Staging of tympanoplasty is important in the management of patients with chronic otitis media. It allows establishment of an air-containing middle ear space and adequate postoperative hearing levels in a large proportion of patients with severely diseased ears. The results of 400 staged procedures performed over a 3-year period at the House Ear Clinic, Los Angeles are reported. Staging was performed in 75% of tympanoplasty with mastoidectomy cases and in 15% of ears not requiring mastoid surgery. Closure of the air-bone gap to 20 dB or less occurred in 68% of patients with intact stapes. Mucous membrane problems were the most common reason for staging. Almost one third of cases with middle ear cholesteatoma at the first stage had residual disease on reexploration. Staging of tympanoplasty continues to be an important technique in management of severely diseased ears.
鼓室成形术的分期对于慢性中耳炎患者的治疗很重要。它能在很大比例的耳部疾病严重的患者中建立含气的中耳腔并达到足够的术后听力水平。本文报告了在洛杉矶耳科诊所3年期间进行的400例分期手术的结果。75%的鼓室成形术伴乳突切除术病例以及15%不需要乳突手术的耳朵进行了分期。镫骨完整的患者中，68%的气骨导差缩小至20dB或更小。黏膜问题是分期的最常见原因。第一阶段患有中耳胆脂瘤的病例中，近三分之一在再次探查时有残留疾病。鼓室成形术的分期仍然是治疗严重耳部疾病的一项重要技术。
