[BACKGROUND] The infraorbital region is one of the most complex and esthetically critical areas of the face. Age-related changes, such as infraorbital groove and infraorbital fat bulging, frequently coexist and vary significantly among indi…

This study evaluated whether echogenic needles improve ultrasound visibility during hyaluronic acid filler injections in the cheek-a high-risk area due to anatomical variability of facial vessels. In a single-patient in vivo setting, 3 type…

Selective chemodenervation of the inferior gluteus maximus (GMax) may induce compensatory hypertrophy of its superior fibers. Two healthy female subjects underwent ultrasound-guided botulinumtoxinA (JETEMA THE TOXIN, JETEMA Co., Ltd., Korea…

[BACKGROUND] Among various filler products designed to improve facial wrinkles, those using biodegradable polymer microspheres have gained attention. Recently, a filler composed of porous polycaprolactone (PCL) microspheres was introduced. …

[BACKGROUND] Botulinum toxin is a key treatment for dynamic wrinkles. [OBJECTIVE] This study evaluates CKDB-501A, a botulinum toxin completely free from animal-derived components including human-serum albumin, comparing its efficacy and sa…

[INTRODUCTION] Osteotomies are routinely incorporated in rhinoplasty, however, the influence of mass, velocity, kinetic energy (KE), and momentum (p) of the mallet on fracture patterns has not been studied. [METHODS] An experimental sledge…

This study aimed to analyze cases of anterolateral thigh (ALT) free flap used for hand reconstruction with terminal perforator-to-digital artery anastomosis. Patients who underwent ALT free flap placement with terminal perforator-to-digital…

In general, the nerve cells of the peripheral nervous system regenerate normally within a certain period after the physical damage of their axon. However, when peripheral nerves are transected by trauma or tissue extraction for cancer treat…

[OBJECTIVE] In the esthetic field, the masseter muscle is commonly targeted by botulinum neurotoxin for facial contouring. However, multiple botulinum neurotoxin injections have been reported to cause muscle fibrosis. Ultrasonography can be…

Masseter are commonly botulinum neurotoxin targeted muscle for facial contouring in aesthetic field. However, paradoxical masseteric bulging is common adverse effect that has not been discussed with ultrasonographic observations. Retrospect…

[BACKGROUND] Lip augmentation procedure with hyaluronic acid (HA) fillers can make patients younger with more attractive. After the injection on the lips, the result is temporary. Physicians and patients wonder how long the HA filler last o…

[BACKGROUND] Successful aesthetic interventions in upper-face aging require a profound understanding of the intricate anatomy of temporal. This study aimed to comprehensively evaluate the effect of hyaluronic acid (HA) injection in temple a…

[BACKGROUND] As lip enhancement with fillers has grown in popularity, practitioners have sought to identify injection methods that achieve aesthetically pleasing results while avoiding adverse events such as arterial injury due to intravasc…

Botulinum toxin can be used for various purposes to enhance neck aesthetics, addressing concerns such as platysmal bands, optimizing the cervicomental angle, preventing worsening of horizontal neckline and decolletage lines during aging, su…

[PURPOSE] We aimed to demonstrate non-inferiority in terms of functional outcomes in patients with lumbar spinal stenosis who underwent full-endoscopic decompression compared with tubular-based microscopic decompression. [METHODS] This pro…

[BACKGROUND] With the use of sonography, soft-tissue thickness can be measured accurately to assess the volumizing effects of fillers. [METHODS] In this prospective study, monophasic stabilized hyaluronic acid filler (1 cc) was injected in…

[BACKGROUND] Single free flaps are a commonly used reconstructive method for multiple soft tissue defects in digits. We analyzed the flap size, division timing, and degree of necrosis in cases with various types of flap division. [METHODS]…

[PURPOSE] The hand has unique skin characteristics. Intrinsic flap donors are limited due to functional specificity and compactly connected structures. The hypothenar area is a reliable option for the reconstruction of finger defects. We pe…

[OBJECTIVE] This study aims to investigate the efficacy of botulinum toxin type A (BTX-A) in the prophylactic management of vestibular migraine (VM) and to determine whether this treatment modulates intrinsic functional brain network. [MET…

Open rhinoseptoplasty has been widely performed in the field of otorhinolaryngology. However, from the perspective of beginners, rhinoseptoplasty is a hard-to-learn surgery that involves a relatively steep learning curve. Therefore, practic…

[OBJECTIVE] Many rhinoplasty techniques, including dorsum augmentation and tip surgery, could be performed under conscious sedation rather than general anesthesia. However, as osteotomy is an invasive procedure, it is burdensome for surgeon…

Fingertip injuries occur commonly owing to trauma in everyday life. Performing amputation or stump revision for a fingertip injury can make it possible to quickly return to daily life, but causes functional and cosmetic problems. We believe…

[BACKGROUND] Injection of hyaluronic acid filler, a common procedure for nasolabial fold correction, poses a risk of vascular compromise, which can result in skin necrosis and blindness. [OBJECTIVES] The aim of this study was to examine th…

[BACKGROUND] Glabellar wrinkle corrections are usually performed by injecting botulinum toxin and hyaluronic acid fillers. The glabella is one of the most dangerous locations for filler injection because of possible visual complications. […

[PURPOSE] To describe postoperative management following ablative carbon dioxide laser resurfacing of the lower eyelids. [METHODS] A retrospective review of patients who consecutively underwent bilateral lower eyelid ablative carbon dioxid…

[OBJECTIVES] Although lateral osteotomy is an important part of rhinoplasty, it is known to be closely associated with postoperative eyelid edema and ecchymosis after rhinoplasty. There is no consensus on which osteotomy methods are effecti…

[BACKGROUND] Despite its relative rarity, the potential for loss of productive years makes aneurysmal subarachnoid hemorrhage (SAH) a considerably important entity in young adult patients (20-39 years of age). This study aimed to analyze ou…

[BACKGROUND] For volar soft tissue defects of the proximal interphalangeal (PIP) joint, free flaps are technically challenging, but have more esthetic and functional advantages than local or distant flaps. In this study, we compared the lon…

[BACKGROUND] The introduction of the partial second toe pulp free flap has enabled superior aesthetic and functional results for fingertip reconstruction in adults. Children undergoing fingertip amputation for various reasons have limited o…
