Objective:
To compare postoperative complications between staged versus unstaged tympanoplasty and subtotal petrosectomy (STP) in adults undergoing cochlear implants with noncholesteatoma chronic otitis media (NCCOM) and tympanic membrane perforation.
Databases Reviewed:
PubMed/MEDLINE, Cochrane CENTRAL, Embase, CINAHL, Web of Science, WHO Global Index Medicus, ClinicalTrials.gov, and WHO ICTRP.
Materials And Methods:
A systematic search of databases was conducted by a research librarian from inception through November 18, 2024. Eligible studies for inclusion must have reported on adult cochlear implant recipients undergoing surgical management of NCCOM with perforation. Using a random effects model, complication rates were pooled and compared between staged and unstaged surgeries using relative risk (RR) with 95% CI.
Results:
Of 1265 studies identified, 19 met inclusion criteria (n = 84). Fifty three (63.1%) patients underwent unstaged surgery. Amongst all patients, STP was performed more than tympanoplasty (72.6%, 61/84 vs 27.4%, 23/84), and the overall complication rate was 11.9% (10/84). There was no significant difference in complication rates between combined staged and unstaged surgeries [RR: 1.13 (95% CI, 0.18-7.04)] as well staged and unstaged tympanoplasty [RR: 0.34 (95% CI, 0.11-0.1.01)]. However, complication rates were lower for staged than unstaged STP [RR: 0 (95% CI, 0.0-0.07)].
Conclusion:
Staged and unstaged surgery for NCCOM and cochlear implant may result in comparable complication rates, however the wide CIs for RR statistics in comparisons between combined staged and unstaged procedures as well as staged and unstaged tympanoplasty indicate a need for similar studies of larger populations.
