Summary
A novel double array cochlear implant increases intracochlear electrodes in obliterated cochleas. This specialized implant significantly improves auditory results and speech understanding for patients with severe hearing loss.
Area of Science:
- Otolaryngology
- Biomedical Engineering
- Neuroscience
Context:
- Cochlear implants are vital for hearing restoration.
- Obliterated cochleas present surgical challenges for electrode insertion.
- Advanced implant designs are needed to overcome anatomical limitations.
Purpose:
- To evaluate a novel double array cochlear implant for obliterated cochleas.
- To assess the feasibility and efficacy of increased electrode insertion.
- To improve auditory outcomes in patients with severe hearing loss.
Summary:
- A specialized double array cochlear implant was developed with two electrode carriers (11 and 10 electrodes) for obliterated cochleas.
- Surgical technique involved creating two cochleostomies for electrode insertion into the first and second cochlear turns.
- Ten patients (32-66 years) with obliterated cochleas received the implant; all showed improved speech understanding without complications.
Impact:
- The double array implant successfully increases intracochlear electrode count in obliterated cochleas.
- Patients experience significantly enhanced auditory performance and speech understanding.
- This technology offers a viable solution for hearing restoration in complex cochlear anatomies.
