To evaluate the efficacy of fasciaform myringoplasty as a means to repair large tympanic membrane perforations in children.
Retrospective review of the records of 26 patients who underwent 29 consecutive fasciaform myringoplasty surgeries over a 47-month period. Patients were followed up from 2 to 47 months postoperatively.
Academic tertiary care children's hospital.
Twenty-six patients (5 to 16 years old), with tympanic membrane perforations (25% to 95%) underwent a fasciaform myringoplasty procedure. The perforations were caused by extrusion of ventilation tubes (83%), deep retraction pockets, trauma, or repair after resection of cholesteatoma.
The surgery involves resection of the native tympanic membrane and annulus. A new tympanic membrane is formed from formaldehyde-fixed autogenous temporalis fascia and positioned.
Successful repairs, complications, and audiometric evaluations were analyzed. Fisher's Exact Test was used to compare complication rates by age.
Successful closure was accomplished in 69% of cases. Otitis media recurred in 52%. Ventilation tubes were reinserted in 24%; 28% resolved with antibiotics alone. When tubes were placed through the graft, small residual graft perforations resulted. Audiometric evaluation revealed improvement in pure tone average to less than a 20-dB hearing level in 77% and reduction of the air-bone gap to within a 20-dB hearing level in 90% of those cases (10/29) with complete audiometric data.
Fasciaform myringoplasty has proven to be a successful procedure for closing large tympanic defects and improving hearing acuity in the pediatric population. However, recurrent otitis media and eustachian tube dysfunction may continue. Rates of reperforation were statistically significantly higher in children 7 years old and younger. Conservative management of children in this younger age group is warranted.
评估筋膜成形鼓膜成形术修复儿童大鼓膜穿孔的疗效。
回顾性分析26例患者在47个月内连续接受29次筋膜成形鼓膜成形术的手术记录。术后对患者进行2至47个月的随访。
学术性三级儿童医院。
26例年龄在5至16岁之间、鼓膜穿孔(25%至95%)的患者接受了筋膜成形鼓膜成形术。穿孔原因包括通气管脱出(83%)、深部回缩袋、外伤或胆脂瘤切除术后修复。
手术包括切除原鼓膜和鼓环。用甲醛固定的自体颞肌筋膜形成新的鼓膜并进行定位。
分析成功修复情况、并发症及听力评估结果。采用Fisher精确检验比较不同年龄组的并发症发生率。
69%的病例成功闭合。52%的患者中耳炎复发。24%的患者重新插入了通气管;28%的患者仅用抗生素治疗后病情缓解。当通气管穿过移植物插入时,移植物出现小的残余穿孔。听力评估显示,在有完整听力数据的病例中(29例中的10例),77%的患者纯音平均听阈改善至低于20dB听力水平,90%的患者气骨导差缩小至20dB听力水平以内。
筋膜成形鼓膜成形术已被证明是一种成功的手术方法,可闭合儿童大鼓膜缺损并提高听力。然而,中耳炎复发和咽鼓管功能障碍可能仍然存在。7岁及以下儿童的再穿孔率在统计学上显著更高。对于这个年龄较小的儿童群体,保守治疗是必要的。
