Abstract
OBJECTIVE: To compare closure rate, reduction in air-bone-gap, and operative time of butterfly tympanoplasty (BT) to underlay tympanoplasty (UT). METHODS: Retrospective cohort study of children (age <18y) undergoing Type I tympanoplasty between 2009 and 2017. Patients were excluded if they had <6 months of follow up, mastoidectomy, fat graft or cholesteatoma. RESULTS: Twenty-one patients (mean age 13.4) underwent BT while forty-one patients (mean age 13.5) underwent UT. The mean size of perforation in 30.6% in BT patients and 43.6% in UT patients (p = 0.01). Preoperative audiogram showed a similar air-bone-gap between the two groups of 31.7, 22.7, and 17.9 dB in BT vs 29.6, 24.8, and 17.6 dB in UT at 500, 1000, and 2000 Hz, respectively (p = 0.65, 0.63, and 0.94). Operative time was reduced in BT as compared to UT (94.0 min vs. 150.9, p = 0.01). Closure rate was similar at 85.7% in BT vs 75.6% in UT patients (p = 0.40). Average reductions in air-bone gap were similar with 19.2, 11.7, and 13.2 dB for BT vs 16.6, 12.1, and 10.3 dB for UT at 500, 1000, and 2000 hz, respectively (p = 0.66, 0.93, 0.40). CONCLUSION: BT has become a reliable tool for the pediatric otolaryngologist. This retrospective study shows that pediatric BT results in similar outcomes with reduced operative time.
