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 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 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)
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 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)
Distraction osteogenesis (DO) is a less daunting procedure than extensive cranial vault remodeling and has been used to correct sagittal craniosynostosis. The purposes of this study are to describe DO in combination with expansion and compression procedures and to report analytic results based on the cranial index (CI), volumetric measurement, and(More)
BACKGROUND Reduction malarplasty to correct prominent malar complex is popular in Asians. Despite the popularity of reduction malarplasty, most of the surgical methods applied are not selected according to the degree of zygoma protrusion. In this study, we analyzed the effectiveness of two different surgical procedures to clarify their appropriateness for(More)
We have introduced a less invasive, simple, and effective method for zygomatic fractures using percutaneous reduction with a Steinmann pin (S-pin) and temporary external suspension with a Kirschner wire (K-wire).For 2 years, 51 patients underwent first percutaneous reductions and then fixations, which is a method that we developed. After the S-pin no. 1 was(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)
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)
