Using graphic animation, this video shows the step by step process for removing tonsils and adenoids, including these anatomical structures that are located in the throat.

This animation not only shows how the ear detects sound waves and converts those waves into nerve signals, but it also shows how cochlear implants work and allow patients with nerve deafness to hear.

It is not uncommon for fluid to accumulate behind the eardrum (tympanic membrane). In this animation, we see the surgery used to open the tympanic membrane (myringotomy) and the placement of a drainage tube. This procedure is known colloquially as a patient "getting tubes in his ears."

People hear sound waves when the ear and associated structures convert sound energy into nerve impulses. An overview of the way in which the ear "hears" is discussed along with discussion of the two main types of hearing loss: conductive hearing loss and sensorineural hearing loss.
