[BACKGROUND] Energy-based devices (EBDs), such as high-intensity focused ultrasound, radiofrequency, and microwave, are increasingly used for facial rejuvenation, raising concerns about whether heat exposure may affect the potency of botuli…

[BACKGROUND] Botulinum neurotoxin type A (BoNTA) is widely used in aesthetic facial rejuvenation medicine. The exponential growth in using BoNTA for cosmetic purposes in Korea necessitates an update to the existing practice guidelines, buil…

[PURPOSE] This study investigates the global reach of two novel, interactive, online, and free courses entitled "Basics of Oculoplastic Surgery" (BOS) and "Intermediate Oculoplastic Surgery" (IOS) and assesses how effectively they enhanced …

[BACKGROUND] Assessing the methodologic and reporting quality of randomized controlled trials (RCTs) in plastic surgery is crucial in maintaining the standards of evidence-based practice. Previous evaluations underscored deficiencies in rep…

The multiple wavelength diode laser (MWDL) is a sophisticated device designed to target deeper skin layers by emitting various wavelengths. Its unique feature is the ability to deliver heat to specific depths within the tissue using differe…

[BACKGROUND] Botulinum toxin is a crucial therapeutic tool with broad indications in both cosmetic and medical fields. However, the expanding cosmetic use and increased dosages of botulinum toxin have raised concerns about resistance, makin…

A subzygomatic arch depression creates a bulky face outline. To smoothen these depressions and correct facial contours, hyaluronic acid filler injection methods are frequently used. However, the complexity of the subzygomatic region make it…

[BACKGROUND] Crow's feet are bilateral orbital wrinkles formed by the orbital portion of the orbicularis oculi muscle, which is the target muscle for botulinum neurotoxin (BoNT) injection. [OBJECTIVES] This study's aim was to demonstrate a…

Anatomical studies of the parotid gland are important for mid- and lower face filler, botulinum toxin, and thread lifting procedures. The purpose of this study was to observe the topographic anatomy of the parotid gland using cadaveric diss…

The characteristics of retrograde filling material are important factors that can affect the long-term success of apical microsurgery. Various calcium silicate-based cements (CSC) were introduced to overcome drawbacks of mineral trioxide ag…

[BACKGROUND] Autologous adipose-derived stromal vascular fraction treatments have been shown to elicit antiinflammatory, antifibrotic, immunomodulatory, angiogenic, and regenerative effects. Injections of adipose-derived stromal vascular fr…

[BACKGROUND] Blepharoplasty alone cannot completely correct deep infraorbital grooves because of its limited ability to improve anatomical volume loss. As the concept of resolving periorbital fat atrophy to improve the infraorbital groove w…

[BACKGROUND] The infraorbital groove can be corrected by lower blepharoplasty, microfat grafting, and soft tissue filler injection. Recently, multiple twisted polydioxanone threads were developed for facial rejuvenation. [OBJECTIVE] This s…

During dual plane breast augmentation (DPBA), the costal origin of the pectoralis major (the PM) should be cut to ensure appropriate coverage and positioning of an implant. However, surgeons sometimes make inappropriate planar incisions and…

[BACKGROUND] This study introduces a central pedicle reduction mammaplasty with a vertical scar technique. [OBJECTIVES] This study is aimed to create a more conical breast shape and long-lasting better projection by modifying reduction mam…

[BACKGROUND] The ideal timing of postmastectomy radiation therapy (PMRT) in the setting of two-stage implant-based breast reconstruction remains unclear. In this cohort study, the authors sought to determine whether complication rates diffe…

We experienced a patient of subcondylar fracture who had a squared contour of the lower face with prominent angle of the mandible and masseter hypertrophy. Our patient was increasingly seeking esthetic improvement of the lower third of the …

[PURPOSE] The number of programs offering hand surgery fellowships has remained approximately the same over a 6-year period while the number of fellows within these programs has decreased by 46%. This study aimed to identify factors that pe…

The authors evaluated existing and new criteria for defining the medical necessity for breast reduction surgery. Two cohorts of women (those requesting breast reduction surgery [N = 266] and a group of controls [N = 184]) completed a questi…

Studies published in the medical literature often neglect to consider the statistical power needed to detect a meaningful difference between study groups. Small sample sizes tend to produce negative results because of low statistical power.…
