- Abstract
- Chapter 1 is limited to a review of the literature dealing with the embryonnary and fetal skull development, particularly the neurocranial bone growth, the role of the sutures in the craniofacial growth and their obliteration, either in normal or in pathologic conditions. <BR> In chapter 2, the material under study is described, as well as the different methods, including surgical, histological and micro radiographic techniques, which have been employed to analyze the cranial vault and the sutural morphology. <BR> Chapter 3 deals with the determination of the different calcified tissues present in the human cranial vault, and their role in its growth. Calcified cartilage, as well as woven and lamellar bone, which is apposited upon the preexisting calcified tissues. Chondroid tissue, to which the responsibility of the continuous rapid growth of the cranial bones is attributed, especially in the sutural edges, is also studied. <BR> Chapter 4 concerns the histological and microradiographic study of the human metopic suture before, during and after its closure. From this study, it has been concluded that secondary cartilages are rarely present in the process of closure of the human metopic suture. On the contrary, chondroir tissue constitutes the whole of the sutural edges and interdigitations. The first microscopic signs of sutural fusion are precisely the chondroid tissue bridges. Therefore, this tissue has a main role in the normal process of metopic sutural closure in the human. <BR> Chapter 5 is devoted to the description of the metopic suture of the rat and the calcified tissues which are present in this area. In the rat, as well as in man, the presence of calcified cartilage, which is undergoing endochondral ossification, is rare. On the other hand, the presence of chondroid tissue in the metopic suture is not so evident than in man. Moreover, it seems not to take a very important role in the process of sutural closure. The results of the experience, where a part of the frontal bones were surgically isolated, prove that the sutural morphology is intrinsically predeterminated, but can be altered by extrinsic condition acting in a precise early stage of growth
