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. Therefore, this(More)
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(More)
In this report, the authors introduce a rare complication after reduction malarplasty in a 21-year-old male patient. The patient underwent two-jaw surgery and reduction malarplasty at a local plastic surgery clinic in December 2012. He presented with mass-like swelling of the left temporomandibular joint (TMJ) and a clicking sound with jaw movement that(More)
Mandibular angle reduction surgery is widely used for aesthetic purposes. Because inferior alveolar nerve injury is a common complication of this surgery, the anatomical location of this nerve must be known before surgery. This study investigated the relative location of the inferior alveolar nerve in mesofacial and brachyfacial groups. Panoramic views of(More)
BACKGROUND This article presents long-term outcomes after correcting secondary bilateral cleft lip nasal deformities using a refined reverse-U incision and V-Y plasty or in combination with a composite graft in order to elongate the short columella. METHODS A total of forty-six patients underwent surgery between September 1996 and December 2008. The age(More)
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(More)
BACKGROUND The Klippel-Trenaunay syndrome (KTS) is characterized by three clinical features, namely cutaneous capillary malformations, venous malformations, and soft tissue and/or bony hypertrophy of the extremities. The varied manifestations are attributed to the unpredictable clinical nature and prognosis of the syndrome. To elucidate the clinical(More)
BACKGROUND Hypospadias is the most common congenital malformation of the male urinary tract, wherein the urethral opening is located proximal to the normal site. Tubularized incised-plate urethroplasty reconstruction, and its efficacy, remains controversial due to the high recurrence rate. This study aimed to evaluate the results of dartos fascia-reinforced(More)
BACKGROUND Breast-conserving surgery is widely accepted as an appropriate method in breast cancer, and the lateral thoracodorsal flap provides a simple, reliable technique, especially when a mass is located in the lateral breast. This study describes the usefulness of a lateral thoracodorsal flap after breast conserving surgery in laterally located breast(More)
BACKGROUND We conducted this study to analyze the values of the key cephalometric angular measurements of the mandible using 3-dimensional (3D) computed tomography scans. METHODS In the 106 enrolled patients, a 3D cephalometric analysis was performed to measure the angular variables of the mandible. These values were compared between the two sides and(More)
