“…Patients typically realise they have hearing loss in primary school with the help of their teacher, or while talking on the phone or listening to music using earphones. Besides having low academic performance in school, affected children may also show difficulties in understanding conversations in a noisy environment [7][8][9] .…”

OBJECTIVE:The aim of this study was to evaluate the vestibular system of children with unilateral sensorineural hearing loss (USNHL), investigate the etiological factors of USNHL and analyze whether a genetic predisposition exists. MATERIALS and METHODS:Thirty-three children aged less than 18 years with USNHL, who visited the ear, nose, and throat (ENT) department between January 2004 and December 2012, were included in this study. Cases with conductive hearing loss were excluded from the study. The patients were subjected to etiologic, genetic, and ophthalmologic evaluation; radiologic imaging; electronystagmography (ENG); and vestibular evoked myogenic potential (VEMP) tests. The control group, which included 25 healthy children (13 males and 12 females), had undergone audiological assessment and were subjected to ENG and VEMP tests. RESULTS:All of the patients had severe-to-profound hearing loss. Mumps immunoglobulin G was positive in 22 (66.7%) of 33 patients. The 35delG mutation was not found in any of the patients. All of the patients underwent temporal computed tomography (CT) and magnetic resonance imaging (MRI). Inner ear anomaly was present in 51.5% of the patients. Overall, 21 of 31 ENG patients had canal paresis in the affected ear. The VEMP response was absent on the affected side in three patients. The n23 latency average of the patient group was longer than that of the control group. CONCLUSION:Because USNHL causes irreversible problems in children, early diagnosis and auditory rehabilitation are very important. As USNHL is accompanied by inner ear anomaly, children with USNHL should undergo temporal bone CT and MRI. To evaluate the vestibular system, ENG and VEMP are non-invasive and diagnostic tests.

“…Because the vestibular system may also be affected in cases with USNHL, imbalance and vertigo may also be present [1] . All of these negative effects may manifest in low academic performance, difficulties in social life, and lack of self-confidence [3,[7][8][9][10][11] .…”

“…A good neonatal hearing screening program provides an opportunity for early detection and intervention in children allowing parents to anticipate potential difficulties during language development and at school. The earlier the diagnosis, the more effective is intervention and rehabilitation, reducing hearing-related impairments 4,7 . The main impact of the symptoms of hearing impairment reported by parents and/or caregivers were those associated to school activities, especially for the learning of reading and/or writing and on the patient behavior.…”

“…Cochlear nerve aplasia also appears to be commonly related do unilateral sensorioneural hearing loss 5 . Hearing problems experienced by individuals with unilateral hearing loss are in part due to the phenomenon of binaural hearing, which includes binaural summation, sound localization and threshold change by masking noise 4,6-8. Health specialists have point out that a great deal of children with unilateral hearing loss has behavioral and/or school problems compared to those with normal hearing 4,6,7 . They also report that these children experience emotional disorders such as embarrassment, confusion, annoyance, and call .…”

The aim of study is to verify the association with oral communication disorders and unilateral sensorioneural hearing loss. Based on a preliminary cross-sectional study including 20 subjects, both females and males between seven and 19 years old (mean 10.8) with varying degrees of unilateral sensorineural hearing loss who attended a speech and language therapy service in São Paulo, Brazil. All patients underwent anamnesis, auditory evaluation, and a standard structured interview to collect information about their language, communication and auditory performance. In general subjects were diagnosed with hearing loss at mean age of 6.3 years. Five (25%) of these subjects had a history of school failure and hearing loss in the left ear. The most common communication disorders reported were associated to oral communication. Language, communication and auditory performance was affected by varying degrees of unilateral hearing loss and comorbidities as lack of attention, irritability and agitation are associated to communication disorders resulting from unilateral hearing loss in this sample.

The 22q11.2 deletion syndrome is caused by non-allelic homologous recombination events during meiosis between low copy repeats (LCR22) termed A, B, C and D. Most patients have a typical LCR22A-D (AD) deletion of 3 million base pairs (Mb). In this report, we evaluated IQ scores in 1,478 subjects with 22q11.2DS. The mean of full scale IQ, verbal IQ and performance IQ scores in our cohort were 72.41 (standard deviation-SD of 13.72), 75.91(SD of 14.46) and 73.01(SD of 13.71), respectively. To investigate whether IQ scores are associated with deletion size, we examined individuals with the 3 Mb, AD (n = 1,353) and nested 1.5 Mb, AB (n = 74) deletions, since they comprised the largest subgroups. We found that full scale IQ was decreased by 6.25 points (P = 0.002), verbal IQ was decreased by 8.17 points (P = 0.0002) and performance IQ was decreased by 4.03 points (P = 0.028) in subjects with the AD versus AB deletion. Thus, individuals with the smaller, 1.5 Mb AB deletion have modestly higher IQ scores than those with the larger, 3 Mb AD deletion. Overall, the deletion of genes in the AB region largely explain the observed low IQ in the 22q11.2DS population. However, our results also indicate that haploinsufficiency of genes in the LCR22B-D region (BD) exert an additional negative impact on IQ. Furthermore, we did not find evidence of a confounding effect of severe congenital heart disease on IQ scores in our cohort.
