OBJECTIVES: Rates of success with pediatric myringoplasty range from 35 to 95%. The objective of this study is to evaluate the impact of perforation size on successful closure of the tympanic membrane (TM) after gelfoam myringoplasty. We also aim to identify variables that affect perforation closure rates and define predictive factors for successful TM closure.
METHODS: A retrospective chart review of all patients that underwent gelfoam myringoplasty by a single surgeon from August 2008 through January 2015 was performed.
RESULTS: One hundred fifty-nine patients met inclusion criteria and underwent a total of 219 procedures. Overall, gelfoam myringoplasty had an 83.1% rate of successful closure. Average perforation size was 15.31%. Classification tree analysis separated our cohort into three groups based on perforation size: Group 1 (<16.25%) had a 91% closure rate, group 2 (16.25% to <31.25%) had a 66.0% closure rate and group 3 (≥31.25%) had a 30.0% closure rate. Smaller perforations (P ≤0.001) were associated with increased success rates. Other factors associated with successful closure of the TM included younger age at the time of myringoplasty (P ≤0.001), fewer number of prior tympanostomy tubes (P = 0.016), and lesser duration of tube retention (P = 0.003).
CONCLUSION: Gelfoam myringoplasty provides good overall TM closure rates and may be considered as a potential first-line option for repair of perforations, including those involving up to 40% of the TM. Younger patients with smaller perforations, fewer sets of tubes, shorter length of tube retention are more likely to have successful closure of the tympanic membrane.
