"The presence of epicanthal folds in Asian eyelids is one of their unique features, in combination with the lack of supratarsal folds. Western culture has influenced many people to prefer to eliminate the prominent epicanthal fold.
 A number of surgical techniques have been suggested for their correction. However, difficulty with design, excessive and prominent Scarring of medial canthal and nasal area, recurrence, and rigidity of application are potential problems associated with many procedures.
 This paper describes a epicanthoplasty with three-dimensional Z-plasty. Through epicanthal fold incision, the medial canthal tendon is medially advanced and sutured to the periosteum of nasal bone. After the transposition of the flaps, trimming of the flap is usually required. Three-dimensional Z-plasty creates the attractive eyes.
 From March, 1995 to March, 1997, the technique was applied to 37 patients with epicanthal fold and was performed with or without double-fold operation. There were 34 females and 3 males with ages ranging form 17 to 30 years. Through 2 years follow-up, this technique has delivered esthetically good results with minimal postoperative scar and could made the reduction of ICD form 40± 2,13mm to 34±1.98mm.
 The advantages of epicanthoplasty procedure using three-dimensional Z-plasty(Yoon's method) are as follows; 1) simple in design 2) minimal postoperative scar in the medial canthal area 3) versatile in its application 4) no recurrence 5) no hypertrophic scar 6) preserving ethnic identity.
