Balance function following cochlear implantation

Imbalance is a risk of cochlear implantation. This is particularly important in patients receiving bilateral implants, who are often children. 25 adult and pediatric patients undergoing cochlear implantation were tested pre-operatively and post-operatively using tests of balance function. Results showed moderate losses in some test paradigms following implantation in the patient group as a whole. While changes in balance function due to cochlear implantation are not uncommon, their practical effect on function may be minor.

Efficacy of the Speech Intelligibility Index as an intervention tool with pediatric cancer patients

This study evaluates the Speech Intelligibility Index (SII) as a tool to describe hearing loss and predict when hearing aids would be appropriate for pediatric oncology patients who have received or are currently receiving cisplatin. The efficacy of the SII is compared to the Brock grade which is commonly used for patients with ototoxic hearing loss secondary to cisplatin treatment. The SII is a discrete measure that precisely reflects the patient’s functional hearing status and is highly correlated with the need for audiologic intervention.
