ENT · Audiology: infant screening follow-up
Sample itemA newborn fails two otoacoustic emission screens. Which is the next investigation?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Brainstem evoked response audiometry
A baby who fails OAE screening needs objective electrophysiological confirmation with ABR (BERA), which also detects neural lesions such as auditory neuropathy. Behavioural tests like pure tone audiometry are impossible at this age. Early identification allows intervention by six months.
Option by option
A. Tuning fork tests
Tuning forks are unreliable and not feasible in neonates.
B. Caloric testing
Caloric testing assesses vestibular function, not hearing.
C. Pure tone audiometry
Pure tone audiometry needs voluntary responses, so it is not possible in newborns.
D. Brainstem evoked response audiometry (correct)
Correct. BERA is the objective confirmatory test in infants.
