Dr. Michelle Pho and Elizabeth Mandell from the Audiology Department at Dell Childrens Medical Center spoke on Hearing loss in a pediatric population and the importance of early detection and intervention.
They reported that 14.9% of new born have a mild hearing loss in one ear . Universal newborn hearing testing is so important because it is difficult to detect and it can delay or impair speech and language development. Hearing loss can lead to social and emotional problems and underachievement and academic failure. Early detection should ideally be done before six months of age. Dell is the outpatient follow up if the newborn fails. They will follow from birth to 18 yrs. Dell does behavioral audiometry, Supplemental physiological testing, physiological audiometry, and auditory brain stem response. ABR testing is done during sleep or anesthesia to detect brain stem response. Last year, 345 ABR tests were done 209 were normal, one quarter were detected as a bi lateral or unilateral loss so 23% were a first time detection. A pending purchase is for a Interaccustics Titan that will allow them to better detect temporary loss. Sertoma has helped them by getting good equipment.
