Bleeding into the ear
This lump is most probably a benign cyst which may need proper drainage. Our outer ear is made up of cartilage. Cartilage does not contain blood vessels. It takes nutrition from the thin outer membrane called the perichondrium. As the lump contains blood in between the cartilage and the perichondrium, there is a risk of cartilage being deprived of nutrition resulting in cartilage damage resulting in cauliflower ear. This may lead to a deformed ear. The blood that has collected should be removed immediately. The skin of the ear is anaesthetised and the crescent-shaped piece is removed. When the blood is drained, the perichondrium will again settle tightly upon the cartilage and restore the nutritional requirement. This cut should be dressed and kept firmly bandaged for about five days. Antibiotics and painkillers are given during this period. If the bandage is too tight, doctor should be informed. When the bandage is removed after five days, the ear has healed. Sometimes, the wound may need dressing for between two and three days. If the lump is punctured with an unsterilized needle to remove the blood, the cartilage may become infected leading to death of cartilage resulting in an abnormal shaped ear which is called a cauliflower ear.
