🌿 Overview
Cauliflower ear is a deformity of the outer ear that follows a blunt blow or repeated friction, common in wrestling and contact sports. The injury causes blood to pool between the ear's skin and its cartilage; if it isn't drained promptly, the cartilage scars and the ear takes on a lumpy, folded look. Quick cold treatment and early medical drainage prevent the permanent change.
The outer ear is a thin layer of skin over flexible cartilage that gets its blood supply through that skin. A hard knock can tear small vessels so blood collects in between (an auricular hematoma), cutting the cartilage off from its nourishment. Left alone, the trapped blood hardens and the cartilage shrivels and scars into the characteristic 'cauliflower' shape.
Immediately after a blow, cold compresses and gentle pressure help limit swelling, but a hematoma that forms needs to be drained by a clinician within a day or two to prevent deformity — home remedies cannot drain it. Protective headgear prevents the injury in the first place. Watch any ear injury for signs of infection.

- A soft, tense lump on the ear (collected blood)
- Redness and warmth
