A video otoscope includes an elongated body portion having a conically shaped insertion portion sized for insertion a predetermined distance into an ear canal. The insertion portion includes a tip opening and an interior having a lens system for focusing an optical image of a target onto a distally positioned imager each contained therein. The body portion includes an insufflation port to pressurize or apply a vacuum within the ear canal to allow stimulation of the tympanic membrane. In a preferred embodiment, a clear speculum releasably attached to the insertion portion transmits light to a target within the ear canal, while also allowing insufflated air to be reliably guided to the tip opening.
