“…The age hearing loss was first suspected was around 4.3 years old, mostly the child's mother and the medical diagnosis was usually made at the age of 6 years, similar data to those reported in other studies 1,2,5,12 . Although has a neonatal hearing screening program in Brazil, late detection of hearing problems, usually during preschool age, is still common, especially in case children at risk to hearing loss 5,13 . 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.…”

“…Many investigators have studied the etiology of unilateral hearing loss 3,4 and the most frequent causes of hearing loss are complications of viral infections and meningitis, especially in developing countries where these diseases are still very common. 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 .…”

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.

“…Compared with bilateral cases, inner ear anomaly and mass lesions are more frequently seen in unilateral hearing loss. In the study by Laury et al [12] 8 of 11 patients had cochlear nerve aplasia, and 2 patients had a mass lesion. In another study, the rate of inner ear anomaly was found to be 66.7% [19] .…”

“…Because inner ear anomalies and mass lesions are more common risk factors for USNHL than bilateral hearing loss, computed tomography (CT) and magnetic resonance imaging (MRI) investigations are necessary [12] .…”

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.
