[Results of an analysis of waiting time at a maxillofacial surgery outpatient department of a university hospital].

Waiting periods in public health institutions not only stress the patients and the personnel, but they are also attended by considerable economic disadvantages. For this reason, the waiting periods of patients of a maxillofacial outpatient department in the various examination and treatment stations were analyzed with the help of accompanying leaflets. According to the results obtained, the sequence of examinations and treatments was verified and reorganized with regard to the three main processes: research, medical care, and education and training.

[Microwave therapy in outpatient oral surgery].

The biological action of microwave therapy is due to the conversion of high-frequency electromagnetic waves to heat that is produced directly in the tissue at the radiation area. It is a deep heating procedure of limited range with low-level exposure to the subcutaneous fatty tissue; it may be used in subacute and chronic infectious inflammatory conditions, after surgical interventions, in affections of the salivary glands and of the maxillary sinuses, and also in temporo-mandibular joint disorders and facial neuralgias. As a rule, irradiation by microwaves is only a supporting treatment.

[Comparative studies on the breaking strength of tissue adhesives of the butylcyanoacrylate type].

Four tissue adhesives of the butylcyano-acrylate type were tested for breaking strength. The addition of dyes and stabilizers results in an increase in breaking strength. Adhesives coloured with an anthraquinone dye and stabilized with SO2 significantly surpass in breaking strength adhesives that are only coloured or stabilized.
