This study aimed to compare outcomes for mastoidotympanoplasty and for tympanoplasty alone in cases of quiescent, tubotympanic, chronic, suppurative otitis media.
Single-blinded, randomised, controlled study within a tertiary referral hospital.
Sixty-eight cases were randomly allocated into two groups. In group one, 35 ears underwent type one tympanoplasty along with cortical mastoidectomy. In group two, 33 ears underwent type one tympanoplasty alone. Outcome measures were as follows: perforation closure and graft uptake, hearing improvement, disease eradication, and post-operative complications.
There were no statistically significant differences in hearing improvement, tympanic perforation closure, graft uptake or disease eradication, comparing the two groups at three and six months post-operatively.
Mastoidotympanoplasty was not found to be superior to tympanoplasty alone over a short term follow-up period. Hence, it may not be necessary to undertake routine mastoid exploration at this stage of disease.
本研究旨在比较在静止期、咽鼓管鼓室型慢性化脓性中耳炎病例中行乳突鼓室成形术与单纯鼓室成形术的疗效。
在一家三级转诊医院进行的单盲、随机对照研究。
68例患者被随机分为两组。第一组，35耳接受了I型鼓室成形术及皮质骨乳突切除术。第二组，33耳仅接受了I型鼓室成形术。观察指标如下：穿孔闭合及移植物吸收情况、听力改善情况、疾病根除情况及术后并发症。
术后3个月及6个月时，比较两组患者的听力改善、鼓膜穿孔闭合、移植物吸收或疾病根除情况，均无统计学显著差异。
在短期随访期内，未发现乳突鼓室成形术优于单纯鼓室成形术。因此，在疾病的这一阶段可能无需进行常规乳突探查。
