Article / Publication Details First-Page Preview Abstract The majority of patients with large vestibular aqueduct syndrome (LVAS) present with progressive sensorineural hearing loss. [karger.com]

Large vestibular aqueduct syndrome was present in approximately 12% of children who presented with congenital sensorineural hearing loss. [ edit ] Imaging Findings for Large vestibular aqueduct syndrome A dilated vestibular aqueduct can be easily recognized [radswiki.net]

The two most common mutations, T416P and IVS8+1G>A, were present in 22% and 30% of families, respectively. [experts.umich.edu]

Her tympanograms were normal on the day she presented to us. In the right ear, she had acoustic reflexes present at 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz, whereas on the left, acoustic reflexes were present at 500 Hz and 1000 Hz only. [audiologyonline.com]

• Nasal Congestion

  If you have EVA, you can minimize your risk of hearing loss associated with air travel by taking nasal decongestants if you have sinus or nasal congestion, such as during a cold or flu. [nidcd.nih.gov]

As part of a more comprehensive workup, he was referred for outpatient MRI. Findings A brain and internal auditory canal protocol was utilized given history of chronic hearing loss and dizziness. No prior studies were available for correlation. [radiologytoday.net]

Additional measurements we include in our clinical workup will become very important. [audiologyonline.com]

Prognosis Patients with PDS may have progressive hearing loss, although it is not yet possible to identify these patients in advance. [orpha.net]

Just as the cause(s) of EVA remain unclear, much of what is known about it, e.g. why the hearing loss pattern differs among patients, how many people actually have it, how it causes symptoms, how to effectively treat it, and what the prognosis might be [vestibular.org]

Carrying out an appropriate audiological and aetiological differential diagnosis when faced with this finding can provide greater perisurgical safety and better knowledge of the physiopathology, clinical evolution and prognosis of some SNHLs. [elsevier.es]

We believe that parental stress is reduced and the child's hearing impairment better accepted when we give thorough information on the cause and prognosis of hearing loss for the child and family members. [adc.bmj.com]

Dilated vestibular aqueduct is a common etiology of neurosensory hearing loss. It is diagnosed when the transverse diameter is greater than or equal to 1.5 mm. [advancedradteaching.com]

Although variants in this gene are not the only cause of hearing loss with EVA, SLC26A4 contributes significantly to this etiology. [personalizedmedicine.partners.org]

Etiology Biallelic or double heterozygous genetic mutations are identified in about half of patients: biallelic mutations in SLC26A4 (7q31), or double heterozygous mutations in SLC26A4 and FOXI1 (5q34), or in SLC26A4 and KCNJ10 (1q23.2). [orpha.net]

Summary Epidemiology PDS is one of the most frequent forms of syndromic genetic deafness. Although prevalence is unknown, PDS may account for up to 7.5% of cases of congenital hearing loss. [orpha.net]

As already commented, the only epidemiological association is the greater presence of IAC alterations in syndromic children, as is the case with this patient. [elsevier.es]

While there is no cure, early hearing loss detection and care may help prevent total deafness. Hearing loss from vestibular dilation can be detected by MRI, magnetic resonance imaging, or CT, computed tomography, of the inner ear. [methodistsouthlake.com]
