Pure-tone audiometry revealed a left-sided moderate to profound mixed hearing loss (Figure 1). At her last follow-up visit, 12 months after surgery, audiometry showed improvement in both air and bone conduction thresholds, especially at frequencies between 250 and 1,000 Hz (Figure 1).

Axial CT scan and reformatted two-dimensional images obtained along the long axis of the petrous bone (Poschl plane) detected small foci of air density within the left vestibule and the basal turn of the cochlea (Figures 2 and 3).
