Abstract： We are no longer entangled in the anatomical resetting of the labial-nasal muscle itself,but the sight to the muscle fiber level,to study the relationship between the muscle fiber force line and the labial-nasal shape.In the past ten years,we focused on the lip of nasal muscle fiber anatomy,imageology and biomechanics,carried out a series of research works,realized the three-dimensional (3D) visualization of small labial-nasal muscle fiber,established configuration models of normal and cleft lip with nasal muscle fibers,and put forward the hypothesis of naso-labial muscle tension band.According to the biomechanical parameters of lip nasal muscle,cartilage,skin and subcutaneous tissue,we initially established a biomechanical model elaborating the relationship between labial-nasal muscle tension lines and surface morphology;we summed up three muscle tension group which determines labial-nasal contour,explained the biomechanical mechanism in cleft lip and various lip nasal deformities,and realized the possibility to freely change the 3D labial-nasal contour by lip nasal lip nasal muscle tension theory;Finally we carried out clinical validation in clinical treatment of cleft lip,achieved the effect of detail cleft lip repairing.
