Lyric hearing aid: a rare cause of benign necrotising otitis externa/external ear canal cholesteatoma.

An 80-year-old Caucasian man presented with an incidental and asymptomatic lesion in his right ear thought to be secondary to his use of hearing aids for presbycusis. He used Lyric hearing aids, designed for 24 hours-a-day use for 4 months at a time and had no other previous otological problems. He underwent a bony meatoplasty and vascular flap reconstruction via a retroauricular approach to remove the lesion for histological analysis and regrafting of the area. The lesion was confirmed on histopathology as an ear canal cholesteatoma.
