Summary
Immediate cochlear implant activation (IA) is feasible and does not negatively impact hearing outcomes. This approach, with careful follow-up, offers comparable results to classical activation (CA) for patients with hearing loss.
Area of Science:
- Otolaryngology
- Biomedical Engineering
- Audiology
Background:
- Cochlear implantation is a critical treatment for severe to profound hearing loss.
- Traditional cochlear implant activation occurs weeks after surgery.
- Investigating earlier activation protocols may optimize patient outcomes.
Purpose of the Study:
- To evaluate the feasibility and audiological outcomes of immediate cochlear implant activation (IA).
- To compare IA with classical activation (CA) at 2 weeks post-implantation.
Main Methods:
- Retrospective study of 29 patients (19 IA, 10 CA).
- Comparison of speech audiometry at 6 months, implant fitting, and complication rates.
- Statistical analysis using the Student t-test.
Main Results:
- No significant difference in speech comprehension or intelligibility thresholds between IA and CA groups at 6 months.
- Comfort-level settings in IA remained stable post-activation.
- One IA patient experienced a hematoma requiring delayed activation; no other complications reported.
- Similar numbers of fitting sessions were required for both groups.
Conclusions:
- Immediate cochlear implant activation is a feasible option.
- IA does not compromise audiometric results compared to CA.
- Careful patient monitoring is essential for successful IA.
