Background: Recent trends suggest that minimally invasive cardiac surgery reduces postoperative morbidity and offers a cosmetic benefit. This study was performed to evaluate the CPB time, ACC time, OP time, ICU stay and postoperative hospital stay following a lower partial sternotomy and those of the median sternotomy. Material and Method: A group of 26 adult patients who underwent cardiac surgery through lower partial sternotomy from August 1997 to July 1999(A group) were compared to 45 adult patients who underwent cardiac surgery through median sternotomy from January 1996 to July 1997(B group). The mean ages(46.4$\pm$14.6 years, A group and 46.8$\pm$13.2 years, B group) were similar. Operations were performed with central cannula and antegrade/retrograde blood cardioplegia. Result: There was no death in each group. No differences were found in CPB time, ACC time, OP time, ICU stay and postoperative hospital stay. Postoperative complications were sternal splitting in a patient in group A and a patient with bleeding that required reoperation and a patient with delayed wound closure in group B. Conclusion: The lower partial sternotomy offered a cosmetic benefit, but does not significantly reduced the length of operative time and hospital stay. Minimally invasive cardiac surgery will be applied increasing because of the suggested advantage and choosing a proper operative technique will be helpful.

Conjoined twins are rare, and each set of conjoined twins has a unique conjoined anatomy. It is necessary to perform separation to increase the chance of patient survival. Tissue expansion is an advanced technique for providing sufficient soft tissue and skin for wound closure. We report the successful application of rapid tissue expansion in 10-month-old xipho-omphalopagus conjoined twins in Vietnam. A tissue expander was placed on the anterior body between the sternum and umbilicus with a baseline of 70 mL sterile saline (0.9% NaCl). The first injection into the tissue expander began on the 6th day after expander insertion, and injections continued every 2 days with approximately 30-70 mL per injection according to the expansion of the skin. The expander reached 335 mL after six injections and within 10 days. In order to prepare for surgical separation, expansion was completed on the 15th day after insertion. The expanded skin area was estimated to be 180 cm², which was sufficient to cover both patients' skin deficiencies. The twins presented for surgical separation 6 days following the completion of tissue expansion. Both babies were discharged in good health 1 month after separation.

Purpose: Cervical necrotizing fasciitis tends to involve the deep soft tissues and spread caudally to the anterior chest and mediastinum, often resulting in major complications and death. It may rapidly spread into the thorax along fascial planes, and the associated diagnostic delay results in this descending necrotizing mediastinitis. So, aggressive multidisciplinary therapy with surgical drainage is mandatory. We present a very rare case of descending necrotizing mediastinitis with literature review. Methods: A 53 years old male visited our department 7 days after trauma in neck. His premorbid conditions and risk factors of necrotizing fasciitis were concealed hepatoma, trauma history, chronic liver disease, and nutrition deficit. Computed tomographic scans of the head and neck region were performed in this patient : signs of necrotizing fasciitis, were seen in the platysma, sternocleidomastoid, trapezius muscle and strap muscles of the neck. Fluid accumulations involved multiple neck spaces and mediastinum. At the time, he diagnosed as necrotizing fasciitis on his neck and anterior chest. Necrotic wound was excised serially and we treated this with the Vacuum - assisted closure(VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge and achieving additional 3 pieces drainage tubes in the pockets, continuous negative pressure of 125 mmHg was applied. The VAC therapy was utilized for a period of 12 days. Results: We obtained satisfactory results from wide excision, abscess drainage with the VAC system, and then split thickness skin graft. The postoperative course was uneventful. Conclusion: The refined technique using the VAC system can provide a means of simple and effective management for the descending necrotizing mediastinitis, with better cosmetic and functional results. Finally, the VAC system has been adopted as the standard treatment for deep cervical and mediastinal wound infections as a result of the excellent clinical outcome.

