Septorhinoplasty Using Septal L-Strut Extension Graft: A Long-Term Multidimensional Analysis.
[BACKGROUND] Nasal dorsal augmentation using an alloplastic implant and tip projection using a septal cartilage are generally used in Asian rhinoplasty. Excessive submucosal resection weakens septal support, causing problems due to a heavy …

Functional evaluation of Septal L-strut extension graft in East Asians.
[BACKGROUND] The septal L-strut extension graft (SLEG) consists of anterior extended spreader graft and caudal septal extension graft. SLEG is used to increase the anterocaudal projection from a low-profile nose by creating the de-novo sept…

Deep vein thrombosis in donor or recipient veins encountered during lower extremity reconstruction with a free anterolateral thigh perforator flap: How do we deal with it?
[BACKGROUND] The free anterolateral thigh perforator (ALTP) flap has been successfully adopted to reconstruct traumatic soft tissue defects in the lower extremities. However, the occurrence of deep vein thrombosis (DVT) in donor or recipien…

Long-Term Resorption Rate of Autogenous Onlay Graft in East Asian Rhinoplasty: A Retrospective Study.
[BACKGROUND] Autologous material remains the preferred graft material for use in rhinoplasty. However, resorption rates of autografts remain controversial. In addition, long-term follow-up studies on autografts are rare. Thus, the objective…

Late-Onset Inflammation in Asian Rhinoplasty Using Alloplastic Implants.
[BACKGROUND] Late-onset inflammation is a rare complication that may occur several months to years after undergoing an uneventful rhinoplasty using alloplastic implants and an uneventful postoperative course. Studies to determine the pathop…

Folded Cymba Concha: Is It Large and Stable Enough for Caudal Septal Extension Graft in Asian Rhinoplasty?
[BACKGROUND] Septal extension grafting (SEG) is used for nasal tip projection and positioning. Often, insufficient quadrangular cartilage is available for grafting in Asians, and in most secondary cases the septum is already harvested. We u…

Assessment of Long-term Outcomes of Soft-Tissue Augmentation by Injecting Fibroblasts Suspended in Hyaluronic Acid Filler.
[IMPORTANCE] In previous studies, this group has reported that cultured human fibroblasts suspended in hyaluronic acid (HA) filler might have potential use as a long-lasting injectable soft-tissue filler. However, the data were insufficient…

Protective Effect of Botulinum Toxin against Ultraviolet-Induced Skin Pigmentation.
[BACKGROUND] Hyperpigmentation following ultraviolet irradiation has cosmetic concerns. Botulinum toxin type A can favorably affect skin pigmentation. However, the mechanism of skin pigmentation is unclear. [METHODS] In vitro, human epider…

Septorhinoplasty for Destructed Septal L-Strut in Patients with Previously Applied Porous High-Density Polyethylene Implants (Medpor).
[BACKGROUND] Porous high-density polyethylene implants (Medpor) have been extensively used for septal extension grafts in Asian rhinoplasty. However, studies on the long-term complications associated with Medpor have not been reported. Ther…

Paranasal Augmentation Using Multi-Folded Expanded Polytetrafluorethylene (ePTFE) in the East Asian Nose.
[BACKGROUND] Paranasal augmentation has commonly been performed utilizing alloplastic materials such as silicone or porous polyethylene. However, there are problems such as bone absorption, implant migration, and infection risk attributable…

Clinical Analysis of Nasal Bone Fracture in Patients Who Have Previously Undergone Dorsal Augmentation Using Silicone Implants: A Pilot Study.
[BACKGROUND] There are no studies about the treatment of nasal bone fractures in patients with dorsal augmentations using silicone implants. We aimed to describe the characteristics of nasal bone fracture in patients who underwent rhinoplas…

Septal Extension Graft in Asian Rhinoplasty.
A septal extension graft (SEG) can control nasal tip projection, shape, and rotation. SEG and dorsal alloplastic implants have predominated in Asian rhinoplasty, leading to iatrogenic complications such as a foreshortened nose and destructi…

Do IL-3/GM-CSF effect on the myofibroblastic differentiation of human adipose derived stromal cells?
[BACKGROUND] Capsular contracture is an incurable complication after silicone-based implant surgery. Myofibroblast is the predominant cell in the contracted capsule. We hypothesized that human adipose derive stromal cells (hASCs) together w…

Optimal Viscosity and Particle Shape of Hyaluronic Acid Filler as a Scaffold for Human Fibroblasts.
The authors previously reported that cultured human fibroblasts suspended in a hyaluronic acid filler can produce human dermal matrices with extended in vivo stability in animal and clinical studies. The present study was undertaken to dete…

Comparison of the Matrix Synthesizing Abilities of Human Adipose-Derived Stromal Vascular Fraction Cells and Fibroblasts.
For facial soft tissue augmentation or wound coverage using tissue-engineering technology, cultured fibroblasts have been most commonly used as key cells and their properties have been extensively studied. Clinical strategies based on human…

Correction of pectus excavatum with breast hypoplasia using simultaneous pectus bar procedure and augmentation mammoplasty.
Most women with asymmetric pectus excavatum suffer from hypoplastic breasts. Hence, aesthetic correction of pectus excavatum has to address thoracic wall deformity, breast hypoplasia, and asymmetry.In retrospective series, 21 patients with …

Midface augmentation using bony segments obtained from sagittal splitting angle ostectomy in asians.
[BACKGROUND] Asians characteristically have flat or broad and round facial features. These characteristics are primarily attributable to enlarged and widened jawbones, impressive muscles associated with mastication, and a zygomatic arch inv…
