title: [A study of individual operation designs for unilateral cleft lip repair].
abstract: OBJECTIVE
  To formulate a reasonable and effective individual operation design that can be adaptable to various forms of deformity of unilateral cleft lip.
  
  
  METHODS
  The unilateral deformity of unilateral cleft lip was classified into four types (Type I, II, III, IV) according to the distances from the midpoint of the base of columella and the points of alar bases respectively to cupid's bow peaks of both sides. Furthermore, according to the characteristics of deformity, four types of operation were designed respectively under the standard of making both cupid's bow peaks along cleft drop in the same levels, and the essentials were restoring and making the distances from the midpoint of the base of columella and the points of alar bases to both cupid's bow peaks symmetric.
  
  
  RESULTS
  Type I operation was almost the same as the Millard's operation design, and the basic designs of Type II and Type IV operation were also the same as the Millard's operation design, but were combined with the Tennison's operation design. Type III operation was a new operation design of unilateral cleft lip repair.
  
  
  CONCLUSIONS
  The individual operation design in unilateral cleft lip repair should be definitely according to the characteristics of cleft lip deformity.
