Abstract

Objective:

This review aimed to summarise present knowledge surrounding cochlear implants and neuroplasticity using positron emission tomography.

Overview:

Cochlear implants are an established device for severe sensorineural hearing loss. However, the outcomes following a cochlear implant are variable and unpredictable. Furthermore, despite increasing numbers of implantations taking place, there are still uncertainties regarding how individuals learn to process speech using an implant. Functional neuroimaging studies using techniques such as positron emission tomography provide an insight into the cortical changes that take place in patients with cochlear implants.

Conclusion:

Only when the underlying mechanisms responsible for speech processing in implantees are understood can appropriate rehabilitation for those with poor speech perception be provided and outcomes improved.
