[Evaluation of intratumoral bleomycin application in a tumor model and in a clinical pilot study].

In a total of 21 patients with squamous cell carcinomas of the oral mucosa 26.9% of the total volume of 57Co-Bleomycin injected into the tumor was found in the blood as early as 10 min following injection. Examinations using a gamma camera demonstrated that 94.

[Retrospective multicenter study on carcinomas of the lips and oral cavity. The role of multiple malignancies].

In a retrospective multicenter study the role of multiple cancer has been assessed in 2481 patients with carcinomas of the lips and oral cavity. In 3.2% of the cases the malignancies developed outside the maxillofacial area.

[Multicentric retrospective study on the carcinoma of lips and oral mucosa. Analysis of coherence between pre- and posttherapeutical categories of classification].

The coherence between prae- and posttherapeutical TNM findings had been checked up in a multicentrically registered patient material of 2,481 non-praetreated plate epithelium carcinomas of the lips and oral mucosa. Whereas the extension of the tumour has in the main been the same, the findings on lymph nodes had a trend showing essential deviations. In a two-dimensional examination of 851 histologically prepared preparations of lymph nodes, a prognostic relevance acc.

[10 years' experience of cryosurgery in the maxillofacial area].

The author informs through statistical statements about the ten years use of cryosurgery in the maxillofacial region and discusses and analyses the cryotherapy of selected groups of affection. Affections of any superficial, but of minor depth-effect--for instance leukoplakias--may generally be treated cryosurgical with much success. Good results are obtainable also with soft neoplasms, as hemangiomas, where distinct functional and aesthetic advantages are emphasized.

[Phantom head used to acquire skill in local anesthesia in the mandibular and maxillary regions (author's transl)].

This paper describes a phantom head used to acquire skill in local anesthesia in the mandibular and maxillary regions, thus helping students in putting theoretical knowledge into practice. An electric display device enables the student's proficiency level to be determined objectively. Five years' clinical testing of the phantom in the practical training of students shows the advantages of simulatory methods of training.
