Summary
This study introduces a keyhole cochlear implantation (CI) technique, minimizing surgical trauma and avoiding traditional fixation methods. This atraumatic approach is safe and effective for all ages, especially infants needing bilateral CI.
Area of Science:
- Otolaryngology
- Neurosurgery
- Biomedical Engineering
Background:
- Traditional cochlear implantation (CI) methods often involve significant soft tissue and bony trauma for implant placement and stabilization.
- Despite advancements in minimalist approaches, surgical refinement for CI remains an area of interest.
Purpose of the Study:
- To present a refined, minimally invasive cochlear implantation technique.
- To evaluate the safety and efficacy of the keyhole CI approach.
Main Methods:
- A restricted-access "keyhole" cochlear implantation technique was developed and utilized in 547 cases.
- The procedure involved a small, 20-mm mini C-incision behind the auricle, omitting bony retention wells and suture fixation.
- Small titanium mesh "bridges" were employed to manage initial implant body migration.
Main Results:
- The keyhole CI technique demonstrated successful implantation with restricted surgical exposure.
- The method eliminated the need for bony wells and suture fixation, preventing wound proximity to the implant and electrode arrays.
- The technique proved to be atraumatic and brief, with no technique-specific complications reported.
Conclusions:
- The keyhole approach offers a less invasive alternative for cochlear implantation.
- This technique is particularly suitable for simultaneous bilateral implantation in infants and adaptable across all age groups.
