Abstract: Objective: To provide a theoretical reference for the clinical treatment and efficacy assessment of unilateral complete cleft lip by mastering the characteristics of the lip nasal soft tissue profiles of the infants with unilateral complete cleft lip and palate (UCLP). Methods: 92 infants with UCLP were randomly selected, measured the lip nasal soft tissue profiles directly and compared with normal control group. Results: The mean value and standard deviation of 28 facial basic measurement indexes were obtained from normal infants and infants with UCLP. We compared the measurements of UCLP group with normal group. Three indexes including lateral upper vermilion heigh in the affected side, upper lip height in the unaffected side, the nose bottom width in the unaffected side, were not significant different. The other indexes were statistically significant different (P<0.01). The correlation analysis of measurements in UCLP group showed that there were correlations and statistically significance among several indexes. Conclusion: UCLP was a complex lip-nasal deformity, formed a whole in three dimension. It displayed tissue defect and displacement. The measurement indexes differed greatly, but there was a obvious positive correlation between paired indexes of the same individual.
