Figure 17: (a) Lateral view of an adult rabbit skull 20 weeks after resection of the middle one-third of the septum cartilage. Shortened nasal dorsum with “saddle”. Malocclusion with cross bite of incisors. (b) Graphic representation of the mean coordinates of 19 measuring points on the lateral side of the skulls; N (nasion), N1-6 (points on the internasal suture at 5 mm from nasion and 5 mm between consecutive points), SM (anterior of zygomatic process) and PT (posterior point of zygomatic process; control group (thin line) compared with experimental (thick line) group (resection of 10mm) with 95% elliptiform confidence areas of the variety of the X and Y coordinate of the measuring points). (c) Overprojection of diagrams of the skulls in 4- and 24 week-old unoperated animals and after resection of middle one-third of the septum. SSO-SL has been used as reference. Interruption of the anteroposterior axis of the septum by partial resection (central one-third) prevents further ‘extra growth’ of the nose and paemaxilla/maxilla.
