PROCEDURE

The sculpture was indirect, the ears of the patient’s brother being used as a guide.2 Impressions of the ears were made with alginate (irreversible hydrocolloid) impression material. The molds thus obtained were applied as well as possible to the lesions in a model of the head of the patient. Holes were made in the posterior parts of the alginate impressions, and melted wax was poured into the impression through these holes. Rectangular “extensions,” directed upward, were added to the wax models thus obtained. Acrylic resin with an intrinsic pigmentation obtained with mineral powders was used for the prosthesis. In the finished prosthesis, the extensions were attached to the thick temple pieces of glasses by means of self-curing acrylic resin. A slight support in the -Translated *Assistant
