1.ENDOSCOPIC FOREHEAD LIFT COMBINED WITH ALLODERM(R) IMPLANTATION TO CORRECT FOREHEAD DEEP WRINKLES.
Journal of the Korean Society of Aesthetic Plastic Surgery 1999;5(2):281-287
Forehead deep wrinkles make man's face ugly. Especially, in case that a young people has short forehead, one or two forehead deep wrinkles is likely go give a aggressive impression to people. Traditional forehead lift basically not only perfrom the selective excision of frontalis muscle which cause forehead wrinkles, but extend the width of forehead by practical lift through scalp excision. Recently, various filling materials such as collagen have been developing, and laser resurfacing and endoscopic plastic surgery has gradually been generalized, so the frequency of the traditional forehead lift which needs the extensive operation through coronal incision is gradually diminished. But collagen injection is repeatedly taken every regular times and it has a weak point that the width of forehead cannot be regulated. Laser resurfacing can't solve the problem of deep wrinkles. The purpose of endoscopic brow lift which has been generalized currently is mainly brow lift, and so this method is not good for deep wrinkles because it can't modualte frontalis muscle which cause forehead transverse wrinkles. Recently it has been reported that Alloderm composed of dermal collagen from cadavar skin is universally used in covering as well as filling up soft tissue defect and its usability is also successful. Authors recently correct three young persons who have forehead deep wrinkles by combination of endoscopic forehead lift and subcutaneous Alloderm implantation under the wrinkles for 2 years. At first, we extended the width of forehead and smoothed the depth of wrinkles by endoscopic brow lift. After having endoscopic operation, we inserted Alloderm in subcutaneous pocket and performed suspension suture outside. The average increase of forehead width is 5 mm and all patients had corrected transverse wrinkles remarkably. During the 9 months, wrinkles didn't recur and implanted Alloderm also didn't absorbed. As a better method, authors reported that combining endoscopic brow lift with Alloderm implantation for the correction of short forehead and deep wrinkles could be used in place of traditional forehead lift.

Flap survival is critical to the success in reconstructive surgery, there have been many investigations to increase the blood supply to the flaps such as surgical delay and pharmacologic delay. Prostaglandin(PG) is released from various tissues including blood vessel in response to physical stimulus. Among the Prostaglandins, PGE1 has been proven to be a vasodilatation property and many authors have demonstrated its effect to increase blood supply after random cutaneous flap surgery. Clinically, however, muscle flap or musculocutaneous flap is more significantly used in reconstructive surgery and hemodynamic effects of PGE1 of this type of flap are still not documented. The authors designed the random muscle flap to study the hemodynamic effects of PGE1 of the muscle flap. Superior based rectus muscle flap was elevated from rats and the superior epigastric artery, its major vascular pedicle, was ligated to create the random-type muscle flap. Twenty two rats were divided into two experimental groups and each group had 11 rats; Group I: No drugs Group II: PGE1 injection group for 7 postoperative days intraperitoneally The average muscle flap survival rate of group I was 46+/-3.0 precent and it had a higher survival rate than the control group(23+/-4.3%). The muscle flap survival rates showed significant differences between the two groups (p< 0.005) This study shows that the administration of the PGE1, in clinical usage of the rare random muscle flap with a pedicle injury or musculocutaneous flap with the risk of distal cutaneous flap necrosis, such as TRAM flap, which might be much safer and popular.

