In general social opinions of developed cultural state, tattoos induced psychological and social problems. Since Hellenic times, the removal of unwanted tattoos has been a challenge: for example, salabrasion, dermabrasion, LASER surgery, skin graft and cryosugery, etc. But the availability of manay methods for the removal of tattoos appears to indicate that there is no one absolute method. So we studied macroscopical color changes and microscopical histological changes in tattooed rabbits and rats, and overtattooed rabbits and rats. The results were as following: 1. Inflammatory reactions was nearly almost disapperared within 3 weeks. 2. The major fade―out of tattooed color was occurred from post―tattooing 5 days to 3 weeks. 3. Dye particle was located mainly in upper & mid dermis and it was not relafted with tattooing depth. 4. Masking effect of black colored tattoos was definitely improved in the overtattooing group. But complete masking was impossible.

Congenital earlobe defects fall into two categories : a simple cleft due to developmental malunion or a hypoplastic cleft with significant deficiency of the soft tissues. The location and size of congenital defects vary depending on embryology. The degree of defects vary from slight indentation of periphery to complete division of lobule including the cartilagenous skeleton. Traumatic defects that result from ear piercing are the most commonly acquired defects of the earlobe. For the methods of repair, accurate evaluation of the deformity with regard to the depth and width of the cleft and tissue deficiency must be carried out. Orientals have thought that the earlobes are significant cosmetic or physiognomic symbols so we reconstructed the earlobes considering all its aspects. We experiedced five cases of earlobe defects and managed them by Z-plasty, double Z-plasty, dermofat graft and composite graft methods. The resultts are as follows; 1. If there is enough local tissue for repair, Z-plasty and double Z-plasty methods are good enough to correct the ear lobe defect. 2. If the residual earlobe is hypopastic with significant deficiency of the soft tissues, composite graft and dermofat graft methods are requred for reconstruction.
