OBJECTIVES: To compare modifications in the surgical technique of congenital aural atresia (use of argon laser, thinner split-thickness skin graft, Silastic sheets in the external auditory canal, and Merocel wicks) by examining hearing results and complications before and after initiation of these changes. STUDY DESIGN AND SETTING: Retrospective chart review of patients who underwent congenital aural atresiaplasty between 1985 and 2002 in a tertiary referral neurotologic private practice. Complication rates and hearing results were compared before (n = 36) and after (n = 80) modifications in the surgical technique. RESULTS: Closure of the air-bone gap to 30 dB or less at short-term follow-up occurred in 63.1% of surgeries performed after modifications in the surgical technique and 44.5% of surgeries performed before these changes. The long-term postoperative air-bone gap was 30 dB or less in 50.0% of the surgeries performed after and 47.1% of the cases performed before the changes in surgical technique. Soft tissue stenosis and bony growth of the external auditory canal were seen in 3.8% of surgeries performed after and 13.9% of surgeries performed before the surgical technique changes. Ossicular chain refixation occurred in 3.8% of surgeries performed after and 25.0% of surgeries performed before such changes. There were no dead ears and no facial palsies. CONCLUSION: The use of argon laser, thinner split-thickness skin graft, Silastic sheets in the external auditory canal, and Merocel wicks, as a group, has helped to improve hearing results and decrease the incidence of complications in congenital aural atresia surgery. SIGNIFICANCE: Refinements in surgical techniques can lead to measurable improvements in outcome in atresiaplasty.
