Sumario: | OBJECTIVE: To systematically review the results of inlay cartilage butterfly tympanoplasty and standard underlay temporal fascia tympanoplasty for anatomic and functional end points. DATA SOURCES: PubMed, Embase, MEDLINE, and Virtual Health Library (VHL/Lilacs) databases were searched from inception through April 2, 2021. No restrictions on language, publication year, or publication status were applied. REVIEW METHODS: The meta-analysis included data from articles that met inclusion criteria and were extracted by 2 authors independently. The PRISMA statement was followed. Risk of Bias 2.0 and Newcastle-Ottawa Scale were used to assess risk of bias. The primary outcome was tympanic membrane closure rate. The secondary outcome was improvement of the air-bone gap. RESULTS: Ten studies were included, 9 cohort studies and 1 randomized clinical trial, with 577 patients. The graft take rate was 82.8% in the butterfly cartilage inlay tympanoplasty group and 85.2% in the temporal fascia underlay tympanoplasty group (relative risk, 1.01; 95% CI, 0.93-1.11; I(2) = 42%, P = .08). The air-bone gap reduction ranged from 6.1 to 11.28 in the butterfly cartilage inlay group and from 5.2 to 12.66 in the temporal fascia underlay group, with a mean difference between groups of −2.08 (95% CI, −3.23 to −0.94; I(2) = 58%, P = .04), favoring temporal fascia underlay. CONCLUSION: The 2 tympanoplasty techniques analyzed here produced similar results in terms of successful reconstruction of the tympanic membrane and reduction in the air-bone gap. Neither age nor follow-up length of time influenced outcomes. |
