Most cases are associated with congenital hearing losses. In an ongoing study by NIDCD scientists of more than 100 patients, approximately one-fourth of individuals with EVA and hearing loss were diagnosed with Pendred syndrome. Pendred syndrome is inherited in a traditional autosomal recessive manner as described above. It is the result of two mutations in the SLC26A4 gene. Large vestibular aqueduct syndrome (LVAS) is characterised by sensorineural hearing loss caused by a malformation of the structures of the inner ear.
Large vestibular aqueduct syndrome (LVAS) is thought to be one of the most common congenital causes of sensorineural hearing loss (SNHL). It is usually sudden after head trauma or progressive during childhood. Cochlear implantation is the surgical effective choice of LVAS if marked hearing loss occurred.
