Ear examination. Doctor using an otoscope to examine a boy's ear. The otoscope provides a magnified view of the ear canal and eardrum. Children are more susceptible to ear infections than adults, as their eustachian tubes, which link the ear to the nasal cavity, are shorter. This means infections of the nasal cavity can easily spread to the ear.
