Abstract
In this study of septomaxillary relationships, the nasal septum was resected in 6 2- to 4-mo.-old chimpanzees. Data were obtained through the use of lateral cephalograms and dental casts. Results of this 3-yr longitudinal study indicated no significant differences between control and operated animals in the linear regression equations (y = a + bx), which describe anterior facial growth. Manipulation of the cartilaginous nasal septum may be tolerated during human reconstructive surgery; the role of the septal cartilage differs from that in baboons and other nonprimate models.
