The auricular pavilion constitutes an important part of the hearing sense, so much from the functional point of view as of the aesthetic. Located behind of the temporomandibular joint covers the previous part of the mastoid. The auricular pavilion is one of the most visible appendices of the face and any injury results quite apparent, producing large complex to the patient.
CLINICAL CASE: We present the case of a of 53 years old man that suffered an traffic accident, with facial, truncal and extremities superior injuries. As consequence of the trauma had tear off the right auricular pavilion. The injuries were reconstructed through local flaps and the new auricular pavilion was made through technical of Brent.
Inicially, we make a just oblique incision on the costal margin. Once the muscle has been divided, we used the standard film to determine what cartilages will serve better for the structure. They are obtained in block from the opposite side to the ear that is going to be reconstructed to be used of the costal natural configuration. The free zone graft is used to give form to the helix. The synchondral region of the six and seven rib provide a wide cartilage block for adapting the body of the auricular structure. fig.1, fig.2
Later, a skin pocket is created to provide an adequate vascular container that covers the structure. Using the insole and through the preoperative measurements, is brand the position of the ear and is accomplished a small incision preauricular, with care of preserving the vascular plexus.fig.3, fig.4
The auricular reconstruction, so much of traumatic, oncologic or malformative pathology it can be accomplished through different surgical procedures, between them the use of autogenous cartilage of the opposite ear, allografts of motherly cartilage or of corpse, xenografts or inorganic material implants. The autograf of costal cartilage was employed first by Tanzer, and thereinafter Brent, Spina and Carroll developed and modified the technique.
Two months later, the patient was submitted to release of the costochondral graft and reconstruction of the ear.The auricular removing began with a peripheral incision to several milimetres of the posterosuperior margin, being careful of preserving the conective tejido under the cartilaginous surface.
The skin graft covered the subsequent face of the new pavilion and the external face of the mastoid region. The auricular lobe was transposed in a third time, to give greater depth to the conchal region.fig.5,fig.6,fig.7
