The Effective Fixation Level for Cosmetic Lateral Canthoplasty.

Background: In previous reports of lateral canthoplasty, the components of the inferior retinaculum were mostly secured to the lateral orbital rim at a level around the pupil or superior limbus. However, that level is not adjustable in young patients who want to lengthen the short palpebral fissure for cosmetic purposes. Moreover, the anchoring method based on the palpebral portion can also be inconvenient and ineffective.

A New Double Trapezoid-Shaped Osteotomy for Reduction Malarplasty.

Background: Various surgical techniques have been introduced and developed for the reduction of wide zygomatic bone. However, the previous methods have several disadvantages, including the following: potential cheek droop, a limited amount of possible volume reduction, an unfavorable contour due to nonunion, and limited inward repositioning of the zygomatic arch. Thus, the authors introduce an effective method to overcome the limitations and disadvantages of other previous reduction malarplasty techniques.

Surgical Management of Scalp Infantile Hemangiomas.

Background: Scalp infantile hemangiomas (IHs) are usually focal lesions that can be both disfiguring and may lead to complications such as ulceration and bleeding. The clinical features of scalp IHs have not been previously studied. This study aims to identify the clinical characteristics associated with scalp IH, the indications for surgical intervention, and results of surgical treatment.

Inverted V-shape Osteotomy with Central Strip Resection: A Simultaneous Narrowing and Vertical Reduction Genioplasty.

Background: In East Asian countries, a prominent, long, and squared contour of the lower third of the face is considered unattractive, strong, and masculine. To change such a facial contour into an ovular contour, correction of the chin area is essential to accomplish the overall curve in the mandibuloplasty, and various methods for the horizontal reduction of the chin area have been suggested. The horizontal osteotomy and central strip resection technique, which is the most widely used method, has comparatively little effect and some restrictions.

Comparison between Z-plasty and V-Y Advancement for the Surgical Correction of Cryptotia.

Background: Cryptotia correction by V-Y advancement of a temporal triangular flap was introduced in 2005. However, despite the several advantages of V-Y advancement, visible scars at the donor site are problematic. As a result, a Z-plasty technique was considered for skin deficiency in mild cases.

Platelet-rich plasma: quantitative assessment of growth factor levels and comparative analysis of activated and inactivated groups.

Background: Platelet-rich plasma (PRP) has more concentrated platelets than normal plasma (approximately 150-400×10(3) cell/dL). Platelets excrete several growth factors and cytokines that are associated with the healing and regeneration process. However, even though PRP is widely used, the mechanism or actual effect is presently unclear.

Effect of amniotic fluid stem cells and amniotic fluid cells on the wound healing process in a white rat model.

Background: Amniotic-fluid-derived stem cells and amniocytes have recently been determined to have wound healing effects, but their mechanism is not yet clearly understood. In this study, the effects of amniotic fluid stem cells and amniocytes on wound healing were investigated through animal experiments.

Methods: On the back of Sprague-Dawley rats, four circular full-thickness skin wounds 2 cm in diameter were created.

Usefulness of Oncoplastic Volume Replacement Techniques after Breast Conserving Surgery in Small to Moderate-sized Breasts.

Background: In Korean women, many of whom have small to moderate-sized breasts, it is difficult to cover a partial breast defect using oncoplastic volume displacement techniques after removal of an adequate volume of tissue during oncologic surgery. In such cases, oncoplastic volume replacement techniques are more useful.

Methods: From January 2007 to December 2011, 104 women underwent a total of 107 breast-conserving surgeries with various kinds of oncoplastic volume replacement techniques.

Surgical techniques for personalized oncoplastic surgery in breast cancer patients with small- to moderate-sized breasts (part 2): volume replacement.

Oncoplastic breast surgery has become a popular choice of treatment for breast reconstruction after mastectomy. There are two different techniques in oncoplastic surgery depending on the volume of the excised breast tissue. One is the volume displacement procedure, which combines resection with a variety of different breast-reshaping and breast-reduction techniques; the other is the volume replacement procedure in which the volume of excised breast tissue is replaced with autologous tissue.

Surgical techniques for personalized oncoplastic surgery in breast cancer patients with small- to moderate-sized breasts (part 1): volume displacement.

Despite the popularity of breast-conserving surgery (BCS), which constitutes 50-60% of all breast cancer surgeries, discussions regarding cosmetic results after BCS are not specifically conducted. The simple conservation of breast tissue is no longer adequate to qualify for BCS completion. The incorporation of oncological and plastic surgery techniques allows for the complete resection of local disease while achieving superior cosmetic outcome.
