[BACKGROUND] Effective skull base reconstruction for huge cranial-nasal defects is critical to restoring function and esthetics and preventing complications, such as cerebrospinal fluid (CSF) leakage and ascending infection. We introduced a…

Professor Chung, an Emeritus Professor at Hanyang University School of Medicine, was a pioneering figure in Korean neurosurgery. After serving as an Army Surgeon during the Korean War, he specialized in neurosurgery, training under Professo…

[BACKGROUND] There is inadequate evidence for the utilization of nonnarcotic pain medications for postoperative pain management following rhinoplasty. [OBJECTIVE] To compare the effectiveness of opioid and non-opioid medications for postop…

[BACKGROUND] Facial asymmetry is often overlooked in evaluations of nasal function and aesthetics, despite its potential impact on assessments in facial plastic surgery. [OBJECTIVE] This study aims to utilize AI tools to identify facial as…

Despite the remarkable advances of dermal fillers that reduce wrinkles caused by dermis thickness reduction, they still lack effective hydrogel systems that stimulate collagen generation along with injection convenience. Here, we develop a …

[INTRODUCTION] We occasionally encounter irregular marginated masses discovered incidentally in young individuals. In most cases, further investigations are conducted to assess the presence of a primary malignancy, as these masses often rai…

[BACKGROUND] Patient satisfaction is an essential outcome measure after a rhinoplasty. Yet it is not known whether the opinions of rhinoplasty patients and surgeons on nasal aesthetic appearance differ. [OBJECTIVES] The aim of this study w…

[OBJECTIVES] Our aim in this study was to investigate if we could predict perforator localization during ALTF elevation, using information from acoustic Doppler (AD) and computed tomography angiography (CTA). [METHODS] Prospective observat…

Photodocumentation is an essential part of a rhinoplasty surgeon's practice. Preoperative photographs are an indispensable device for patient counseling and surgical planning. Comparison of preoperative and postoperative photographs allow f…

[BACKGROUND] Among the materials used for dorsal augmentation rhinoplasty (DAR), cross-linked human acellular dermal matrix (ADM) has been claimed for its low risk of infection and extrusion. The aim of this study was to compare the effecti…

Deep inferior epigastric artery perforator (DIEP) flap surgery is one of the most common techniques for breast reconstruction using abdominal tissue. Although the DIEP flap reduces donor-site morbidity when compared with the conventional fr…

[BACKGROUND] Galeal or temporalis muscle flaps have been traditionally used to reconstruct skull base defects after tumor removal. Unfortunately, these flaps do not provide sufficient vascularized tissue for a dural seal in extensive defect…

[BACKGROUD] Outcomes of traditional treatment for osteonecrosis of the femoral head (ONFH) are not always satisfactory. Hence, cell-supplementation therapy has been attempted to facilitate necrotic-tissue regeneration. Adipose-derived mesen…

Epidermal or epidermoid cysts are one of the most frequent benign masses at the subepidermal level. They are typically smooth, movable, and fluctuant masses covered with stratified squamous epithelium. They rarely grow to a huge size, and o…

A subciliary incision has been widely used not only for blepharoplasty but also for facial fracture surgery. However, lower eyelid malpositioning is one of the most common complications after fracture surgery. A limited number of studies ha…

Although many graft materials have been used for augmentation rhinoplasty, an ideal graft has not yet been developed. As the field of tissue engineering has been developing, it has been applied to the reconstruction of many organs, but its …

Homologous graft materials for dorsal augmentation are safe and biocompatible with a low risk of complications. Acellular dermal matrix (ADM) provides natural appearance of the nose and long-term structural integrity without extrusion, show…

Cells migrate by directing Ras-related C3 botulinum toxin substrate 1 (Rac1) and cell division control protein 42 (Cdc42) activities and by polymerizing actin toward the leading edge of the cell. Previous studies have proposed that this pol…

[BACKGROUND] Breast augmentation by cell-assisted lipotransfer (CAL) may achieve a more natural breast contour than silicone implants. Moreover, certain complications associated with these prosthetic devices can be avoided with CAL. Few pro…

[INTRODUCTION] One of the most serious complications of breast reconstruction and augmentation using silicone implants is capsular contracture. Several preventive treatments, including vitamin E, steroids, antibiotics, and cysteinyl leukotr…

[BACKGROUND] We postulated that the fibrotic capsule around a silicone implant could be induced by ischemic conditions, based on previous reports that hypoxia is an important microenvironmental factor in the development of tissue fibrosis. …

[UNLABELLED] In 162 Asian patients, primary breast augmentation was performed by a single surgeon during 5 years. The purpose of this study evaluates Asian outcomes in primary breast augmentation using single antibiotic breast irrigation by…

[BACKGROUND] Dorsal augmentation is the most commonly performed procedure in rhinoplasty for Asian patients. Due to the anatomic features of the Asian nose, the use of nonautologous materials to obtain a proper degree of augmentation is ine…

[BACKGROUND] To achieve the desired refinements in Asian patients, sufficient septal cartilage is needed for ideal tip projection and lengthening of the nose by the septal extension supported by the stable septum. There are many cases of in…

[OBJECTIVE] This paper aims to study whether immediate re-insertion of non-autologous augmentation material in revision augmentation rhinoplasty is a safe surgical strategy creating a successful and functional aesthetic outcome. [STUDY DES…

As there is no single ideal material for dorsal augmentation in rhinoplasty, there has been a continuing need for the development of improved materials. Therefore, we aimed to evaluate the outcome of using a novel tissue-engineered construc…

The role of three-dimensional (3D) printing has expanded in diverse areas in medicine. As plastic surgery needs to fulfill the different demands from diverse individuals, the applications of tailored 3D printing will become indispensable. I…

[BACKGROUND] Robot-assisted neck dissection in patients with head and neck cancer has been demonstrated to be feasible. We conceived a surgical technique of surgery for parotid cancer with the robotic system via a gasless modified facelift …

[BACKGROUND] The septal cartilage is the most useful donor site for autologous cartilage graft material in rhinoplasty. For successful nasal surgery, it is necessary to understand the developmental process of the nasal septum and to predict…
