Otoplasty

Otoplasty - surgical restoration of the ear at the partial or complete absence due to frostbite, gunshot wound, burn, or interrupting her.
To resolve partial defects using local fabrics parotid region and transplants, transferred to defect from other areas, using stalked or spiral flap. Cm. also Plastic surgery.

Otoplasty (from Greek. ous, otos - ear and plastike - shape) - restore or fix surgically deformities of the ear and ear canal. Applies when you damage the ears, after frostbite, in congenital deformities of the ear or in the complete absence of it. Otoplasty is one of the most difficult sections of plastic surgery. The difficulties these operations include choosing transplant technique of formation of complex patterns of shell, the restoration of the ear canal.
For minor defects in shape of the ear (the presence of prioskol, change the lobes and so on) can be limited to a simple and easy operations. When restoring curls ear or lost of the sink, when atresia require more complex intervention. In such cases, the grafts taken near from defect with the neck, behind the ears, or at the private parts of the body with the subsequent transfer to the proper place. Mobilization of the skin in the place of the missing sinks, as a rule, does not provide sufficient material for plastics; therefore it is expedient to take the skin near the sink and in such quantity that it was enough for the formation of a shell.
With this purpose prepare stalked graft (Fig. 1) - Filatov or spiral stem, S. A. Proskuryakov (Fig. 2). The latter is more suitable for formation of a curl or full recovery of the ear. Often when otoplasty have to resort to the support transplants, which use cadaver cartilage by N. M. Mikhelson or autograft in the form cartilage milling shavings by S. A. Proskuryakov. For the same purpose use and alloplastic material (strings, thin pins and so on).
When atresia ear canal apply methods Routine, Neumann, B. S. Preobrazhenskaya, K. L. Chilova, S. A. Proskuryakova (Fig. 3-6). Cm. also Plastic surgery.
