Bony cochlear or vestibular malformations occur in about 20% of patients with congenital sensorineural hearing loss. Intuitively, one would expect such malformations to influence surgical and audiologic outcomes in patients undergoing cochlear implantation. However, the precise impact of these malformations on surgical and audiologic outcomes has not yet been elucidated.

The aim of this study was to examine whether variables known to impact communication outcomes for full-term children using CIs (who have sensorineural hearing loss as their single diagnosis), would have the same impact on preterm children using CIs. Specifically, it was hypothesized that preterm children with longer gestational age, greater birth weight, lesser cognitive delay, more residual hearing, shorter duration of profound loss, communication mode with an aural/oral emphasis, larger electrical dynamic range, less difficulty with mapping and programming, higher socioeconomic status (SES), and younger age of implantation would demonstrate better speech perception and language outcomes.

A 10-year-old nonverbal Greek boy, C.Z., who had been
diagnosed with both bilateral sensorineural profound hear-
ing loss and autism, was taught to use the Picture Exchange
Communication System (PECS), with some modifications and
extensions, over a 4-month intensive intervention period. C.Z.’s
original communication and behavioral status as well as the
PECS application process are presented, along with the
communicative, language, and psychosocial outcomes follow-
ing the intervention program. Follow-up data were collected
6 months post.
Little research has focused on the coexistence of hearingloss and autism in children (Gillberg & Steffenburg,1993; Gordon, 1991; Jure, Rapin, & Tuchman, 1991).
Epidemiological studies reveal higher comorbidity rates than
would be expected in the general population (Gordon; Jure
et al.). As Konstantareas and Homatidis (1987) reported, au-
ditory peculiarities and abnormalities in children with autism
have often been noted, yet no systematic and reliable data have
been collected on the frequency of hearing loss or peripheral
ear problems in this population. Generally, hearing problems
are reported more frequently in people with neurological and
developmental disorders than in those without such diagnoses
(van Schrojenstein Lantman-de Valk, 1997). Autism has also
been reported to occur more often in children with viral-
related diseases known to affect hearing, such as congenital ru-
bella (Chess, 1971) and congenital cytomegalovirus infection
(Stubbs, Ash, & Williams,1984).
The prevalence of autism is 30–40 cases in 100,000 (i.e.,
0.3%–0.4%; Rutter, 2005) while the prevalence of hearing loss
in the general population under 45 years of age is 4% (Nadol,
1993) and 2% of newborn infants experience bilateral hearing
loss with 0.7% in the moderate to profound range (Conn-
Wesson et al., 2000). Based on these studies, it can be con-
cluded that the incidence of hearing loss in children with
autism, as well as the incidence of autism in children with hear-
ing loss, is greater than the one found in typically developing
populations. Jure et al. (1991) found that 61 out of 1,150 chil-
dren with hearing impairments met the criteria for a diagnosis
of autism, or 5.3% of the population of individuals with hear-
ing impairments. In another Swedish study, Rosenhall, Nor-
din, Sandstrom, Ahlsen, and Gillberg (1999) reported on au-
diological examinations of 199 children with autism; 7.9% of
them were found to exhibit mild to moderate hearing loss, and
3.5% had severe or profound hearing losses.
Despite the high comorbidity of autism and hearing loss,
few studies have used complete audiometrical battery tests
(i.e., combined measures of pure tone audiometry and tym-
panometry) to assess the hearing status of children with autism
(Smith, Miller, Stewart, Walter, & McConnell, 1988). The
small number of studies may be explained by the observation
that hearing assessment is very difficult in cases of combined
autism and hear.
The risk of cognitive impairment assosiated with congenital deafness in child...MaritLobben
Overall poor performance of cognitive and behavioral skills are predictors of poor language skills and vice versa: we need to realise that language, perception, thought, and problem-solving constitute a continuum of interdependent functions.
Some refer to this as polymodal development of the sensory apparatus, as the developing trend in typically developing individuals (Bailey, 2002).
Sensory input participates not only in a simple additive way but also has a reciprocal influence in that it modulates synergistically the unyielding of neural networks.
This is probably why children with deafness exhibit subtle differences from hearing subjects also in functions that seem far removed from the auditory function, such as visuomotor integration or abstract thinking.
From a neuroscientific perspective, this is an interesting demonstration in relation to the extent of the role of hearing in the building of neural networks that result from sensorimotor exposure and practice.

