The insertion of ventilation tubes to equalize pressure in the middle ear is the most common procedure used to treat otitis media. This article evaluates the advantages and drawbacks of ventilation and explores the various roles of the components of middle ear pressure, with special emphasis on oxygen-derived free radicals.

D005609	Free Radicals	Highly reactive molecules with an unsatisfied electron valence pair. Free radicals are produced in both normal and pathological processes. Free radicals include reactive oxygen and nitrogen species (RONS). They are proven or suspected agents of tissue damage in a wide variety of circumstances including radiation, damage from environment chemicals, and aging. Natural and pharmacological prevention of free radical damage is being actively investigated.	Free Radical
