    Description / Table of Contents: Zusammenfassung. Die Madelung-Launois-Bensaude-Lipomatose ist eine seltene Erkrankung, die durch ausgedehnte Fettansammlungen hauptsächlich in der Halsregion charakterisiert ist. Anhand einer Fallbeschreibung werden die klinischen Besonderheiten und der Verlauf dieser Erkrankung aufgezeigt. Eine bilaterale funktionelle „neck dissection“ konnte im speziellen Fall ein erneutes Rezidiv verhindern.
    Notes: Summary. Madelung-Launois-Bensaude lipomatosis is a rare disease characterized by an enormous accumulation of fat, mainly in the region of the neck. A case is presented to illustrate the course of the disease and its clinical features. In particular, the necessity for a bilateral conservative neck dissection is emphasized to avoid early recurrence.

    Notes: Abstract  A microwave-assisted solvent extraction technique was developed for the extraction of free amino acids from foods. Four different samples were subjected to microwave extraction with varying amounts of extractant at several temperature values, for varying times to determine optimum extraction conditions. The extractions were performed with or without shaking the vessels in order to investigate the effects of mixing on the extraction efficiency and reproducibility. A comparison was made between this method and the traditional 1 h shaking extraction. The experiments indicated that the microwave-assisted extraction is an effective technique for the extraction of free amino acids from samples of plant or animal origin. The extraction yields obtained by the microwave method were about 10% better than by the conventional shaking technique. The times needed for the complete sample preparations were reduced by 66% with the application of microwaves.

    Notes: Abstract Complexes represented by the general formula [MCl2L2] (M(II)=Zn, Mn, Co) and complexes of [Cu3Cl6L4] and CuSO4L2·4H2O, CoSO4L2·3H2O, [ZnSO4L3] where L stands for 3-amino-5-methylpyrazole were prepared. The complexes were characterized by elemental analysis, FT-IR spectroscopy, thermal (TG, DTG, DSC and EGA) methods and molar conductivity measurements. Except for the Zn-complexes, the magnetic susceptibilities were also determined. Thermal decomposition of the sulphato complexes of copper(II) and cobalt(II) and the chloro complexes of cobalt(II) and manganese(II) resulted in well-defined intermediates. On the basis of the IR spectra and elemental analysis data of the intermediates a decomposition scheme is proposed.

    Description / Table of Contents: Summary The masticatory rehabilitation of patients is dependent on the quality and volume of residual jaw bone. Loss of volume caused by tumor-related mandibular ridge resection or age-related atrophies may cause considerable problems. Reconstructive methods using free iliac bone, external tabula, or sandwich plasties are only a few examples of the common surgical treatment modalities. Doing without bone grafts, alveolar ridge augmentation by means of distraction osteogenesis might become a value method to improve the denture-bearing area. A new distraction implant system is shown and its first clinical use reported. Two distraction implants were inserted after an anterior segmental osteotomy. The alveolar ridge was then elevated 1 mm each day until the required augmentation of about 8 mm was achieved. After a latency period for pre-ossification of the callus, the distraction implants were replaced by the endosseous implants. The implant system and the surgical technique are shown, and the results are discussed. We believe that the implant distraction procedure will make useful contribution to the management of masticatory rehabilitation.
    Notes: Zusammenfassung Die kaufunktionelle Rehabilitation eines Patienten ist nicht zuletzt von der Qualität und dem Volumen des vorhandenen Kieferknochens abhängig. Volumenverluste nach tumorbedingten Unterkieferkastenresektionen oder altersabhängige Atrophien können hier erhebliche Probleme bereiten. Ersatzplastiken mit freiem Beckenkamm, Tabula externa oder Sandwich-Plastiken sind nur einige Beispiele für die bislang üblichen chirurgischen Behandlungsverfahren. Unter Verzicht auf Knochentransplantate könnte die Kieferkammaugmentation mit Hilfe der Distraktionsosteogenese hier einen wertvollen Beitrag zur Verbesserung des Prothesenlagers liefern. Es werden ein neues, implantatgestütztes System zur vertikalen Knochendistraktion vorgestellt und über einen ersten klinischen Einsatz anhand einer Einzelfallbeschreibung berichtet. Nach einer anterioren Segmentosteotomie wurden 2 Distraktionsimplantate inseriert, dann der Kieferkamm täglich um 1 mm bis zur gewünschten Augmentation um 8 mm angehoben. Nach einer 4wöchigen Latenzphase zur Frühossifikation des Kallus wurden dann die Distraktionsimplantate durch definitive enossale Implantate ersetzt. Insgesamt hat uns die klinische Anwendung ermutigt, den hier begonnenen Weg fortzusetzen. Implantatsystem und Operationstechnik werden erläutert, die Ergebnisse diskutiert.

