Neck injuries: I. Occipitoatlantal dislocation--a pathologic study of twelve traffic fatalities.

Twelve of 155 persons killed in traffic crashes had occipitoatlantal dislocations. Nine were vehicular occupants, 2 were cyclists, and one was a pedestrian. The dislocations involved various combinations of lacerations of the alar ligaments, the occipitoatlantal joint capsules, the dura mater, the tectorial membrane, the rectus capitis muscles, and the suboccipital muscles. In 2 instances, an occipital condyle failed instead of the corresponding alar ligament, producing condyle fractures. Atlas ring fractures occurred in 3 instances. Axial and subaxial cervical trauma were uncommon. Facial or mandibular fractures occurred in a majority of cases, vault skull fractures were uncommon, and basilar fractures were absent. Pontomedullary brainstem lacerations occurred in 9 of the 12, and 4 had midbrain lacerations. The majority of the victims succumbed to acute neurogenic shock as the sole or the major mechanism of death. The biomechanical basis for occipitoatlantal dislocation is discussed, and the author suggests that distraction, in concert with variable combinations of extension, rotation, and posterior translation is responsible for occipitoatlantal dislocations.

[Radiographic examination of middle face fractures].

Radiography plays a critical role in the management of traumatic injuries to the facial bones. Injuries of the face and jaws require highly specialized technical treatment that is directed toward the establishment of normal function of the jaws and teeth and the prevention of infection and facial disfigurement. The face and especially the jaws present unusual difficulty in Radiographic examination and many different projections have been described to show the maxilla and the mandible. The clinician should be familiar with these projections in order to achieve useful information. In this study after a brief introduction to the fractures of the middle third of the face, the basic projections for the radiographic examination are presented.

Management of intraoral injuries.

Primary closure of intraoral wounds can be done up to 24 hours after the injury. A mucosal seal decreases the possibility of infection and allows the wound to heal more rapidly and less painfully than a wound left open to heal by secondary intention. Defects of the lips must be closed with exact alignment of the vermilion-cutaneous margins. Nerve repairs must be done without tension at the repair site. Parotid duct repairs are mandatory to prevent cyst and fistula formation. Anterior permanent teeth may be replanted.

[Distinctive nature of mountain sport maxillo-facial injuries (author's transl)].

Mountain sports were the cause of 400 facial injuries treated in he Maxillo-facial Surgical Unit in Grenoble over a period of 5 years. Deltaplane injuries are becoming more frequent. Isolated facial injuries represent 57 p. cent of the cases treated. The various types of lesions encountered are described, and the distinction drawn between those treated as emergencies, and those for which urgent treatment could be delayed.

[Hyperplasia of the coronoid processes of the mandible--case-history].

Hyperplasia of the coronoid processes of the mandible in a 36-year-old man was associated, in addition to difficult opening of the mouth, with noises of apparently articular origin. The noise was due to the shifting of the coronoid processes along the inner surfaces of the temporal processes of the facial bones. On the X-ray picture also the elongated styloid processes were striking as well as symmetrial exostoses at the lower borderline of the mandible and condylar processes deformed without any apparent cause.

Histiocytosis X. VII. Prognostic significance of skull lesions.

The significance of bone lesions in the skull as a possible prognostic factor in patients with histiocytosis X was examined in 64 patients, of whom 29 had such lesions. Lesions localized to the skull cap or facial bones were associated with a good prognosis whereas those in the base of the skull had a prolonged course or even a fatal outcome.

[Reparative regeneration of the maxilla following osteotomy under conditions of controlled measured distraction (an experimental study)].

The authors have for the first time developed a device and created an experimental model of osteotomy in 13 adult mongrel dogs for comprehensive (radionuclide, x-ray, histologic, neutron-activation methods) investigations of the time course of reparative regeneration of maxillary laminar osseous tissue in conditions of perforating osteotomy, followed by dosed distraction (0.75 mm in 48 h by the device activation twice a day). The tension and stretching factors were found conducive to bone formation in the laminar osseous tissue. Based on these data, new osteotomy methods may be developed and the existent ones improved, as well as the methods for the treatment of patients with facial bone defects and deformations, based on the distraction methods of treatment.
