[Value of tissue expansion in total reconstruction of the external ear]

By recalling the imperatives of auricular reconstruction, the author analyses the indications for tissue expansion in this area. This expansion can be performed preoperatively or intraoperatively, directly on the ear, indirectly, away from the ear. In the light of his experience, illustrated by three clinical cases, the author considers preoperative indirect expansion to be the most useful, by placing the expander underneath the scalp.
