Background After peripheral nerve injury, there is an increase in calcium concentration in the injured nerves. Our previous publications have shown that increase in calcium concentration correlated well with degree of nerve injury and that local infusion of calcitonin has a beneficial effect on nerve recovery. Schwann cells play a pivotal role in regeneration and recovery. We aim to examine cultured Schwann cell survivals in various concentrations of calcium-containing growth media and the effect of calcitonin in such media...

Background For large tongue defects, reconstructive surgeons have devised a variety of feasible options, such as radial forearm free flap and anterolateral thigh (ALT) flap. In our institution, peroneal flap has been the workhorse flap for the soft tissue defect in head and neck reconstruction. We present our experience using peroneal flap in tongue reconstruction. Patients and Methods The study included 47 patients who had undergone tongue reconstructions with peroneal flaps after tumor resection. The size and location of the defect after tumor resection determined whether the peroneal flaps could be harvested as pure septocutaneous flaps to solely reconstruct the neotongue or to carry an additional muscle bulk to fill the adjacent defect...

Background This study aimed to confirm the feasibility and reliability of saphenous artery (SA) and great saphenous vein (GSV) anastomosis as a new supermicrosurgery training model and to compare the one-way-up anastomosis with the currently used end-to-end anastomosis technique. Methods Twenty supermicrosurgical anastomoses were performed in 10 Sprague Dawley rats. The external diameters of SA and GSV were measured using Leica LAS EZ software. The right-side SA and GSV anastomoses were performed using the standard end-to-end anastomosis technique...

Background Three-dimensional (3D) printing has developed as a revolutionary technology with the capacity to design accurate physical models in preoperative planning. We present our experience in surgeon-based design of 3D models, using home 3D software and printing technology for use as an adjunct in vascularized bone transfer. Methods Home 3D printing techniques were used in the design and execution of vascularized bone flap transfers to the upper extremity. Open source imaging software was used to convert preoperative computed tomography scans and create 3D models...

Background Optimal outcomes in microsurgery have been attributed to a range of factors, with performing of end-to-end (ETE) versus end-to-side (ETS) influencing anastomotic complications and flap outcomes. Methods A systematic review of the literature and meta-analysis was undertaken to evaluate the relative risks of anastomotic complications with ETE versus ETS approaches, for arterial and venous anastomoses looking at risk ratios (RRs) for thrombosis and overall flap failure. Results RRs of thrombosis and flap failure in ETS versus ETE venous anastomosis groups were 1...

Background Microvascular anastomotic patency is fundamental to head and neck free flap reconstructive success. The aims of this study were to identify factors associated with intraoperative arterial anastomotic issues and analyze the impact on subsequent complications and cost in head and neck reconstruction. Methods A retrospective review was performed on all head and neck free flap reconstructions from 2005 to 2013. Patients with intraoperative, arterial anastomotic difficulties were compared with patients without...

Background Although flap transfer is a popular reconstructive procedure with a high success rate, it is associated with a high complication rate and low salvage rate. During the past decade, negative-pressure wound therapy (NPWT) has been increasingly applied to facilitate flap transfer and salvage flaps threatened by complications. It has achieved some success, but its efficacy and safety remain controversial because of the limited number of reports and lack of systematic reviews. Methods English-language articles describing the application of NPWT on flaps were screened using predetermined inclusion and exclusion criteria...

Background Basic fibroblast growth factor (bFGF) is known to stimulate bone formation and angiogenesis. Hydroxyapatite/collagen composite (HAp/Col) is also known to have very strong bone conductive activity. In this study, prefabrication of vascularized allogenic bone (allo-bone) graft was attempted in recipients by implanting vascular bundles from recipients into the transplanted allo-bone graft. Furthermore, the effect of bFGF-containing HAp/Col on the prefabricated vascularized allo-bone graft was investigated...

Background Immediate breast reconstruction (IBR) is often deferred, when postmastectomy radiotherapy (PMRT) is anticipated, due to high complication rates. Nonetheless, because of robust data supporting improved health-related quality of life associated with reconstruction, physicians and patients may be more accepting of tradeoffs. The current study explores national trends of IBR utilization rates and methods in the setting of PMRT, using the National Cancer Database (NCDB). The study hypothesis is that prosthetic techniques have become the most common method of IBR in the setting of PMRT...

Background In patients with head and neck squamous cell carcinoma (HNSCC), disease recurrence remains a significant obstacle to long-term survival. If possible, surgical salvage with reconstruction remains the best treatment option for patients with recurrence. Currently, there is no literature discussing whether age should preclude microvascular reconstruction in these patients. We hypothesize that older age alone does not affect outcomes. Methods A retrospective chart review of patients with HNSCC at our institution between 2008 and 2015 was performed...

Background The use of distally based neurocutaneous sural flaps (DBNCSF) is one of the most common methods of reconstructing the distal lower leg. However, they have developed a bad reputation because of their propensity for venous engorgement. Venous congestion that can lead to distal necrosis can be prevented by venous supercharging. Using a prospective comparative study, we thus explored the effect of venous supercharging on the reliability of these useful workhorse flaps. Methods We prospectively included 38 patients who received a conventional DBNCSF and 38 patients who received a supercharged version of this flap (sDBNCSF) between January 2012 and July 2016...

Background Although conservative management of lymphedema remains the first-line approach, surgery is effective in select patients. The purpose of this study was to review the literature and develop a treatment algorithm based on the highest quality lymphedema research. Methods A systematic literature review was performed to examine the surgical treatments for lymphedema. Studies were categorized into five groups describing excision, liposuction, lymphovenous anastomosis (LVA), vascularized lymph node transfer (VLNT), and combined/multiple approaches...

More than 250,000 women will be diagnosed with invasive breast cancer in the United States in 2017 alone. A large number of these patients will undergo mastectomy and will be candidates for immediate breast reconstruction. The most common reconstructive options are either implant-based or autologous tissue reconstruction, with the latter having been reported to have higher rates of long-term patient satisfaction, lower cost, and less postoperative pain. A subset of patients, however, may not be ideal candidates for autologous microsurgical reconstruction, for example, due to inadequate abdominal tissues, yet they may desire this reconstructive modality...

Background This study was designed to assess the changes of acetylcholine receptor (AChR) and creatine kinase (CK) levels, which are important biochemical markers for muscle viability in cases of long-term muscle denervation. Scientists and peripheral nerve surgeons may find these data important regarding maximal range of muscle viability applicable for timing of effective peripheral nerve reconstructive surgery. Methods The study was conducted on 48 rats (96 gastrocnemius muscles), whose right legs were denervated by removing a 10-mm segment of sciatic nerve, while their left legs remained intact...

Background Autologous breast reconstruction has been noted in the literature to provide superior aesthetic outcomes and patient satisfaction. Additionally, free perforator flap tissue transfer has the potential for lower abdominal donor site morbidity. However, it has been noted that the percentage of women who are undergoing autologous breast reconstruction in the United States is decreasing. Factors related to the technical difficulty, prolonged operative times, and decreasing reimbursement have been implicated as the causes...
