HISTOLOGIC STUDIES ON THE FATE OF DEEPLY IMPLANTED DERMAL GRAFTS

Abstract

This series of experiments was conducted to determine the advisability of filling a depression by burying a free section of dermis and fat underneath the skin. Eitner¹ in 1920 described a method of elevating a depression of the face by inserting a free section of deepithelized derma beneath the skin overlying the depression. He reported a case of paraffinoma of the cheek in which a depression resulted from the removal of the paraffinoma. Eitner removed the epidermis from a hairless portion of the abdomen with a Thiersch knife and excised a section of dermis and underlying fat. This he transplanted under the skin of the cheek. He observed the patient for about eight months and reported a completely satisfactory result. He apparently removed the epidermis for the purpose of insuring sterility of his transplant, but in this article he did not mention the possibility of the formation of a
