软骨软骨膜在鼓膜修补中的应用

目的探讨鼓膜大穿孔采用软骨-软骨膜修补的方法及临床疗效。方法36例（40耳）鼓膜大穿孔（软骨-软骨膜组）采用软骨-软骨膜行鼓膜修补术并与同期46例（46耳）颞肌筋膜鼓膜修补术（颞肌筋膜组）进行比较。软骨-软骨膜组采用耳后切口,切取耳廓软骨-软骨膜,然后将软骨切成2～3条,将其相互部分重叠修复穿孔,修补鼓膜,同期行听骨链重建。结果随访1年,软骨-软骨膜组鼓膜穿孔愈合率为95.0%（38/40）;筋膜组鼓膜穿孔愈合率为89.1%（41/46）,两组相比无统计学意义（χ2=0.288,P=0.592）。颞肌筋膜组17耳鼓膜有钙化斑中,5耳穿孔未愈,占29.4%（5/17）;软骨-软骨膜组20耳鼓膜有钙化斑,其中1耳穿孔未愈,占5.0%（1/20）。两组鼓膜有钙化斑的病例鼓膜穿孔愈合率相比有统计学意义（χ2=4.031,P=0.045）。术后1年复查软骨-软骨膜组纯音听力平均气导听阈为36.9dB,平均骨气导差为17.8dB;筋膜组纯音听力平均气导听阈为35.5dB,平均骨气导差为15.9dB。两组比较无统计学意义（t=2.103,P=0.85）。结论软骨-软骨膜修补鼓膜穿孔是一种可靠的方法,其在修补鼓膜大穿孔和鼓膜伴有钙化斑的患者中有一定的优势。

Application of auricular cartilage with perichondrium to myringoplasty

Objective To investigate the methodology and clinical effect of application of auricular cartilage with perichondrium to myringoplasty of patients with large tympanic membrane perforation.Methods Myringoplasty using auricular cartilage with perichondrium as transplant was performed in 36 cases(40 ears)(cartilage with perichondrium group)and that using temporalis fascia was performed in 46 cases(46 ears)(temporalis fascia group).As for the myringoplasty using auricular cartilage with perichondrium as transpl...