Purpose: The liposuction has been generalized & undergone in the field of plastic surgery and it has had a great influence on fat graft. But despite of liposuction and fat injection being performed widely, we did not focus on complication associated with donor site. So we reported satisfactory result with the intraoperative sustained limited expansion & direct closure to donor site tissue necrosis after liposuction and analyzed the cause & measures of donor site necrosis with the literature investigation Methods: From November 2007 to June 2008, we treated four cases of tissue necrosis and infection surrounding the thigh and forearm. Necrosis after liposuction was 1 case, donor site necrosis after fat injection were 3 cases and MRSA was detected in 2 cases. first, we debrided the necrotic tissue and treated with potadine gauze soaking dressing & susceptible antibiotics. After confirmation of healthy granulation tissue, we used intraoperative sustained limited expansion and closed directly of defect & observed the results. Results: The patient was displeased and worried with the unexpected damage concerning the donor site and the procedure concerning time and financial exhaustion, but after confirming no contracture of the scar tissues and only a thin or slightly widened line of scar, showed satisfaction. Conclusion: Because it is fastidious to avoid donor site complication after liposuction & fat injection, enough explanation and understanding on possible complication to donor site are necessary and careful surgery procedure & materials are required. But if donor site necrosis were occurred although close consideration of possible causes of necrosis, we should think about not only wound healing process but also the sequela like scar contracture & cosmetic effect and treat the most adequate method to satisfying both concerns.

Background Scalp defects may be caused by various etiological factors, and they represent a significant surgical and aesthetic concern. Various surgical techniques can be applied for reconstructive work such as primary closure, skin grafting, pedicled or free flaps. In this article, the authors share their clinical experience with scalp operations using the technique of local flaps and discuss the application of this method from the perspective of not only the size of the defect, but also in relation to the anatomical area, quality of surrounding tissue, and patient's condition. Methods During the period from December 2007 to December 2012, 13 patients with various scalp defects, aged 11 to 86 years, underwent reconstruction with local pedicle flaps. The indications were based on the patients' condition (age, sex, quality of surrounding tissue, and comorbidities) and wound parameters. Depending on the size of the defects, they were classified into three groups as follows: large, 20 to 50 $cm^2$; very large, 50 to 100 $cm^2$; extremely large, 100 $cm^2$. The location was defined as peripheral (frontal, temporal, occipital), central, or combined (more than one area). We performed reconstruction with 11 single transposition flaps and 1 bipedicle with a skin graft on the donor area, and 2 advancement flaps in 1 patient. Results In all of the patients, complete tissue coverage was achieved. The recovery was relatively quick, without hematoma, seroma, or infections. The flaps survived entirely. Conclusions Local flaps are widely used in scalp reconstruction since they provide healthy, stable, hair-bearing tissue and require a short healing time for the patients.

Purpose: Reconstruction of scalp and calvarial defects should provide both aesthetic and functional aspects. The inelastic nature of the scalp and previous surgery or radiation preclude the use of primary closure or a local flap. With development of microsurgical technique, a free tissue transfer is a good option. We use the latissimus dorsi myocutaneous free flap for reconstruction. Materials and Methods: A review of all latissimus dorsi free flap reconstructions performed in nine patients from 2009 to 2012 was conducted. There were six males and three females, ranging in age from seven to 69 years, and nine different regions, including five temporal regions, two occipital regions, and two frontoparietal regions. The flaps ranged in size from $9.0{\times}10.0cm$ to $14.0{\times}15.0cm$. Recipient vessels available for microanastomosis were most often the superficial temporal vessels and two patients had anastomoses to the external carotid artery and internal jugular vein. Results: All flaps survived postoperatively. With a median follow-up period of 14 months, no major complications were noted. However, two patients developed minor wound dehiscence, and a hematoma was observed in one patient. Conclusion: We performed the latissimus dorsi myocutaneous free flap reconstruction, which is one of the most popular reconstructive methods. The latissimus dorsi myocutaneous free flap reconstruction has been proven successful in our patients with satisfactory results. During the long term follow-up period, even though depressions were observed on the defect area in some patients, they were treated successfully with cranioplasty. Therefore, we recommend the latissimus dorsi myocutaneous free flap for reconstruction of scalp and calvarial defects.

