title: [A modified Onizuka cheiloplasty for repairing the unilateral cleft lip].
abstract: OBJECTIVE
  To explore the surgical technique of a modified Onizuka cheiloplasty for repairing the unilateral cleft lip.
  
  
  METHODS
  24 patients with unilateral cleft lip were repaired by modified Onizuka cheiloplasty. The rotation flap ended at the midpoint of nasal columella crease. A small triangle skin flap was formed above the vermilion border of the advancement flap. The small triangle flap was inserted to the medial side after the Cupid's bow was built. The skin of the flap C was denuded along the nasal columella crease and the muscle was sutured to the alar base for augmentation of nostril floor on the cleft side. The tip of the advancement flap was sutured at the midpoint of nasal columella crease and the skin of nasal floor was trimmed to hide the incision line around the nasal columella base.
  
  
  RESULTS
  It was found that the Cupid's bow was rebuilt in a natural form and the configuration of the upper lip was reconstructed symmetrically. The long term follow up studies showed that the philtrum column was not disturbed by the small triangle flap and the nasal floor was rebuilt without obvious scars.
  
  
  CONCLUSIONS
  The modified Onizuka cheiloplasty is an easy learning technique and efficient for repairing the unilateral cleft lip. This technique can satisfy the patients by reducing the length of scar as well as rebuilding a natural form of upper lip and nostril floor.