Archives of Aesthetic Plastic Surgery 2020;26(4):132-137
Background:
In Asian women who undergo facelift procedures, satisfying results are achieved for facial rhytides, but sometimes there are postoperative complaints concerning the mandibular angle. Unlike Caucasians, Asians generally have a prominent mandibular angle. Accordingly, bone contouring surgery must be considered, since the bones of the face serve as the frame for facelift surgery. We investigated the effects of simultaneously performing mandibular angle reduction and facelift to achieve an oval facial contour and a youthful face.
Methods:
We evaluated 17 Asian women who simultaneously underwent mandibular angle reduction and facelift between April 2016 and May 2018. The clinical results were assessed based on preoperative and postoperative photographs and the Global Aesthetic Improvement Scale.
Results:
Surgery was successful in all cases. Postoperatively, improvements in facial rhytides and appropriate mandibular contours were achieved. All patients were satisfied with the outcomes. Some patients experienced short-term complications, such as hematoma and numbness of the skin above the incision line; however, these complications improved. Serious long-term complications were not noted.
Conclusions
Highly satisfying outcomes can be achieved with combined mandibular angle reduction and facelift for Asian women with a wide and rectangular face.

Archives of Aesthetic Plastic Surgery 2020;26(4):138-143
Background:
In Asian women who undergo facelift surgery, satisfactory results are typically achieved with regard to facial rhytides, but concerns have been reported regarding the postoperative appearance of the malar prominence region. Anatomically, compared to Caucasians, Asians have thick skin and a wide and short facial geometry. Asians generally exhibit zygomatic protrusion; accordingly, bone contouring surgery, which alters the base frame used in a facelift, should be considered. We aimed to investigate the effects of simultaneous reduction malarplasty and facelift to achieve appropriate malar repositioning and a youthful-looking face.
Methods:
We assessed 16 Asian women who underwent simultaneous reduction malarplasty and facelift between March 2014 and March 2018. The clinical results were assessed based on preoperative and postoperative photographs and Global Aesthetic Improvement Scale scores.
Results:
Surgery was successful in all cases. Postoperative improvement with regard to facial rhytides and appropriate malar repositioning were achieved. All patients were satisfied with the outcomes. Some patients experienced short-term complications, but their conditions improved. Serious long-term complications were not noted.
Conclusions
Highly satisfactory outcomes can be achieved with combined reduction malarplasty and facelift for Asian women with wide faces.
7.Alternative Use of Inferior Blow-out Fracture Reduction with Urinary Balloon Catheter.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2007;34(6):729-734
PURPOSE: The operative treatment for blow-out fracture involves restoration of intra-orbital soft tissue and bony structural integrity. There are several methods for reconstruction of inferior blow out fracture. We report reduction of inferior blow-out fracture with urinary balloon catheter in comparison with Medpor(R) using group to complication rate. METHODS: A retrospective study was performed on 67 patients who underwent inferior orbital blow-out fracture reconstruction with Medpor(R) implant or urinary balloon catheter following between 2003 and 2006. Hospital records were reviewed especially for preoperative and postoperative enophthalmos, diplopia, extraocular muscle movement limitations, and hypoesthesia between Medpor(R) implant group and balloon catheter using group. RESULTS: There was no significant statistical difference between both groups on incidence of postoperative complications of enophthalmos, diplopia, extraocular muscle movement limitations, and hypoesthesia. Postoperative infection, ectropion were absent in both groups. CONCLUSION: The use of urinary balloon catheter is simple, fast and inexpensive. Urinary balloon catheter is an alternative and reliable use for reduction of inferior orbital blow-out fracture.

