“…The nasal septal traction model emphasizes the morphogenetic capacity of the nasal septum and considers the midface, including the premaxilla, as responsive to developmentally induced biomechanical forces placed on the facial skeleton (e.g., along the premaxillary suture) during septal expansion (e.g., Scott, 1953). Thus, as the nasal septum increases in length, tension is placed on the premaxilla via the septo-premaxillary ligament (Latham, 1970;Gange and Johnston, 1974;Siegel, 1986, 1991;Siegel et al, 1990). This dynamic results from the nasal septal cartilage acting as a growth plate, which develops through a combination of interstitial cellular division, chondrocyte hypertrophy, and endochondral ossification along its caudal border (Scott, 1953;Baume, 1961;Catala and Johnston, 1980;Copray, 1986;Wealthall and Herring, 2006).…”
