Summary
Lateral petrosectomy offers a viable surgical approach for cochlear implantation in patients with chronic otitis media. This technique allows for successful electrode insertion, even with cochlear obliteration, and avoids postoperative complications.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Facial recess approach is standard for cochlear implantation in normal anatomy.
- Alternative surgical approaches are needed for complex cases like chronic otitis media or cochlear obliteration.
Observation:
- Authors report on lateral petrosectomy for cochlear implantation in two patients with chronic otitis media.
- Both patients underwent successful insertion of all cochlear implant electrodes.
Findings:
- The lateral petrosectomy technique is well-established and was effectively applied for cochlear implantation.
- No postoperative complications were observed in the treated patients.
- This approach provides excellent access to the cochlea, particularly the basal turn, facilitating electrode insertion even with scala tympani obliteration.
Implications:
- Lateral petrosectomy is a feasible and safe surgical option for cochlear implantation in patients with chronic otitis media.
- This approach expands the possibilities for cochlear implantation in challenging anatomical conditions.
- Further studies may validate the long-term efficacy and safety of this technique.
