OBJECTIVE: This study aimed to compare surgical and audiometric outcomes of tympanoplasty alone (T) to tympanoplasty and mastoidectomy (T&M) in patients without cholesteatoma.
DATABASES REVIEWED: According to PRISMA guidelines, English articles in PubMed, Scopus, CINAHL, and Cochrane Library databases from inception to 7/29/2021 were searched.
METHODS: Studies describing a comparison of patients who underwent T to patients who underwent T&M were included. Studies describing patients with cholesteatoma were excluded. Patient demographics, graft failure rates, and preoperative and postoperative audiological findings were collected. Mean differences (MD) and risk difference (RD) were calculated using RevMan 5.4. Heterogeneity was assessed using Q test and I2 statistic. Risk of bias was assessed using both version 2 of the Cochrane risk-of-bias tool for randomized trials and Risk of Bias in Non-randomized Studies of Interventions.
RESULTS: A total of 27 studies fulfilled eligibility with T (n = 1,711) and T&M (n = 1,186). When pooling the data, mean differences between T versus T&M for air bone gap (-0.3 dB: 95% CI = -1.9 to 1.3, p = 0.730) and pure tone average (1.9 dB: 95% CI = -0.3 to 4.2, p = 0.090) were not statistically significant. Graft failure was higher with T only (16.4% versus 14.2%) than T&M (RD = -0.04, 95% CI = -0.07 to -0.00, p = 0.030, I2 = 35%].
CONCLUSION: This study endorses clinically similar audiological outcomes and a reduced risk difference of graft failure with mastoidectomy. Although these data suggest that adding a mastoidectomy could decrease the risk of graft failure, the risk reduction is minimal. More research on the cost-effectiveness and the specific patient clinical characteristics and comorbidities that would benefit from adding a mastoidectomy is warranted.
