Intratympanic therapies for sensorineural hearing loss and vertigo

The theory behind intratympanic therapy is that by instilling small amounts (0.5 cc) of medications into the middle ear, absorption into the inner ear occurs though the round window. The medicines exert their effects on the cochlear and vestibular end organs. The benefits of these therapies include: control of systemic side effects, and the ability to treat the patients in the clinic or outpatient setting with encouraging results. The purpose of this paper is to explain the potential role of intratympanic therapy in treating specific inner ear disorders.
