Проведение косметической отопластики с учетом биомеханики кожи

Abstract

Protruding pinna commonly encountered congenital deformity, which is characterized by an excessive deviation of the ear from the surface of the head and in most cases this is due to underdevelopment antihelix. Purpose of the study. Improved techniques of cosmetic otoplasty considering stretching the parameters of relaxation and skin-fat flaps. Materials and methods. The study involved 15 patients with droopy ears, their cosmetic otoplasty considering biomechanical and morphological studies were carried out. For the isotonic experiments were selected for the physical parameters of skin flaps, which are responsible operations – cosmetic otoplasty. Patches have a rectangular shape. The skin is freed of subcutaneous fat with scissors. The dimensions of the flap had dimensions: length 8 mm, width 10 mm, thickness 0.9 mm. The materials for the study were histotopography skin-fat flaps mastoid areas that were excised during cosmetic otoplasty. To achieve the goal of tissue were stained by the methods van Gison and hematoxylin-eosin. Given these biomechanical research carried out, the formation of the corner and the border tension skin-fat flaps have acquired the following values: in the upper and lower parts of the cartilage formed at an angle of 6-7 °, in the central - 19-20 °. Thus, on the basis of conducted biomechanical and morphological studies we have been proved optimal method of cosmetic otoplasty that provides surgery with preservation of the natural tissue topografoanatomicheskih relations.
