The main intention is to provide structural stability and to straighten the nasal septum. Deformity or excessive deformation of the L\u2010strut might cause functional or aesthetic complications. The objectives were to examine the effects of material properties, the boundary conditions, the nasal tip support, and the geometry of the L\u2010struts on the deformity of septal L\u2010struts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design:<\/jats:title><jats:p>Computer\u2010aided modeling was used to create a spring\u2010supported nasal tip and free nasal tip L strut septal cartilage models upon which simulation was performed to analyse the deformation patterns.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>A five\u2010sided septum model was first created from the computed tomography scan of a human subject. Several models with various combinations of wider or narrower dorsal struts as well as arc of cartilage were then constructed from this septum model. The edges connected to bony supports were assumed to be fixed, and the nasal tip was assumed to be spring supported. Finite element analyses were carried out to determine the deformation and stress distribution in the septal strut for different combinations of material properties and nasal tip spring support.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>The spring\u2010supported nasal tip model provides a more accurate representation of the boundary conditions in the nose. In both the free and spring\u2010supported nasal tips\u2014the BC junction and the nasal spine are found to be the consistent points of maximum stress regardless of material properties. The preservation of an arc of cartilage and a wider dorsal strut increase the stability of the structure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>The introduction of a spring\u2010supported nasal tip model provided a more accurate representation of the boundary conditions in the nose.
