[Management of severe ear aplasias]

Microtia set two problems. A functional one in the case of bilateral microtia. The middle ear surgery has bad result specially in the cases of oto-mandibular or Treacher-Collins syndromes. In the unilateral microtia the results are slightly better, so the functional surgery is effected after a radiographic evaluation. The esthetic problem proper is now corrected with the B. Brent technique.
