B组为85.7%。A组干耳的移植物成功率为90.7%，B组为94.4%。流脓耳和干耳之间无统计学显著差异。A组术后气骨导差在20dB以内的比例为81.6%，B组为90.4%，无统计学显著差异。
对于非胆脂瘤性COM，即使耳朵流脓，乳突根治术在鼓室成形术中也无帮助。
