Otoscopic Examination

Reference work entry


Prior to conducting hearing evaluations, patients’ ear canals and tympanic membranes (ear drums) are visually inspected with an otoscope (a hand-held device with a high-powered light source that is focused into the ear canal which is illuminated through an appropriately sized speculum) to examine for the presence of cerumen (ear wax), foreign bodies, physical abnormalities of the structures, infections, tumors, ear drum perforations, or other conditions that could interrupt the transmission of sound or present health concerns. Otoscopic examination is an important part of hearing aid fittings and routine follow ups.
