[Combined masseter and buccal mucosa transposition flap. Primary reconstruction of posterior oral cavity].

A method for the primary reconstruction of the posterior oral cavity following T2 and small T3 tumor surgery is described. The combination of a masseter flap with a cranially pedicled intraoral buccal transposition flap results in a double layer for the repair of defects. Because of its simplicity and hence a shorter operation time, this functionally satisfactory reconstructive procedure should be used particularly for high-risk patients.

[The significance of zonography in X-ray diagnosis of midfacial fractures].

The possibilities offered by panoramic zonography (MT program) in the diagnosis of the midface are outlined. The imaging quality of various anatomical structures is demonstrated both on the anatomical model and in clinical use. The benefits and limitations of this procedure are discussed. Zonography is a reliable instrument adding to the range of basic diagnostic procedures in the midfacial region.

[PVP granuloma--a complication in the treatment of facial neuralgia].

A 61-year-old female patient suffering from neuralgiform facial pain developed a PVP granuloma, after she had received peripheral conduction anesthesia treatment with a local anesthetic containing polyvinylpyrrolidone over many years. The clinical symptoms and treatment of this pseudotumor as well as the features distinguishing it from real tumors, particularly chordomas, are indicated.

[Clinical features and treatment of osteogenic sarcoma of the jaws].

24 patients with osteogenic sarcomas of the jaws were entered in a retrospective study. 79.2% of the cases had local relapses or distant metastases, usually within the first 2 years following surgery. With primary surgical treatment the 5 year disease free survival rates in cases with maxillary manifestations ranged at 22.1% and with mandibular sarcomas at 18.2%. Thus, prognosis for osteogenic sarcomas of the jaws is to be assessed as being no more favorable than for sarcomas of the extremities. A review of the literature shows that aggressive pro- and postoperative chemotherapy must be postulated apart from radical tumor resection to improve the survival rates.

[The diagnostic value of the tumor markers CEA, "Ca 19-9", "Ca 125", "Ca15-3" and "SCC" for the detection of recurrent tumors in patients with tumors of the head and neck].

An increased squamous cell carcinoma antigen (SCC) value was found in 33.3% of the patients with carcinomas of the oral cavity. In those patients in whom the tumor recurred, this percentage increased to 75%. Although elevated in 43.4% of the tumor patients, CEA values failed to drop after treatment like the SCC antigens did. Nor was there, in contrast to the SCC antigens, any evident correlation with tumor volume. Thus, pathologic CEA values must be attributed to non-tumor specific concomitant diseases. Ca 19-9, Ca 125 and Ca 15-3 exhibited poor sensitivity. According to the results of our studies the only valid tumor markers are SCC antigens, particularly for monitoring treatment.

[Autologous blood and plasma replacement in displacement osteotomies of the maxillofacial region].

The concept of autologous transfusion in displacement osteotomies in oral and maxillofacial surgery is presented. Considerately and specifically applied, autotransfusion is the safest mode of blood transfusion and may replace homologous transfusion in a planned operation involving a high amount of blood loss. Although autotransfusion requires considerably more organization and man hours, costs may be saved by avoiding the wide range of complications associated with homologous transfusions. Yet, homologous transfusion, that has its justified value particularly in emergency procedures, will never be fully replaced by autotransfusion.
