Why Are Pre-Surgery Tests Done?
Pre-operative tests ensure the patient is medically fit for surgery, confirm cochlear implant eligibility, and plan the procedure.
Key Pre-Cochlear Implant Tests
1. Comprehensive Audiological Evaluation
- Repeat pure-tone and speech testing to finalize candidacy.
- For children: Play-based assessments to measure responses to sound.
2. Medical Examinations
- Physical Health Check: Heart, lungs, and anesthesia readiness.
- Ear Exam: Rule out infections, tumors, or abnormalities.
3. Imaging Scans (MRI/CT)
- Purpose: Detailed view of the cochlea and auditory nerve.
- Outcome: Confirms the cochlea’s shape and detects ossification (calcification) that may complicate surgery.
4. Balance Testing
- Why?: Cochlear implants may affect vestibular function.
- Process: Tests like VEMP (Vestibular Evoked Myogenic Potential).
5. Cognitive and Psychological Assessments
- For children: Evaluates readiness for post-surgery therapy.
- For adults: Ensures realistic expectations and commitment to rehabilitation.
Preparation Steps
- Vaccinations: Ensure up-to-date vaccines (e.g., pneumococcal).
- Stop Blood Thinners: To reduce surgery risks.
- Counseling: Discuss risks, benefits, and post-op care.
