[BACKGROUND] Poly-L-lactic acid (PLLA) is widely used in tissue engineering. The natural polymer hyaluronic acid (HA) shows excellent biocompatibility and affects cell signaling, proliferation, and differentiation. In addition, a polynucleo…

[BACKGROUND] A wide lower face and a square jaw are considered esthetic problems, particularly in Asia. [OBJECTIVE] To investigate the optimal dose of a novel botulinum toxin (prabotulinum toxin A) for treating masseteric hypertrophy. [ME…

The safe and effective dosing of botulinum neurotoxins (BoNTs) requires accurate and reliable methods to measure their potency. Several novel methods have been introduced over the past decade; however, only few studies have compared the pot…

[BACKGROUND] Inflammation, a vital immune response to infection and injury, is mediated by macrophage activation. While spleen tyrosine kinase (Syk) and myeloid differentiation primary response 88 (MyD88) are reportedly involved in inflamma…

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…

It is allegedly reported that the BellaGel SmoothFine (HansBiomed Co. Ltd., Seoul, Korea) and Motiva Ergonomix (Establishment Labs Holdings Inc., Alajuela, Costa Rica) are representative brands of a microtextured breast implant in Korea. We…

[OBJECTIVES] In extracorporeal septoplasty (ECS), the entire septal cartilage is harvested, and a neo-L strut is built extracorporeally. Thus, ECS can simultaneously achieve septum straightening and tip projection. This study evaluated the …

[BACKGROUND] For revision surgeries due to complications associated with alloplastic materials, autologous tissues including dermofat are considered. However, graft absorption, shaping, and donor site morbidity remain crucial challenges. Th…

[BACKGROUND] Thread rhinoplasty can trigger a reaction to thread material, which is a foreign body. We compared clinical features induced by absorbable and non-absorbable threads following thread rhinoplasty. [CASE SUMMARY] Two patients wh…

[BACKGROUND] Korea is no longer safe from the risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL); the first reported case was a Korean woman in her 40s who had a 7-year-history of receiving an implant-based augmenta…

[BACKGROUND] Immediate breast reconstruction with implant (IBRI) can produce good aesthetic results after nipple-sparing mastectomy (NSM). Various surgical incisions can be used for NSM. The purpose of this study is to compare outcomes of u…

[BACKGROUND] In microvascular anastomosis, size discrepancy is common and can increase thrombotic complications. If size differences can be predicted, then vessels of the appropriate size can be selected. This study documented the differenc…

HA (Hyaluronic acid) filler, the most commonly used dermal filler, causes several side effects. HA-PN (Hyaluronic acid-Polynucleotide), a new composite filler, has excellent biocompatibility and induces tissue regeneration. In this study, w…

[BACKGROUND] Although fat grafting has become a widely used technique in aesthetic and reconstructive surgeries, resorption is still a challenge. Micronized acellular dermal matrix (ADM) has been considered as a stable, biocompatible soft t…

[BACKGROUND] We investigated RNA sequencing-based transcriptome profiling and the transformation of mature osteoblasts into bone lining cells (BLCs) through a lineage tracing study to better understand the effect of mechanical unloading on …

Aptamers are biomaterials that bind to a target molecule through a unique structure, and have high applicability in the diagnostic and medical fields. To effectively utilize aptamers, it is important to analyze the structure of the aptamer …

This study aimed to investigate the efficacy of the transplantation of autologous adipose-derived stromal vascular fraction (AD-SVF) containing adipose stem cells (ASCs) in regenerating functional endometrium in patients with severe Asherma…

[INTRODUCTION] Stroke often causes residual hemiparesis, and upper extremity motor impairment is usually more disabling than lower extremity in those who are suffering from post-stroke hemiparesis. Cell therapy is one of the promising thera…

[BACKGROUND] Implant-based dual-plane augmentation mammoplasty requires accurate separation of the pectoralis major muscle (PMM) at its origins. The authors identified the PMM origins during breast reconstruction surgery with the goal of pr…

[INTRODUCTION] Breast filler injections are less commonly used due to their associated complications, such as pain and foreign body reactions. Yet, these fillers are often administered illegally, resulting in aesthetic or life-threatening c…

[BACKGROUND] Rhinoplasty is one of the most commonly performed cosmetic surgery procedures. Most Asians desire elevation of their relatively flat nasal dorsum and tip to make them appear more prominent. This study introduces a simple method…

[BACKGROUND] Due to the anatomical complexity of the deep temporal fascia (DTF), practical guidelines for its safe harvest are lacking. However, since the upper temporal compartment (UTC) contains no vital structures, it may provide safe ac…

The facelift is one of the most popular cosmetic surgery methods of antiaging. There are many complications in facelift, but infections rarely occur relatively. The authors would like to introduce a patient who developed infection after a f…
