Abstract
Objective: To summarize current knowledge on the indications, surgical strategies, and auditory outcomes of revision stapes surgery (RSS) for otosclerosis.
Data sources: The search was conducted in PubMed, Scopus, and Web of Science online databases, including papers published since 2000.
Review methods: The study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. We considered original series describing RSS for otosclerosis, reporting postoperative hearing outcomes according to the American Academy of Otolaryngology-Head and Neck Surgery guidelines for conductive hearing loss (CHL) for at least 30 consecutive cases. The quality of included studies was assessed with the Joanna Briggs Institute checklist. Pooled proportion and odds ratio (OR) meta-analysis were conducted using random effect models.
Results: Nineteen studies were included, for a total of 2602 patients (2735 ears) and 2359 postoperative hearing results. RSS was mostly performed for recurrent CHL with air-bone gap (ABG)>20 dB. Multiple concomitant causes were often present, with prosthesis placement defect and incus necrosis as the most common causes. The pooled proportion of postoperative ABG<10 dB and ABG<20 dB was 57.2% (95% confidence interval [CI]: 52.8%-61.4%) and 79% (95% CI: 76.0%-81.8%), respectively. Dead ears were 1.2% (95% CI: 0.7%-2.1%). Compared to primary surgery, RSS had a significantly lower rate of ABG<10 dB (OR = 0.36, 95% CI: 0.24%-0.54%; P < .001). Both revision incudostapedotomy with/without incus reconstruction and malleovestibulopexy are viable options with nonsignificant differences in ABG closure rates (P = .182).
Conclusion: RSS is challenging and requires the surgeon to carefully evaluate all potential causes of previous failure and tailor the intervention according to intraoperative findings. In most cases, ABG closure within 20 dB can be achieved with a relatively low risk of dead ears.
期刊介绍：
Otolaryngology–Head and Neck Surgery (OTO-HNS) is the official peer-reviewed publication of the American Academy of Otolaryngology–Head and Neck Surgery Foundation. The mission of Otolaryngology–Head and Neck Surgery is to publish contemporary, ethical, clinically relevant information in otolaryngology, head and neck surgery (ear, nose, throat, head, and neck disorders) that can be used by otolaryngologists, clinicians, scientists, and specialists to improve patient care and public health.
