One of the most impressive soft tissue injuries is the facial degloving, normally associated with industrial machines and traffic accidents. This injury is characterized by the separation of the skin and cartilage from the bones, compromising the soft tissues correlated in the trauma area, nerves, and blood vessels. A 28-year-old patient, male, was referred to Araçatuba's Santa Casa Hospital, after a motorcycle accident, hitting his face on the sidewalk. The patient was conscious, oriented, denying fainting and unconsciousness during the accident, and complaining of pain in the nasal region of the face...

: Reconstruction after mastectomy is an important milestone for many women treated for breast cancer. However, because many surgeons only offer their preferred method of reconstruction, it is not clear which approach women would choose if offered a genuine choice. METHODS: Between 1998 and 2010, the breast reconstruction service at a major Australian teaching hospital was staffed by a single plastic surgeon trained in both prosthetic and autologous breast reconstruction techniques...

Environmental DNA (eDNA), genetic material recovered from an environmental medium such as soil, water, or feces, reflects the membership of the ecological community present in the sampled environment. As such, eDNA is a potentially rich source of data for basic ecology, conservation, and management, because it offers the prospect of quantitatively reconstructing whole ecological communities from easily obtained samples. However, like all sampling methods, eDNA sequencing is subject to methodological limitations that can generate biased descriptions of ecological communities...

Microcystic adnexal carcinoma (MAC) is a rare malignant cutaneous adenocarcinoma that typically occurs in the head and neck, particularly at the central face. There are only slightly more than 300 patients reported worldwide, and most patients occur in Caucasians. A 72-year-old man was referred to our hospital for definitive treatment of known MAC from previous biopsy. Wide excision of nasal tip and reconstruction of nasal defect with paramedian forehead flap and nasolabial flap transposition were performed rather than conventional Mohs surgery, due to grossly evident disease...

PURPOSE: To hypothesize a new theory based on soft tissue reference points on lateral profile photographs (LPPs) for determining the vertical dimension of occlusion (VDO), as there is need to explore for simple strategies. MATERIALS AND METHODS: Fifty-three participants in the age range of 20-27 years who met the inclusion criteria were recruited. LPPs were taken for all participants using standard protocol and duplicate copies obtained, on which five soft tissue reference points, nasion (Stn), subnasale (Stsn), porion (Stp), gnathion (Stgn), and gonion (Stg) (Stg prenoted on the face) were marked and joined to form angles; distance between Stsn and Stgn was considered as VDO in LPP (VDO-LP)...

BACKGROUND: The anterior chest is an excellent donor site for cervicofacial reconstruction. Studies of chest flaps began as early as 1988 at our institution. We identified a new branch of the supraclavicular artery that nourishes the anterior chest, and on the basis of this finding, we created a new flap called the subclavicular flap. Unlike the supraclavicular flap, which is pedicled by the deltoid branch, this flap is primarily pedicled by the thoracic branch, and it shares similar vascular territory with the deltopectoral flap...

OBJECTIVE: To define the radiographic origin and insertion of the canine medial glenohumeral ligament (MGHL) at the scapula and the humerus of dogs as radiographic aim points for the surgical ligament reconstruction. MATERIAL AND METHODS: The forelimbs (n = 20) from 10 adult, orthopaedically unaffected dogs (> 20 kg body weight) were used. Radiopaque markers (1 mm steel bullet) were placed into the visual origin and insertion of the MGHL. Finally, virtual digital radiographs were produced in medio-lateral and cranio-caudal projection and the location of the origin and insertion points were expressed using four different methods (4x4 grid box method, percentage position in the grid box for the medio-lateral projection, the percentage position orientated at different landmarks and the clock-face scale method)...

As always, the clinical therapy of critical size bone defects caused by trauma, tumor removal surgery or congenital malformation is facing great challenges. Currently, various approaches including autograft, allograft and cell-biomaterial composite based tissue-engineering strategies have been implemented to reconstruct injured bone. However, due to damage during the transplantation processes or design negligence of the bionic scaffolds, these methods expose vulnerabilities without the assistance of periosteum, a bilayer membrane on the outer surface of the bone...

BACKGROUND: Facial self-inflicted gunshot wounds (SIGSWs) cause a devastating midfacial defect and pose a challenging problem to the reconstructive surgeon. Face transplantation (FT) has the potential for near-normal restoration in otherwise non-reconstructible defects. Two out of 7 FT recipients at Brigham and Women's Hospital (BWH) sustained SIGSWs. In this study, we illustrate the role of FT in the management of SIGSWs through an aesthetic, functional, and psychosocial examination of outcomes...

BACKGROUND: Research evidence shows that healthcare professionals do not fully comprehend the difficulty involved in problems faced by people living with severe mental illness (SMI). As a result, mental health service consumers do not show confidence in the healthcare system and healthcare professionals, a problem related to the phenomenon of adherence to therapy. Moreover, the issue of unmet needs in treating individuals living with SMI is relared to their quality of life in a negative way...

Management of mutilating hand injury is a challenge for any hand surgeon. Delay in presentation makes management even more challenging, usually because of inadequate initial assessment, inadequate debridement leading to infection, and secondary loss of tissues from exposure and desiccation. The aim is to obtain a functional hand by radical debridement, adequate assessment of the injury, appropriately timed reconstruction, and physiotherapy and rehabilitation. The hand surgeon must pay attention to the appearance of the hand by elimination of deformities, unsightly scars and bulky flaps to help to restore confidence in the patient to face the demands of daily living...

Surgeons managing mutilating hand injures are faced with difficult decisions between attempting to salvage remaining or injured digits or proceeding to amputation and fusion. Through application of a basic understanding of hand biomechanics, the surgeon may more accurately predict what motion and function can best be salvaged. This article provides an explanation of how amputation, fusion, and tendon loss can affect postoperative hand motion. The surgeon can use these concepts in planning the reconstruction or preparing the foundation for secondary reconstructive procedures to achieve the highest functional outcome for the patient...

The preoperative assessment of anterior glenoid bone loss is a critical step in surgical planning for patients with recurrent anterior glenohumeral instability. The structural integrity of the glenoid has been identified as one of the most important factors influencing the success of operative repair. The currently accepted gold standard for glenoid structural assessment among most orthopaedic surgeons is the use of 3-dimensional reconstructed computed tomography images with the humeral head digitally subtracted, yielding an en face sagittal oblique view of the glenoid...

Many important biological questions can be addressed by studying in 3D large volumes of intact, cryo fixed hydrated tissues (⩾10,000μm(3)) at high resolution (5-20nm). This can be achieved using serial FIB milling and block face surface imaging under cryo conditions. Here we demonstrate the unique potential of the cryo-FIB-SEM approach using two extensively studied model systems; sea urchin embryos and the tail fin of zebrafish larvae. We focus in particular on the environment of mineral deposition sites...

BACKGROUND: Face transplantation has emerged as a viable option for certain patients in the treatment of devastating facial injuries. However, as with autologous free tissue transfer, the need for secondary revisions in face transplantation also exists. The authors' group has quantified the number of revision operations in their cohort and has assessed the rationale, safety, and outcomes of posttransplantation revisions. METHODS: A retrospective analysis of prospectively collected data of the authors' seven face transplants was performed from April of 2009 to July of 2015...
