Objective(1) Characterize a large cohort of patients undergoing total ossicular chain reconstruction with titanium prosthesis. (2) Analyze long-term hearing outcomes of the same cohort.Study DesignCase series with chart review.SettingTertiary care center.Subject and MethodsThis study reviews patients who underwent total ossicular chain reconstruction (OCR) with titanium prostheses (TORPs) at a single tertiary care center from 2005 to 2015. Patient charts were reviewed for demographic data, diagnosis, and operative details. Patients were included in statistical analysis if length of follow-up was 2 years or more. Evaluation of hearing improvement was made by comparing preoperative air-bone gap (ABG) and ABG at follow-up at 2 years.ResultsIn total, 153 patients were identified who met inclusion criteria. The mean age of included patients was 40 years (range, 6-89 years). Sixty patients (39%) had a history of OCR, and 120 patients (78%) had a diagnosis of cholesteatoma at the time of OCR. Preoperatively, the mean ABG was 36 ± 12, whereas the mean ABG at 2-year follow-up improved to 26 ± 13. This was statistically significant ( P < .0001) using a Wilcoxon matched-pairs signed rank test. Twelve patients (8%) required revision OCR. Two revisions were performed due to prosthesis extrusion (<1%).ConclusionTitanium prostheses lead to significant improvement in hearing over long periods. The results are sustained as far out as 5 years following surgery. In addition, rates of revision surgery with titanium TORPs are low. Based on this series, there are no readily identifiable predictors for outcomes following total OCR.
