Summary
Preoperative imaging using computed tomography (CT) and magnetic resonance imaging (MRI) is standard for cochlear implant surgery globally. MRI aids diagnosis, while CT is preferred for surgical planning, enhancing patient safety and outcomes.
Area of Science:
- Otolaryngology
- Neurosurgery
- Radiology
Background:
- Preoperative imaging is essential for cochlear implant surgery.
- It aids in diagnosis and planning surgical interventions.
Purpose of the Study:
- To evaluate global practices in preoperative imaging for cochlear implantation.
- To assess the perceived value and risks of different imaging modalities.
Main Methods:
- A cross-sectional survey was conducted among international cochlear implantation experts.
- A 112-item questionnaire explored imaging modalities, targets, parameters, and perceived value/risks.
Main Results:
- 39 practitioners from 16 countries participated.
- Computed tomography (CT) and magnetic resonance imaging (MRI) are universally used.
- MRI is valued for diagnosis; CT for surgical planning.
- 79.5% use image-based surgical planning software.
Conclusions:
- CT and MRI are indispensable for cochlear implant evaluations.
- MRI supports diagnosis, CT aids surgical planning.
- Evolving imaging techniques may enhance protocols and patient outcomes.
