Background: After the resection at the mandibular site involving oral cancer, free vascularized fibular graft, a type of vascularized autograft, is often used for the mandibular reconstruction. Titanium mesh (T-mesh) and particulate cancellous bone and marrow (PCBM), however, a type of non-vascularized autograft, can also be used for the reconstruction. With the T-mesh applied even in the chin and angle areas, an aesthetic contour with adequate strength and stable fixation can be achieved, and the pores of the mesh will allow the rapid revascularization of the bone graft site...

Background: The management of breath-induced tumor motion is a major challenge for lung stereotactic body radiation therapy (SBRT). Three techniques are currently available for these treatments: tracking (T), gating (G) and free-breathing (FB). Aim: To evaluate the dosimetric differences between these three treatment techniques for lung SBRT. Materials and methods: Pretreatment 4DCT data were acquired for 10 patients and sorted into 10 phases of a breathing cycle, such as 0% and 50% phases defined respectively as the inhalation and exhalation maximum...

One of the leading causes of morbidity and mortality in patients with heart failure is right ventricular (RV) dysfunction, especially if it is due to pulmonary hypertension. For a better understanding and treatment of this disease, precise hemodynamic monitoring of left and right ventricular parameters is important. For this reason, it is essential to establish experimental pig models of cardiac hemodynamics and measurements for research purpose. This article shows the induction of ARDS by using oleic acid (OA) and consequent right ventricular dysfunction, as well as the instrumentation of the pigs and the data acquisition process that is needed to assess hemodynamic parameters...

BACKGROUND: Esthetic reduction malarplasty is popular in East Asia, where a small and balanced facial profile is considered a desirable characteristic. Various surgical techniques have been applied; however, several complications can impact the bony structure and final esthetic appearance. We examined the outcomes of revision malarplasty with regard to strategic assessments to achieve facial balance and skeletal stability. METHODS: This retrospective study reviewed 97 patients who underwent revision malarplasty between December 2014 and November 2016...

BACKGROUND: It has been two centuries since Petrus Camper identified superficial fascia and over 175 years since Sir Astley Cooper wrote his book on the anatomy of the breast. In the 1990s, Ted Lockwood taught us the importance of the superficial fascia layers in body contouring procedures he pioneered. These descriptions, however, fail to explain the three-dimensional fascial system in the breast. The authors set out to discover and describe a theory of superficial fascia structures responsible for breast shape...

YiJun Xia, Jun Zhao, Dong Sheng Cao
BACKGROUND: Lipoabdominoplasty is a powerful operation to maintain a youthful physique for aging people, improve body contouring, and remove excess skin caused by massive weight loss. Nonetheless, it is controversial to combine abdominoplasty and liposuction because of the potential for vascular damage of the abdominal flap and increased complications. The purpose of this article was to determine the complication rates of lipoabdominoplasty compared with traditional abdominoplasty. METHODS: PubMed, EMBASE, and Cochrane databases were searched through July of 2018...

PURPOSE: The goal of this work was to design a realistic mouse phantom as a useful tool for accurate dosimetry in radiobiology experiments. METHODS: A subcutaneous tumor-bearing mouse was scanned in a microCT scanner, its organs manually segmented and contoured. The resulting geometries were converted into a stereolithographic file format (STL) and sent to a multi-material 3D printer. The phantom was split into two parts to allow for lung excavation and 3D-printed with an acrylic-like material and consisted of the main body (mass density ρ=1...

The world is flat when it comes to aesthetic treatments, meaning women and men from all walks of life, regardless of culture and ethnicity or even socioeconomic status, are seeking ways to improve their appearance, prevent aging, and rejuvenate their skin. Year after year, statistics show a steady increase in people of color undergoing aesthetic treatments, with neurotoxins, fillers, laser resurfacing, and body contouring being the most sought-after procedures. When treating this cohort of patients, however, dermatologists need to be sensitized to how a patient's ethnicity affects facial structure, the tissue reaction to treatments, and patient's specific expectations for recommended therapies...

Radiation therapy (RT) is an effective treatment modality for hepatocellular carcinoma (HCC), but globally, it is underutilized. In Russia, practice patterns with regard to liver-directed radiation are unknown. Under the auspices of Russian Society of Clinical Oncology (RUSSCO), our team conducted an IRB-approved contouring workshop for Russian radiation oncologists. Pre- and post-workshop surveys were analyzed to determine baseline clinical experience and patterns of care for liver-directed RT among Russian providers...

Standards assume vibration discomfort depends on the frequency and direction of whole-body vibration, with the same weightings for frequency and direction at all magnitudes. This study determined equivalent comfort contours from 1.0 to 10 Hz in each of three directions (fore-and-aft, lateral, vertical) at magnitudes in the range 0.1 to 3.5 ms-2  r.m.s. Twenty-four subjects sat on a rigid flat seat with and without a beanbag, altering the pressure distribution on the seat but not the transmission of vibration...

PURPOSE: Wide bore CT scanners use extended field-of-view (FOV) reconstruction algorithms to attempt to recreate tissue truncated due to large patient habitus. Radiation therapy planning systems rely on accurate CT numbers in order to correctly plan and calculate radiation dose. This study looks at the impact of extended FOV reconstructions on CT numbers and radiation dose calculations in real patient geometries. METHODS: A large modular phantom based on real patient geometries was created to surround a CIRS Model 062M phantom...

REVIEW
Joseph Michaels
Excess thigh laxity is a problem for many patients following significant weight loss. Thigh laxity has both vertical and horizontal components that require correction to optimize the aesthetic appearance of the thigh. The vertical vector is best corrected first with a lower body lift or extended abdominoplasty. The remaining loose skin in the medial thigh can then be removed using a horizontal vector resulting in a vertical incision. Residual vertical skin excess is also removed parallel to the groin crease...

REVIEW
Flávio Henrique Mendes, Alfredo Donnabella, Alan Roberto Fagotti Moreira
Body contouring for patients with massive weight loss may demand not only lifting but also some extent of central body tightening to achieve complete tissue readjustment. Although the fleur-de-lis procedure usually achieves nice contouring results, poor visible scars, including umbilical complications, have restricted the indications for the anterior vertical approach. The purpose of this article is to present the authors' experience with the inner scar umbilical reconstruction, enhancing overall results for vertical abdominoplasties...
