This study pools available assessment data (collected prospectively and entered into respective databases from 1990 to 2014) from three Australian centers. Children (n = 403) with congenital bilateral severe to profound hearing loss who received cochlear implants under 6 years of age (excluding those with acquired onset of profound hearing loss after 12 mo, those with progressive hearing loss and those with mild/moderate/severe additional cognitive delay/disability).

Telemedicine (&am... more Telemedicine ("telepractice") allows improved access to specialised early intervention services such as Auditory-Verbal Therapy (AVT) for children with hearing loss. We investigated the effectiveness of a tele-AVT programme (eAVT) in the spoken language development of a group of young children with hearing loss. In a retrospective study we compared the language outcomes of children with bilateral hearing loss receiving eAVT with a control group who received therapy In Person. Seven children in each group (mean age 2.4 years) were matched on pre-amplification hearing level for the better hearing ear, age at optimal amplification and enrolment in the AVT programme. The eAVT sessions were conducted via Skype. Results on the Preschool Language Scale-4 were compared at 2 years post optimal amplification. There were no significant differences in language scores between the two groups. Language scores for the children in the eAVT group were within the normal range for children with normal hearing. The results suggest that early intervention AVT via telepractice may be as effective as delivery In Person for children with hearing loss.

Study Design: Eight children from an auditory verbal intervention program were identified. From a pediatric database, researchers blind to the outcome data, identified 23 children from auditory oral programs and 8 children from bilingualbicultural programs with the same inclusion criteria and equivalent demographic factors. Patients: All child participants were male, had congenital profound hearing loss (pure tone average 980 dBHL), no additional disabilities, were within the normal IQ range, were monolingual English speakers, had no unusual findings on computed tomography/ magnetic resonance imaging, and received hearing aids and cochlear implants at a similar age and before 4 years of age. Main Outcome Measures: Open-set speech perception (consonant-nucleus-consonant [CNC] words and Bamford-Kowal-Bench [BKB] sentences) and the Peabody Picture Vocabulary Test (PPVT) were administered.

Some neurons, such as those in the primary visual area, prune more spines than they grow following sensory onset, while others such as those in area TE grow more than they prune. To what extent these different neuronal growth profiles may vary among cortical areas remains to be determined. To better comprehend the nature and extent of these regional differences in pyramidal cell growth profiles we expanded the bases for comparison by studying neurons in the primary auditory cortex (A1).

AVT This study examined the speech perception, speech, and language developmental progress of 25 children with hearing loss (mean Pure-Tone Average [PTA] 7937 dB HL) in an auditory-verbal therapy program. Children were tested initially and then 21 months later on a battery of assessments. The speech and language results over time were compared xvith those for a control group of children with typical hearing who were matched for initial language age, receptive vocabulary, gender, and socioeconomic level. Speech perception scores for the children with hearing loss showed significant improvement (p < 0.05) for live-voice presentations, but not for recorded voice. For both groups there was significant improvement over 21 months in scores for auditory comprehension, oral expression, total language, and articulation of consonants Dimity Dornan, Ba.Sp.Th., F.S.P.A.A., LSLS Cert.

At the 2i-month test point, 84% of the children with hearing loss scored within the typical range for total language age, compared to 58.6% at the initial assessment. Receptive vocabulary scores xuere an exception, with the children with typical hearing showing significantly more gain than the children with hearing loss (p < 0.05). Nevertheless, the group with hearing loss scored within the typical range for receptive vocabulary. Overall, the results shoxv that the children with hearing loss had improved speech perception skills over time and that their rate of progress for speech and language skills was similar to that of children with typical hearing.
