Seventy four simple myringoplasties, 53 with xenograft and 21 with fresh temporalis fascia were reviewed. Closure rate for all cases was 90.5%. There were 3 surgical failures in xenografts and none in the fascia graft. Fifty two myringoplasties, 37 using xenograft and 15 using fascia graft, had a mean follow-up of 20 months and late perforations were seen in 4 of these cases. Three of the late reperforations occurred in xenografts, one in the fascia graft. Postoperative air bone gap was within 15 dB in 83.3% of the xenografts and in 66.7% of the fascia grafts. Recurring bouts of granular myringitis after 6 months were seen in 4 xenografts and in one fascia graft. Based on these results xenograft can be considered as an alternative for fresh fascia in easy to reach perforations operated "in speculo" when there is no need for an external incision.
回顾了74例单纯鼓膜成形术，其中53例使用异种移植物，21例使用新鲜颞肌筋膜。所有病例的闭合率为90.5%。异种移植物中有3例手术失败，筋膜移植物无失败病例。52例鼓膜成形术，37例使用异种移植物，15例使用筋膜移植物，平均随访20个月，其中4例出现晚期穿孔。3例晚期再穿孔发生在异种移植物中，1例发生在筋膜移植物中。83.3%的异种移植物和66.7%的筋膜移植物术后气骨导差在15dB以内。4例异种移植物和1例筋膜移植物在6个月后出现复发性颗粒性鼓膜炎。基于这些结果，当不需要外部切口时，对于易于到达的“耳镜下”操作的穿孔，异种移植物可被视为新鲜筋膜的替代物。
