"The liner closure is useful to coverage of round skin defects caused by various etiologies as long as the location and the size of the defects are allowed. If it is impossibel, the round skin defects should be covered by using skin graft or local flaps. The methods of local flap are variable according to the design ofr covered of rund skin defect. The slide-swing plasty used one side of skin flap and doubel Z-rhomboid plasty used both side flaps are the most effective and represntative method among the several local flaps.
  During the past 10 yeasr, aoutors have  een treated with round skin defect in 10 cases of double Z-rhomboid plasty and 7 cases of slide sweing plasty among the seeral local flaps. We compared the suefulness, advatnages, and disadvantages fo each technique.
 The doubel z-rhomboid plasty is versatile and elegant method of closure that sahres the coverage of a defect with two adjacent flaps. It is can result in leaving the smalest scar and yilds superior comsmetic results without displacing anatomical landmarks, designing the long axis of rhombus and relaxsed skin tension line in accordance, so main suture line is parellel to the RSTL by minimizing clousre tesnion. But anatomic landmark is placed on the surrounding tissue, the design is difficulty.
 The slide swing plasty is a combination of transposition flap and skin sliding, in which the flap employed to close the defect and the defect itsefl are cutto a round shape. Its advantage consists in the possibility of closing large defect without skin graft, regional anatomic peculiarities, good vasculized flap, and avoidance of secondary defects.
