Q

A 20 year old student gets punched in the ear whilst on a night out, their is significant brusing and swelling of his ear, what is the risk and pathophysiology?

The perichondrium may have been sheared from the tightly adhered cartilage forming a haematoma between them.

If the haematoma is not drained there may be avascular necrosis of the cartilage. This will lead to new cartilage growth and a deformed ear aka cauliflower ear.
