The term cauliflower ear refers to a deformity of the ear caused by blunt trauma or other injury, such as what may occur during a boxing or wrestling match. Left untreated, the injury leads to a blockage that prevents blood flow and damages tissue. This results in a bumpy or lumpy appearance on part of the ear, similar to a cauliflower. Early treatment can help prevent permanent deformity. Fortunately, the types of injuries that cause cauliflower ear are often preventable by wearing the right type of protective head gear.

Causes of Cauliflower Ear The most common cause of cauliflower ear is a hit to the ear -- or repeated hits to the ear -- that leads to hematomas, or small collections of blood that clot and block the flow of blood and nutrients. These can also occur when skin is pulled away from cartilage, the semi-rigid tissue that gives the ear its shape. Usually, cauliflower ear is related to sports injuries, but not always. Any trauma to the ear can cause it. Cauliflower ear can even be the result of an infection in the ear lobe. When blood flow is blocked, the affected cartilage may die and, without the supportive tissue, fold in on itself. Scar tissue may form, contributing to a swollen and deformed look. Over time, the effects may become more prominent, and they may be permanent. The good news is that cauliflower ear can usually be prevented, even after such an injury occurs.
