13Bringing It Together: The Preparation Checklist
Every preceding step in this chapter, the medical work-up, the vaccination, the counselling, the consent and the expectation-setting, converges on a single reproducible pathway from decision to theatre. This closing module assembles those threads into one operational checklist, so that nothing load-bearing is left to memory. A good checklist is not bureaucracy; it is the mechanism by which a multidisciplinary team guarantees that the right patient arrives at surgery medically fit, fully immunised, properly consented and realistically prepared.
FThe pathway, owned by the team
The pre-operative pathway runs as a fixed sequence: referral, team meeting, core audiological assessment, functional/live-voice hearing testing, speech-language assessment, psychological assessment, optional special tests, ENT decision with CT/MRI review, and a final pre-implant consultation before theatre. Each item on the checklist has a named owner. The multidisciplinary team — surgeon, audiologist, hearing therapist, speech-language therapist, clinical psychologist, nurse, teacher of the deaf and social worker — distributes responsibility so that no single gate depends on memory or goodwill. A dedicated nurse or nurse practitioner should own vaccination oversight, reviewing records monthly and confirming status back to the surgical team; one programme used this structure to raise paediatric pneumococcal vaccination from 67% to 98%. Ear selection is its own checklist decision, driven by shorter duration of deafness, higher residual speech discrimination and anatomy; in bilateral-candidate adults the ear with better discrimination or shorter deafness is prioritised.[2006][2006][2006][2018]
CHard medical gates: fitness, imaging, vaccination
Medical and anaesthetic clearance is a gate, not a formality: every candidate needs documented fitness for elective general anaesthesia, and active respiratory infection, fever or instability postpones surgery. All children require a 12-lead ECG to screen for Jervell and Lange-Nielsen long-QT syndrome before theatre. Imaging review is mandatory and cannot be skipped because anatomy looks routine; CT/MRI must be read for inner-ear malformation and post-meningitic ossification, the latter able to begin within 3–21 days of meningitis and to preclude insertion if surgery is delayed. Pneumococcal vaccination (PCV plus PPSV23) must be given at least 2 weeks before surgery; in adults a single PCV15/20/21 dose is followed by PPSV23 at least 8 weeks later, and Hib vaccine is added only for children under 5 years. The vaccination gate exists because implant recipients carry roughly a 138-fold elevated incidence of pneumococcal meningitis, and 6 of 10 documented post-operative meningitis cases in malformed ears occurred alongside an intraoperative CSF leak.[2006][2003][2003][2023]
CConsent with honest numbers
Consent should quote real frequencies, not generalities: facial-nerve stimulation occurs in 2.9–5.3% of recipients (up to 14.9% in otosclerosis, ~46% manageable by reprogramming), and post-operative facial palsy in only 0.67–1.2%. Common nuisance complications must be named with their recovery data — taste change affects ~45% (about 81% recover, mean 20 weeks) and abnormal caloric vestibular responses appear in ~49% at 14 months, yet 74% report no dizziness handicap. Lower-frequency but serious risks belong on the consent checklist too: CSF gusher in ~1% of procedures (usually managed with brief packing), post-implant meningitis in ~0.7%, and the irreversible loss of any residual hearing in the implanted ear. Candidates should also hear the upside in concrete terms: pre-existing tinnitus improves ~58% in loudness by 24 months, and modern soft-surgery preserves measurable residual hearing in around 92% of recipients early after surgery.[2018][2007][2021][2025]
CCalibrating expectations and family readiness
Realistic expectations are rated by clinicians as the single most important non-audiological factor in deciding to proceed; about 42% of candidates hold expectations that exceed their 12-month outcomes, and lower pre-operative expectations track with higher post-operative quality of life. The checklist must capture family commitment, especially in children: rehabilitation is a years-long process of regular mapping, follow-up and active communication work, and family readiness is a documented prerequisite for proceeding. Counselling should set the timeline honestly — comprehensive understanding is not present at activation, early sensations may feel unfamiliar or overwhelming, and benefit builds over weeks to months as the brain adapts to electrical stimulation. Group-specific expectations belong on the checklist: only 44% of prelingually deaf adults reach ≥50% word intelligibility at one year, while children implanted before 18 months end up only ~8 points below hearing peers versus ~39 points if implanted after 36 months.[2021][2006][2006]