8.Effectiveness of Nanocrystalline Silver(Acticoat(R) Dressing at Wound Infected by Multidrug Resistant Bacteria.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2007;34(6):691-696
PURPOSE: The emergency of multi-drug resistant stains of bacteria represents a challenge in the field of plastic surgery. Especially, MRSA(methicillin-resistant Staphylococcus aureus) and Pseudomonas aeruginosa have strong pathogenicity as well as multi-drug resistance so that they have become a lot more problematic strains. This study has been planned to reduce the bacterial burden by applying Acticoat(R)(Smith & Nephew Healthcare, Hull, England)?dressing into the chronic wounds infected by multi-drug resistant strains and to facilitate their healing. METHODS: Nanocrystalline silver dressings(Acticoat(R)) were applied to chronic wound infected by MRSA or Pseudomonas aeruginosa. Multi-drug resistant bacteria were smeared over a slide glass using sterilized cotton swabs and gram stains were performed directly before and after applying Acticoat(R) dressings at 1, 24, 48 and 72 hours. The gram-stained slides were observed using an optical microscope magnified 1000 times(x1000). The bacterial counts of the control group(0 hour) were compared to those of the experimental groups(1, 24, 48, and 72 hour). Paired T-test was used to assess a statistical significance. MRSA was cultured in two BAPs(blood agar plate) and two MacConkey plates with streak plate method. None were interventions on one culture plate, while on the other culture plate, Acticoat(R) was placed in a square shape and cultured for 72 hours at 37 degrees C, then plates were examined. Pseudomonas aeruginosa was cultured in the same manner as MRSA. RESULTS: There are the large amount of declination of bacterial counts with statistical significance after Acticoat(R) dressing. The bacteria grew in culture plate without specific intervention, but no bacteria grew in culture plate with applying of Acticoat(R) dressing. CONCLUSION: We believe that Acticoat(R) dressing could be used as an effective method of treating chronic wounds which are infected by multi-drug resistant organisms.

9.Reconstruction of Scalp Defects using Bilobed Flap.
Journal of the Korean Cleft Palate-Craniofacial Association 2003;4(1):53-57
The bilobed flap is often used when the primary closure of a skin defect is difficult. We applied a simple and rational method to design a bilobed flap for closure of scalp defect that reconstruction was comparatively difficult. In our method, two triangle flaps are designed; the angle of the first flap is three-fourths the angle of a rhombus at the defect site, and the angle of the second flap is also three-fourth that of the first flap. We applied it to five patients with scalp defect and obtained favorable result. The location of the defect was the parietal region in two cases. the occipital region in two cases. the frontal region in one case. We found that the alopecia by scar formation could be minimized with the designed bilobed flap. The suture line, being "Z" shape, was unnoticeable due to hair line stream. There are several advantages of this method for use in reconstruction of scalp defect such as, easy design and elevation of the flap and short operation time.

10.Effects of Poly-N-acetyl Glucosamine(pGlcNAc) Patch on Wound Healing in db/db Mouse.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2008;35(2):121-126
PURPOSE: Poly-N-acetyl glucosamine(PGlcNAc) nanofiber-based materials, produced by a marine microalga, have been characterized as effective hemostatic and angiogenic agents. The similarity between PGlcNAc patch and the natural extracellular matrix allows it to support new healthy tissue growth in an injured area and to encourage fluid absorption. In this study, we hypothesized that a poly-N-acetyl glucosamine fiber patch(PGlcNAc patch) may enhance wound healing in the db/db mouse. METHODS: PGlcNAc patches were applied on one square centimeter, full-thickness, skin wounds in the db/db mouse model. Wounds(n=15 per group) were dressed with a PGlcNAc nanofiber patch for 1 hour(1h), 24 hours(24h) or left untreated(NT). After the application time, patches were removed and wounds were allowed to heal spontaneously. The rate of wound closure was evaluated by digital analysis of unclosed wound area in course of time. At day 10, wounds(n=7 per group) were harvested and quantified with immunohistochemical markers of proliferation(Ki-67) and vascularization (platelet endothelial cell adhesion molecule, PECAM-1). RESULTS: Wounds dressed with PGlcNAc patches for 1 hour closed faster than control wounds, reaching 90% closure in 16.6 days, nine days faster than untreated wounds. Granulation tissue showed higher levels of proliferation and vascularization following 1h treatment than the 24h and NT groups. In addition to its hemostatic properties, the PGlcNAc material also appears to accelerate wound closure in healing-impaired genetically diabetic mice. CONCLUSION: This material, with its combination of hemostatic and wound healing properties, has the potential to be effective agent for the treatment of complicated wounds.
