The first case is a 57-year-old female who has been diabetic for 8 years and whose hearing of the right ear was 61.25 dB with a gradually sloping typed hearing loss.
This case was not cured. The second case is a 46-year-old female who has been diabetic for 2 years, and whose hearing of the right ear was 71.25 dB, with a flat typed hearing loss. The hearing loss recovered in the low frequency range. Sudden deafness in diabetics is uncommon but tends to be a bilateral and gradually sloping type. It is suggested that the patients with diabetes may require periodical hearing tests.
