Abstract

Objective: Few studies have examined operative times for cochlear implantation (CI) using multivariable linear regression analyses to identify predictors of case length. Herein, we assess whether trainee participation, among other factors, influences operating room (OR) times. Methods: We retrospectively reviewed total OR and procedural times for isolated unilateral implants over a 5-year period (2009–2013) in children and adults. Total operating and procedural times were compared. Multivariable linear regression analyses were used to identify predictors of procedural time. Results: We identified a total of 455 unilateral CI procedures (n = 35 pediatric, n= 420 adult). Mean total OR time was 193.6 minutes (SD = 58.9 minutes) and mean procedural time was 147.1 minutes (SD = 56.2). The presence of trainees was associated with a significant difference in procedure time: 149.9 minutes (SD = 54.9) with trainees versus 136.6 minutes (SD = 59.9) without trainees, P = 0.0375. Trainee involvement did not significantly increase total OR time: 196.3 minutes (SD = 56.9) with trainees versus 183.8 minutes (SD= 65.0) without trainees, P = 0.0653. Surgeon identity was also associated with differences in procedural time (P < 0.001). Patient age, gender, American Society of Anesthesiologists classification, and pediatric designation had no significant impact on length of case. Conclusions: Major predictors of longer procedural OR times for CI are surgeon identity and trainee participation. Few published data exist on length of CI in an academic setting using multivariable linear regression analyses. Our data may be instructive for comparative analyses and have implications for operative planning and surgical education.
