[Bronchogenic cervical cyst in a child].

Introduction: The bronchogenic cyst is a rare congenital malformation of the tracheobronchial tree. Ectopic bronchogenic cysts are extremely rare; they usually develop at the cervical level. This cyst is characterized by the presence of respiratory epithelium.

[Mountain sports: their role in 2200 facial injuries occurring over 4 years at the University Hospital Center in Grenoble].

Injuries caused by mountain sports account for many of the injuries admitted to the University Hospital of Grenoble. Out of 4,490 traumas, 470 were injuries sustained during the practice of mountain sports. While the frequency of these accidents does not evolve much, the etiological distribution depends on fashion.

[Superficial temporal venous drainage and its risks. Surgical implications].

Certain failures in scalp surgery due to defective venous drainage have led the authors to reconsider the classical anatomical data concerning the temporofrontal venous network. The study conducted in the anatomy laboratory concerned 110 superficial temporal territories injected with various coloured polymerizable substances in order to visualize this network in the skin. This study enabled the authors to describe nine types of venous drainage, the surgical implications of which are discussed.

[Three-dimensional imaging in plastic surgery. Application to the carpal bones and skull].

Since 1987, the authors have developed three-dimensional (3D) imaging of the carpus. This new application of imaging allows spatial visualization of the complex shapes of the carpal skeleton from all angles and from all illuminations. The development of this technique should lead to a better understanding of the intimate physiology of the carpus, allowing the construction of a model of the wrist enabling precise planning of operative procedures.

[Histiocytosis X of the jaws. Apropos 5 cases].

Principal features of histiocytosis X are discussed in relation to 5 cases treated in the department. Clinical signs are known. Bone scintiscans are of importance for evaluation of extension of the disease.

[Benign metastatic ameloblastoma. A case report and review of the literature].

A 78 year old woman with a history of maxillary ameloblastoma from age of 38 years was found on routine examination to have a pulmonary image of the balloon release type. The lesion was atypical with respect to its clinical tolerance and slow progression. Pathology of several nodules removed by surgical lung biopsy confirmed the benign nature and identity of the maxillary and pulmonary lesions.

[The temporal muscle flap and palatal repair].

Two edentulous elderly women presented with benign but extensive tumors of middle third of face. The excision necessary for reasons of comfort and hygiene could not be envisaged unless the ineluctable vast palatine breach opened could be immediately repaired by surgery, any prosthetic solution being excluded. The use of a total temporal muscle flap, without zygoma section, provided an effective and comfortable solution to this both delicate and unusual problem.
