Hypothesis: Molecular genetic testing should be part of the initial evaluation of
children with sensorineural hearing loss (SNHL).
BACKGROUND
Hearing impairment is the most common sensory deficit in children, and
SNHL is the most common form of congenital hearing impairment. It is also
a significant health care problem. More than 40 000 children are born
in the United States with significant hearing impairment, including about
4000 who are profoundly deaf. The incidence is estimated at about 1 in every
1000 live births.1 Therefore, the otolaryngologist
will frequently be challenged to determine the appropriate diagnostic regimen
for this subset of children, a difficult and controversial procedure.

It is well accepted that a careful history, physical examination, and
audiological evaluation are the first and most crucial tools used to diagnose
the cause of hearing loss.1-4
Many syndromes associated with SNHL can be diagnosed with these 3 methods.
