Video otoscopy is an advanced method to see the ear canal and eardrum in order to diagnose common ear diseases. It provides high quality images of the ear canal and eardrum, which enables the audiologist to identify any abnormalities, such as redness, swelling, discharges or wax build up. Wax is a normal function of the ear canal as it is a way to protect the ear from foreign objects. The advantages of video otoscopy, compared to analogue otoscopy, is that the images of the outer ear can be captured and stored for record keeping and reporting purposes. It also gives a higher quality image than most analogue otoscopes.
