Summary
Cochlear implantation is safe and effective in patients with radical mastoidectomy cavities. Obliterating the cavity ensures satisfactory hearing outcomes and prevents complications like electrode extrusion.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Radical mastoidectomy cavities can pose challenges for cochlear implantation.
- Previous middle ear surgery may complicate auditory rehabilitation.
Purpose of the Study:
- To evaluate the safety and efficacy of cochlear implantation in patients with prior radical mastoidectomy.
- To assess hearing outcomes and complication rates in this specific patient group.
Main Methods:
- Retrospective review of 6 postlingually deafened adults who underwent cochlear implantation in radical mastoidectomy cavities.
- Evaluation of speech performances including bisyllabic word recognition, sentence recognition, and common phrase comprehension.
Main Results:
- No cases of electrode extrusion or local/intracranial complications were observed over a 1-9 year follow-up.
- Mean bisyllabic word recognition was 74%, sentence recognition was 80%, and common phrase comprehension was 86%.
Conclusions:
- Obliterating and isolating radical mastoidectomy cavities allows for safe cochlear implantation.
- Satisfactory hearing results can be achieved in patients with a history of radical middle ear surgery.
