Devices, systems, and methods can be employed to facilitate indirect viewing into cavities such as, but not limited to, the middle ear space. Some embodiments have uses such as, but not limited to, facilitating visualization and procedures in the outer, middle, and/or inner ear in order to diagnose and/or treat disorders including, but not limited to, hearing loss and other ear disorders. In particular implementations, a surgical microscope is used in conjunction with an inverter lens and a distal lens. In some cases, the distal lens transverses a membrane or septum such as, but not limited to, the tympanic membrane. The distal lens can be an assembly combining two or more lenses, in some embodiments. For example, in some cases wide angle lenses, zoom lenses, lenses of other various shapes and/or prisms can be used in the distal lens.

Visualization devices, systems, and methods for otology and other uses

Devices, systems, and methods can be employed to facilitate performing procedures in the outer, middle, and/or inner ear in order to diagnose and/or treat disorders including, but not limited to, hearing loss and other ear disorders. For example, this document describes devices, systems and methods that include instruments and techniques to minimize the invasiveness and/or to enhance the efficacy of procedures that are performed in the outer, middle, and/or inner ear spaces such as mastoidectomy, tympanoplasty, cholesteatoma treatments, otosclerosis treatments, and Eustachian tube treatments.

Devices, systems, and methods for otology

Systems and methods can be employed for facilitating access and procedures in the outer, middle, and inner ear in order to diagnose or treat ear disorders including, but not limited to hearing loss and excessive ear wax. In some examples, the systems and methods include instruments and techniques that facilitate trans-tympanic membrane or trans-fibrous ring access to the middle ear. The systems and methods can also be used to improve accessibility for various otological surgical procedures, such as, but not limited to, cholesteatoma removal, tympanic membrane repair and ossicular chain repair.

Systems and methods can be employed for trans-tympanic membrane access to the middle ear for delivery of a formulation or implant device to a target location 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.

Devices, systems, and methods for treating ear disorders

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.
