Abstract

Systems and methods can be employed for trans-tympanic membrane access to the middle ear for delivery of a therapeutic agent, for example, to the round window niche adjacent to the cochlea under direct visualization. The systems and methods can also be used to improve accessibility and visualization for various otological surgical procedures, such as, but not limited to, cholesteatoma removal, tympanic membrane repair and ossicular chain repair.
