Abstract

Abstract: Objective: to evaluate the changes in daily voice production, analysed through the Ambulatory Phonation Monitoring (APM), and their relationship with Quality of Life (QOL) measurements in a group of profound deaf patients treated with Cochlear Implant (CI). Methods: A total of 12 consecutive post-lingual deaf patients (8 females and 4 males) treated with CI for bilateral severe-to-profound hearing loss were enrolled. Each patient was evaluated before and after 6 months of CI use. In particular, the daily voice production evaluation was performed using the APM, while QOL information were gathered from the Italian version of the Nijmegen Cochlear Implant Questionnaire (I-NCIQ). Results: Significant differences in the APM results obtained before and after CI were found. In particular, a significant decrease of the mean amplitude and a significant increase of the daily phonation time and percentage of phonation time were demonstrated after CI use in all the patients. A significant improvement in the I-NCIQ scores was demonstrated after CI use and significant correlations among I-NCIQ scores and the APM parameters were found. Conclusions: The APM could be useful in the evaluation of the benefits of cochlear implantation and may represents an indicator of deaf patient participation. In addition, the daily voice production's modifications after CI and their significant relations with the changes in QOL measurements could be useful in treatment planning as well as during pre- and post-operative counselling.
