In craniofacial surgery, a wide spectrum of pathological conditions are usually treated. The aetiology of these could be congenital, traumatic, infective, post-tumor resection, postradiation, autoimmune, iatrogenic, or other miscellaneous conditions. The surgical approach for the procedures is usually via a coronal incision. In a large proportion of the patients, the frontal bone is removed to obtain intracranial access. The frontal bone is then replaced either in its original form or in a remodeled state. In congenital conditions the supraorbital bar and frontal bone is often also removed, remodeled, and replaced...

PURPOSE: To determine if arthroscopic partial trapeziectomy (APT) and soft tissue interposition arthroplasty is an effective treatment for symptomatic trapeziometacarpal arthritis. METHODS: We retrospectively evaluated 30 consecutive patients with symptomatic isolated trapeziometacarpal arthritis, Eaton-Littler stages II and III. Treatment consisted of an APT with soft tissue interposition utilizing an acellular dermal matrix as the interposition material. At a minimum of 6 months and 5 years after surgery, Numeric Pain Rating Scale (NPRS), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), grip strength, oppositional and appositional pinch strengths, arthroplasty space, and thumb range of motion (ROM) were evaluated...

BACKGROUND: Asian noses are relatively small and flat compared to Caucasians; therefore, rhinoplasty procedures often focus on dorsal augmentation and tip projection rather than reduction in the nasal framework. Various autologous and alloplastic implant materials have been used for dorsal augmentation. Recently, human acellular dermal matrices have been introduced as an implant material for dorsal augmentation, camouflaging autologous implants without an additional donor site. Here, we introduce a cross-linked human acellular dermal matrix as an implant material in augmentation rhinoplasty and share the clinical experiences...

Background: One-stage direct-to-implant immediate breast reconstruction (IBR) is performed simultaneously with breast cancer resection. We explored indications, techniques, and outcomes of IBR to determine its feasibility, safety, and effectiveness. Material and Methods: We reviewed the available literature on one-stage direct-to-implant IBR, with or without acellular dermal matrix (ADM), synthetic mesh, or autologous fat grafting. We analyzed the indications, preoperative work-up, surgical technique, postoperative care, outcomes, and complications...

The authors document their experience in the use of synthetic 100% bioresorbable surgical mesh (TIGR Matrix, Novus Scientific, Uppsala, Sweden) in breast reconstruction as well as in breast aesthetic surgery. They performed a retrospective review on patients who underwent implant-based breast reconstruction as well as patients who underwent breast reduction mammoplasty procedures with the use of TIGR Matrix Surgical Mesh. When compared with other synthetic but nonresorbable meshes, it appears to show a potentially lower seroma and infection rates, but most importantly, a lower rate of revisional and mesh explantation surgeries...

REVIEW
Amy S Colwell, Joani M Christensen
Breast reconstruction following mastectomy has evolved to preserve the native skin and nipple of the breast and create a natural-appearing reconstruction in 1 or 2 surgeries. Nipple-sparing procedures appear to be oncologically safe with low risks of cancer recurrence. In our series of 2,182 nipple-sparing mastectomies, there was no development or recurrence of cancer in the nipple. Direct-to-implant single-stage surgery offers the patient a complete reconstruction at the time of mastectomy. Patient selection centers on preoperative breast anatomy combined with postoperative goals for size and uplift of the breast...

REVIEW
John Y S Kim, Alexei S Mlodinow
Of the nearly 90,000 implant-based breast reconstructions performed in the United States, the majority use internal soft-tissue support. Aesthetically, these constructs may allow for better positioning of prosthesis, improve lower pole expansion, and increase projection. They may have particular utility in direct-to-implant, nipple-sparing mastectomies, and prepectoral reconstructions. In recent years, new permutations of acellular dermal matrices have evolved with diverse shapes, sizes, form-factor innovations, and processing characteristics...

Management of failed rotator cuff repair may be difficult, especially in young patients. Various nonmodifiable and modifiable patient factors, including age, tendon quality, rotator cuff tear characteristics, acute or chronic rotator cuff tear, bone quality, tobacco use, and medications, affect rotator cuff repair healing. Surgical variables, such as the technique, timing, tension on the repair, the biomechanical construct, and fixation, as well as the postoperative rehabilitation strategy also affect rotator cuff repair healing...

BACKGROUND: Thoracodorsal artery perforator (TDAP) flap is one of the relatively new techniques in breast reconstruction. This pedicled flap retains the benefits of perforator flaps as regards minimal donor site morbidity without the need for microvascular anastomosis. Its role in partial breast reconstruction has been well documented. However, there are few reports about the role of this flap in total breast reconstruction. METHODS: This study included 47 cases who presented to the breast unit of the National Cancer Institute of Cairo University from 2013 to 2015...

OBJECTIVE: As compression treatment offers moderate improvement, especially to recurrent venous leg ulcers (VLUs), several alternative therapies using cellular based and/or tissue-derived products (CTPs) have emerged from bovine, porcine, and equine sources. Our aim was to look at the effect of a CTP in 'real-life' VLUs. METHODS: This study looked at complex patients with chronic, large wounds in a single-centre retrospective review. All patients were treated with fetal bovine acellular dermal matrix (FBADM) for VLUs at our outpatient urban wound care programme...

Eun Soo Park, Jun Ho Park, Ho Seong Shin, Seung Min Nam
Aplasia cutis congenita (ACC), also called cutis aplasia, is a rare congenital abnormality characterized by focal defect of the skin at birth, frequently involving the scalp, but may affect any region of the body. Approximately 80% of patients have the defect confined to the skin and generally less than 2 cm diameter, which can be managed conservatively with dressing alone. However, some patients present large cutaneous defects and aplasia of the underlying skull may also be present. The main complications of large defects include meningeal infection, bleeding, and thrombosis, which may be deadly...

BACKGROUND: The success of rotator cuff repair is primarily dependent on tendon-bone healing. Failure is common because weak scar tissue replaces the native enthesis, rendering it prone to reruptures. A demineralized bone matrix (DBM) consists of a network of collagen fibers that provide a sustained release of growth factors such as bone morphogenetic proteins. Previous studies have demonstrated that it can regenerate a fibrocartilaginous enthesis. HYPOTHESIS: The use of a DBM and mesenchymal stem cells (MSCs) at the healing enthesis will result in a higher bone mineral density at the tendon insertion and will enhance the regeneration of a morphologically superior enthesis when compared with an acellular human dermal matrix...

Several in vitro studies evaluated the cellular and molecular events related to interactions between phototherapy and target tissues, including oral keratinocytes and fibroblasts, providing elucidative data about phototherapy-induced healing. However, these interactions were limited to the application of a bidimensional cell culture model of oral mucosal cells. Thus, the present study evaluated the use of an organotypic oral epithelium model to elucidate the morphological and phenotypic responses of cells subjected to low-level laser therapy (LLLT)...

This retrospective study utilizes 3D imaging and mammometrics to compare implant-based breast reconstruction with and without the use of ADM. Previous studies have suggested improved aesthetic outcomes with the use of ADM, but none have been able to quantify this difference. Images were obtained at early and late time points following the expander-implant exchange procedure. Measurements included the point of maximum projection, the superior, inferior, medial and lateral volumetric distribution, and the distance from the point of maximum projection to the inframammary fold along the breast meridian...
