Introducing SCIP : Service Provision

Cochlear implantation can be partitioned into four phases of patient management.

1. Pre-Implant Assessment

A wide range of tests and investigations are carried out to determine whether individuals are likely to gain more benefit from an implant than conventional acoustic hearing aid(s), possess the physical fitness required for surgery, have the ability to participate in device programming and the cognitive ability to make use of the information provided by an implant.

2. Cochlear Implant Surgery

Cochlear implant surgery is carried out on an inpatient basis and usually involves a 2-3 day stay in hospital. Surgery is required to embed a receiver/stimulator package into a cavity drilled in the mastoid bone and to insert an electrode array into the cochlea. Prior to wound closure, device function and hearing responses are evaluated by electrophysiology.

3. Psychophysics process of stimulating the electrodes

The implant itself is a passive device and can only be activated when the external components of the equipment are worn. The speech processor is the key component of the external equipment. It is issued 4-weeks after surgery. After fitting the speech processor, each electrode is individually tested and activated by appropriate electrical stimuli (psychophysics). Stimulation parameters are optimised and an appropriate processing strategy applied to elicit a meaningful sound sensation. This information is programmed into the speech processor. In the early stages, regular appointments will be required to monitor and adjust these settings. The frequency of these appointments reduces through time. Lifelong scientific support is required.

4. Monitoring Outcomes & Habilitation Support

Outcomes from cochlear implantation lie in the domains of audition, speech, language and education. The rehabilitation professionals from the team work in partnership with the local professionals in monitoring the child’s progress and share outcome information. Habilitation support and advice is provided during the monitoring process. Outcomes are usually monitored for 5 years post-implant. During this time rehabilitation support is gradually reduced. This will vary in accordance with each individual child’s needs.
