This book has been assembled from the radiographic and photo graphic records of patients presenting to craniofacial units on four continents over 7 years. It is our purpose to illustrate a wide range of craniofacial deformities with the technique of three-dimensional com puted tomography. Many topics are briefly addressed with descriptive text intended to amplify the accompanying images but not to exclude the need for more comprehensive references as recommended in the reading list of each chapter. The ability to generate three-dimensional radiographic images rep resents a successful...
