Case description

There is a medium sized healed perforation in this right tympanic membrane. One can see easily into the middle ear because this perforation healed without a fibrous middle layer. A normal tympanic membrane has three layers: an outer epithelial layer, a thick fibrous middle layer, and a thin mucosal inner layer. It is the thick fibrous middle layer that gives the tympanic membrane its strength.
