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.
