ABSTRACT
The external ear is commonly involved in facial trauma. Injuries to the ear can range
from simple lacerations to complete avulsions. We review the normal auricular anatomy
and vascular supply, as well as the initial management of any auricular injury. Furthermore,
we review the literature on soft tissue injuries of the ear and present a simple algorithm
for classifying injuries. The classification is based on whether or not cartilage
is involved. Injuries to the lobule do not involve cartilage and thus are more easily
repaired by simple closure or Z-plasty. Injuries involving cartilage are further classified
into partial or complete avulsions. A complete avulsion is then categorized by having
a wide or narrow pedicle. There is no standardized, definitive management for the
various types of auricular trauma, and this schema may assist in deciding which of
the various reconstructive options is most appropriate for a particular case.
