title: The Peng flap. The flap of choice for the convex curve of the central nasal tip.
abstract: BACKGROUND
  Surgical defects of the convex curve of the central nasal tip have always been difficult to repair. Most dermatologic surgeons use a full-thickness graft in this region. The pinch modification of the linear advancement flap was described by Peng et al in 1987 as a means of repairing this region.
  
  
  OBJECTIVE
  This purpose of this paper is to discuss the effectiveness of using the Peng flap for repairs of the convex curve of the central nasal tip.
  
  
  METHODS
  This flap was used on a series of 25 patients, all of whom had defects of the convex curve of the central nasal tip.
  
  
  RESULTS
  Because the flap both rotates and advances, it shortens the length of the traditional advancement flap and increases flap survival rate. We found excellent cosmetic results for central nasal tip defects and had no complications of necrosis using this flap.
  
  
  CONCLUSIONS
  We have found this to be an excellent flap for repairs of the convex curve of the central nasal tip, as the rotating arms of the flap conform to the three-dimensional shape and the lateral lines fit well into cosmetic lines of the nose. When repairing central nasal tip defects, we believe the Peng flap to be the flap of choice to re-create the convex curve of this region.
