Congenital auricular anomalies can be categorized as either malformed or deformational. Auricular deformations most commonly affect the helix and antehelix. Surgical correction involves sutural modeling, wedge excision, reshaping and reversing cartilage segments, and morselization. Since neonatal auricular cartilage is extremely pliable, we used early splinting to correct deformational ear anomalies. Splints were constructed of leadfree, soft soldering wire threaded into polyethylene tubing and held in place with Steri-Strips. From August 1995 through February 1996 we treated 19 infants with 32 deformed auricles: 10 infants were male and 9 were female, ranging in age from 1 day to 10 weeks. Thirteen infants had both ears affected. There were 8 prominent ears, 23 lop ears, 2 Stahl's ears, and 1 infant with an inverted concha. For prominent ears, the helical-mastoid distance decreased from an average of 16.8 to 12.2 mm, after an average of 13 weeks of splinting. Fourteen corrected lop ears had a normal appearance, and 9 were improved with minor residual deformity. There was only one complication: skin irritation requiring adjustment of the prosthesis. Five children had molding started after 3 months of age and all had no significant improvement. In addition, the parents of 5 children refused therapy and 12 children had either poor compliance to therapy or were lost to follow-up. Our experience with auricular molding confirmed that it is easy, effective, and inexpensive. If molded sufficiently early, most auricular deformations should not need surgical correction in childhood.
先天性耳廓畸形可分为畸形或变形两类。耳廓变形最常影响耳轮和对耳轮。手术矫正包括缝合塑形、楔形切除、软骨段重塑和翻转以及碎骨术。由于新生儿耳廓软骨极其柔韧,我们采用早期夹板固定来矫正变形性耳部畸形。夹板由无铅软焊锡丝穿入聚乙烯管制成,并用手术薄膜固定在位。从1995年8月至1996年2月,我们治疗了19例患有32只变形耳廓的婴儿:10例为男性,9例为女性,年龄从1天至10周不等。13例婴儿双耳均受影响。有8只招风耳、23只垂耳、2只斯塔尔耳,还有1例婴儿患有反曲耳甲。对于招风耳,经过平均13周的夹板固定后,耳轮 - 乳突距离从平均16.8毫米降至12.2毫米。14只矫正后的垂耳外观正常,9只有所改善但仍有轻微残留畸形。仅出现一例并发症:皮肤刺激,需要调整假体。5名儿童在3个月龄后开始塑形,均无明显改善。此外,5名儿童的家长拒绝治疗,12名儿童要么对治疗依从性差,要么失访。我们在耳廓塑形方面的经验证实,该方法简便、有效且成本低廉。如果在足够早的时间进行塑形,大多数耳廓变形在儿童期无需手术矫正。
