Iatrogenic trichloroacetic acid injury causing necrotizing otitis media and deafness

Trichloroacetic acid (TCA; also known as trichloroethanoic acid) is a corrosive agent that can produce significant burns when applied topically to the skin or mucosal membranes [1]. This property underlies its use in numerous dermatologic and gynecologic procedures including wart removal, chemical dermabrasion, and ablation of pre-cancerous and cancerous lesions of the skin and genitals [2 –4]. In otology, TCA is used topically to help small tympanic membrane (TM) perforations to heal and to calm granular myringitis; it may also be useful in the treatment of acute external otitis [5,6].
