PurposeIn 1998, Dr. Eavey described the trans-canal inlay butterfly cartilage tympanoplasty technique, also known as cartilage button tympanoplasty. Many retrospective studies have since demonstrated its efficacy and decreased operative time when compared to underlay and overlay tympanoplasty techniques. The butterfly cartilage tympanoplasty approach uses only a cartilage graft to repair tympanic membrane perforations. The aim of this study was to review the literature for studies that examined butterfly cartilage tympanoplasty success rates and outcomes and compare them to outcomes from our cohort.Materials and methodsButterfly cartilage tympanoplasties were performed in 23 pediatric patients and 7 adult patients. We evaluated the tympanic membrane perforation closure rate and hearing results measured by closure of the air-bone gap.ResultsThe reviewed studies evaluating butterfly cartilage tympanoplasties demonstrated perforation closure rates between 71%–100%. The hearing outcomes in the reviewed literature varied, although the majority reported improved hearing. In our cohort, 21 of the 32 repaired tympanic membrane perforations demonstrated complete perforation closure. The mean follow-up length was 13.4 months. The mean air-bone gap decreased from 13.4 dB to 6.9 dB.ConclusionsThe butterfly cartilage/cartilage button technique is effective in closing tympanic membrane perforations and decreasing the air-bone gap in both adults and children.
