Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is the sentinel implant-associated malignancy, illustrating how long-lived biomaterials can reshape local tissue-immune ecology. Although textured (high-surface-area) impla…

[BACKGROUND] The deep inferior epigastric perforator (DIEP) flap is widely used in autologous breast reconstruction, with its success heavily reliant on the vascular anatomy, particularly midline crossing-over vessels that facilitate contra…

[BACKGROUND] Trapezius hypertrophy is a significant aesthetic concern among women. Botulinum toxin has emerged as a potential treatment option for this condition. In this study, we conducted a prospective, randomized, double-blind trial to …

Up to 16.6% of facial lacerations involve the eyebrows, and regional scarring often results in hair loss known as cicatricial alopecia (CA). Secondary CA following eyebrow lacerations is often irreversible, resulting in poor aesthetic outco…

Microfocused ultrasound (MFU) and (MRF) are non-invasive modalities widely used for skin rejuvenation and are often combined with injectables, including neuromodulators and soft tissue fillers. However, large-scale, long-term safety data on…

Recently, various biocompatible and biodegradable materials have garnered significant attention as cosmetic fillers for skin rejuvenation. Among these, poly ε-caprolactone (PCL), poly L-lactic acid (PLLA), poly D,L-lactic acid (PDLLA), and …

Eyelid laxity is a visible sign of aging that can significantly affect appearance and comfort; however, many patients remain reluctant to undergo surgical blepharoplasty. Monopolar radiofrequency (RF) offers a non-invasive alternative. This…

[BACKGROUND] Ultrafine dicing, which reduces cartilage particles to less than 0.2 mm, has gained attention for producing dense implants with reduced distortion. However, concerns about long-term viability and cell damage because of extensiv…

Mixed heritage faces have long been celebrated for their beauty, but there is limited data on the nasal characteristics of these faces. We aim to quantitatively compare nasal geometry across ethnicities and sexes to test the hypothesis that…

[BACKGROUND] In breast reconstruction, arterial coupling has been reported to be more favorable in the thoracodorsal artery (TDA) than the internal mammary artery (IMA). This technique may help overcome anastomosis in a small, deep space. U…

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…

This study proposes a new and simple process that improves the quality of a hyaluronic acid (HA) filler crosslinked with 1,4-butanediol diglycidyl ether (BDDE) using solution dispersion at a low temperature. This process involves the solven…

[BACKGROUND] Intrathecal baclofen (ITB) therapy, a viable alternative for unsuitable candidates of conventional spasticity medications, is a preferred method of administration over the oral route. Owing to its enhanced bioavailability, ITB …

[PURPOSE] Ventral hernias are a common complication of laparotomy, posing challenges particularly when primary fascial closure is unattainable. Although chemical component separation using preoperative botulinum toxin A (BTX) injections has…

Lipedema is a progressive connective tissue disease with enlargement of adipose tissue, fibrosis, fluid collection, and dermal thickening. Herein, we present a case of lipedema associated with skin hypoperfusion and ulceration in which soft…

This study aimed to present a novel markerless augmented reality (AR) system using automatic registration based on machine-learning algorithms that visualize the facial region and provide an intraoperative guide for facial plastic and recon…

[OBJECTIVE] The aim of this study was to investigate the efficacy of intraoperative indocyanine green videoangiography (ICG-VA) and intraoperative neuromonitoring (IONM) to prevent postoperative ischemic complications during microsurgical c…

[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…

[BACKGROUND] Direct-to-implant breast reconstruction is a standard method of implant-based reconstruction; however, the risk of skin necrosis and implant failure exists. During simultaneous contralateral augmentation, an implant larger than…

[BACKGROUND] The mandible is a functional bio-organ that supports facial structures and helps mastication and speaking. Large mandible defects, generally greater than 6-cm segment loss, may require composite tissue reconstruction such as os…

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…

[OBJECTIVE] The purpose of this study was to evaluate the outcomes of long-term botulinum toxin type A (BoNTA) treatment for adductor spasmodic dysphonia (AdSD) and to determine the factors predictive of treatment response by investigating …

[OBJECTIVE] This study aimed to compare the long-term efficacy, durability, and dose and interval stability between alternating unilateral and bilateral injections of botulinum neurotoxin type A for the treatment of adductor spasmodic dysph…

[BACKGROUND] Even though scars are major issues for patients who undergo facial lacerations, programs for their prevention and early management are not well established. The purpose of this study was to evaluate the clinical outcomes of pro…

[BACKGROUD] Outcomes of traditional treatment for osteonecrosis of the femoral head (ONFH) are not always satisfactory. Hence, cell-supplementation therapy has been attempted to facilitate necrotic-tissue regeneration. Adipose-derived mesen…

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…

[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] Polydioxanone (PDO) is absorbable thread which is usually used for wound closure and face lifting. These days, PDO thread is used increasingly for aesthetic purposes such as correction of facial wrinkles, laxity and even rhinop…

[BACKGROUND] Conventional procedures including botulinum toxin and filler injections have their limitations in improving deep wrinkles and decreasing tissue laxity, and possess the propensity for vascular accidents. Absorbable thread is a r…
