title: [Clinical application of a retrograde nasolabial fold island flap based on the upper lip artery].
abstract: OBJECTIVE
  To explore a new method for enlarging the rotation range of the nasolabial fold flap.
  
  
  METHODS
  We designed a retrograde nasolabial fold island flap pedicled with the upper lip artery for repairing facial defects. The anatomy of the upper lip and the vascular supply to the nasolabial skin were observed.
  
  
  RESULTS
  All the flaps in 7 cases survived completely with satisfactory results.
  
  
  CONCLUSIONS
  The retrograde nasolabial fold island flap pedicled with the upper lip artery enlarged the rotating range of the nasolabial fold flap. The flap is recommendable for its consistent pedicle and abundant vascular supply.
