title: [Sudden deafness with large vestibular aqueduct (case report and literatures review)].
abstract: OBJECTIVE
  To study the clinical feature of large vestibular aqueduct syndrome and diagnostic basis of large vestibular aqueduct on high resolution computer tomography.
  
  
  METHODS
  Report a 18 year old man who presented a sudden deafness in right ear and his left ear arised the same disorder before 11 months. Since childhood his both ears have occurred sensorineural hearing loss, which causations were reserved unknown. The temporal bone axially oriented high resolution computer tomography scanning showed a enlarged vestibular aqueduct without associated cochlear anomalies of both ears. In addition the literatures about this disorder are reviewed.
  
  
  RESULTS
  The large vestibular aqueduct syndrome without association cochlear anomalies may occurs acquired sensorineural hearing loss and appears to be at high risk for sudden deafness.
  
  
  CONCLUSIONS
  It is important to identify followed by high-resolution computer tomography whether a large vestibular aqueduct syndrome when a causal uncertain sensorineural hearing loss or/and a sudden deafness onset in childhood is represented.
