[Developmental disorders of the permanent dentition following fractures of the visceral cranium during the growth period. Incidence and morphological findings].

The retrospective examination of 70 patients who had suffered fractures in tooth-bearing segments of the maxilla and the mandible when they were between one and twelve years old revealed a high incidence of late pathologic changes (in 39 out of 70). Disorders in odontogeny, eruption of the teeth and occlusion were observed. Primary and secondary loss of teeth did also occur. Our results show the necessity to inform both the young patients and their parents about the high incidence of late changes after jaw fractures in childhood. An effective recall-system is required in order to diagnose and treat such changes as soon as possible.

[Treatment of implant-induced pain conditions in the maxillofacial area].

The implantation of dental implants may lead to severe pain syndromes (not reckoning postoperative pain and discomfort). Pain in the upper jaw is usually caused by inflammations like sinusitis, often in combination with an oroantral communication, rhinitis and osteitis, whereas pain in the lower jaw is often caused by injuries of sensitive branches of the mandibular nerve, mostly the inferior alveolar nerve. In these cases the therapy of pain should be causal, which means removal of the implant and treatment of the pathologic consequences of implantation. Especially the possibilities of micronerval surgery are emphasized within this article.

Hairy cell leukemia with an autoimmune syndrome, paraproteinemia, and cryoglobulinemia.

We have described an 82-year-old man with HCL who had autoimmune manifestations, paraproteinemia, and cryoglobulinemia. Chemotherapy resulted in a dramatic response, with a decrease in the tumor mass, a reduction in the clinical and serologic features of the autoimmune syndrome, and disappearance of the cryoglobulin, but without a significant change in the serum level of paraprotein.

[Fracture of the mandible in osteogenesis imperfecta].

This article is a report on a fracture of the lower jaw in osteogenesis imperfecta. In this disease, fractures of the facial part of the skull are very rare, in contrast to fractures of the extremities; they may possibly occur in adults only if the bone is weakened by additional processes--in the present case, by an odontogenous cyst. In the case described here, successful treatment of the fracture could be effected via intraoral approach by means of a functionally stable osteosynthesis performed with plates.

[Pathogenesis and clinical manifestation of the styloid syndrome].

The styloid or Eagle's syndrome is a uncharacteristic pain and dysfunction syndrome of the head and neck. Symptoms, differential diagnosis, etiology and pathogenesis are discussed. 9 cases are presented with special consideration of the operative treatment, 6 cases were treated via an extraoral, 3 via an intraoral incision. Along with the intraoral approach one major complication, a thrombosis of the internal carotid artery, was observed. After one extraoral approach a minor complication, a temporary irritation of the hypoglossic and lingual nerves, occurred.
