[BACKGROUND] Nasolabial folds (NLFs) are a common cosmetic concern. Hyaluronic acid (HA)-based fillers are increasingly popular for minimally invasive facial wrinkle and fold correction. This study aimed to evaluate the efficacy and safety …

[BACKGROUND] Hyaluronic acid (HA) dermal fillers are widely used as a nonsurgical treatment for facial aging, including nasolabial folds (NLFs). Because demand for convenient aesthetic procedures increases, new HA products require rigorous …

[BACKGROUND] Capsular contracture is a common complication following implant-based breast reconstruction. Current assessment methods, primarily relying on the subjective Baker grading system, lack objectivity and quantitative data, which hi…

[PURPOSE] Several types of dermal fillers have been recently introduced and used for penile augmentation (PA). However, few studies have compared outcomes after the injection of different fillers. This study aimed to compare the clinical ou…

The facial nerve is the seventh cranial nerve, and its temporal branch (TBFN) innervates the frontalis muscle. Peripheral nerve disorders involving the facial nerve can lead to facial palsy, for which a common non-invasive treatment approac…

[BACKGROUND] Implant-based breast reconstruction is associated with increased risk of early infection and late-stage capsular contracture. [OBJECTIVES] We evaluated the feasibility of a dual drug-releasing patch that enabled the controlled…

[OBJECTIVE] The aim of this study was to understand the temporal and spatial distribution of canonical endochondral ossification (CEO) and non-canonical endochondral ossification (NCEO) of the normal growing rat condyle, and to evaluate the…

[BACKGROUND] A face-lift or rhytidectomy is the procedure most directly associated with rejuvenation. There are several surgical techniques for face-lifts, but criteria for the selection of techniques, based on the patient's face shape, are…

This study aimed to develop and validate a machine learning (ML)-based model for predicting liposuction volumes in patients with obesity. This study used longitudinal cohort data from 2018 to 2023 from five nationwide centers affiliated wit…

Finger injuries caused by green onion cutting machines in Korean kitchens have unique characteristics of an incomplete amputation in which multiple parallel soft tissues and blood vessels are injured in the same form. In this study, we aime…

[BACKGROUND] Rhabdomyolysis is a potentially fatal clinical syndrome resulting from the damage or breakdown of skeletal muscle, which can also lead to permanent disabilities. Based on our review of studies on rhabdomyolysis after prolonged …

Currently, dermal fillers are largely based on commercialized cross-linked hyaluronic acid (HA) injections, which require a large injection force. Additionally, HA can be easily decomposed by enzymes, and HA-treated tissues present a risk o…

Lumbar central spinal stenosis (LCSS) is a common disorder that causes disability and pain in the elderly. It causes pain in the radicular leg. Recently, transforaminal epidural steroid injection (TFESI) has been widely used to control radi…

[BACKGROUND] Inferior implant malposition after breast augmentation is the second most common reason for revision surgery. This article introduces the new concept of dual-plane pocket formation in transaxillary breast augmentation to preven…

[BACKGROUND] In secondary nasal tip plasty, it is often difficult to harvest appropriate septal extension grafts for sufficient tip projection. Therefore, studies using numerous alloplastic materials in rhinoplasty have been reported. This …

[INTRODUCTION] Endoscopically assisted malarplasty with a greenstick fracture is a method for preserving the body eminence and improving arch protrusion. However, this technique is inadequate when malar body reduction is required. To compen…

The purpose of this study was to determine and compare the effects between injecting botulinum toxin A (BTX-A) transconjunctivally into the palpebral lobe and transcutaneously into the orbital lobe of the lacrimal gland in patients with epi…

Botulinum toxin (BoNT) injection is widely used to improve spasticity. However, after the treatment, the patient may experience pain, inflammation, swelling and redness at the injection site. In this case, we addressed deep vein thrombosis …

[OBJECTIVE] To detect signals of potential adverse events (AEs) after botulinum toxin (BTX) treatment using the Korea Institute of Drug Safety & Risk Management-Korea adverse event reporting system database (KIDS-KD). [MATERIALS AND METHOD…

Predictive factors associated with postoperative mortality have not been extensively studied in plastic and reconstructive surgery. Neutrophil-lymphocyte ratio (NLR), a systemic inflammation index, has been shown to have a predictive value …

[BACKGROUND] Transoral robotic surgery (TORS) has recently emerged as a surgical technique for oropharyngeal cancer. We performed a systematic review to investigate the clinical safety and effectiveness of robotic surgery compared with conv…

: The intramuscular nerve distribution in the extraocular muscles is important for understanding their function. This study aimed to determine the intramuscular nerve distribution of the oculomotor nerve within the inferior oblique muscle (…

[BACKGROUND] Botulinum toxin (BTX) is widely used for pain control in various musculoskeletal disorders. [OBJECTIVES] We evaluated the analgesic effect of botulinum toxin type A (BTX-A) in chronic lateral epicondylitis and compared the eff…

[PURPOSE] Knowledge of the distribution of intramuscular nerves of the extraocular muscles is crucial for understanding their function. The purpose of this study was to elucidate the intramuscular distribution of the oculomotor nerve within…

Hyaluronic acid (HA) is widely used in medicine, especially for contouring or volumizing soft tissue and intra-articular injection. However, it is not well known that HA injection can cause life-threatening pulmonary complications. We recen…

The purpose of this study was to investigate the relationship between masticatory muscular hypotrophy and mandibular growth in juvenile nonhuman primates (cynolmolgus monkeys, Macaca fasicularis). We hypothesized that botulinum toxin (BTX)-…

[OBJECTIVE] The purpose of this study was to investigate changes in the dentoalveolus and occlusal plane associated with the hypotrophy of unilateral masticatory muscles following botulinum toxin (BTX) treatment in the juvenile period of ra…

[BACKGROUND] Multiple approaches for nipple reconstruction exist, and none is considered superior to all others. The star flap is one of the most popular methods for nipple reconstruction, but gradual height loss is a major concern. We pres…
