Which cross-over frequency is best for electro-acoustic stimulation?
Advances in technology and improved soft surgical techniques have led to individuals with better hearing thresholds, especially at the low frequencies, becoming candidates for cochlear implants (CI). Surgeons are more confident that residual hearing can be preserved thus making those...
Effect of stimulation levels on speech recognition and auditory threshold performance
When programming a Cochlear® device, two measurements are normally assessed. T levels relate to the quietest sound the CI user can hear i.e. thresholds, and C levels are comfortable levels which are tolerable for the CI user. If these levels...
Recording of electrode voltages (REVS) to determine extra-cochlear electrodes
Determining whether electrodes are sitting within the cochlea can be difficult as the checks run by the programming software cannot always determine this. In some cases, patients may be unable to give the audiologist detailed feedback which can complicate the...
Robotic insertion of electrode array in cochlear implantation
Cochlear implants (CIs) are commonly used for profound bilateral hearing loss. They have specific national guidance for their insertion, however patients with a substantial residual acoustic hearing are potential CI candidates. Preservation of this residual hearing can be sought with...
How common is dysphonia and dysphagia after cardiac surgery?
Patients undergoing cardiac surgeries, such as coronary artery bypass (CABG) and valve operations, are usually informed that there may be some risk of laryngeal complications that could result in a dysphonia or dysphagia. This may be due to factors including...
