AB  - OBJECTIVES/HYPOTHESIS: We aim to define the frequencies of anomalies of the inner
      ear, oval window, and round window ipsilateral to isolated non-syndromic
      unilateral aural atresia. METHODS AND MATERIALS: Retrospective case series. We
      reviewed high resolution computed tomography scans of the temporal bones of 70
      children with isolated non-syndromic unilateral congenital aural atresia. Scans
      were reviewed according to the Jahrsdoerfer criteria and further evaluated for
      anomalies of the vestibule, semi-circular canals, cochlea, internal auditory
      canal and vestibulocochlear nerve. RESULTS: Inner ear dysplasia was seen in two
      of 70 atretic ears: one with a dysmorphic lateral semicircular canal and another 
      with a large vestibule assimilating the lateral semicircular canal. Abnormalities
      of the oval window and round window ipsilateral to the atresia were identified in
      21% (15) and 7% (5), respectively, of the atretic ears. Oval window and round
      window abnormalities were associated with disproportionately lower Jahrsdoerfer
      scores compared to aural atresia patients without these abnormalities (P < 0.001 
      and P = 0.04, respectively). CONCLUSION: Compared to studies that included
      syndromic or bilateral atresia cases, we found inner ear and oval window
      abnormalities less common in children with isolated non-syndromic unilateral
      aural atresia. However, round window anomalies seem to occur at about the same
      frequency.
