Comparison of early speech perception in cochlear-implant patients with and without early fitting
The early fitting of adulted cochlear-implant patients at day 3 post-operatively was well received by most of the patients. Therefore, we want to investigate the influence of direct early fitting to early speech understanding in comparison to patients without direct early fitting.
Based on a questionnaire n = 69 patients with direct activation were interviewed regarding the handling of the technique and their speech perception. Speech test results were obtained on day 1 before and on day 5 after the regular fitting 4 weeks post-operatively. For comparative statements of speech test results between patients with and without early fitting we build matched-pairs groups.
Patients with direct activation get along well with the handling of the technique. Speech perception is subjectively assessed as sufficient. The average speech test results showed from day 1 to day 5 significant improvement among monosyllables from 17% to 36% and among sentence test in noise from 5% to 17%.
The comparison of the speech test results between patients with and without direct activation shows higher results for patients with direct activation in monosyllable discrimination by 3% and speech understanding in noise by 5%.
Patients with early fitting cope with the handling of the technique and appreciate the speech perception already enough. They have slight higher speech understanding as patients without early fitting after regular fitting. A professional CI rehabilitation after 4 weeks post-operatively ensures the hearing success in both groups.
