Labyrinthine dehiscence in a child.
A 4-year-old boy presented with moderate to profound mixed hearing loss in the right ear and moderate to severe mixed hearing loss in the left ear, prompting a temporal bone CT scan. Images revealed partial dehiscence of the right posterior semicircular canal. Semicircular canal dehiscence and its associated clinical syndrome have been described in adults. We present this case as a unique finding in a child and discuss the possible clinical and research implications.
