    Abstract:
    Brainstem evoked response audiometry (BERA) is the most established and recommended objective audiometric method for the clinical diagnosis of hearing impairment in high-risk infants. It is unclear whether infants with orofacial clefts meet the criteria for the high-risk group. This retrospective cohort study evaluated the need for diagnostic BERA in infants with cleft palate with or without cleft lip by assessing the predisposition to and diagnosis of congenital hearing impairment. Data from 122 patients treated at a single cleft centre were evaluated. BERA was conducted at the time of palate repair at 4-6 months of age. Clinical follow-up was analysed up to 4 years. The presence of a syndrome was examined as a risk factor for congenital hearing impairment. Among the 122 patients, four had congenital sensorineural or mixed hearing loss requiring hearing aids. All affected patients had syndromes in addition to the cleft. Most patients with elevated hearing thresholds had transient conductive hearing loss. Most suspected sensorineural hearing loss initially diagnosed was refuted. However, a higher incidence of sensorineural hearing loss was found in patients with syndromic clefts, supporting the diagnostic use of BERA with initial surgery only in patients with syndromic clefts.
