Correction of an animation deformity that developed from breast implant removal

Subpectoral implant insertion is considered to be the standard procedure for breast augmentation and reconstruction. However, in some patients who have undergone breast augmentation or reconstruction surgery with a prosthesis, implant removal may be required for various reasons, including infection or implant rupture. According to a literature review, the standard technique for implant removal has not been thoroughly investigated. This study aimed to report the case of a patient who developed animation deformity after implant removal and to suggest a technique for preventing such complications. A 51-year-old woman underwent breast augmentation surgery with silicone implants. However, the patient complained of an unpleasant foreign body sensation; hence, the implant was removed 6 months after the first operation. After removal of the implant, undesirable movement of the chest wall on both breasts occurred. Revision surgery under general anesthesia was planned 18 months after implant removal. Capsulectomy was performed on both sides, and the pectoralis major muscle was completely isolated and repositioned. The undesirable movement in the skin of the chest wall disappeared postoperatively. This case suggests the need for capsulectomy and repositioning of the pectoralis muscle to its original position during implant removal.ope

Treatment strategy for skin and soft tissue infections caused by nontuberculous mycobacteria following various procedures

Background The early diagnosis and treatment of skin and soft tissue infections caused by nontuberculous mycobacteria (NTM) are important, especially as infections with rapidly growing mycobacteria (RGM) are rare and difficult to diagnose and treat. Recently, we identified 22 cases of NTM infections; in this study, we suggest treatment strategies by analyzing the demographic characteristics and treatment progress of these patients. Methods A retrospective study of patients with NTM infections from 2009 to 2019 was conducted. To identify NTM infections, acid-fast bacillus (AFB) staining, Gram staining, polymerase chain reaction (PCR), and cultures of mycobacteria were performed. Empirical treatment with a combination of antibiotics or surgery was performed; species identification and drug susceptibility tests were performed by the Korean National Tuberculosis Association. The final regimen was determined after obtaining the test results. Results The mean incubation time of NTM was 4.32±2.88 weeks. RGM were detected in mycobacterial cultures in 21 of the 22 NTM patients. The results of AFB staining were negative in all patients, although PCR was positive for NTM in one patient. Fourteen patients were hospitalized for treatment with intravenous antibiotics and surgery. Treatment with a combined regimen of oral antibiotics was maintained for a mean of 5.41±1.85 months. Conclusions The unusual clinical manifestations of skin and soft tissue infections caused by NTM make them difficult to diagnose. Suspicion of NTM based on clinical presentation and a detailed examination should be followed by proper treatment involving multiple antibiotics and surgery in these patients.ope

Dual cortical tunneling method for endoscopic forehead lift

Background Endoscopic forehead lift with cortical tunneling is an effective option for rejuvenation of the upper third of the face. Although it has been considered safe and reliable, with relatively consistent long-term results, relapse and weakening of adhesion have been common problems. Methods We suggest the dual-tunneling method for overcoming these limitations. A total of 100 patients aged 17 to 65 years underwent forehead lifting with cortical tunneling by the senior author from August 2016 to December 2017. The single-tunnel method was applied in one half of the patients and the dual-tunnel method in the other half. Bilateral brow positions were measured immediately following surgery and 6 months later. Results For all cases, cortical tunneling was done at the central incision and both paramedian incisions; therefore, three tunnels were used in the control group and six tunnels in the experimental group. In the single-tunnel group, relapse distances were 2.39±0.83 mm for the medial brow and 3.26±0.91 mm for the lateral brow (6 months postoperatively; n=100). The dual-tunnel group showed significantly smaller (P<0.001) relapse distances, with values of 1.69±0.46 mm and 2.17±0.59 mm for the medial and lateral brow, respectively (6 months postoperatively; n=100). The experimental group did not show an increase in complications. Conclusions The dual-tunneling method, designed to minimize the cheese-wiring effect, uses a triangular plane to avoid a focal fixation. The fixation also includes the periosteum to hold the forehead tissue in place, inducing stronger adhesion.ope

3D CT Image Processing for 3D Printed Auricular Reconstruction of Unilateral Microtia Patient

Purpose Microtia is congenital anomaly of external ear and the reconstruction method for the external ear of microtia patient was based on autogenous costal cartilage framework. The application of 3D printing technique in medical science has made more possibility of human tissue restoration, and we tried to apply this technique in auricular reconstruction field. Materials and Methods As for unilateral microtia patient, the contralateral side ear is normal and reconstructive surgeon tried to mimic it for reconstruction of affected ear. So, we obtained facial CT scan of microtia patient and made mirror image of normal side ear. Moreover, to make the 3D scaffold based on the mirror image of normal ear and to apply this scaffold for the auricular reconstruction surgery, we included auriculocephalic sulcus and anterior fixation part. Results We could successfully obtain mirror image of normal ear, auriculocephalic sulcus and anterior fixation part for 3D scaffold printing. Conclusions Using this CT image processing and 3D printing technique, we will be able to make the scaffold for auricular reconstruction of unilateral microtia patient, and perform auricular reconstruction in near future.ope

Single-port robot-assisted prosthetic breast reconstruction with the da Vinci SP Surgical System: first clinical report

