Ciprofloxacin/dexamethasone precipitate formation in the ear canal of a paediatric patient. This case report describes a paediatric patient diagnosed with otitis externa and treated with topical ciprofloxacin/dexamethasone. The patient completed the course of therapy and then developed precipitate formation from the pharmacological treatment. Laboratory testing of the precipitate confirmed the presence of a large quantity of ciprofloxacin. Removal of the precipitate required the use of an elephant ear washer system and removal with surgical tweezers. This case report investigated a probable topical ciprofloxacin/dexamethasone-induced ear precipitate formation in the ear canal, which, subsequently, was successfully removed from the patient's ear canal.
