Reconstruction of the Foot Using a Superficial Inferior Epigastric Artery Free Flap.

When foot reconstruction is performed in the pretibial area, the ankle, or the dorsum of the foot, the need for a reliable flap remains a challenge. We found that the superficial inferior epigastric artery (SIEA) free flap can be used as an alternative tool for this purpose, as it helps to solve the problems associated with other flaps. We describe 2 cases in which we reconstructed the foot using an SIEA free flap, which was pliable enough to fit the contours of the area.

The Lazy S Design: A Novel Skin Closure Design in Skin-Sparing Mastectomy for Implant-Based Breast Reconstruction.

Preservation of the breast skin envelope during immediate implant-based breast reconstruction is important for producing symmetrical and natural-looking breasts. We propose the lazy S design for the closure of round-shaped wounds with the hope of improving the aesthetic outcomes and reducing the tension on the wound by preserving the skin. Additionally, the direction of tension is dispersed due to the shape of this design.

Deep-Plane Lipoabdominoplasty in East Asians.

Background: The objective of this study was to develop a new surgical technique by combining traditional abdominoplasty with liposuction. This combination of operations permits simpler and more accurate management of various abdominal deformities. In lipoabdominoplasty, the combination of techniques is of paramount concern.

Methylene blue dye-induced skin necrosis in immediate breast reconstruction: evaluation and management.

Background: For early breast cancer patients, skin-sparing mastectomy or nipple-sparing mastectomy with sentinel lymph node biopsy has become the mainstream treatment for immediate breast reconstruction in possible cases. However, a few cases of skin necrosis caused by methylene blue dye (MBD) used for sentinel lymph node localization have been reported.

Methods: Immediate breast reconstruction using a silicone implant was performed on 35 breasts of 34 patients after mastectomy.

The effects of sterilization methods on lyophilized cartilage grafts in an experimental model.

Background: Cartilage graft is an effective method for reconstructing the bony framework of the face and covering the bony defect site. As a process method of cartilages, lyophilization has the advantages of long-term storage and easy handling. We hypothesized that the type of procedure used to sterilize lyophilized cartilage may affect outcomes after implantation into the body.

The effects of botulinum toxin A on survival of rat TRAM flap with vertical midline scar.

The transverse rectus abdominis musculocutaneous (TRAM) flap has been widely used in various reconstructive surgeries. Recently, there have been reports regarding the positive effect of botulinum toxin A (BoTA) on flap survival. We hypothesized that pretreatment with BoTA could augment the survival of pedicled TRAM flaps with a vertical midline scar.

Analysis of 15 cases of auricular keloids following conchal cartilage grafts in an asian population.

Background: Recently, rhinoplasty techniques have advanced significantly and are frequently combined with columellar struts using conchal cartilage grafts to sufficiently reshape the nasal tip. For this reason, auricular keloids following harvesting of conchal cartilage grafts are expected to occur with greater frequency. The aim of this study was to share our experiences with auricular keloids and to suggest possible risk factors.

Clinical experience with complications of hand rejuvenation.

Purpose: Prominent signs of ageing of the hands have recently been treated with permanent or longer-lasting injectable dermal fillers. However, few previous studies have described the long-term complications of such hand rejuvenation. The purpose of our report was to share our experience of 15 cases with long-term complications following hand rejuvenation using various medical fillers.

Three-dimensional circumferential liposuction of the overweight or obese upper arm.

Unlabelled: Due to recent trends in liposuction, anatomic consideration of the body's fatty layers is essential. Based on this knowledge, a circumferential approach to achieving maximal aesthetic results is highlighted. In the upper arm, aspiration of fat from only the posterolateral region can result in skin flaccidity and disharmony of the overall balance of the upper arm contour.

Solitary Langerhans cell histiocytosis arising from sternum: a case report.

Langerhans cell histiocytosis (LCH) is a rare idiopathic benign disease characterized by proliferation of Langerhans cells, most commonly in the skull. In extremely rare cases, the tumor can occur in the sternum. A 4-year-old girl presented to our institution with a firm, nontender mass in her anterior chest that had indolently enlarged to approximately 2 cm in diameter over the previous several months.

Earlobe keloids: classification according to gross morphology determines proper surgical approach.

Background: A previous study described the outcomes of a treatment protocol using a prospective design and identified three clinical risk factors for recurrent keloids.

Objective: To introduce a novel classification of earlobe keloids through a retrospective study and describe the appropriate surgical methods according to this new classification.

Methods: One thousand twenty-seven earlobe keloids were treated at Kangbuk Samsung Hospital from March 2001 to February 2011.

Clinical experience with polymethylmethacrylate microsphere filler complications.

Polymethylmethacrylate (PMMA) filler is widely used for the correction of wrinkles because of its relative long-lasting cosmetic improvements and the rarity of reported complications. However, early and delayed complications, ranging from minor to severe, can occur following PMMA filler injection. We evaluated and treated 13 cases of PMMA filler-related complications that were referred to our institution from July 2005 to June 2010.

Clinical outcome in a series of 173 cases of foreign body granuloma: improved outcomes with a novel surgical technique.
