Prelingual non-syndromic genetic hearing loss

A rare, genetically highly heterogeneous otorhinolaryngologic disease, resulting from inner and/or middle ear or hearing nerve anomalies, typically characterized by bilateral, severe to profound hearing loss (mean sensorineural hearing impairment of 60 dB or more for 500-, 1,000-, and 2,000-Hz frequency tones in the better ear) which occurs before the onset of speech development and is not associated with visible external ear abnormalities or any other medical problems. It is usually nonprogressive and impedes oral language acquisition.

Also known as: prelingual non-syndromic genetic hearing loss, isolated prelingual genetic deafness, prelingual non-syndromic genetic deafness
