This examination involves using an instrument called an otoscope to look inside the ear. An otoscope transmits a bright light into the ear canal and has a tiny video camera which relays images to a TV screen. It also has a working channel that can remove debris within the ear by flushing or drying it out.
A video ocoscope allows the hearing specialist to better examine the ear than a hand held ocoscope. The instrument is especially effective for deep ear flushing, flushing behind a ruptured ear drum, and detecting and biopsying tumors in the ear canal.
