There does appear to be a remnant of the malleus, with is anteriorly and superior displaced. No definite erosion is identified in the region of the tegmen tympani but it appears slightly thinner and more bowed out. The scutum is at least partially absent. The ossicular erosion has progressed since the prior exam (correlate with surgical procedure). Again, the basal and first turns of the cochlea are seen, but the apical turns are not well visualized indicating incomplete formation.
