We report cases of the dermoid cyst patients with a bone deformity that were treated with artificial dermis implantation. After resecting the tumor, three or five sheets of artificial dermis (Terudermis, Terumo Co. Ltd, Tokyo, Japan) are placed into the depressed site in order to create symmetrical surface with the contralateral side. Neither of the cases presented here showed allergic or infectious reaction during postoperative follow-up period. In both cases, the texture of the implanted region is almost the same as the contralateral side and is almost symmetrical. We believe that artificial dermis may be a useful implantation material to correct depressions in the patient with dermoid cysts.
