研究室紹介
Professor Dong Eun-sang's research lab specializes in facial and craniofacial reconstruction, with a strong focus on rhinoplasty, septoplasty, and orbital floor fracture repair. The lab investigates innovative surgical techniques—particularly endoscopic and transnasal approaches—for improved outcomes in nasal and orbital trauma. Key research directions include optimizing graft survival in soft tissue augmentation using adipose-derived stem cells and evaluating biocompatible, absorbable materials for orbital reconstruction. The lab emphasizes minimally invasive, endoscopic-guided procedures to enhance precision and reduce complications.

15Purpose: As the use of computed tomographic scanning spread, the diagnosis of blow-out fractures of the medial orbital wall increased. Conventionally, the surgery of blow-out fractures in medial orbital wall was performed by various approaches with external incision or endoscopic approach. Although the field of orbital surgery has progressed significantly during the last decade, accurate realignment and replacement of component is difficult due to lack of visualization of the fracture site, blin
Background Absorbable materials offer many advantages in the reconstruction of orbital walls; however, the possibility of postoperative enophthalmos after complete absorption cannot be excluded. We evaluated the postoperative results of absorbable mesh plates used as onlay implanting on the medial orbital wall to determine whether they are suitable for medial orbital wall reconstruction. Methods The study included 20 patients with medial orbital wall fractures who were followed up for more than
Purpose: Most of nasal bone fractures involve the septum; either or both of the ethmoidal perpendicular plate(EPP) and quadrangular cartilage(QC). Unlocked tension from the underlying quadrangular cartilage and poorly reduced bony septum are obstacles to the successful reduction of nasal bone. So we compared the preliminary outcome of septoplasty as a primary treatment with the untreated septum in nasal bone fractures. Methods: We performed a retrospective study of 215 patients who underwent red
Purpose: For hypertrophic scars and keloids no universally effective treatment modality exists. Surgical revision, intralesional steroid injection, silicone gel sheeting, pressure, laser, and others have been used with variable success, but many treatments are associated with high recurrence rates. Although optimal treatment remains undefined, successful treatment can be obtained through a combined therapeutic approach. Methods: We used three therapeutic modalities in combination, which are intr
Septorhinoplasty in Asians is very challenging in terms of shortage of septal cartilage. Many cases in correction of dorsal and caudal septal deformities requires septal surgery including cartilaginous graft. Septoplasty is a well-known procedure which preserves majority of quadrangular cartilage, however, it is hardly adopted in Asians. The preoperative evaluation is accomplished using nasal endoscopy. The posterior and inferior chondrotomy for septal swinging-door procedure can be performed un
Purpose: A number of flap for nipple reconstruction have been well described in the literature. However, most of these techniques do not permit the reconstruction of a projecting nipple and all are hampered to some extent by long-term loss of nipple projection. The objective of this study is to evaluate the long-term result and clinical efficacy of nipple reconstruction using skate flap technique after breast reconstruction. Methods: A retrospective chart review was carried out on 23 patients wh
Although autologous lipoaspirated fat grafting is now the most commonly used technique for soft tissue augmentation, problems, such as, unpredictability and a low rate of graft survival remain. The purpose of this study was to compare the long-term viabilities of aspirated fat grafts mixed with adipose-derived stem cells (ASCs; the experimental group) and aspirated fat grafts alone (the control group). Autologous aspirated fats were taken from the interscapular area and transplanted under scalp
Dermal fillers are generally accepted as safe and well-tolerable cosmetic tools. However, adverse reactions have been reported in the literature. Here, we present a case of atypical facial filler granuloma and compare its histologic features with those of the classic paraffinoma.
Background The global prevalence of myelomeningocele has been reported to be 0.8–1 per 1,000 live births. Early closure of the defect is considered to be the standard of care. Various surgical methods have been reported, such as primary skin closure, local skin flaps, musculocutaneous flaps, and skin grafts. The aim of this study was to describe the clinical characteristics of myelomeningocele defects and present the surgical outcomes of recent cases of myelomeningocele at our institution. Metho
Background Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT) evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration. Meth
Background Partially resecting ribs of the recipient site to facilitate easy anastomosis of the internal mammary vessels to free flaps during breast reconstruction can cause chest wall pain or deformities. To avoid this, the intercostal perforating branches of the internal mammary vessels can be used for anastomosis. The purpose of this study was to investigate the location and size of the internal mammary perforator vessels based on clinical intraoperative findings and to determine their reliab
Complete division of transverse carpal ligament (TCL) is accepted as a standard procedure for carpal tunnel syndrome (CTS). In some cases however, after complete release of TCL, the loss of grip and pinch power occurs frequently. Previous study revealed that normal intracanal pressure is 25-30mmHg, therefore There were the possibility that complete division of TCL is an over-correction for CTS. The purpose of this experiment was to measure the carpal tunnel pressure during the incremental divisi
Several imaging methods are helpful in the diagnosis of carpal tunnel syndrome and they are, for example, traditional X-ray, CT and MRI, etc. CT and MRI have their advantage in direct visualization of structural abnormality of the carpal tunnel and median nerve, but these two modalities are expensive and take much time. Recently, high resolution ultrasonography has been reported to be effective in the study of musculoskeletal system. We designed a case control study to assess the diagnostic valu
Purpose: Adipose-derived stromal cells (ASCs) are readily harvested from lipoaspirated tissue or subcutaneous adipose tissue fragments. The stromal vascular fraction (SVF) is a heterogeneous set of cell populations that surround and support adipose tissue, which includes the stromal cells, ASCs, that have the ability to differentiate into cells of several lineages and contains cells from the microvasculature. The mechanisms that drive the ASCs into the osteoblast lineage are still not clear, but