Robot-assisted nipple-sparing mastectomy with immediate reconstruction is currently performed in an attempt to seek smaller and indistinct incisions. Robotic surgery system has been evolving under the concept of minimal invasive technique which is a recent trend in surgery. One of the latest version is the da Vinci SP Surgical System (Intuitive Surgical). In this report, we will share our experiences. Two patients underwent robot-assisted nipple-sparing mastectomy, each followed by immediate robot-assisted expander insertion and prepectoral direct-to-implant breast reconstruction, respectively. There was no open conversion or major postoperative complication. One patient experienced mild infection, which was resolved by intravenous antibiotic treatment. Simple docking process, multi-joint instruments, and third-arm functionality are among the new surgical system's advantages. The present cases suggest that robot-assisted nipple-sparing mastectomy with immediate reconstruction using the da Vinci SP Surgical System is feasible and safe. The promising features and potential application of da Vinci SP in breast reconstruction need further study.ope

Ultrasonic dissection versus electrocautery for immediate prosthetic breast reconstruction

Background: Ultrasonic dissection devices cause less thermal damage to the surrounding tissue than monopolar electrosurgical devices. We compared the effects of using an ultrasonic dissection device or an electrocautery device during prosthetic breast reconstruction on seroma development and short-term postoperative complications. Methods: We retrospectively reviewed the medical records of patients who underwent implant-based reconstruction following mastectomy between March 2017 and September 2018. Mastectomy was performed by general surgeons and reconstruction by plastic surgeons. From March 2017 to January 2018, a monopolar electrosurgical device was used, and an ultrasonic dissection device was used thereafter. The other surgical. Methods: were the same in both groups. Results: The incidence of seroma was lower in the ultrasonic dissection device group than in the electrocautery group (11 [17.2%] vs. 18 [31.0%]; P=0.090). The duration of surgery, total drainage volume, duration of drainage, overall complication rate, surgical site infection rate, and flap necrosis rate were comparable between the groups. Multivariate analysis revealed that the risk of seroma development was significantly lower in the ultrasonic dissection device group than in the electrocautery group (odds ratio for electrocautery, 3.252; 95% confidence interval, 1.242-8.516; P=0.016). Conclusions: The findings of this study suggest that the incidence of seroma can be reduced slightly by using an ultrasonic dissection device for prosthesis-based breast reconstruction. However, further randomized controlled studies are required to verify our. Results: and to assess the cost-effectiveness of this technique.ope

A Prospective Randomized Study: The Usefulness and Efficacy of Negative Pressure Wound Therapy with Lipidocolloid Polyester Mesh Compared to Traditional Negative Pressure Wound Therapy for Treatment of Pressure Ulcers

To improve healing of pressure ulcer wounds, it is important to optimize the conditions of the area surrounding the wound. Negative pressure wound therapy (NPWT) promotes wound healing, however, the removal of NPWT can cause pain or focal bleeding, delaying wound healing or causing infection. In this study, we reviewed the efficacy of the lipidocolloid non-adherent dressing (Urgotul®) as a wound contact layer. A total of 38 patients from the same facility who applied NPWT from April 2016 to October 2019 were included and divided into two groups; NPWT with the lipidocolloid non-adherent dressing (group 1, experimental group, 19 patients) and NPWT only (group 2, control group, 19 patients). The condition of the wound was examined prior to NPWT application, at one week, and again at three weeks after application. No significant differences were found between groups for general characteristics, bacterial culture or photo analysis. However, when comparing groups based on the time of examination, there was a significant reduction of the wound size in group 1 (p = 0.001) but not in group 2 (p = 0.082). Therefore, the current study finds that using the lipidocolloid non-adherent dressing as a wound contact layer in NPWT stimulates healing by shrinking the size of the pressure ulcer wound.ope

Reconstruction of Ankle and Heel Defects with Peroneal Artery Perforator-Based Pedicled Flaps

BACKGROUND: The reconstruction of ankle and heel defects remains a significant problem for plastic surgeons. The following options exist for reconstructing such defects: local random flaps, reverse flow island flaps, and free flaps. However, each of these methods has certain drawbacks. Peroneal artery perforators have many advantages; in particular, they are predictable and reliable for ankle and heel reconstructions. In this study, we report our clinical experience with peroneal artery perforator-based pedicled flaps in ankle and heel reconstructions. METHODS: From July 2005 to October 2012, 12 patients underwent the reconstruction of soft tissue defects in the ankle and heel using a peroneal artery perforator-based pedicled flap. These 12 cases were classified according to the anatomical area involved. The cause of the wound, comorbidities, flap size, operative results, and complications were analyzed through retrospective chart review. RESULTS: The mean age of the patients was 52.4 years. The size of the flaps ranged from 5×4 to 20×8 cm(2). The defects were classified into two groups based on whether they occurred in the Achilles tendon (n=9) or heel pad (n=3). In all 12 patients, complete flap survival was achieved without significant complications; however, two patients experienced minor wound dehiscence. Nevertheless, these wounds healed in response to subsequent debridement and conservative management. No patient had any functional deficits of the lower extremities. CONCLUSIONS: Peroneal artery perforator-based pedicled flaps were found to be a useful option for the reconstruction of soft tissue defects of the ankle and heel.ope
