신생아 난청 선별검사에서 일측성 재검으로 의뢰된 환아의 단기 경과 관찰 결과

Abstract

Background and Objectives Hearing screening is mandatory for newborns. The management of patients who fail hearing screening is important. This study examined the prognosis of patients who had hearing loss detected on the newborn hearing screening. Subjects and Method The results of newborn hearing tests, follow-up hearing tests, and risk factors for hearing loss were analyzed retrospectively in prospectively collected data. Newborn hearing screening testing using an auto auditory brain stem (ABR) response was perfor-med for 1296 newborns from January 2010 to December 2012 at Soonchunhyang University Bucheon Hospital. Follow-up hearing tests using ABR and otoacoustic emissions were perfor-med 6 and 12 months after the newborn hearing screening. Results Of the 1296 newborns who underwent hearing screening tests, 63 were referred and 58 had confirmed hearing loss. The hearing loss was unilateral in 74.2% (43/58). During the 1- year follow-up, about half of the patients showed improved hearing function. Premature birth was related to hearing recovery. Conclusion During the follow-up, some patients with unilateral hearing loss showed recovery. Some premature patients can expect hearing recovery during follow-up testing. Regular follow-up after newborn hearing screening is important to detect hearing changes in this period.