This is a 20 year analysis of the problems associated with enterostomy formation, and closure. Forty-three stomas were established in 43 patients: 23 for anorectal malformations, 11 for Hirschsprung's diseases, 4 for necrotizing enterocolitis, 3 for multiple ileal atresias, 1 for volvulus neonatorum with perforation, and 1 for diaphragmatic hernia with colon perforation. Thirty boys and 13 girls were included (mean age 4.8 months). Stoma complications were encountered in 13 patients (30.2 %): stomal prolapse, stenosis, obstruction, paracolic hernia, retraction, dysfunction, and skin excoriation, Four patients (9.3 %) required stomal revision. Occurrence of complications was not related to age and primary disease, but sigmoid colostomy showed lower complication rate than transverse colostomy (20.0 % vs 42.9 %, p<0.05). There were five deaths but, only one (2.3 %) was directly related to the enterostomy complication. Twenty-one stomas were closed in our hospital and complications occurred in seven patients (33.3 %). The most common complication was wound sepsis in 5 children. In conclusion, because the significant morbidity of stomal formation still exists, refinements of the surgical technique seem to be required, Sigmoid loop colostomy is preferred whenever possible.

Purpose: In accordance to an increased interest in facial appearance and the popularization of computed tomography scanning, the number of diagnosis and treatment of blowout fractures has been increased. The purpose of this article is to review pure blowout fracture surgery through transconjunctival incision focusing on complications and their management. Methods: In this retrospective study, 583 patients, who had been treated for pure blowout fracture through transconjunctival incision from 2000 to 2009, were evaluated. Their hospital records were reviewed according to their sex, age, fracture site, preoperative presentations, time interval between trauma and surgery, and postoperative complications. Results: According to postoperative follow-up results, there were early complications that included wound dehiscence and infection (0.2%), hematoma (insomuch as extraocular movement is limited) (0.7%), lacriminal duct injury (0.5%), and periorbital nerve injury (0.7%). In addition, there were late complications that lasted more than 6 months, that included persistent diplopia (1.7%), extraocular movement limitation (0.9%), enophthalmos (1.0%), periorbital sensation abnormalities (1.0%), and entropion (0.5%). Conclusion: We propose the following guidelines for prevention of postoperative complications: layer by layer closure; bleeding control with the epinephrine gauzes, Tachocomb, and Tisseel; conjunctival incision 2 to 3 mm away from punctum; avoidance of excessive traction; performing surgical decompression and high dose corticosteroid therapy upon confirmation of nerve injury; atraumatic dissection and insertion of Medpor Barrier implant after securing a clear view of posterior ledge; using Medpor block stacking technique and BioSorb FX screw fixation; performing a complete resection of the anterior ethmoidal nerve during medial wall dissection; and making an incision 2 to 3 mm below the tarsal plate.

경골 과간 융기부의 견열 굴절은 비교적 드물지 않게 관찰되는 손상으로, 전위된 견열 골절편은 해부학적 정복과 견고한 고정을 필요로 한다. 그러나 관절경적 수술 방법을 포함한 대부분의 잘 알려진 수술 방법들은 비교적 복잡한 수술 기법과 정교한 수술 술기를 필요로 하며, 이에 따른 수술 시간의 지연과 수술 합병증으로 창상 감염, 조기 성장판 폐쇄 및 조기 관절 운동을 제한하는 고정력의 소실 등이 발생할 수 있다. 이에 저자들은 전외측 및 중앙부, 내측 mid-patella 입구를 사용한 관절경적 기법을 이용하여, 골편의 정복에 삽관 나사못을 사용함으로써, 비교적 짧은 수술 시간 안에 만족스런 정복과 고정을 얻을 수 있었으며, 술 후 조기에 능동적 관절 운동을 허용할 수 있었다. 또한 분쇄 골절의 경우 와셔를 사용함으로써 만족스런 고정을 얻을 수 있었다. 저자들의 방법은 수술 기법의 용이함과 금속 제거 시의 안전성, IV형 분쇄 골절에도 적용할 수 있는 점, 추가적인 피부 절개가 필요없다는 점, 성장기 소아에서 성장판의 손상 가능성을 줄일 수 있는 등의 장점이 있다고 사료된다.
