[Risk evaluation of neoplasms relevant to jaw surgery].

The authors evaluate the risks of tumours and growth processes in the maxillofacial region. The tumours and growth processes in question are so-called semi-malignant tumours with tendency to locally limited infiltration, intra-epithelial carcinomata, precanceroses with abnormal epithelial growth and usually benign tumours with increased risk of degeneration. The clinicopathologica characteristics of these neoplasms are discussed, and recommendations for discriminating therapy are given. The clinician should use, by early detection and treatment, the primarily lower riskiness of these processes for the complete healing of patients affected with these diseases.

Intraosseous benign neural sheath neoplasms of the jaws. Report of seven new cases and review of the literature.

Benign neural sheath neoplasms occurring centrally within the jaws are most uncommon. Our search of the English-language literature revealed twenty-eight previously reported cases. Seven additional cases--five neurofibromas and two neurilemmomas--are newly described here. Most cases have not been associated with multiple neurofibromatosis. These tumors occur predominantly in females, in patients under 45 years of age, and in the posterior mandible. The tumors generally present as asymptomatic radiolucencies, but some are associated with pain and/or swelling. Neurofibromas tend to recur more often than neurilemmomas when treated by conservative local excision.

[Treatment of advanced neoplasms in the jaw].

Report is made about the combined therapy with cytostatics (methotrexate - bleomycin) and irradiation in patients with extended tumors in the gnathic region. Ten patients in whom a radical therapy with conventional methods did not promise any success, were treated with intra-arterial infusions of methotrexate and bleomycin and simultaneous irradiation. At present, eight patients are tumor free (observation time 4-14 months after termination of therapy). Although radiation doses and doses of cytostatics were high, only insignificant side effects were stated; consequently, the treatment had to be terminated in none of the patients.

Periosteal benign osteoblastoma of the mandible. Report of a case and review of the literature pertaining to benign osteoblastic neoplasms of the jaws.

A case of periosteal benign osteoblastoma arising in the mandible of a Caucasion male aged 9 years is presented. A review of the literature has produced 24 additional benign osteoblastic neoplasms of the jaws which have been delineated as osteoblastoma or osteoid osteoma. There seems to be a predilection for these lesions to occur in males and in the mandible. Osteoblastomata occur most frequently in patients under 20 years of age whereas osteoid osteomata arise mainly in persons over 25 years of age.

High-dose rate intracavitary radiation therapy for advanced head and neck tumors.

Fifty-seven treatments were performed on 27 head and neck pateints with recurrent or residual tumors on a high dose rate, remote controlled afterloading unit: There were 16 cases of maxillary sinus tumors, 6 epipharynx, 3 alveolar ridge, 1 hard palate and 1 floor of mouth. All patients have been followed up more than 2 years except one. Five patients are alive without local recurrence for more than 2 years. In 13 patients local tumors disappeared once and normal mucosa covered the tumor sites. Two patients died from local bleeding. In six patients this method failed to destroy tumors. Our prupose was palliative local control: therefore, in two-thirds of cases treated we were successful with this easy method of nonfractionated acute intracavitary radiation. This result is favorable, considering that all cases treated here were failures following full dose external radiation, although the treatment had to be repeated more than twice in 15 cases. Relief of symptoms is excellent when this therapy is used.

Radiotherapy in osteosarcoma.

Radiation therapy in the treatment of osteosarcoma has been considered with respect of the subclinical metastatic disease in the lung and the primary lesion. Emphasis is given to the necessity of coordinating the management plan of the primary lesion with an adjuvant program. Evaluation of the efficacy of a conservative treatment of the primary lesion by radiation therapy and chemotherapy is considered a proper subject for clinical study. A proper biopsy technique and several practical aspects of technique of radiation therapy in management of osteosarcomas of bone are important factors in survival time of individual patients.

Facial bone scintigraphy. II. Diagnostic potential in neoplastic and inflammatory lesions.

From a series of about 200 facial bone scintigraphies, 32 patients were selected to demonstrate the uptake of 99Tcm-diphosphonate in various inflammatory and neoplastic diseases in the sinuses and oral cavity. The method was found of value in separating patients with inflammatory involvement of the bone from those without, as well as in assessing possible bone involvement in malignant lesions.
