VGG19 demonstrates the highest accuracy rate in a nine-class wound classification task among various deep learning networks: a pilot study.

Background: Current literature suggests relatively low accuracy of multi-class wound classification tasks using deep learning networks. Solutions are needed to address the increasing diagnostic burden of wounds on wound care professionals and to aid non-wound care professionals in wound management.

Objective: To develop a reliable, accurate 9-class classification system to aid wound care professionals and perhaps eventually, patients and non-wound care professionals, in managing wounds.

Lymphatic complex transfer as combined lymph vessel and node transfer for advanced stage upper extremity lymphedema.

Objective: Lymphedema, especially in the advanced stage, is a growing challenge in extremity reconstruction, with few applicable surgical methods. Despite its importance, no consensus has been reached regarding a single surgical method yet. Herein, the authors introduce a novel concept of lymphatic reconstruction yielding promising results.

Comparing Complications of Biologic and Synthetic Mesh in Breast Reconstruction: A Systematic Review and Network Meta-Analysis.

 In breast reconstruction, synthetic meshes are frequently used to replace acellular dermal matrix (ADM), since ADM is expensive and often leads to complications. However, there is limited evidence that compares the types of substitutes. This study aimed to compare complications between materials via a network meta-analysis.

Epidemiological characteristics and importance of lobulation of giant epidermal cysts: An 18-year retrospective review of 19 cases.

Giant epidermal cysts, which have a diameter of ≥5 cm, have rarely been reported. Giant epidermal cysts that have multiple lobules are referred to as multilocular giant epidermal cysts. This study aims to establish the epidemiological characteristics and statistically determine the significance of lobulation in giant epidermal cysts.

Establishment and characterization of two human cutaneous angiosarcoma cell lines, KU-CAS3 and KU-CAS5.

Background: Cutaneous angiosarcoma (CAS) is a rare but fatal cancer. Established CAS cell lines are necessary for the investigation of their properties and treatment options.

Methods: Two cell lines, KU-CAS3 and KU-CAS5, were established from human angiosarcoma specimens obtained from the scalp.

Overcome the barriers of the skin: exosome therapy.

Exosomes are nano-sized cargos with a lipid bilayer structure carrying diverse biomolecules including lipids, proteins, and nucleic acids. These small vesicles are secreted by most types of cells to communicate with each other. Since exosomes circulate through bodily fluids, they can transfer information not only to local cells but also to remote cells.

Vascularized lymph node transfer for surgical treatments of upper versus lower extremity lymphedema.

Objective: The purpose of this study was to compare clinical outcomes after vascularized lymph node transfer (VLNT) for the treatment of lymphedema performed on the upper and lower extremities.

Methods: Between April 2015 and January 2020, 71 patients with advanced-stage lymphedema, categorized as International Society of Lymphology late stage 2 or 3, who underwent VLNT in upper and lower extremities were included in this study. Thirty-seven and 34 patients underwent VLNT in upper and lower extremities, respectively.

Aesthetic Comparison of Abdominal Donor Site Scar Between Absorbable Dermal Staple and Subcutaneous Suture after Autologous Breast Reconstruction: A Prospective Randomized Controlled, Double-Blinded Study.

Background: Abdominal tissue transfer has become the most commonly used tool for breast reconstruction. However, a secondary operator is often responsible for donor closure, which leaves dissatisfaction to patients due to inconsistent donor scars. Now, an absorbable dermal stapler is popularized worldwide and currently used for wound closure in many surgical fields.

Clinical Experience with Treatment of Aquafilling Filler-Associated Complications: A Retrospective Study of 146 Cases.

Background: Aquafilling filler is used for breast and buttock augmentation, which are the most commonly performed cosmetic surgery procedures. However, complications after using Aquafilling filler for breast augmentation have been reported, and there are concerns regarding its use in large areas, such as the buttocks. We provide our experience with complications after breast augmentation and buttock augmentation using Aquafilling filler.

Surgical Correction of Upper Eyelid Ectropion Presenting Dry Eye Symptoms.

Background: Upper eyelid ectropion occurs as a post-blepharoplasty complication or involution change, and it causes dry eye symptoms that cannot be resolved with conservative management.

Objectives: The aim of this study is to describe the authors' surgical technique of anatomical correction of upper eyelid ectropion, including tarsal scoring incision.

Methods: The technique involves the following 4 steps: (1) adhesiolysis at the preaponeurotic layer; (2) undermining and redraping of the pretarsal flap in a pretarsal plane; (3) optional, partial thickness tarsal scoring incision over the central two-thirds; and (4) downward repositioning of the pretarsal flap and lower fixation to the tarsus.

Use of a biopsy punch for end-to-side anastomosis in free-tissue transfer.

In end-to-side vessel-anastomoses, a side fenestration should be made by a slit incision or partial excision of the vessel wall. However, a slit incision might restrict blood flow across the anastomosis, and a partial vessel wall excision using micro-scissors may be time-consuming and result in irregular edges, which may weaken the vessel wall and cause flow disturbances. We used a biopsy punch for end-to-side anastomosis, and obtained satisfactory results.

