[Fractures of the zygomatic bone].

Under study were 248 patients with fractures of the upper and middle zone of face including injury of the zygomatic bone. The examination performed has revealed a joint character of the injury of the zygomatic bone and the maxillary sinus walls. The rational grouping of fractures of the zygomatic bone includes isolated fractures of its processes and lower edge of the orbit as well as fractures of the zygomatic-maxillary complex.

[The x-ray diagnosis of isolated and combined fractures of the naso-orbital area].

Fifty-two patients with naso-orbital fractures were examined. Regularities in isolated and multiple injuries of such bones were detected. Specific features of the injuries of individual osseous structures of the naso-orbital complex in various types of fractures were analyzed.

[Radiodiagnosis of Le Fort type fractures].

Le Fort's fractures of maxillary bones are referred to grave injuries that require an accurate and urgent diagnosis. A total of 70 patients with different variants of such fractures were examined. The x-ray examination included polypositional roentgenography, linear tomography and panoramic sonography with the Sonarc apparatus.

[The diagnosis of fractures of the anterior cranial fossa in craniofacial trauma].

The authors examined 436 patients with acute trauma of the upper and middle zones of the visceral cranium. Injury to the anterior cranial fossa was discovered in fractures of the orbitonasal complex, isolated fractures of the upper zone, fractures of the Le Fort II and Le Fort III types, and multiple fractures of the upper and middle zones of the face. Such fractures were found in 158 cases, in 76 of them (48.

[Panoramic zonography in the diagnosis of orbital fractures].

A total of 453 patients with acute injuries of the upper and median zones of the facial skull were examined. The most frequent injury was that to the orbital entrance, fractures of the inferior wall; fractures of the exterior, interior, and anterior walls were less incident, and fractures of the orbital apex were the most rare. Types of the skull bone fractures, associated with injury to the orbital walls, were distinguished.

[Panoramic zonography in the diagnosis of blowout fractures of the orbit].

Altogether 32 patients with blow-out fractures of the orbit were investigated, using an x-ray study that included panoramic zonography. Isolated blow-out fractures and blow-out fractures combined with injured adjacent facial bones, were singled out. X-ray signs were divided into direct ones, characterizing a parietal fracture, and secondary ones, determined by secondary traumatic changes.
