Intraoral cheek transposition flap for primary reconstruction of the soft palate.

A method for primary reconstruction of the soft palate following radical tumor resection is described. The resulting defects can be repaired with 2 layers of tissue by combination of a cranial pedicled pharyngeal flap and a cranial pedicled intraoral cheek transposition (IOCT-) flap. For additional resection of the lateral pharyngeal wall the technique can be combined with a masseter crossover flap. The method allows satisfying restoration of swallowing and speech with relatively small operative effort.

The combined masseter muscle/intraoral cheek transposition (IOCT) flap for primary reconstruction of the dorsal oral cavity.

A method for primary reconstruction of the dorsal oral cavity after tumor resection of T2 or small T3 tumors is presented. By combination of the masseter muscle flap with a cranial pedicled intraoral cheek transposition (IOCT) flap, a reconstruction of the defects with two layers of tissue is possible. This easy and functional reconstruction method is especially useful for high-risk patients because of the markedly reduced operating time.

[The value of "tumor markers" in the therapy and aftercare of carcinoma of the oral mucosa].

Biochemical Markers (alpha-1-acid glycoprotein, ferritin, transferrin) and tumor associated markers (TPA, CEA, SCC-antigen) are described. Concerning the screening of oral carcinoma, the use of tumor markers is to be considered with criticism. The SCC-antigen seems to be the most useful for detection of recurrence in the follow-up. But no tumor marker can replace exact physical and ultrasound examinations.

[Combination of velopharyngoplasty and transposition flap of buccal mucosa for primary reconstruction of the soft palate].

Reconstruction of the soft palate after tumor surgery can present a challenge in closing the defect created and achieving a sufficient functional result. We present a new technique for primary reconstruction after partial or total resections of the soft palate. The method is based on the combination of a cranially pedicled pharyngeal mucosa muscle flap with an oral mucosal transposition flap. If partial resection of the lateral pharyngeal wall is also required, the method can be combined with a masseter crossover flap. Our present experience has shown that the surgical technique used will result in an uncomplicated and rapid primary two-layer reconstruction of the soft palate with a comparatively low postoperative complication rate and satisfactory functional results in speaking and swallowing.

[Sonography in therapy-oriented diagnosis and after-care of primary bone and soft tissue tumors].

Based on the results of 150 patients with primary tumors or the suspicion of malignant lesions of the locomotor system the perspectives and limits of the sonographic diagnosis under the therapeutic aspects of interdisciplinary oncologic cooperation is demonstrated. As the ideal adjunct to conventional roentgenograms, ultrasound is the first-line imaging procedure in the fields of primary diagnosis, follow-up, post-therapeutic care as well as tumor exclusion for methodic, patient-related and economic/logistic reasons. Its consequent application will markedly reduce the number of more invasive and expensive methods.

[Comparison of two methods for conscious sedation in maxillofacial surgery with local anesthesia].

A randomised, prospective study was conducted to compare the efficiency and safety of methods for intravenous conscious sedation in patients undergoing oral surgery under local analgesia. 150 systemically healthy patients (ASA Class I and II) participated. Three groups were formed: group 1 received 0.05 mg/kg midazolam; group 2 0.05 mg/kg midazolam, 1.5 mg/kg tramadol, 50 mg alizaprid; group 3 0.05 mg/kg midazolam, 0.2 mg/kg nalbuphine, 50 mg alizaprid. Blood pressure, heart rate and oxygen saturation were measured throughout the procedure. The results confirmed that the use of nalbuphine (group 3) allows a reduction in the mean dosage of midazolam required to produce satisfactory sedation and effected a more rapid recovery time compared to group 12 and 2. With the combination nalbuphine and alizaprid nausea and vomiting could be reduced for the most part compared to group 2.

[Septic granulomatosis (chronic granulomatous disease = CGD) in the jaw area. A case report].

A rare case of chronic granulomatous disease with manifestation in the mandible is presented. A 10-year-old boy showed the clinical picture of osteomyelitis without paresthesia (Vincent syndrome). Diagnosis was done by the nitroblue tetrazolium test (NBT) and by demonstration of a complete cytochrome-b deficiency of the granulocytes. In septic granulomatosis a continuous application of Sulfamethoxazol-Trimetoprim is recommended for prophylaxis of infection. For treatment of infection further antibiotics who pass into the granulocytes like rifampicin and fosfomycin are necessary. Oral surgical procedures request a careful tissue handling and a tight wound closure.

[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.
