BACKGROUND Adipose-derived stem cells (ASCs) have positive effects in the wound healing process. OBJECTIVE To clarify whether ASCs positively mitigate scar formation in the wound remodeling process. MATERIALS AND METHODS Full-thickness skin defects were created on the dorsal skin of Yorkshire pigs. After the defects were transformed into early scars,(More)
BACKGROUND We performed robot-assisted neck dissection (RAND) via a modified face-lift (MFLA) or retroauricular approach for neck management and carried out free flap reconstruction via these approaches in patients with head and neck cancer. We assessed the feasibility of free flap reconstruction in patients who had undergone transoral resection of a(More)
As the survival rate of tongue cancer has increased, longer-term results of tongue reconstruction are also being considered. The aim of this study was to report the long-term outcomes of total glossectomy.Of 14 patients who underwent total glossectomy, 11 were reconstructed with the rectus abdominis musculocutaneous free flap and 3 with the anterolateral(More)
BACKGROUND For patients with full thickness skin defects, autologous Split-thickness skin grafts (STSG) are generally regarded as the mainstay of treatment. However, skin grafts have some limitations, including undesirable outcomes resulting from scars, poor elasticity, and limitations in joint movement due to contractures. In this study, we present(More)
BACKGROUND Hair transplantation has been a highly effective technique in reducing wide foreheads and recontouring the hairline. OBJECTIVE To classify hairline contour in Asian women and to find a way to make an ideal and refined female hairline. MATERIALS & METHODS The hairline contours of 234 female volunteers were classified into five groups. We(More)
In many cases, Asians' noses are shorter; their nasal tips have a bulbous shape and typically lack the projection. To correct these problems, we completely dissected the alar cartilage in a three-dimensional manner by which the alar cartilage could be repositioned. Thus, no external force was exerted to the alar cartilage. For approximately 4 years, a total(More)
BACKGROUND Composite grafts are suitable for facial reconstruction because of good color matching, low donor-site morbidity, acceptable texture, and easy surgical techniques. However, their use is limited to small defects and by unpredictable survival rates. As platelet-rich plasma contains large numbers of growth factors and has been widely used for tissue(More)
BACKGROUND Robots have allowed head and neck surgeons to extirpate oropharyngeal tumors safely without the need for lip-split incision or mandibulotomy. Using robots in oropharyngeal reconstruction is new but essential for oropharyngeal defects that result from robotic tumor excision. We report our experience with robotic free-flap reconstruction of head(More)
BACKGROUND/PURPOSE To objectively describe skin color, the Commission International d'Eclairage (CIE) L*a*b* color coordinates and melanin and erythema indexes are used. However, it was difficult to understand the relationship among these parameters and to convert them into each other. We introduced a new technique to measure L*a*b* color coordinates and(More)
Although there are many reports on the measurement of the paranasal sinuses, few studies examined the development of frontal sinus with three-dimensional computed tomography (CT), especially in children. In this study, we evaluated the normal development of frontal sinus in Asian children, and we also analyzed the height, length, and width of the frontal(More)
