No full textPurpose: The increasing use of vascularized free flaps has increased the demand for a specified flap selection. This study investigated histologic differences in the arterial wall of the pedicle for commonly used free flaps and the effect of age, gender, and anatomic side on these differences. Materials and Methods: Light microscopic examinations of vessel walls were performed on 245 specimens of the nourishing artery of commonly used free vascularized flaps in preserved cadavers. The peroneal artery (PA), radial artery (RA), inferior epigastric artery (IEA), deep circumflex iliac artery (DCIA), and circumflex scapular artery (CSA) were examined. Differences of histologic changes in the arterial wall and the effect of age, gender, and body side were investigated. Results: All examined vessel specimens (age range, 62 to 98 yr; mean age, 83 yr; 15 female and 12 male) displayed mostly Class II changes. PA showed the greatest atherosclerotic changes, followed by the RA, IEA, DCIA, and CSA. Age had a meaningful effect on PA and RA. Anatomic side was important for PA and DCIA, whereas gender had a minor influence on vessel condition. Conclusion: The vessel wall of different flaps showed different atherosclerotic changes depending on age, anatomic side, and gender. These differences should be considered in flap selection.

No full textIn this study, the recording of mandibular movements was tested and analyzed using four inertial measurement units. The tests were carried out with two specially manufactured sensor frames for intraoral anchoring. To obtain data, a comparative test was designed to investigate the mode of action of the Aqualizer. The results prove that the acquisition is possible and that the measurement data can be analyzed in the form of cardan angles. On the one hand, it can be hypothesized that two inertial measurement units are sufficient for motion detection and, on the other hand, that the Aqualizer can bring about significant changes in specific test subjects. However, the pilot study was unable to verify the new hypotheses due to the small number of test subject