Ophthalmoplegia with skin necrosis after a hyaluronic acid filler injection.

Hyaluronic acid filler injection is commonly used for aesthetic purposes. However, many clinicians neglect the possibility of developing vascular occlusion and its devastating sequelae. Besides visual loss after iatrogenic ophthalmic artery occlusion, ophthalmoplegia without blindness is rare but may occur.

Use of a multilayered acellular dermal substitute with simultaneous full-thickness skin graft for the one-stage coverage of nasal skin defects.

Background: Nasal skin defect closures are challenging because the nose is a complex anatomic structure with several subunits, and the nasal tip and ala represent particularly difficult subunits to reconstruct. The traditional full-thickness skin graft (FTSG) is an easy and well-established method, but often results in undesirable outcomes in terms of the nasal contour caused by a lack of dermal tissue.

Aims: The purpose of the study is to report the outcomes of the simultaneous application of the acellular dermal substitute (Matriderm ) with FTSG in the treatment of nasal skin defects.

Dual vascular free transverse rectus abdominis myocutaneous flap for hemifacial reconstruction in a vessel-depleted neck.

Cutaneous squamous cell carcinoma (SCC) is the second most common skin malignancy. This report describes the case of an unusual extensive SCC involving the whole hemiface, which required reconstruction with a combination of a dual vascular free transverse rectus abdominis muscle (TRAM) flap and a skin graft. A 79-year-old woman visited our hospital with multiple large ulcerated erythematous patches on her right hemiface, including the parieto-temporal scalp, bulbar and palpebral conjunctiva, cheek, and lip.

The Outcome of Early Ablative Fractional Laser Treatment for Thyroidectomy Scars.

Background And Objectives: Ablative fractional laser (AFL) systems are commonly used to treat various scars, and recent research has indicated that early treatment with AFL may have a preventive effect on scars. This study was designed to evaluate the efficacy of early treatment with a 10,600 nm carbon dioxide (CO ) AFL on thyroidectomy scars and compare it to late (conventional) treatment for the same and untreated controls.

Study Design/materials And Methods: We performed a prospective, evaluator-blinded, split-scar study on fresh thyroidectomy scars between July 2014 and July 2017.

The authors share our experience of immediate reconstruction using amputated cartilage and discuss the advantages compared to other techniques of reconstruction.

Materials And Methods: The authors retrospectively reviewed the medical records of 3 patients who underwent immediate reconstruction of amputated ear by a single operator.

Protective Effect of Botulinum Toxin against Ultraviolet-Induced Skin Pigmentation.

Background: Hyperpigmentation following ultraviolet irradiation has cosmetic concerns. Botulinum toxin type A can favorably affect skin pigmentation. However, the mechanism of skin pigmentation is unclear.

De-epithelialized dermal flap for nipple reconstruction: A modified star flap.

Background: Multiple approaches for nipple reconstruction exist, and none is considered superior to all others. The star flap is one of the most popular methods for nipple reconstruction, but gradual height loss is a major concern. We present a new modification of the star flap that incorporates a de-epithelialized dermal flap, along with the associated surgical results.

Mandibular reconstruction using customized three-dimensional titanium implant.

Mandibular defects lead to severe deformation and functional deficiency. Vascularized osteocutaneous tissue has been widely used to reconstruct the mandible. However, it is technically challenging to shape this type of grafts in such a manner that they resemble the configuration of the mandible.

Lymphatic vessel mapping in the upper extremities of a healthy Korean population.

Background: Intraoperative indocyanine green (ICG) lymphography can effectively detect functioning lymph vessels in edematous limbs. However, it is sometimes difficult to clearly identify their course in later-stage edematous limbs. For this reason, many surgeons rely on experience when they decide where to make the skin incision to locate the lymphatic vessels.

Analysis of the Factors Affecting Surgical Site Infection and Bone Flap Resorption after Cranioplasty with Autologous Cryopreserved Bone: The Importance of Temporalis Muscle Preservation.

Aim: To investigate the outcomes and associated complications after delayed cranioplasty using autologous, cryopreserved bone.

Material And Methods: This retrospective study included 57 consecutive patients treated with cranioplasty with autologous cryopreserved bone for various conditions causing increased intracranial pressure due to brain swelling. The incidence and risk factor of surgical site infection (SSI) and bone flap resorption were analyzed.

Prognostic Factors of Orbital Fractures with Muscle Incarceration.

Background: Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT) evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration.

Transconjuctival Incision with Lateral Paracanthal Extension for Corrective Osteotomy of Malunioned Zygoma.

Background: Conventional correction of malunioned zygoma requires complete regional exposure through a bicoronal flap combined with a lower eyelid incision and an upper buccal sulcus incision. However, there are many potential complications following bicoronal incisions, such as infection, hematoma, alopecia, scarring and nerve injury. We have adopted a zygomaticofrontal suture osteotomy technique using transconjunctival incision with lateral paracanthal extension.
