[External ear traumas and their complications].

The external ear is often involved in facial trauma. This is an updated review of the major conditions involved in external ear traumas: the auricular haematoma, the auricular perichondritis and the auricular laceration. These conditions must be quickly diagnosed and treated due to a risk of a severely deformed ear if left untreated. This is also a brief summary of the possibilities in reconstructive surgery of the ear. There is no high-quality level of evidence regarding the management for the various types of auricular trauma, which is why, further research is needed in this field.
