Abstract: Objective:To develop a perioral force measurement system for the infants with cleft lip and palate.Methods:The peri-oral force measurement system of infant with cleft lip and palate is composed of hardware and software.The sensor is metal cantilever. The measurement ranges are 0 -20 and 0 -1 00 g/cm2 ,and the precision is 0.1 g/cm2 .The system was used in 4 cases of infants with unilateral cleft lip and palate before and after cheiloplasty.The results were analyzed by SPSS 1 9.0 software.Results:Before cheilo-plasty the perioral force of labial frenum area was (1 .79 ±0.94)g/cm2 ,that of angulus oris area of normal side and cleft side was (5. 41 ±1 .01 )g/cm2 and (3.1 2 ±1 .55)g/cm2 (P <0.05);after cheiloplasty:the perioral force of labial frenum area was (1 2.73 ±3. 51 )g/cm2 ,that of angulus oris area of normal side and cleft side was (7.64 ±1 .64)g/cm2 and (7.27 ±1 .89)g/cm2 .Conclusion:The perioral force measurement system can be used to measure the perioral force of the infants with cleft lip and palate.
