Abstract

Abstract: Introduction: Myringoplasties are common pediatric procedures used to surgically close a perforated tympanic membrane. While a wide variety of graft materials are available to surgeons, the cost effectiveness of these different techniques is not well studied. Objectives: To compare the cost effectiveness of the fat graft myringoplasty (FGM) with the hyaluronic acid fat graft myringoplasty (HAFGM). Methods: Retrospective chart review of patients ages 31 days to 18 years who had undergone either FGM or HAFGM from 2006 to 2016. Results: We identified 85 patients who had undergone FGM and 51 patients who had undergone HAFGM. The two groups were statistically similar in age (CI -0.51, 1.9; p = 0.23), sex (CI 0.3, 1.4; p = 0.27), and history of prior tympanostomy tube placement (CI -0.07, 0.07; p = 0.69). Both groups had a similar number of total comorbidities (40.0% of patients in the FGM group and 27.5% of patients in the HAFGM; CI -0.04, 0.29; p = 0.19). The FGM and the HAFGM procedure did not have statistically significant differences in perforation closure rates, 82.4% and 92.2% respectively (CI 0.81, 7.3; p = 0.13). In comparing the total surgeons' cost of closing a tympanic membrane deficit, the FGM incurred a greater cost per perforation. The cost/tympanic membrane perforation closure for the FGM totaled $3011.88 per deficit, whereas the HAFGM totaled $2742.98. Conclusion: As financial stewardship becomes more important for medical decision making, it is imperative that providers consider cost and outcomes data together when comparing similar treatment options. The FGM and the HAFGM have statistically similar rates of success in closing tympanic membrane perforations. In this study, the FGM cohort consumed more health care dollars per perforation secondary to the need for revision surgeries. As such, this study offers that the additional use of a hyaluronic disc does not increase overall cost to the healthcare system when performing a fat graft myringoplasty over a large cohort of patients.
