Visualization devices and methods for otologic procedures

[0028] Described herein are systems, devices, and methods for visualizing within an ear of a subject during an otological procedure. In some embodiments, the systems, devices and methods described herein can be used to provide visualization within the ear before, during or after pressure equalization or tympanic tube placement procedures.

[0029] Such as figure 1 As shown schematically in , an exemplary visualization system including a guide device 100 may be positioned in the ear canal EC of a subject and provide a view of a target treatment area, such as the eardrum TM. The guide device 100 may be configured to guide the instrument into the ear canal EC. In an embodiment, the guide device 100 may be shaped and function similarly to a speculum. The guide device 100 includes a body 110 that defines a channel or lumen 120 for receiving an instrument. The channel 120 may terminate in an opening 122 at the distal end of the body 110 within the ear canal EC. An instrument, such