Of the 415 children in the study (195 girls and 220 boys; mean [SD] age, 363.0 [8.3] days), a consistent association between craniofacial shape and prenatal alcohol exposure was observed at almost any level regardless of whether exposure occurred only in the first trimester or throughout pregnancy. Regions of difference were concentrated around the midface, nose, lips, and eyes. Directional visualization showed that these differences corresponded to general recession of the midface and superior displacement of the nose, especially the tip of the nose, indicating shortening of the nose and upturning of the nose tip.
Differences were most pronounced between groups with no exposure and groups with low exposure in the first trimester (forehead), moderate to high exposure in the first trimester (eyes, midface, chin, and parietal region), and binge-level exposure in the first trimester (chin).
CONCLUSIONS AND RELEVANCE Prenatal alcohol exposure, even at low levels, can influence craniofacial development. Although the clinical significance of these findings is yet to be determined, they support the conclusion that for women who are or may become pregnant, avoiding alcohol is the safest option.

There is evidence that this efferent control may play a role in extracting signals from noise and the detection of target sounds.

We hypothesized that both the ABRs and OAEs would be modulated by attention and that the degree of suppression of OAEs (relative to the passive condition) would increase with task difficulty.

Introduction
Results - Adults
Bony cochlear or vestibular malformations occur in about 20% of patients with congenital
sensorineural hearing loss. Intuitively, one would expect such malformations to influence Table 3: Outcomes in Adults by Type of Congenital Malformation
surgical and audiologic outcomes in patients undergoing cochlear implantation. However,
the precise impact of these malformations on surgical and audiologic outcomes has not
yet been elucidated.
Patients and Methods
A retrospective review of the Cochlear Implant Clinic database at the University of
Melbourne identified 57 children and 31 adults with cochlear and/or vestibular
malformations who had undergone cochlear implantation. The patients’ CT and MRI scans
were classified into ordinal categories of cochlear malformation according to the scheme
of Sennaroglu1: common cavity (CC), incomplete partition -I (IP-I); IP-II with or without
enlarged vestibular aqueduct (EVA); IP-III, or EVA alone.
Duration of profound hearing loss was significantly correlated with OSW Word (r=-0.36,
Analysis of variance (ANOVA) was used to compare speech perception (open-set word, p=0.04) and BKB Sent (r=-0.41, p=0.02), but not with OSW Phon (r= -0.27, p=0.14), .

Test (PPVT) standard scores and delay), and surgical outcomes (occurrence of a CSF Table 4: Outcomes in Adults with Gushers and Incomplete Insertions
gusher and insertion depth) among the groups of malformations. Pearson’s correlation
coefficients were calculated between the duration of profound hearing loss and speech
perception and language outcomes. T-tests were used to compare speech perception and
language outcomes between groups of patients with and without gushers and incomplete
electrode insertions. SPSS5 was used to perform all statistical analyses.

Discussion
Pre-operative imaging is a routine and essential part of planning cochlear implantation.
However, based on this retrospective study of children and adults , the extent of pre-
operative cochlear/vestibular malformation alone cannot predict post-operative cochlear
implant performance (Tables 1 and 3).
On the other hand, the presence of gusher, incomplete insertion and a longer duration of

insertion, precluding meaningful statistical comparison (Table 4)
The post-operative speech and language scores in the present study are similar those
Table 2: Outcomes in Children with Gushers and Incomplete reported in other pediatric groups with cochlear abnormalities but lower than those with
Insertions normal cochlea and adult groups.2-4
One of the limitations of this study is the significant number of patients who did not have
complete post-operative speech perception and language testing. For example, 2 of the
patients with common cavities, 5 of those with IP-II + EVA and 2 of those with EVA alone
performed too poorly to test OSW. This may contribute to the failure of this study to show
performance differences between groups of different malformations. On the other hand,
the patients with these malformations who were tested performed well, underscoring the
wide range of outcomes that we observed within all groups of malformations
