OBJECTIVE: Establish the time to safely and efficiently perform cochlear implantation (CI) in a university-based academic center. STUDY DESIGN: Case series with chart review. SETTING: Academic neurotologic referral center. PATIENTS: 424 patients who underwent CI surgery between 2002 and 2010. INTERVENTION: Unilateral, bilateral or revision CI using commercially available devices approved for use in the United States. MAIN OUTCOME MEASURES: mean surgical duration (SD) and mean total operative room time (TORT). RESULTS: Overall mean SD for all 424 patients was 83 ± 30 min (min) whereas the mean TORT was 135 ± 56 min. The mean SD for unilateral CI was 84 ± 18 min for the first implant and 82 ± 22 min for the second implant (p=0.55). The SD for primary and revision CI was 83 ± 18 min and 85 ± 36 min, respectively (p=0.51). The mean SD for pediatric and adult CI was 83 ± 21 min and 83 ± 18 min, respectively (p=0.92). The mean SD without resident assistance was 74 ± 14 min whereas with the assistance of a resident the mean SD was 84 ± 20 min (p=0.02). When ossification was encountered the mean SD was 90 ± 32 min compared to 82 ± 19 min when absent (p<0.001). An association was found between TORT or SD, and the year of surgery, presence of ossification and the involvement of an assistant. CONCLUSION: In a university-based academic center, CI surgery can be safely and efficiently performed, supporting future cost-effectiveness analysis of its current practice.
