Molding therapy for infants with deformational auricular anomalies

Abstract

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.
