title: [Effects of unilateral cleft lip and palate prosthesis on the development of maxillary and facial soft tissue].
abstract: OBJECTIVE
  The effect of unilateral cleft lip and palate prosthesis on the development of maxillary and facial soft tissue was investigated.
  
  
  METHODS
  The standard cephalometric measurement was used in patients with complete unilateral cleft lip and palate operated in different periods. We obtained data by measurement.
  
  
  RESULTS
  Hard tissue: ANS-X, PNS-X and N-ANS in the group of patients were statistically different from those of the normal control group, but in ANS-PNS and N-PO, there is no statistical difference in these two groups. Angles of hard tissue: There is statistical difference in < N. W. ANS and < SNA between the control and the group of patients. There is only statistical difference in < SNB between the D group and the control group. There is no difference among other groups. Ratios of hard tissue: The ratios of ANS-X/S-X and PNS-X/S-x in the control group were higher than those of the group of patients, and the ratios of S-Go/N-Po, Ar-Go/N-Po and N-Po/AN in the group of patients were higher than those of the control group. The ratio of NMC/SUBN: It is the highest ratio in the control group, and there is no difference between ratios in the control group and the C group, but there is statistical difference between the control and other patient groups (P < 0.05).
  
  
  CONCLUSIONS
  Comparing with normal persons, the defect of maxillary length development is apparent in the patients with complete unilateral cleft lip and palate due to congenital development deformity. The figure of soft tissue in patients with unilateral cleft lip and palate is anastomotic with the figure of their hard tissue. The excavation of bony middle 1/3 in face results in paramorphia of soft tissue adhering on the bony tissue. We can conclude that in order to obtain better articulation function, the palatoplasty should be carried out early.
