What
Cochlear implantation is used for severe to profound sensorineural hearing loss. The system consists of an external speech processor and an internal receiver-stimulator and electrode array. The surgery is usually performed with the aid of a microscope or endoscope, with a postauricular approach to implant the electrode through the round window or fenestration into the cochlea, fix the receiver, and perform intraoperative electrophysiological testing. Postoperative monitoring of wound and facial nerve function is performed, followed by activation programming and auditory training. The above is general health information, not medical advice; the specifics are subject to specialist assessment and hospital protocols.
How
- After anesthesia, the surgery begins with a postauricular approach.
- The electrode array is implanted into the cochlea through the round window or fenestration.
- Fix the receiver and perform intraoperative electrophysiological testing.
- Postoperative monitoring of wound and facial nerve function.
Recovery
After surgery, pay attention to wound cleaning and dryness, and avoid external pressure on the magnet area of the implant; seek medical attention if persistent vertigo, bleeding, or fever occurs. Initial activation and subsequent tuning are carried out according to the center's plan, and auditory and speech rehabilitation is carried out step by step. Flying is generally possible after recovery is stable; it is recommended to carry the implant card and follow the manual inspection process when passing through security checks. MRI examination requires prior declaration of the implantation and compliance with equipment specifications.
- Keep the wound clean and dry, and avoid external pressure.
- Follow the plan for initial activation and auditory rehabilitation.
- Follow implantation-related instructions before flying and MRI.
FAQ
Is long-term follow-up required?
Yes. Regular tuning and auditory/speech assessment are usually required to optimize the user experience; the specific frequency is carried out according to the center's plan.
Can I do strenuous exercise or swim?
It can be carried out after the wound has healed and with the doctor's permission; the external processor needs to use protective/waterproof accessories or be removed, following the manufacturer's and hospital's recommendations.
How soon after surgery can I "hear"?
Sound perception usually begins after activation and basic tuning, and adaptation and recognition take time to train; the specific arrangements and rhythm are determined by the hospital and rehabilitation team.
What discomfort may occur after surgery?
Local swelling, pain, or transient vertigo are common and mostly relieved with recovery; if symptoms are obvious or persistent, a follow-up visit should be made in time.
Can I have an MRI or pass through security checks?
MRI can be performed in compliance with equipment and hospital specifications, and may require specific modes or accessories. It is recommended to carry the implant card and cooperate with manual inspection when passing through security checks.
Are accessories and batteries included in the cost?
Subject to the hospital's official quotation list. Some accessories and subsequent upgrades and consumable replacements may be charged separately.
Is rehabilitation different for children and adults?
Rehabilitation strategies will be adjusted according to age, previous auditory experience, and family cooperation, and the frequency and duration are determined by the team's assessment.
Can bilateral implantation be performed simultaneously?
It is feasible in some centers, depending on hearing status, communication needs, rehabilitation resources, and cost arrangements, and the path is determined after specialist assessment.
