Summary
Transcanal endoscopic cochlear implantation offers a safe and feasible alternative for sensorineural hearing loss. This minimally invasive approach shows promising patient outcomes and implant function.
Area of Science:
- Otolaryngology
- Minimally Invasive Surgery
- Audiology
Background:
- Sensorineural hearing loss (SNH) impacts millions globally.
- Traditional cochlear implantation (CI) involves a transmastoid approach.
- Advancements in endoscopic techniques offer potential for less invasive procedures.
Purpose of the Study:
- To evaluate patient outcomes following transcanal endoscopic cochlear implantation (TECI).
- To assess the safety and feasibility of TECI for SNH.
- To compare TECI with the standard open transmastoid approach.
Main Methods:
- Twenty-five TECI procedures were performed on 24 ears in patients aged 7-65 with SNH.
- Exclusion criteria included smaller pediatric patients and obese adults.
- Outcomes measured included implant position, function, and postoperative complications.
Main Results:
- All implants were successfully inserted and functional.
- Mean follow-up was 16 months.
- Minor complications like EAC/TM tears and wound infections were reported but resolved; no facial nerve injury occurred.
Conclusions:
- TECI is a viable, safe, and feasible alternative to the standard open transmastoid approach.
- Endoscopic CI demonstrates good implant function and acceptable complication rates.
- Further research may solidify TECI's role in SNH treatment.
