[Treatment results after zygomatico-orbital fractures].

Between 1973 and 1974, 96 zygomatic fractures were diagnosed of which 89 were surgically treated. 75 fractures were set openly and of these 65 were joined by osteosynthesis. 75 patient were examined later. Results show that posttraumatic complications occurred more frequently in fractures set without opening than in fractures set by osteosynthesis. Open reposition is therefore recommended, along with stabilization by osteosynthesis.

[Jaw metastasis of sympathicoblastoma].

Using the example of a sympathicoblastoma metastasizing into the jaw, the symptomatology of this rare location of metastases is outlined. Jaw metastases of sympathicoblastomas occur in greater numbers only in children in the age of 2.5 to 5 years. Osteolytic jaw defects and unexplainable loosening of permanent molars in children should give rise to detailed examination with regard to the possible existence of a metastasizing malignant tumor (especially neuroblastoma). Despite a solitary metastasis, early diagnosis might have a decisive influence on the otherwise lethal course of the disease.

[A modified technique of ridge reconstruction in extreme maxillary atrophy].

A ridge augmentation procedures for extremely atrophied upper jaws is presented. Compared with the use of a bone graft alone, the permanent integration of a titanium mesh reduces the loss of vertical dimension by resorption to a minimum. This is confirmed by the results of three reconstructed ridges that were followed up for 3 years. The indications and the technical procedure are discussed in detail.

[Technique and results of a one-stage procedure combining endosseous implantation (TPS) and classical preprosthetic surgery in the mandible].

Relative ridge augmentation procedures often provide a limited improvement in denture retention, due to advanced resorption of the alveolar ridge and loss of vertical bone height. The alternative treatment, i.e. integration of endosseous implants, leaves the mobile soft tissues uncapable of bearing a denture; this requires additional mucosal procedures. To avoid multiple operations we have combined the integration of frontal endosseous implants with the classical relative ridge augmentation procedure in one stage. While implantation, on the one hand, improves multidimensional denture retention, total sulcoplasty with split skin and mucosal grafts, on the other, provides a firm and strong covering of the ridge and a wider soft tissue area for denture support.
