“…Collectively, the finding from this systematic review and meta-analysis is consistent with recent individual studies conducted in past 8 years (8,9,37,41,52,53), which finds that there are no statistically significant differences between the postoperative hearing outcomes of wet and dry ears. One theoretical reasoning explaining this is that a tympanic membrane perforation affects the conductive pathway of hearing regardless of whether the ear is wet or dry.…”

“…Thirty-three studies (7–13,18–22,24–44) were included to analyze the outcomes and seven studies (7–13) were included for the meta-analysis. Twenty studies (60.6%) were undertaken in India, three studies (9.1%) in China, two studies (6.1%) each in Thailand and Bangladesh, and one study (3.0%) each in Korea, Nepal, Iraq, Italy, Egypt, and Pakistan.…”

“…23 studies recruited patients with dry ear status (11,18–22,24–29,31–33,35,36,38–40,42–44), three studies with wet ear status (30,34,37), and 7 studies with both dry and wet ear status (7–10,12,13,41). Some studies only included microscopic myringoplasty (7–10, 12,13,18–21,24,26,31–33,35,37,40–42), some only endoscopic myringoplasty (27,28,30,34,38,44) and some included both types (11,19,20,24–31). The underlay technique was used in all studies, with 4 studies also using the overlay technique (21,24,29,32).…”

Postoperative Outcomes After Tympanoplasty for Active Versus Inactive Otitis Media Patients With Tympanic Membrane Perforation: A Systematic Review and Meta-Analysis

2023

View full text Add to dashboard Cite

Objectives To compare postoperative tympanoplasty outcomes between active versus inactive otitis media (OM) patients with tympanic membrane perforation. Databases Reviewed Medline via PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and Google Scholar for studies published from inception to March 1, 2023. Methods Studies of 15- to 60-year-old patients undergoing microscopic/endoscopic myringoplasty using underlay/overlay technique with reported postoperative mean hearing gain and graft uptake were included. Studies requiring simultaneous surgical procedures, reporting patients with comorbidities and with non-English full text articles were excluded. Articles were independently screened by two researchers with data extracted according to a predetermined proforma in Microsoft Excel. Cochrane risk-of-bias assessment was used for risk of bias evaluation of randomized studies and Risk of Bias in Nonrandomized Studies of Interventions for nonrandomized studies. Similar studies were pooled for meta-analysis using the inverse variance random effects model to calculate the mean difference and corresponding 95% confidence interval (CI) for mean hearing gain and DerSimonian and Laird random effects model for graft uptake. Results Thirty-three studies comprising 2,373 patients met the inclusion/exclusion criteria, seven were pooled for meta-analysis. Included articles showed inactive OM patients have higher average postoperative mean hearing gain of 10.84 dB and graft uptake of 88.7% compared to active OM patients (9.15 dB and 84.2%). Meta-analysis of mean hearing gain (MD, –0.76 dB; 95% CI, −2.11 to 0.60; p = 0.27, moderate certainty) and graft uptake (OD, 0.61; 95% CI, 0.34–1.09; p = 0.10, moderate certainty) have an overall p value >0.05. Conclusion There were no statistically significant differences in postoperative mean hearing gain and graft uptake between active and inactive OM patients undergoing tympanoplasty. Hence, tympanoplasty procedures should not be postponed solely because of patients' preoperative ear discharge status.
