Pre-auricular skin tags are very common. Sometimes the tags are of skin only, but usually the tag contains a long tail of cartilage extending into the cheek.
It is commonplace to ligate pre-auricular skin tags soon after birth. A new technique is to apply a Liga clip. This is quick and easy to do, requiring no anaesthetic, and a few days later the tag drops off.
Tags with a substantial cartilage core are best treated by excision of the skin tag and cartilage spindle under general anaesthetic.
A bump on the helical rim is a common finding, often referred to as a Darwin’s tubercle. Clefts of the ear and ear lobe occur when two or more of the hillocks which form the ear during development fail to join together normally.
