Abstract
An antimicrobial tympanostomy tube used to alleviate bacteriostatic infections following myringotomy which is compatible with otologic tissue associated with the middle ear. The tube is formed from a microporous thermoplastic or thermoset resin having incorporated therein 0.5 to about 15% by weight of a silver compound capable of migrating to the surface of tube sidewalls to impart a therapeutically effective level of antibacterial activity throughout the sidewall surface so as to provide long-term prevention of infections which may otherwise result during or after surgery or implantation of the tube.
