    Abstract:
    Patients with cleft lip and/or palate abnormalities are likely to suffer permanent conductive (PCHL) or sensorineural hearing loss (SNHL) due in part to the association with syndromes known to include PCHL or SNHL. The presence of otitis media, a nearly universal complication in these patients, makes identifying the hearing impaired in this population a challenge, since the detection of permanent hearing loss is made more difficult. This problem might be overcome by using click-evoked otoacoustic emissions (CEOAE's) shortly after birth. Twenty-one out of 28 newborns presented to the regional cleft palate team were eligible for CEOAE screening shortly after birth. Among these 21 infants, five had anomalies other than cleft lip and/or palate associated with an increased risk for hearing impairment. At the first CEOAE screening (ILO88 Emission Analyser, mean age 3 weeks, range 1-11 weeks) clear CEOAE's were present in all of the 18 ears of nine infants with isolated lip and/or jaw clefts. In 24 ears of 12 infants with palatal clefts, CEOAE's were present in only six ears (three infants), not demonstrable due to noisy registration in another six ears and absent in 12 ears despite a quiet registration. During follow-up of those who failed the first screening (18 ears, nine infants), normal hearing was found in 14 ears (seven infants) and sensorineural hearing loss was documented in four ears (two infants). CEOAE screening in infants with isolated lip and/or jaw clefts seems feasible and effective. In infants with palatal clefts an auditory brain stem screening might be more appropriate.
