| Research Abstract |
We classified progressive or delayed onset hearing loss in the early childhood. We investigated deafness gene mutation and congenital cytomegalovirus infection of progressive or delayed onset hearing loss children, and in addition, analyzed OTOF of a child with auditory neuropathy. Some of them had enlarged vestibule aqueduct, and one of them had SLC26A4 mutation. There were children who had diagnosis of congenital cytomegalovirus infection, but someone deteriorate their hearing in early childhood without any risk factors. A case with auditory neuropathy didn't have OTOF gene mutation. We started the screening of deafness gene mutation by the invader method in our hospital in December, 2009, and we need to increase cases and investigate them more in the future.
