PREFACE
This monograph deals with a selected, specialized body of information. It is not intended to be an encyclopedia of factual and historical data covering all facets of craniofacial biology. The objective is to describe and illustrate a particular, fundamental mode of approach to the study of craniofacial growth. The contents describe primarily the complex behavior of bone tissue during the growth of the skull.
Basic principles and concepts are emphasized throughout. The general approach is that of a morphologist concerned with postnatal morphogenesis, and the particular points of view are based largely on the author's own investigations of bone remodeling and growth mechanisms in the human craniofacial skeleton.
By request, Dr. W. Stuart Hunter has prepared a special chapter on basic cephalometric techniques and procedures. It is felt that an introduction to the fundamentals will be useful to those lacking knowledge of this essential subject. It will also provide an introductory overview for individuals planning to specialize in this field.
Background training in the structure, growth, and remodeling of bone varies widely among the different workers in the field. The introductory chapters in this monograph are provided for those who wish to expand the scope of their understanding. For those already knowledgeable in the subject these chapters will also serve as a review of relevant terms and concepts used in later sections. It has been the author's experience that bone descriptions in most elementary histology courses are generally inadequate for an advanced-level understanding of craniofacial bone growth. Such course traditionally dwell on the structure of the Haversian system and the different zones in the epiphyseal cartilage. Beyond this, a comprehension of the truly dynamic qualities of bone and the many versatile mechanisms utilized in its growth and remodeling become difficult for the beginning student to appreciate and understand, particularly during rapid survey courses. The time given to the different basic sciences in current medical and dental curricula is continually being reduced, and additional effort has become required on the part of the individual to further his own knowledge of the fundamentals of craniofacial bone growth.
Because bone is hard, it represents a specialized kind of tissue. Because it is hard, bone has to it. Because bone has a hard calcified matrix, it has special processes of growth. These processes are clear cut and follow a welldefined, straightforward sequence. They are complex but can be readily traced if underlying principles, described in the first part of this monograph, are well understood. Part I is a consideration and an evaulation of bone from the standpoint of its behavior during skeletal morphogenesis. It is not intended as an elementary account. On the contrary, it is presumed that the reader already has a reasonable knowledge of this tissue and the vocabulary pertaining to it. The purpose is to go beyond standard textbook accounts in order to establish a special yet fundamental body of information prerequisite to dealing with the specialized topics discussed in Part II.
Part II deals with an analysis of growth in the human craniofacial skeleton. It gives a detailed account of events involved in the maturation of each individual bone in the skull. No attempt has been made to include all viewpoints pertaining to facial growth since the objective is to provide a specialized reference book giving specific attention to this one facet. When the principles given in Part I and the application of these principles are considered together, the underlying nature of craniofacial bone growth can be visualized in more meaningful perspective. How these concepts are involved in the growth of bones in the human skull and what happens to the bones themselves as they grow are the particular subjects of this book.
