A manually- or hydraulically-powered device designed to support a patient in a seated position to facilitate ear, nose, throat (i.e., ENT) examination, treatment, and/or minor surgery. It is typically adjustable in height to enable healthcare staff to perform procedures while standing. It usually includes head and armrests, a reclining back that may be tilted from a vertical to a horizontal position, and has rotating capabilities; some types can be programmed to standard positions. Devices intended for ENT examination and/or treatment (e.g., otoscopes, laryngoscopes) may be attached as components of the chair, or stand separately as self-supported, wall- or ceiling-mounted units.
