It was down-sloping with loss ranging from 40 dB at 0.25 kHz, down to 60 dB at 8 kHz (Figure 1).

Pure tone audiometry still showed a moderate hearing loss:approximately 40 dB across all tested frequencies, a slight improvement in the higher frequencies when compared with the previous audiogram (Figure 2).
Audiogram following intratympanic steroid injection: o:right air conduction and [:right bone conduction, masked.

Air conduction was also within normal range except for an air-bone gap of 20 and 10 dB at the 0.25 and 1 kHz, respectively, secondary to the small perforation from the intratympanic steroid injection site (Figure 3).
