Abstract

|
The formation or reconstruction of an auricle is one of the most difficult operations in plastic and reconstructive facial surgery.
The difficulties of its reconstruction include delicate structures of the ear, extremely thin skin, difficulty in color match, and springing effect of the thin supporting skeleton consists of cartilage with its peculiar recesses and bumps.
Even though, several techniques have been using for auricular reconstruction, it would be difficult to obtain an ideal auricle. Furthermore surgeon´s talent and sufficient practice might be needed for a satisfactory result.
We attempted auricular reconstruction using negative auricular plastic mold in 10 white rabbits in order to pursue a simple and satisfactory method. Diced cartilage chips were filled into a subcutaneous pocket placed in the negative auricular mold. Mild negative pressure was maintained in the space between the cartilage-subcutaneous tissue-skin complex and mold for two months.
The results were as follows
1. An ideal shaped suitable supporting skeleton was newly formed and the fabricated new auricle had a near normal appearance.
