Sagittal Growth of the Nasomaxillary Complex during the Second Trimester of Human Prenatal Development.

چکیده
Numerous investigations have been reported on the embryonic development of the human cranium and on the sequential appearance, number, and location of primary ossification centers in component bones of the facial skeleton.'-6 In general, these studies were exclusively qualitative and non-metric in content. Relatively few attempts, however, have been made to measure the changes in size, form, and proportionality of the upper facial region during human development.7-1i The purpose of the present study is to describe the patterns of growth in the craniofacial region during the second trimester of prenatal development. For this purpose a series of linear and angular analyses of the cranial base, nasal septum, and palate have been used. In addition to describing patterns of prenatal nasomaxillary growth, the findings of this study were correlated, whenever possible, with reported studies of craniofacial growth during the neonatal and early childhood periods. Consequently, the analyses used herein were adapted from cephalometric growth analyses currently recognized in orthodontics (Krogman and Sassouni).12 Furthermore, this study was founded on the concept that growth of the human body and, more specifically, the craniofacial region is a dynamic biological continuum that begins in embryonic development and continues through senility.
