Summary
This study developed a predictive model for cochlear implant (CI) surgery duration, identifying factors like patient gender, age, and surgical approach. The model aids in optimizing operating room management and patient care.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Engineering
Background:
- Cochlear implantation (CI) is a complex procedure with variable operative durations.
- Accurate preoperative estimation of surgical time is crucial for efficient operating room management and resource allocation.
Purpose of the Study:
- To develop a predictive model for estimating cochlear implant (CI) operative duration.
- To identify independent clinical and procedural factors influencing CI surgical time.
Main Methods:
- Retrospective observational study of 216 cochlear implant patients.
- Surgical time (skin incision to wound closure) was the primary outcome.
- Generalized linear models (univariate and multivariate) were used to identify predictors of surgical duration.
Main Results:
- Factors influencing surgical time included patient gender, age, implantation laterality, surgical approach (round window), and surgical team composition.
- Male gender, unilateral implantation, and the round window technique were associated with shorter surgical times.
- Older age and the involvement of a consultant/fellow/resident team were associated with increased surgical duration.
Conclusions:
- A predictive model for CI operative duration was successfully developed.
- This model can enhance operating room management and personalize patient care plans in CI surgery.
- The identified factors provide valuable insights for surgical planning and training.
