Since April 2015, post-mastectomy breast reconstruction has been covered by the Korean National Health Insurance Service (NHIS). The frequency of these procedures increased very rapidly. We analyzed data obtained from Big Data Hub Review and Assessment (HIRA) determined annual changes in number related trends Korea. evaluated numbers mastectomy performed between 2015 December 2018 using HIRA Hub. total, autologous, implant reconstructions after NHIS coverage commenced. were Microsoft Excel....
Background: The goal of sole reconstruction should be functional and aesthetic. These goals can achieved by providing the with a durable comfortable weight-bearing surface, adequate contour, protective sensation, solid anchoring to deep tissue resist shearing. Various flaps such as fasciocutaneous, musculocutaneous, or split skin grafted muscle have been reported for foot. perforator flap, however, deserves attention in debate ideal flap because its anatomical characteristics. Methods:...
Background: Immediate breast reconstruction using the transverse rectus abdominis musculocutaneous (TRAM) flap is associated with multiple risk factors for pulmonary thromboembolism, incidence of which has been reported to be as high 6.3 percent. The authors conducted a prospective study efficacy prophylactic use low-molecular-weight heparin prevent thromboembolism. Methods: Six hundred fifty consecutive patients who underwent immediate TRAM flaps between August 2001 and April 2007 were...
Negative pressure therapy has been used in various conditions to promote wound healing. It also secure a skin graft by improving microcirculation and providing tight adhesion between the recipient bed. The authors coupled idea of negative for 1-stage allodermis split-thickness graft. This prospective study presents 47 cases defects treated patients were divided into 2 groups either with simultaneous aid 5 days (group 1, n = 37) or classic tieover dressing 2, 10). In group 97.8% take was...
This prospective study searches for the clinical relevance of preoperative multidetector row computed tomography (MDCT) angiography (CTA) anterolateral thigh (ALT) free flap.Preoperative CTA data were collected in 100 patients between November 2004 and April 2008, from 139 limbs evaluated number, type, location ALT perforators. information was used as operative roadmap correlated with intraoperative findings 58 patients.The MDCT revealed an average number perforators 2.28 per unilateral...
Surgical ablation for locally advanced breast cancer results in large chest wall defects, which can then be managed with local flaps or skin grafts. The purpose of this article is to evaluate the outcomes three types flaps.Among 25 24 patients, 6 were bilateral advancement (BA) flaps, 9 thoracoabdominal (TA) and 10 thoracoepigastric (TE) flaps. Clinical compared including complications, need a secondary surgical intervention, timing adjuvant therapy.The mean defect size was 436.2 cm(2). Two...
The MEK inhibitor, selumetinib, reduces plexiform neurofibroma (PN) in pediatric patients with neurofibromatosis type 1 (NF1). Its safety and efficacy adults PN effectiveness other NF1 manifestations (eg, neurocognitive function, growth reduction, café-au-lait spots) are unknown.
Background: A serious drawback of the deep inferior epigastric perforator (DIEP) flap is an abdominal scar that too high. Because umbilicus should be incorporated into territory, lowering very difficult. This report describes a new DIEP design where placed in lowermost part abdomen, well below umbilicus, similar to mini-abdominoplasty. Methods: The low was used only for cases with moderately sized breasts and reliable perforators way umbilicus. flap's lower border on pubic rim upper usually...
The purpose of this study was to determine the risk factors associated with mastectomy skin flap necrosis during immediate reconstruction TRAM or DIEP flaps.This reviewed 1116 cases breast over 10 years. Patients ranged in age from 29-76 years (average = 45.1 years), and had an average follow-up period 65.6 months. Thirteen (age, BMI (body mass index), smoking habits, diabetes ptosis grade, midclavicle-to-nipple distance, neoadjuvant chemotherapy, free pedicled flap, method, surgeon, stage,...
Although bottle-feeding after cheiloplasty is widely accepted, postoperative feeding regimen palatoplasty still controversial. The aim of this prospective randomized study was to evaluate the effect on early course in a relatively homogeneous group patients. Eighty-two consecutive patients with nonsyndromic cleft palate undergoing 2-flap by single surgeon were from bottle usual nipple (G1, N = 42) or spoon, cup, syringe (G2, 40). Complication rates, sedative use, oral intake for first 6...
In Brief Fat necrosis in transverse rectus abdominis musculocutaneous (TRAM) flap is considered to be mainly affected by blood supply. This prospective study compares the incidence of fat between zones II and III 400 consecutive patients who had undergone unipedicled TRAM breast reconstruction. Fifty-eight (14.5%) suffered from necrosis, 7 2 separate nodules. Fifty-four occurred zone II, 10 III, 1 I. The was significantly higher than (P < 0.001). weight mastectomy specimen relative amount...
Although free flap has largely replaced pedicled transverse rectus abdominis musculocutaneous (TRAM) flap, the latter also evolved by increased understanding of anatomy and physiology. We report outcomes in 500 consecutive TRAM Asian patients performed a single surgeon, providing incidences complications ideas prevention. Fascia was minimally harvested with full width muscle. The eighth intercostals nerve severed back-cut made at lateral belly. Anterior sheath directly repaired. Breast...
