Summary
The transcanal approach offers an effective, time-saving method for cochlear implantation (CI) in select patients. This technique is particularly useful for those with abnormal temporal bone structures or chronic otitis media (COM).
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Devices
Background:
- Cochlear implantation (CI) is a critical treatment for severe hearing loss.
- Traditional CI approaches can be challenging in patients with complex temporal bone anatomy or chronic otitis media (COM).
- Novel surgical techniques are needed to improve CI outcomes in these specific patient populations.
Purpose of the Study:
- To introduce and evaluate the efficacy of the transcanal approach for cochlear implantation (CI).
- To assess the suitability of this method in patients with abnormal temporal bone structures or chronic otitis media (COM).
Main Methods:
- Retrospective review of six patients undergoing CI via the transcanal approach.
- Surgical technique involves electrode insertion through the external auditory canal (EAC) after tympanomeatal flap elevation and cochleostomy.
Main Results:
- The transcanal approach was successfully employed in all six patients.
- Three patients had a history of inactive COM.
- Difficulties with the transmastoid approach due to anatomical variations (e.g., vascular anomalies, narrow aditus, displaced sigmoid sinus) were noted in other patients.
- No serious postoperative complications were reported.
Conclusions:
- The transcanal approach is a viable and effective surgical option for cochlear implantation (CI).
- This method can be particularly advantageous for selected CI candidates with challenging temporal bone anatomy or COM.
- The transcanal approach may offer a time-saving benefit in these specific cases.
