case_images: Physical examination and audiometric findings of the ear. A, B) At the initial visit, the skin of both (A: right ear, B: left ear) external auditory canals was edematous with pale polyps and otorrhea. The tympanic membranes were invisible. C, D) After the treatment, the edema and polyps disappeared from the skin of both (C: right ear, D: left ear) external auditory canals, and otorrhea also stopped.

case_images: She was referred to our hospital after the tympanic membranes had been perforated in both ears and when granulomatous masses developed in both external auditory canals (Figure 1A and B).  On hospital day 38, otorrhea stopped in both ears (Figure 1C and D), and air conduction hearing also improved (Figure 2B).
case_images: Audiometric findings. A) At the initial visit, pure-tone audiometry revealed bilateral mixed conductive-sensorineural hearing loss with 63.8 dB in the right ear and 47.5 dB in the left ear. B) After the treatment, air conduction hearing improved in both ears.

case_images: Pure-tone audiometry revealed bilateral mixed conductive-sensorineural hearing loss of 63.8 dB in the right ear and 47.5 dB in the left ear (Figure 2 A). On hospital day 38, otorrhea stopped in both ears (Figure 1C and D), and air conduction hearing also improved (Figure 2B).
case_images: Computed tomography findings. A, B) At the initial visit, the tympanum and mastoid air cells were filled with soft tissue attenuation in both (A: right, B: left) ears. No apparent bone destruction was observed. C, D) After the treatment, air was observed in the tympanum and mastoid air cells of both (C: right, D: left) ears.

case_images: Computed tomography (CT) revealed that the tympanum and mastoid air cells were filled with soft tissue attenuation in both ears (Figure 3A and B). Since CT revealed air in the tympanum and mastoid air cells of both ears (Figure 3C and D), the antibiotic therapy was changed to the oral administration of CAM 800 mg and STFX 100 mg on hospital day 41.
