Abstract
Background: Electric stimulation of the auditory nerve via cochlear implants has made a great
impact on treatment of sensory deafness. Advanced signal processing and stimulation
paradigms have led to continuously improved results in speech understanding. Consequently,
indication criteria have been extended to patients with profound and severe-to profound hearing
loss and limited speech understanding with conventional acoustic amplification.
Aim: The aim of this study was to present speech development in subjects with pre-lingually
sensorineural hearing loss implanted with a cochlear implant in Republic of Macedonia.
Methods: The study included 31 subjects of both sexes and pre-lingual sensorineural hearing
impairment. The average age of the implanted patients was 100.4 ± 74.1 months. The speech
perception after cochlear implantation was evaluated using the Monosyllabic-Throche Polysyllabic test (MTP) with closed-set words without the aid of lip-reading. The patients should be able to point-to or clearly repeat the pictured words (or objects). Subjects were followed-up in a period of 6, 12 and 24 month post-implantation.
Results: Cochran’s Q-test showed a significant difference in identification of monosyllabic,disyllabic and polysyllabic words in patients with cochlear implant during the analyzed period of
24 months. McNemar’s test confirmed that 24 months after implantation the subjects significantly better identified monosyllabic, disyllabic and polysyllabic words in comparison with the time interval at 12 and 6 months. Also, there was a substantial improvement 12 months after
cochlear implantation in comparison with the interval at 6 months.
