[BACKGROUND] Acellular dermal matrix (ADM) is commonly used in implant-based breast reconstruction, but the optimal timing of ADM use in prepectoral two-stage reconstruction remains uncertain. [OBJECTIVES] We evaluated whether delaying ADM…

 Prepectoral direct-to-implant (DTI) is a common implant-based breast reconstruction method used for patients with breast cancer, although patients often present capsular contracture as a common complication. This study aimed to investigate…

[BACKGROUND] Implant-based breast reconstruction has evolved over time. However, the effects of prepectoral breast reconstruction (PBR) compared with those of subpectoral breast reconstruction (SBR) have not been clearly defined. Therefore,…

[INTRODUCTION] Post-mastectomy radiation therapy is an important component of adjuvant therapy for high-risk patients. However, radiation to reconstructed breasts can cause various complications. Recently, hypofractionated (HF) protocols ha…

Deep inferior epigastric perforator (DIEP) flap surgery is a common technique for breast reconstruction. However, the long and noticeable abdominal scar is one of its greatest disadvantages. Here, the authors suggest a minimal scarring DIEP…

 Hyaluronic acid fillers can be manufactured using various processes. They have multiple properties, including their concentration, degree of modification, and rheological data. Cohesion is one such property to evaluate gel integrity; howev…

Potential disruptions in the biocompatibility of hyaluronic acid (HA) fillers can arise with mono-linked 1,4-butanediol diglycidyl ether (BDDE) or unreacted (pendant) 1,4-butanediol di-(propan-2,3-diolyl) ether. Assessing the filler's degre…

Facial massages are frequently performed to achieve a feeling of freshness, rejuvenation, skin tightening, and delayed onset of wrinkles. However, vigorous massages can induce unexpected symptoms. Here, we present a case of a woman who comp…

[BACKGROUND] Sarcopenia is characterized by the loss of skeletal muscle mass and power. Preoperative sarcopenia may be associated with an increased risk of postoperative complications after autologous free-flap breast reconstruction surgery…

Although hyaluronic acid (HA) filler injections are associated with various non-vascular inflammatory complications, the underlying mode of action remains unclear. The hyaluronic acid filler may not be sufficiently pure, leading to an immun…

After genioplasty, the occurrence of bleeding is rare; however, rapid enlargement or displacement of the tongue secondary to lingual or sublingual hematoma can lead to life-threatening airway obstruction, necessitating prompt recognition, a…

[PURPOSE] Lymphovenous anastomosis (LVA) is primarily used for treating early-stage lymphedema. Here, we aimed to investigate the relationship between lymphatic flow velocity and the efficacy of LVA in breast cancer-related lymphedema patie…

[BACKGROUND] Hyaluronic acid filler injection is commonly administered to correct temple hollowness, typically through deep temporal injection. Since the vascular distribution at the injection site can be diverse, studies on avoiding damage…

[BACKGROUND] Hyaluronic acid (HA) filler injection is easy and effective for augmenting the temple. However, there are multiple layers in the temple and multiple guidelines regarding the optimal layer for administering these fillers. In thi…

[BACKGROUND] Owing to the increase in the number of medical procedures performed every year, the frequency of filler injection-related complications has also increased. Although slow, gentle injections with low pressure are usually consider…

[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. […

[BACKGROUND] Deviated noses and asymmetric nostrils can be corrected using corrective rhinoplasty. However, after proper correction, adjacent facial mimetic muscles can cause recurrence of asymmetry because of preoperative habits. [OBJECTI…

[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] Soft tissue filler is commonly used for facial contouring. However, incorrect use can lead to severe ocular complications. Even though filler injections are quite different from fat grafts, they are considered similar procedure…

[BACKGROUND] Soft-tissue necrosis caused by vascular compromise is a frequent and troublesome complication of hyaluronic acid filler injection. Hyaluronidase has been proposed as a treatment for this condition. This study aimed to determine…

[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…

[BACKGROUND] Blindness caused by soft-tissue filler injection is the most tragic complication, with no standard treatments until recently. Retrobulbar hyaluronidase injection has been proposed as the treatment, but its effectiveness in visu…

[BACKGROUND] Soft tissue filler injection is a common procedure for augmentation rhinoplasty. Various techniques for augmenting the nasal dorsum using a soft tissue filler have been attempted considering the size of the needle, the anatomic…
