[BACKGROUND] Intradermal injection of CPM-HA20G, a low-viscoelasticity hyaluronic acid (HA) dermal filler with glycerol, has been shown to be effective for facial rejuvenation in Caucasians, but research in Asians is limited. [AIMS] This s…

[BACKGROUND] Immunoresistance to botulinum neurotoxin A (BoNT-A) due to neutralizing antibodies (NAbs) can lead to partial or complete secondary nonresponse (SNR), potentially limiting individuals' aesthetic and/or medical therapeutic optio…

[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…

Pedicle ossification is a rare but significant complication following mandibular reconstruction using a fibular free flap (FFF), a technique widely employed in maxillofacial surgery due to its reliable vascularized bone supply and low donor…

[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…

[BACKGROUND] High-flow nasal oxygenation is an oxygen delivery method by which high concentrations of heated humidified oxygen are supplied via the nasal cavity. This study aimed to investigate the effect of high-flow nasal oxygenation on g…

[BACKGROUND] Surgical management for chondrosarcoma of the temporomandibular joint (TMJ) is challenging due to the anatomical location involving the facial nerve and the functional joint. The purpose of this case series was to analyze the l…

[BACKGROUND] The unique anatomy of the Asian face, along with the influence of cultural forces and regional preferences, has led to the development of specialized approaches to rejuvenation and beautification that are applicable to the aest…

[BACKGROUND] In aesthetic clinical practice, botulinum toxin type A (BoNT-A) is best known for its use as a neuromodulator for the treatment of dynamic facial lines; however, when injected intradermally as microdroplets, BoNT-A can improve …

[BACKGROUND] In advanced breast cancer, radiotherapy is recommended as adjuvant therapy following breast reconstructive surgery. This inevitably led to growing concerns over possible complications of radiotherapy on implants. In this experi…

[BACKGROUND] One of the critical factors for free flap survival is to maintain adequate perfusion. The authors evaluated the effect of epidural anesthesia on arterial maximal flow velocity of the free flap in microvascular lower extremity r…

[BACKGROUND] Most botulinum toxin A (BoNT/A) products contain unnecessary bacterial components that increase the risk of developing neutralizing antibodies (nAbs). Reports of secondary nonresponse and treatment failures (STF) due to nAbs ha…

Accessory breast tissue is remnant mammary gland tissue resulting from a failure of regression during the embryonic development and can occur anywhere along the mammary ridge. Patients with accessory breast tissue may also have chest submam…

[BACKGROUND] Intradermal injections of botulinum toxin have been reported to improve sebum secretion, facial skin laxity, and facial pores. However, the effects of Incobotulinumtoxin-A for these indications have not been reported. [OBJECTI…

The nutritional condition of patients is an important prognostic factor in various diseases. Free flap failure is a serious complication in patients undergoing free flap reconstruction, increasing morbidity and hospital costs. We evaluated …

[BACKGROUND] Diabetes mellitus may have a negative effect on free flap perfusion in patients undergoing reconstructive surgery. Little is known of the effects of lipo-prostaglandin E1 (lipo-PGE1) on flap blood flow in diabetes. This study i…

Periorbital aging involves all layers of the skin, fat, and the bony orbit. Therefore, a multimodal approach is necessary. Twenty Korean subjects who required periorbital rejuvenation were enrolled in this study. First, micro-focused ultras…

Recently launched esthetic botulinum toxin serotype A (BoNT/A) products include Nabota/Jeuveau, Meditoxin/Neuronox, and Botulax, which contain nontoxic accessory proteins and excipients. Clinical evidence supporting these formulations, incl…

[BACKGROUND] A multimodal approach is essential for neck rejuvenation because many factors contribute to the aging of the neck. [OBJECTIVES] We evaluated the effect of combined therapy using microfocused ultrasound with visualization (MFU-…

[BACKGROUND] Quantitative measurements are important for objective evaluation of postprocedural outcomes. Three-dimensional (3D) imaging is known as an objective, accurate, and reliable system for quantifying the soft tissue dimensions of t…

[PURPOSE] The aim of this study was to assess the soft tissue/hard tissue ratio after setback genioplasty for a more precise surgical prediction. [PATIENTS AND METHODS] The surgical records of 22 patients with skeletal class III malocclusi…

[OBJECTIVE] This retrospective study compared genioplasty using Medpor with osteotomy by measuring the amount of anteroposterior change in hard and soft tissue. [STUDY DESIGN] Thirty-three patients who underwent mentum augmentation and who…

The use of compressive dressing is usually spread to enhance neovascularization of the dissected facial flap by elimination of dead space between the flap and the dermis in parotid surgery through facelift incision. The author reports a cli…
