Cochlear Implant in a Child With Acquired Deafness

Abstract

The auditory training course of a 3-year 5-month-old child with acquired deafness who received a Nucleus 22 channel implant is reported. Soon after switching it on, her response was not very clear.There was good subsequent progress in auditory discrimination, whereas the patient's major communication strategy preoperatively had been manual, lip-reading, and written language. Her vowel discrimination score reached 100% in 8 months.The patient's articulation and speech intonation has also improved, and her auditory reception of environmental sounds has also shown relative improvement.

Emotional Perception of Music in Children With Bimodal Fitting and Unilateral Cochlear Implant

“…[10][11][12] Furthermore, by provision of bilateral hearing, patient's hearing skills can be improved. Among these skills that stand to gain are: better and clearer speech perception, 10,13 reduction in the negative effect of background noise in speech perception, a possible reduction in fatigue and deterioration in HL, 12 better localization skills, 11,14 increase in the dynamic range, feeling the balance of hearing, 15 and an improvement in perception of music. 15,16 However, in some cases, the results were contradictory and expected impact of binaural hearing was not observed.…”

It is worth noting that bimodal hearing, in addition to being achieved by the aforementioned strategy of prescribing separate hearing aids and CIs in both ears, is feasible through the hybrid method, which combines hearing aid and CI prostheses in 1 ear.…”

“…2 After birth, an infant first perceives tones of speech before learning the actual vowels and consonants of native language. 15 In addition, the brain regions responsible for language and music perceptions are located adjacent to each other and even overlap in some cases. 18,19 Thus, activity in 1 of these regions can affect the other's perception.…”
