Abstract：Objective To study the relationship between hearing levels and temporal bone abnormalities in patients with congenital external and middle ear malformations. Methods Pure tone audiometry, auditory brainstem responses (ABR) and CT were conducted in 50 cases (60 ears). Hearing level and temporal bone abnormalities were examined and compared. Results The pure-tone average was 64.08±13.07 dB HL and the average A-B gap was 53.28±12.05 dB in pa-tients with conductive hearing loss. There was a positive correlation between hearing and Marx grading and a negative correlation between hearing and total CT scoring. Hearing was correlated with ossicular chain, middle ear development and facial nerve scorings, although it was inconclusive regarding the formation of oval/round windows. Conclusion Us-ing pure tone audiometry and ABRs, in addition to CT, we can clinically assess hearing status and external and middle ear development, thus guiding the clinician in approaching potentially difficult surgeries.
