[The use of different conscious sedation procedures in ambulatory dental surgery].

Conditions and selections of patients undergoing oral surgery under intravenous conscious sedation are reviewed. The practicability of several medicaments and combinations are discussed. Intravenous conscious sedation in combination with local anesthesia is an alternative during unpleasant surgical and dental procedures, and in several cases, can replace general anesthesia. A sufficient monitoring as well as a good trained staff makes the methods safe and allows to reduce complications.

[Combined surgical-orthodontic palatine suture expansion in adulthood].

A method of surgical support of a rapid maxillary expansion is described. Specific osteotomies are performed on the attached region of the maxillary zygomatic process and the dorsal and middle part of the hard palate. The results of 14 patients are demonstrated. Almost all patients underwent surgical correction of sagittal and/or vertical jaw relations after a subsequent harmonization. This surgical orthodontic expansion proved to be an efficient and low pain method of preoperative correction of transverse maxillary deficiencies and facilitated the following skeletal surgery.

[Frey's syndrome (gustatory sweating) after fracture of the temporomandibular joint].

Damage of the auriculo-temporal nerve with consecutive Frey's syndrome (gustatory sweating) can occur with fractures of the temporomandibular joint (TMJ) as a result of the anatomic proximity. A case of marked gustatory sweating as a rare complication of a mandibular joint fracture and alternation of therapy are reported.

[Masseter muscle flaps and buccal mucosa transposition flaps in the reconstruction of the dorsal oral cavity and the oropharynx].

The m. masseter crossover flap according to Tiwari combined with a buccal mucosa transposition flap represents an excellent technique for a primary two-layered closure of defects due to surgical removal of T2- and small T3-tumors of the posterior part of the lateral floor of the mouth, the posterior edge of the tongue, the retromolar trigone, the soft palate and the tonsilar region. Especially advantageous are the low postoperative morbidity, the low rate of postoperative complications, and good functional and cosmetic results. The surgical expenditure is little and recommends the use of this technique also in patients with reduced operability.

[Panoramic zonography in the diagnosis of TMJ fractures].

The radiological diagnosis of fractures of the mandibular condyle may be quite difficult. In a study of 237 patients the value of panoramic zonography is evaluated. Advantages of the new method are orthoradial projection, examination in a supine position, and good visibility of the anatomical structures in the TMJ-S and TMJ-PA program. Radiation doses in conventional radiography are 40-60 times higher than in panoramic zonography. High resolution CT should be reserved for special indications.

[The primary reconstruction of soft palate by intraoral buccal transposition flap].

A method for the primary reconstruction of soft palate after radical tumor excision is described. By combination of a cranial pedicled pharynx flaps and a cranial pedicled intraoral buccal transposition flap is it possible to close the resulting defect in a double layer. In additional resection of the combination of the method with a M. masseter-transposition flap is possible. By the method it is possible to have a satisfactory reconstruction of swallowing and speech functions with only small operative troubles.

[Experiences with surgically supported maxillary expansion].

The experience of a method for surgical support of a rapid maxillary expansion is described. The attached region of the maxillary zygomatic process and the dorsal and middle part of the hard palate are osteomized. The results of 18 patients are demonstrated. Almost all patients underwent surgical correction of the sagittal and/or vertical jaw discrepancies later. This surgical-orthodontic expansion proved to be an effective and low pain method for preoperative correction of transverse maxillary deficiencies and facilitated the subsequent skeletal surgery. After the treatment mentioned above in cases with a correct position of the maxilla in relation to the skull base a Le-Fort-I-Osteotomie was not necessary.

[Value of squamous cell epithelial-associated (SCC-) antigens in early diagnosis of oral carcinoma].

The diagnostic value of plasma concentration of the squamous cell carcinoma antigen was examined in 75 cases of pretherapeutic squamous cell carcinoma of the oral cavity. A pathologic plasma level was found in 32% of the tumour patients at time of diagnosis. The incidence of elevated SCC- values was inversely correlated to the tumour grading. A direct correlation of the sonographically measured total tumour volume was seen. As predominantly more extended tumours show pathologic values, SCC-Antigen is not a marker for the screening in the diagnosis of the early cancer of oral cavity. That emphasizes the importance of the precise clinical examination of each patient. In cases of elevated pretherapeutic values SCC-Antigen is very useful for therapy--monitoring and follow-up.

[Defect prosthesis following total upper jaw resection].

Using the method described, a defect prosthesis can be fastened with the help of operatively prepared retention sites and transnasal anchorage after total upper jaw resection. The technical process of manufacture is outlined and the result demonstrated in photographs.

[Diagnosis of luxation-fracture of mandibular condyle].

Based on an unusual case of bilateral mandibular condyle fracture the diagnostic problems are described. If conventional X-ray, panorama-tomograms and bilateral tomograms of both temporomandibular joints do not exactly show the fracture dislocation and the relation of the fragments CT scans should be taken.

[Sonographic diagnosis of head and neck tumors in association with therapy].

Basing on the experience with 558 patients suffering from tumours or suspicious lesions in the head and neck region, sonographic pointers that have been inadequately noted so far, are pointed out to improve diagnosis, follow-up, and post-therapeutic care. Among the possibilities offered by sonography are: to confirm or exclude bony involvement of the mandible in tumours of the oral cavity and the oropharynx, to objectify the results of antineoplastic chemotherapy, to offer possibilities to optimize radiotherapy, as well as to show criteria for the early detection of a relapse under consideration of the primary therapy.

[Realtime sonography].

Between March 1985 and March 1988 109 patients with tumours of the oral cavity and the oropharyngeal region underwent 123 examinations by orthopantomography and realtime sonography for primary staging and/or diagnosis of a recurrent disease. In 105 cases the preoperative results could be compared to intraoperative and histopathological findings. Realtime sonography as a noninvasive, inexpensive and efficient method offered the ideal diagnostic adjunct to the orthopantomogram. Not only size, shape and structure of the soft tissue tumour could be accurately defined; whatsmore it was possible to demonstrate its relation to bony structures and to a high degree of sensitivity cortical invasion and periosteal reaction. The limitations of the method especially the risk of false positive findings after invasive diagnostic and therapeutic procedures are pointed out.

[Antiphlogistic effect of bromelaine following third molar removal].

A placebo-controlled double-blind study of 100 patients with impacted and/or dislocated lower wisdom teeth was conducted to examine the tolerance and antiphlogistic efficacy of bromelaine--a mixture of proteolytic enzymes from ananas comosus. Treatment was started 1 day prior to third molar surgery with a daily dose of 3 x 80 mg and was continued for a total of 6 days. On the 1st day following surgery, linear measurement (distance: tragus-pogonion) showed swelling to be 7.5% lower under drug treatment than in the placebo group. Two-dimensional image evaluation increased this difference to 15.9%, which however still failed to attain the significance level of 20%. Between the 3rd and the 7th postoperative day no differences were found between the two groups regarding the extent of soft tissue swelling or the speed of edema resolution.
