case_images: Audiometry showed mild mixed hearing loss with a 5-10 dB gap at low frequencies and 30 dB SRT to the left, and moderate to severe mixed loss with a 20-35 dB gap and 80 dB SRT to the right (Fig. 1A); the speech recognition index and tympanometry were within normal limits, and the stapedian reflexes were absent. Vertigo diminished partially and hearing improved after treatment with an antivertiginous drug and corticosteroids (Fig. 1B). Computed tomography of the temporal bones revealed apparently well located soft tissue density material in the oval window and around the prosthesis (Fig. 1D). Audiometry showed profound sensorineural hearing loss to the right, with 95 dB SRT (Fig. 1C).
