This book explores craniofacial anatomical variations using photographic images, three-dimensional images, and computed tomography reconstruction, giving the reader a better understanding of the craniofacial structures involved in each type of facial cleft, their phenotypic variations, and their associations with other rare facial clefts. This will also aid the visualization of the relationship between tissue and bone changes. This book, through providing in-depth knowledge of the morphology of rare facial clefts, aims to contribute towards the establishment of personalized and individualized therapeutic practices in highly complex cases of facial clefts, and the improvement of the rehabilitation process for the patients.