    Description / Table of Contents: The pre- and postoperative symptoms of zygomatic bone fractures were examined in a follow-up study to prepare a classification proposal. A differential indication for minimally invasive therapy modes was looked for with respect to this proposal. Therapy of isolated zygomatic bone fractures consisted in repositioning with a hook and miniplate fixation across the frontozygomatic suture. The aims of this study were clinical and radiological assessment of the repositioning result in terms of aesthetics and stability and quantification of the postoperative remission of disturbances of sensitivity of the infraorbital nerve. A total of 52 patients were examined. After the operation (on average after 3.5 days following the trauma) they were followed-up postoperatively for 12 months according to a strict schedule. Preoperatively, 49 patients reported disturbances of sensitivity of the infraorbital nerve. Other symptoms, such as periorbital haematoma and flattening of the zygomatic prominence, were observed in 49 patients and 45 patients, respectively. All fractures were repositioned well as assessed clinically and radiologically. The aesthetic result was evaluated as symmetric and durable in all cases. Six months postoperatively 41 patients reported normal sensitivity in the area of the infraorbital nerve. In only five patients (10.2%) was the sensitivity loss persistent throughout the entire follow-up period. Patients with primarily lacking diplopia developed neither eye motility disturbances nor postoperative enophthalmus in the following period. It can be concluded that the treatment of an isolated zygomatic bone fracture which satisfies aesthetic and functional requirements is possible by reposition and fixation with one miniplate at the lateral orbital rim. An additional osteosynthesis at the infraorbital rim or at the zygomaticomaxillary crista is not necessary. A routine revision of the orbital floor is only indicated in cases of preoperative diplopia. A zygomatic bone fracture connected with diplopia should be classified as combined zygomatic-/orbital floor fracture.
    Notes: In einer Follow-up-Studie wurden die prä- und postoperativen Symptome von Jochbeinfrakturen zur Erstellung eines Klassifikationsvorschlags bestimmt und eine Differentialindikation für einen möglichst wenig invasiven Therapiemodus aufgrund dieses Vorschlags gesucht. Der Therapiemodus bei isolierten Jochbeinfrakturen bestand aus einer Hakenreposition und der Fixation mit einer Miniplatte am zygomatikofrontalen Übergang. Ziele der Studie waren die klinische und radiologische Überprüfung des Erfolgs dieses Therapiemodus im Hinblick auf die Ästhetik, Stabilität und Gesichtskontur sowie die postoperative Remission der bei einer Jochbeinfraktur auftretenden Sensibilitätsstörungen des N. infraorbitalis bei diesem Therapiemodus. Erfaßt wurden 52 Patienten. Nach der Operation (im Mittel 3,5 Tage nach dem Trauma) wurden sie nach einem festen Schema bis zu 12 Monaten postoperativ nachkontrolliert. Präoperativ gaben 49 Patienten Sensibilitätsstörungen des N. infraorbitalis an. Andere Symptome wie Monokelhämatom und Abflachung der Jochbeinprominenz wurden in dieser Reihenfolge bei 49 Patienten bzw. bei 45 Patienten beobachtet. Das Repositionsergebnis war in allen Fällen sowohl klinisch als auch radiologisch zufriedenstellend und blieb auch dauerhaft bis zur letzten Nachuntersuchung nach 12 Monaten erhalten. Nach 6 Monaten hatten 41 Patienten keine Sensibilitätsstörung mehr. Lediglich 5 Patienten (10,2%) behielten eine über den Nachbeobachtungszeitraum andauernde Sensibilitätsstörung. Patienten mit primär fehlender Diplopie entwickelten auch in der Folgezeit keine Augenmotilitätsstörung noch kam es zu einem postoperativen Enophthalmus. Es kann geschlußfolgert werden, daß zu einer ästhetisch und funktionell suffizienten Versorgung einer isolierten Jochbeinfraktur die Reposition und deren Fixation mit einer Miniplatte über einen lateroorbitalen Zugang ausreichen. Eine zusätzliche Osteosynthese infraorbital oder im Bereich der Crista zygomaticoalveolaris ist nicht erforderlich. Eine routinemäßige Orbitabodenrevision ist nur bei einer präoperativ bestehenden Diplopie zwingend indiziert. Eine mit Diplopie vergesellschaftete Jochbeinfraktur sollte daher als kombinierte Jochbein-/Orbitabodenfraktur bezeichnet werden.
