OBJECTIVE To explore the correlation between early clinical auditory brainstem response and long-term temporal bone development in patients with microtia and atresia. METHODS A retrospective review of clinical data of patients with MA,including ABR examination results in infancy,temporal bone CT results in adolescence and childhood,and basic demographic information. Comparison of ABR thresholds among patients with different temporal bone development statuses. RESULTS Jahrsdoerfer score and the degree of mastoid pneumatization were negatively correlated with ABR air conduction threshold and air-bone gap. The Jahrsdoerfer high score group of patients with congenital aural atresia had significantly lower ABR air conduction threshold(P=0.011) and ABR air-bone gap(P=0.033) than the low Jahrsdoerfer score group. The air conduction threshold(P=0.005) and air-bone gap(P<0.001) of ABR in mastoid process of pneumatic group were lower than those in non-pneumatic group in all patients with MA. The ABR air-conduction threshold(P=0.002) and ABR air-bone gap(P<0.001) in the congenital aural stenosis with cholesteatoma group were higher than those in the non-cholesteatoma group. CONCLUSION For patients with MA,ABR examination in infancy not only reflects the patients' hearing status but also has predictive value for temporal bone development.
