A tympanostomy tube is provided for insertion into and residence in a tympanic membrane of a mammal. The tympanostomy tube has a body including a first end portion, a second end portion and a central portion disposed between the first and second end portions. Additionally, an axially extending passageway is provided having a first open end and a second open end. The first end portion includes a relatively enlarged diameter radially extending flange disposed adjacent a first end of the first end portion, and a relatively reduced diameter portion. The second end portion includes at least first and second moveable legs having first ends coupled to the first end portion and second ends. The second ends include sharpened surfaces that are sufficiently sharpened to incise through the tympanic membrane during insertion of the tympanostomy tube in the tympanic membrane.
