![]() ![]() The audiologist referred him to a pediatric otolaryngologist for further evaluation and necessary management. Therefore, the degree of hearing loss was unclear. In view of his age, behavioral audiometric testing was not appropriate. Otoacoustic emissions testing was performed of which no emissions were observed. The audiologist performed tympanometric testing which resulted in a bilateral type B tympanograms (no eardrum mobility) with intact eardrums. His parents reported a reflux of food and fluid into the nasal cavity after every feeding. He passed his newborn hearing screening prior to newborn discharge. His pediatrician initiated a referral to an otolaryngologist, geneticist and an ophthalmologist for vision testing as he will rely heavily on his vision due to his lack of hearing.Ī three month old male infant was seen for a routine audiological evaluation due to a complete cleft palate. His parents gave the audiologist permission to refer the infant to the DOH Early Intervention program and parent support group. His parents were very devastated but determined to move on and find out what they should do next to communicate with him. The test results concluded that he has a bilateral severe to profound sensorineural hearing loss. His parents reported no family history of hearing loss. A pediatric audiologist performed a series of audiological tests which consisted of a case history, middle ear evaluation, outer hair cell evaluation using OAE and ABR testing to estimate his hearing thresholds in each ear and to determine the type and degree of hearing loss. He was then referred to Children’s Medical Center for a comprehensive diagnostic evaluation. The hospital hearing screening program notified the Department of Health (DOH) Newborn Hearing Screening Program and the infant’s pediatrician. He came back for an outpatient rescreen two weeks later and an OAE screening was performed again. This current second edition chapter is a revision and update of the original author’s work.Ī three week old male infant, born at full term with no complications and with good prenatal care, did not pass a two stage hearing screening, OAE (otoacoustic emission) and ABR (auditory brainstem response), in either ear. ![]() ![]() The editors and current authors would like to thank and acknowledge the significant contribution of the previous author of this chapter from the 2004 first edition, Teresa Han Seo. ![]()
