The aim of this study was to analyze the outcome of inlay "butterfly" cartilage tympanoplasty.
The files of 42 patients (24 were male, 18 were female) who underwent primary or revision inlay butterfly cartilage tympanoplasty in 2005 to 2011 at a tertiary medical center were reviewed. Patients were regularly observed by otoscopy and audiometry.
The mean patient age was 27 years (range, 14-75 years), and the mean duration of follow-up was 24 months (range, 3-36 months). The postoperative period was uneventful. The technical (anatomical) success rate was 92% at 1 year. There was a significant decrease in the mean air-bone gap in 32 patients (preoperatively, 49.6 dB; postoperatively, 26.2 dB; P = .006). Results were suboptimal in 3 patients with persistent small perforations of the operated ear.
Inlay butterfly cartilage tympanoplasty appears to be effective in terms of defect closure and improved hearing, comparable with temporalis fascia graft tympanoplasty. Follow-up is necessary for at least 1 year when some perforation may reappear.
本研究旨在分析嵌合式“蝴蝶”软骨鼓室成形术的疗效。
回顾 2005 年至 2011 年在一家三级医疗中心接受原发性或修正性嵌合式蝴蝶软骨鼓室成形术的 42 例患者（24 例男性，18 例女性）的档案。患者定期接受耳镜和听力检查。
患者平均年龄为 27 岁（14-75 岁），平均随访时间为 24 个月（3-36 个月）。术后情况平稳。术后 1 年的技术（解剖）成功率为 92%。32 例患者的平均气骨导间隙显著降低（术前 49.6dB，术后 26.2dB；P=0.006）。3 例患者术后持续出现小面积手术耳穿孔，疗效欠佳。
嵌合式“蝴蝶”软骨鼓室成形术在封闭缺陷和改善听力方面似乎是有效的，与颞肌筋膜移植物鼓室成形术相当。当某些穿孔可能再次出现时，需要至少 1 年的随访。
