In mandibular reconstructive surgery, straight surgical plates are predominantly used for osteotomy. In this process, a straight plate is bent to fit to the shape of the patient's defect. This potentially compromises the stability of the plate because of changes in mechanical properties resulting from plastic deformation; however, the effect of plastic deformation on stability has yet been investigated. In this study, we assess the stability of three types of commonly used bent plates for two types of mandible defect cases, using three-dimensional finite element analysis (FEA)...

To determine if facial plastic and reconstructive surgeons still adhere to the classic nasal subunit principle as described by Burget and Menick. Observational survey. A Weill Cornell Medicine institutional review board approved electronic survey that was sent via e-mail to active members of the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS). The survey consisted of 32 multiple-choice questions pertaining to the operative management of small (22-30%), medium (50-58%), and large (75-81%) defects of each subunit of the nose, as well as demographic, provider, and practice characteristics...

OBJECTIVE: This study investigates the hypoperfusion effects of epinephrine in local anesthesia in eyelid surgery. A novel form of extended-wavelength diffuse reflectance spectroscopy was evaluated. METHODS: Blood perfusion in porcine eyelid flaps was measured using laser Doppler velocimetry and laser speckle contrast imaging, whereas the tissue response was measured using diffuse reflectance spectroscopy with a broad spectrum (450-1550 nm). Epinephrine was either injected cumulatively, 0...

The goals of sarcoma management include both a cure and the functional preservation of involved tissues and adjacent critical structures with common opinions favoring immediate reconstruction. The question arises whether these goals are contradictory. This paper discusses the question based on the experience of 28 patients with different types of extremity sarcoma, with 24 surgically treated by the University of California San Diego (UCSD) orthopedic and plastic surgery team (2011-2016) and the collection of evidence from published practice guidelines, reviews, case studies, and clinical trials...

BACKGROUND: Early reconstruction after mastectomy for breast cancer with definitive implants has been widely used, especially with the evolution of conservative surgical breast cancer treatments. We aimed to identify different characteristics associated with plastic surgery, based on immediate or delayed reconstruction time and evaluate quality of life in patients undergoing mastectomy for cancer. METHODS: This is a cross-sectional analytical study that evaluated adult patients undergoing mastectomy for breast cancer and breast reconstruction in Plastic Surgery Service at a tertiary hospital...

Basal cell carcinoma (BCC) is the most common cutaneous cancer. Although most cases can be cured with simple surgical procedures and are associated with a good prognosis, a minority of BCCs may pose significant therapeutic challenges. This occurs mostly in cases of so-called advanced BCC, which a loosely defined term that encompasses locally advanced lesions and tumors with metastatic spread. Treatment of these cases is often complex and sometimes may need combinations of therapeutic modalities, including surgery, radiotherapy and/or targeted therapy directed towards sonic hedgehog (SHH) signaling pathways, such as vismodegib...

Random skin flaps are commonly used in plastic and reconstructive surgery for patients suffering from severe or large scale wounds or in facial reconstruction. However, skin flaps are sometimes susceptible to partial or complete necrosis at the distal parts of the flaps due to insufficient blood perfusion in the defected area. In order to improve neovascularization in skin flaps, we developed an exogenous growth factor (GF) delivery platform comprised of coacervate-coated poly(lactic-co-glycolic acid) (PLGA) nanofibers...

INTRODUCTION: Despite a national health care policy requiring payers to cover breast reconstruction, rates of postmastectomy reconstruction are low, particularly among minority populations. We conducted this study to determine if geographic access to a plastic surgeon impacts breast reconstruction rates. METHODS: Using 2010 inpatient and ambulatory surgery data from 10 states, we identified adult women who underwent mastectomy for breast cancer. Data were aggregated to the health service area (HSA) level and hierarchical generalized linear models were used to risk-standardize breast reconstruction rates (RSRR) across HSAs...

Two-dimensional photographs are the standard for assessing craniofacial surgery clinical outcomes despite lacking three-dimensional (3D) depth and shape. Therefore, 3D scanners have been gaining popularity in various fields of plastic and reconstructive surgery, including craniomaxillofacial surgery. Head shapes of eight adult volunteers were acquired using four 3D scanners: 1.5T Avanto MRI, Siemens; 3dMDface System, 3dMD Inc.; M4D Scan, Rodin4D; and Structure Sensor, Occipital Inc. Accuracy was evaluated as percentage of data within a range of 2 mm from the 3DMDface System reconstruction, by surface-to-surface root mean square (RMS) distances, and with facial distance maps...

: 33 Background: Processing operative instrumemt sets is a major cost for surgical cancer care. Optimizing standard sets requires availability of instruments reflecting varied surgeon preferences while minimizing unnecessary instruments. Additionally, increasing utilization of oncoplastic reconstruction after mastectomy and lumpectomy requiring breast and plastic surgery sets further expands the number of instruments required. The goal of our study was to optimize standard sets used for cases combining breast and plastic surgeons and to determine cost savings Methods: Baseline data was recorded over a 2 week period (13 cases) including number of instruments available and number unused for non- flap breast-plastics combo (BPC) cases...

The aim of this article is to document the experience of the author who volunteered as a resident for 6 months at a districtlevel hospital in central Kenya. Peculiarities emerging from the report are: specificity of the experience to plastic reconstructive surgery; highly complex reconstructive procedures performed under direct supervision of a qualified mentor; exposure to diverse approaches through collaboration with different volunteer plastic surgeons; enhancement of long-term surveillance; and opportunity to expand surgical knowledge outside one's field of specialty...

AIM: To evaluate the results of the Ilizarov method in management of cases with bone loss, soft tissue loss and infection. METHODS: Twenty eight patients with severe leg trauma complicated by bone loss, soft tissue loss and infection were managed by distraction osteogenesis in our institution. After radical debridement of all the infected and dead tissues the Ilizarov frame was applied, corticotomy was done and bone transport started. The wounds were left open to drain...

: The aim of the study was to present our experience with the postauricular island flap (pif) and clinical evaluation of the results following auricular conchal bowl reconstructions with the pif in patients after carcinoma resections. MATERIAL AND METHODS: We analyzed results in 13 patients who underwent auricular conchal bowl reconstructions with pif following malignant tumor resection between 2000-2013. The patients were followed-up. We estimated early and long-term results after surgery including plastic surgeon's and patient's opinion...

Superficial temporal artery (STA) based pedicled fascial flap plays a pivotal role in ear reconstruction for microtia patients. There is paucity of literature on the anatomy of the STA in microtia patients. The present study aimed to describe any possible anatomical variations seen in the STA of patients afflicted with microtia. Pre-operative carotid computer tomographic angiography images of patients under the microtia database of Plastic and Reconstructive Surgery Unit at a tertiary medical centre were selected and 3-dimensionally reconstructed...

BACKGROUND: Despite research supporting improved psychosocial well-being, quality of life, and survival for patients undergoing postmastectomy breast reconstruction, Asian patients remain one-fifth as likely as Caucasians to choose reconstruction. This study investigates cultural factors, values, and perceptions held by Asian women that might impact breast reconstruction rates. METHODS: The authors conducted semistructured interviews of immigrant East Asian women treated for breast cancer in the New York metropolitan area, investigating social structure, culture, attitudes toward surgery, and body image...
