A device and method for treating maladies, particularly of the external ear canal and eardrum, is disclosed. In a preferred embodiment the device comprises an earplug or plug and a delivery bulb that holds treatment fluid. A lumen extends through the earplug and connects the delivery bulb to an orifice located at the distal end of the earplug. A one-way valve is located along the lumen to allow treatment fluid to only flow from the delivery bulb to the orifice and not vice versa. The earplug forms a seal with the patient's external ear canal and, combined with the one-way valve, retains treatment fluid in the patient's external ear canal where it can perform its therapeutic function. In one embodiment, the invention includes a collection bag connected through the earplug to an orifice near the distal end of the earplug to collected waste treatment fluid. The therapeutic method comprises using a device, as disclosed herein, to deliver treatment fluids to the patient's external ear canal for irrigation, for the therapeutic benefit of the treatment fluids for the short and long term or to deliver treatment fluid to a patient's external ear canal where it can pass into the patient's middle ear through a tympanostomy tube placed in the patient's eardrum.
