Autologous fat grafting evolved over the twentieth century to become a quick, safe, and reliable method for restoring volume. However, autologous grafts have some problems including uncertain viability of grafted low rate graft survival. To overcome associated with grafts, we used uncultured adipose tissue-derived stromal cell (stromal vascular fraction, SVF) assisted grafting. Thus, purpose this study was evaluate effect SVF in clinical trial.SVF cells were freshly isolated from half...

A prospective study of anatomic variations the median nerve and its relationship to surrounding structures was performed 354 consecutive operations in 192 patients with carpal tunnel syndrome at Korea University Anam Hospital from July 1995 September 1997. total 184 were women 8 men. 162 bilateral 30 unilateral. Regarding course motor branch, extraligamentous type most common (96.1%, 340 patients). 81.1% (N = 287) had origin branch radial side (or one third), 17.2% 61) anterior portion...

Although many studies have suggested that human adipose tissue contains pluripotent stem cells, a few reports are available on stromal vascular fraction (SVF). In the present study, we evaluated bone formation capacities of SVF. We implanted uncultured freshly isolated adipose-derived cells combined with demineralized matrix (DBM) to induce regeneration in critically sized rat calvarial defect model. used DBM (DBX(®)) and/or poly(70L-lactide-co-30DL-lactide) copolymer PLA as scaffold. Fifty...

Autologous or implant-based breast reconstruction after nipple-sparing mastectomy is increasingly preferred worldwide as a cancer treatment option. However, postoperative nipple-areola complex (NAC) necrosis the most significant complication of mastectomy. The purpose our study was to identify risk factors for NAC necrosis, and describe use skin-banking technique solution.We reviewed cases immediate autologous at institution between June 2005 January 2014. patients' data were analyzed based...

Background: Several investigators have postulated that human adipose-derived stem cells can be used for skin rejuvenation, but there been few reports about their direct effects on epidermal melanocytes. The authors studied the melanocytes, and causative agent of those was further investigated in this study. Methods: Human melanocytes were divided into three groups cultured cell–conditioned medium, dermal fibroblast–conditioned or control medium. Concentrations melanogenic cytokines these...

Human adipose tissue contains pluripotent stem cells that are similar to bone marrow-derived cells. The present study examined whether osteogenic induced adipose-derived (ASCs) could enhance the capacity of demineralized matrix and accelerate formation in a rat critically-sized calvarial defect model.Forty Sprague-Dawley rats were divided randomly into four groups containing 10 per each group (Control, 0.05 cc fibrin glue (25 mg/ml) thrombin (130 U/ml); DBX, control + 0.2 g DBX�; ASC, DBX 1...

Skin flap necrosis is a common complication after mastectomy and breast reconstruction. It has been proven that nitroglycerin ointment, as topical vasodilator, can decrease the rate of skin However, cause several side effects, including headache, dizziness, hypotension. The purpose this study was to evaluate whether application low dose ointment reduced in reconstruction skin-sparing or nipple-sparing mastectomy.A total 73 cases at our institution from March 2012 January 2017 were...

When performing lymphovenous anastomosis, it is sometimes difficult to find venules in the proximity of an ideal lymphatic vessel that have a similar diameter vessel. In this situation, larger can be used.The authors evaluated efficacy and patient satisfaction with bypass sleeve-in anastomosis. Between January 2014 December 2016, we performed procedure 18 patients (eight upper extremities 10 lower extremities) secondary lymphedema. Lymphovenous anastomosis was under microscopy after...

In Brief A prominent mandibular angle is considered to be unattractive in Asians because it gives the face a square, coarse, and muscular appearance. Asian women desire have an ovoid, reduced, slender by aesthetic resection. Mandibular ostectomy has been known effective satisfy both surgeons patients. Especially Korea, become as popular facial bone contouring surgery, which reduces lower width. However, narrow surgical field hinders direct view of site, making procedure that rather difficult...

When exposing the orbit, transconjunctival approach is regarded to have limited surgical exposure. The aim of this study demonstrate versatile usability extended approach, which can be medially and laterally, in reconstruction medial orbital wall, floor, even lateral rim maxillo-malar complex fracture. We reviewed 122 cases fractures treated with approach. operative results were assessed by postoperative CT scan reviewing complications. provided sufficient exposures all cases. There was no...

Objectives The choice to manage isolated frontal sinus anterior wall fractures without the involvement of nasofrontal outflow tract is mainly based on aesthetic concern and depends largely surgeons' preferences. Minimally depressed can be monitored by observation only with little risk long-term morbidity contour deformity. purposes this study were evaluate course a nonoperated fracture identify cutoff value displacement requiring surgical correction. Materials Methods A retrospective chart...

Open thyroidectomy is conventionally performed at the anterior side of neck, which a body part with comparatively great degree open exposure; due to this, postoperative scarring may cause distress in patients. We aimed compare effects ablative and nonablative fractional laser treatments on scars. examined medical records retrospective manner analyzed scars based their digital images by using modified Manchester Scar Scale (mMSS).Between February 2012 May 2013, 55 patients were treated (34...

An immediate lymphatic reconstruction (ILR) combining axillary reverse mapping (ARLM) and lymphovenous anastomosis (LVA) has been gradually in the spotlight as a novel surgical technique to prevent lymphedema. In this study, we investigate preventive effect of ILR for risk upper extremity We will compare incidence postoperative lymphedema between treatment group no-try or failure during same period with analysis effects different variables.In retrospective cohort analyzed 213 patients who...

Background: Despite the increasing interest in mesotherapy as an alternative method for body contouring, there are few reports of its safety, efficacy, and mechanism action. A clinical examination was performed to evaluate efficacy contouring. Methods: Twenty women were enrolled this prospective, case-controlled study over a 12-week period. The authors injected mixed solution (i.e., aminophylline, buflomedil, lidocaine) into superficial dermis medial aspect one thigh weekly using mechanical...

Premedication with pronase, dimethylpolysiloxane, and sodium bicarbonate improves visibility during upper gastrointestinal (UGI) endoscopy. However, the optimal time for this combination to take effect is unknown. We investigated of pre-UGI endoscopy medication.A randomized, investigator-blind, controlled trial. The 300 patients who were receive premedication randomized into 3 groups according following medication before UGI endoscopy: 10 minutes (group A, n=98), 30 B, n=97), C, n=99)....

The advance in microsurgical technique has facilitated a proper approach for reconstruction of extensive head and neck defects. For the success free tissue reconstruction, selection recipient vessel is one most important factors. However, vascular anatomy this region very complex, clear guideline about subject still lacking. In study, we present our 30 years experiences defects.In retrospective analyzed total 138 flaps 127 patients who underwent using transfer following tumor resection...

Ablative fractional laser (AFL) systems are commonly used to treat various scars, and recent reports have indicated that early scar treatment with lasers has good aesthetic results. Some scars respond dramatically AFL treatment, incurring high levels of patient satisfaction; however, other poorly or became worse after treatment. This study was designed clarify prognostic factors predict outcomes. A total 108 patients were included in this study. The treatments repeated every 4 weeks until...

Background The radial forearm flap is a versatile, widely used flap. However, the possibility of donor site complications has led to concern over its use. Some surgeons prefer using other flaps whose sites can be closed primarily with less morbidity, including avoiding unpleasant scarring. in our experience, stability reliably achieved by well-implemented specific procedures. Here, we present collection cases and investigate factors that affect aesthetic results as basis for reference...
