  • The goal of auricular cartilage harvest is to obtain a sufficient amount for reconstruction and to minimize the change in ear shape. The cartilage can be harvested by a posterior or anterior approach, and each method has advantages and disadvantages. The posterior approach presents the advantage of scar concealment, but there are limits to the amount of cymba cartilage that may be harvested. In contrast, the anterior approach may cause a noticeable scar. However, as cartilage is collected, the anterior approach provides a view that facilitates the preservation ear structure. In addition, it is possible to obtain a greater amount of cartilage. From January 2014 to December 2015, we harvested auricular cartilage graft material in 17 patients. To prevent the development of trapdoor scars or linear scar contracture, short incisions were made on the superior border of the cymba and cavum. Two small and narrow incisions were made, resulting in suboptimal exposure of the surgical site, which heightens the potential for damaging the cartilage when using existing tools. To minimize this, the authors used a newly invented ball-type elevator. All patients recovered without complications after surgery and reported satisfaction with the shape of the ear.

  • Patients are increasingly seeking repair of their earlobes following ear gauging. Research has shown that current repair techniques either excessively reduce the lobular volume or leave an obvious scar along the free edge of the earlobe. In our case series, we describe the use of a novel technique for repairing earlobes following ear gauging using a rolling earlobe flap that preserves the lobular volume and avoids leaving a scar on the free edge of the lobule. The procedure was performed on 3 patients (6 earlobes) who had defects from ear gauging that ranged from 3.0 to 6.5 cm. There were no postoperative complications of infection, wound dehiscence, flap necrosis, hypertrophic scars, or keloids, and all patients were highly satisfied with the postoperative results. This versatile technique allows for an aesthetically pleasing reconstruction of the lobule with the advantages of: the absence of a surgical scar on the free edge of the lobule, preserving the lobule volume, and presenting a highly customizable technique that allows lobules to be created with various shapes and volumes.

  • Foreign body (FB) impaction in the maxillofacial area could be caused by knives, glass fragments, and vegetative materials. We present the rare case of a 62-year-old man with a large glass FB in the left cheek retained for over 40 years. He had traffic accident over 40 years ago and glass fragments impacted on his left cheek. Glass fragments were retained around the zygomatic arch with dimpled scar and unclear serous discharge, but other facial motor or sensory dysfunction was not observed. We confirmed three glass fragments with radiologic examination including plain radiograph and computed tomographic image. Under general anesthesia, impacted glass fragments were removed through the direct incision on the dimpled scar and the additional incision on the left lateral canthal area. Remnant FBs were not seen on an intraoperative C-arm radiograph. After 2 days of irrigation for inflammation control, the dimpled wound was sutured. The wound was healed without major complication and the original dimpled scar was much improved.

  • Safflower (Carthamus tinctorius L.) is a herb primarily distributed throughout in the world. We have used the inter-simple sequence repeats (ISSR) technique to investigate the phylogenetic relationships and genetic diversity of C. tinctorius. Of all germplasms, 88.7% were polymorphic among all germplasms. Mean genetic diversity within germplasms was very low (0.048). The Turkey germplasm had the highest expected diversity (0.082) and Australia germplasm was the lowest (0.020). These values indicate that most of the genetic diversity of safflower is found among germplasms and there is a high among-germplasm differentiation. We found eight phenetic bands for determining the specific marker of germplasm with SCAR markers. The regions of the Mediterranean Sea and India may be the most probable candidates for the origin of safflower. The tree showed four major clades: (1) European germplasms, (2) Azerbaijan, Egypt, and Ethiopia, (3) Australia, and (4) America.

  • Purpose: Authors present the case of 2 patients who underwent extended Latissimus dorsi myocutaneous flap to reconstruct postburn breast deformity. Methods: A 39-year-old woman and 18-year-old woman with postburn breast deformity visited for reconstruction. The nipples were preserved but normal breast development did not occur due to scar contracture. Burn scar contracture was released by excision of the restricting burn scar and breast mound was reconstructed with extended Latissimus dorsi myocutaneous flap. Additional contracture release with multiple z-plasty was performed at the axillae and medial portion of breast. Results: Postburn breast reconstruction using Latissimus dorsi myocutaneous flap showed natural shaped breast mound and inframammary fold. There was no significant complication in both cases. Conclusion: Latissimus dorsi myocutaneous flap provide sufficient skin and soft tissue and it could be an effective method for reconstruction of postburn breast deformity.

  • Congenital melanocytic nevus consists of congregations of nevomelanocytes. It is found in approximately 1% of new born infants. Congenital melanocytic nevus needs to be excised before it transforms into a malignant lesion. Many strategies have been attempted for the removal and reconstruction of the nevus. Serial excision enables wound closure to be accomplished with a shorter scar than if the original lesion was elliptically excised in a single stage and reorientation of the scar closer to the relaxed skin lines. The routine utilization of an elliptical serial excision as a standard method of closure often leads to the formation of elongated scars and waste of skin. The "Cogwheel pattern" serial excision is a new technique for reducing the size of the nevus efficiently. Reducing the final scar length, distributing the tension over many directions, and having the chance of decrease in operation numbers are ultimately achieved with the use of the "Cogwheel pattern" serial excision.

  • Objective : The aim of this study is to report the effect of Hani-maehwa laser(fractional mode) treatment on acne scar. Methods : The patient with atrophic facial acne scars was treated with 5 sessions of laser therapy at 4-week intervals. The therapeutic response to treatment was assessed at 3 months after last laser session. The treatment effect was evaluated by standardized photography, anti aging, skin brightness and flatness. That was measured by micro fluorescence measurement camera(ECO SKIN, Cuvitz Inc.) in 16(left zygoma) and 26(right zygoma) spot. And side effects were also checked. Results : Atrophic facial acne scars have improved markedly. Anti aging, skin brightness and flatness were improved. Especially anti aging and flatness were noticeably improved. Adverse effects were not reported.Conclusions : Korean medicine cautery method applies to high level laser(CO2 Hani-maehwa laser). These are different designs but same principle. It can be considered that laser therapy is effective method for treating acne scars.

  • Purpose: Straight closure line of classic Weir excision leaves visible scars and makes it difficult to precisely approximate resection margins. Hence this study introduces Park-Weir excision that effectively reduces alar width with minimal alar rim scar by 3-dimensional zigzag incision and properly controls the approximation of edges. Methods: From 2008 to 2010, 14 patients underwent Park-Weir excision, crossed wedge excision on alar rim not exceeding 5 mm in width. Each patient was photographed in the same position. Alar width and columellar height against intercanthal distance was compared preoperatively and postoperatively, using image analysis software. Results: Five patients were female and nine were male. Average follow up period was 8 month. Alar width was reduced by 50.50% to 45.96%, original alar width reduced by 8.98% without significant changes in columellar height which was reduced by 0.39%. No visible scar was reported during outpatient follow-up. Conclusion: Park-Weir excision effectively reduces alar width and corrects the flaring of alar without affecting the columellar height. Zigzag incision of Park-Weir excision leaves aesthetically more pleasant scar than straight single incision of classical Weir excision.

  • This study is to generate SCARs markers for identification of Perilla species. A SCAR is a genomic DNA fragment at a single genetically defined locus that is identified by PCR amplification using a pair of specific oligonucleotide primers. We derived SCARs by sequencing and cloning the both ends of the amplified products of RAPD markers. Sixteen sequence-specific primers were synthesized from eight RAPD markers, which were completely sequenced. We developed the species-specific SCAR markers which could be used successfully in detecting genetic variation in four Perilla species. These markers could be used to verify species-origins of various forms of Perilla germplasms.
