Abstract: Objective To investigate the nasolabial muscle anatomy and biomechanical characteristics.Methods Micro-computed tomography scan was performed in 8 cases of spontaneous abortion fetus lip nasal specimens to construct a three-dimensional model.The nasolabial muscle structure was analyzed using Mimics software.The three-dimensional configuration model of nasolabial muscle was established based on local anatomy and tissue section,and compared with tissue section.Three dimensional finite element analysis was performed on lip nasal muscle related biomechanics and surface deformationin Application verification was carried out in 263 cases of microform cleft lip surgery.Results There was close relationship between nasolabial muscle.The nasolabial muscle tension system was constituted,based on which a new cleft lip repair surgery was designed and satisfied results were achieved.Conclusions There is close relationship among nasolabial muscle in anatomy,histology and biomechanics.To obtain better effect,cleft lip repair should be performed on the basis of recovering muscle tension system.
