RESUMO
Objective@#This study is to investigate the effectiveness of philtrum repairment for-microform cleft lip, using muscle tension line group reconstruction.@*Methods@#This is a retrospective study of 19 consecutively primary microform cleft lip repairment patients, from January 2015 to December 2017. All the patients were provided muscle tension line reconstruction (group 1) or traditional muscle repairment by horizontal mattress sutures (group 2). The philtral ridge and dimple were evaluated by scores. The statistical analyses were performed using unpaired t-test by Prism 6.0 software.@*Results@#The philtral ridge score was higher in group 1 than group 2 (4.15±0.56 vs. 2.73±0.32, P<0.01). The philtral dimple score of group 1 increased either, when compared with group 2 (2.36±0.50 vs.1.45±0.28, P=0.0004).@*Conclusions@#Functional reconstruction of philtrum, using muscle tension line group repair, has satisfactory results in philtral ridge and philtral dimple.
