Book Description
La position antéro-postérieure des lèvres supérieures et inférieures est une caractéristique clé pour déterminer la beauté d'un visage. Les analyses esthétiques établies au milieu du XXe siècle à partir d'une population caucasienne font encore référence aujourd'hui. Les plus utilisées sont celles de Ricketts, Steiner et Burstone. Elles formalisent de façon simple l'évaluation du profil labial cutané dans le sens sagittal et déterminent le diagnostic de prochélie, normochélie ou rétrochélie dont découle le plan de traitement orthodontique. Cependant, elles ne prennent pas en compte le recul sénescent du profil en lien avec le vieillissement du sujet. Après analyse de la littérature, la contribution des lèvres dans l'esthétique du profil cutané varie selon le juge et le caractère polyethnique de la société. L'utilisation des lignes esthétiques comme seul argument d'un repositionnement dentaire semble aujourd'hui injustifiée. L'orthodontiste, afin d'améliorer son diagnostic et définir ses objectifs de traitement, doit anticiper le vieillissement labial du patient. Ceci va de pair avec un regard nuancé à porter sur les analyses céphalométriques.

Book Description
The European Register of Cleft Lip and Palate Services will be produced as a result of the concerted action project: Standards of Care for Cleft Lip and Palate in Europe: EUROCLEFT funded by the European Commision under its BIOMED II and INCO COPERNICUS programmes. The project, aimed at developing a network of cleft care teams across Europe, ran for three years between 1996 and 1999 and aimed broadly to improve the effectiveness and efficiency of care for European children with clefts of the lip and/or palate. Clefts of the lip and/or palate are birth defects affecting 1:500 live births. Successful rehabilitation requires a complex multidisciplinary mix of services.

Book Description
The phylontogenic theory proposes an original understanding of nose, sinus and midface formation and development by looking back in evolution for the first traces of the olfactory organ and then tracing its successive phyletic transformations to become part of the respiratory apparatus and finally the central point of human facial anatomy. Von Baer’s, Darwin’s, Haeckel’s, Garstang’s, Gould’s and Buss’ explorations of parallels between phylogeny and ontogeny help to trace the nose and midface story. The paradigm of existing parallels between ontogeny and phylogeny proves useful both in seeking to understand the holoprosencephalic spectrum of facial malformations (which represent radically different pathways of facial development after the life’s tape has been started to run again) and in formulating hypotheses on chordate to vertebrate evolution. The phylontogenic theory leads to new medical hypotheses on nose and sinus diseases and opens the field of evolution and development-based medicine.

Book Description
This Atlas depicts in a clear manner the use of regional skin, muscle and musculocutaneous flaps as well as donor sites from distant regions of the body where vascularized skin, muscle, bone, and nerves can be harvested and transferred to the head and neck. Otolaryngologists, plastic surgeons and general surgeons use both regional and free flaps to reconstruct damage to the head and neck caused by cancer and trauma. This Atlas provides the surgeon with techniques for mastering different donor sites needed to find solutions to virtually every reconstruction problem. It provides detailed descriptions of the anatomy and harvesting techniques of the major regional and free-flap donor sites currently employed in head and neck reconstruction.

Book Description
Neglected finger injuries may lead to chronic lesions that often have detrimental consequences for the practice of a ball sport, whether at a recreational level or at the top athlete level. The initial injury management is crucial. Depending on the type and the severity of the lesions, different people may get involved: the players themselves or their entourage, physiotherapists, club doctors, emergency physicians, family doctors, sports doctors or hand surgeons. Treatment is usually conservative: the long fingers require rapid mobilization to prevent stiffness and contrary to that, the thumb requires stability. Surgery may be necessary to reach these goals especially for athletes, because of the demands of their sport. Chronic lesions are also in part related to repeated trauma, requiring specialized long-term multidisciplinary treatment. They can often lead to the end of a sporting career, but also may limit the functionality of the fingers at the time of conversion. Dr Chick is Consultant Hand Surgeon in Hôpital de la Tour (Geneva) and Clinique de Genolier, Switzerland, and Visiting Surgeon in Aspetar, Orthopaedic and Sports Medicine Hospital, Doha, Qatar.

Book Description
According to reports in the literature, despite the severe disruption of carpal anatomy, fracture-dislocations of the wrist are missed on clinical and radiographic examination in a high percentage of cases. Orthopedic surgeons’ lack of familiarity with these injuries is one of the factors contributing to failed or delayed diagnosis. This richly illustrated book covers all types of wrist dislocation and fracture-dislocation. Detailed information is provided on anatomy and biomechanics, while terminology and classification of injuries are explained. Treatment options are thoroughly analysed, with special emphasis on surgical treatment, which is presented step by step. All of the figures – radiological and surgical – relate to patients treated by the author himself. Most of the cases are from the Red Cross Hospital of Athens that admits many patients with such injuries, in part through referral from other centres due to the author’s acknowledged expertise in the field. This volume, with its highly informative and up-to-date chapters and reviews, and a wealth of color figures, will be of great practical value for clinicians and residents in orthopedic surgery, who assist them in daily decision making.

Book Description
In review, the amount of information available on the morphological and func tional properties of the frog nervous system is very extensive indeed and in certain areas is the only available source of information in vertebrates. Further more, much of the now classical knowledge in neurobiology was originally ob tained and elaborated in depth in this vertebrate. To cite only a few examples, studies of nerve conduction, neuromuscular transmission, neuronal integration, sense organs, development, and locomotion have been developed with great detail in the frog and in conjunction provide the most complete holistic descrip tion of any nervous system. Added to the above considerations, the ease with which these animals may be maintained (both as adults and during development) and the advantage of their lower cost as compared with other vertebrate forms make the frog one of the most important laboratory animals in neurobiology. With these thoughts in mind, we decided to compile this volume. Our goal in doing so was to assemble as much as possible of the information available on frog neurobiology and to have the different topics covered by authorities in each of the fields represented. To keep the handbook restricted to one volume, we found it necessary to omit the large field of amphibian muscle neurobiology, which has already been summarized in various other publications.

Book Description
Was ever a foreword requested for God's words? It is not indecent to write a preface for Hugo's "Growing Mandible"? After training in the Jaw's Old Testament, Hugo is writing the New One that he taught for 40 years long. Indeed, the last decade has been fertile in mechanical gadgets which have made diagnosis and surgery easier, such as, accurate CT 3-D images, and absorbable plating or osteodistraction, which brings a fine touch to treatment timing in children. However, all of this does not encompass the intellectual process, basic principles, tactics and procedures.

Book Description
This book provides comprehensive coverage of current topics in idiopathic scoliosis (IS). A three-dimensional deformity of the spine, the condition is characterized by lateral curvature combined with vertebral rotation. The primary lesion, however, lies in the median sagittal plane, taking the form of a lordosis. Although the clinical manifestations of scoliosis have been well documented, its cause and pathogenesis have not yet been determined. Research into what causes IS has focused on the structural elements of the spine, spinal musculature, collagenous structures, the endocrine system, the central nervous system, and genetics. Results of these studies have brought about a new perception of IS epiphenomena, but the main cause of IS remains unknown. Recently, several investigators have produced new hypotheses regarding the cause of IS using the developing techniques of genetics, biochemistry, and neurology. This book is a review of the various causative factors thus far proposed for IS and an introduction to the directions in which research is heading to determine the primary cause of IS.
