After cleft lip repair, many patients suffer from nasolabial fistulas, asymmetrical nasal floor, or an indistinct nostril sill, as well as intraoral wound dehiscence and subsequent scar contracture of surgical wounds leading to vestibular stenosis. For successful primary nasolabial repair of complete cleft deformity of the primary palate, cleft surgeons need special care in reconstructing the sound nasal floor. Especially when the cleft gap is wide or when any type of nasoalveolar molding therapy was not performed, three-dimensional reconstruction of the nasal floor is critical for a balanced nasal shape. In this study, the author describes an effective method for reconstructing a double-layered nasal floor using two mucosal flaps from both sides of the fissured upper lip. This is a report of six patients with unilateral or bilateral complete cleft of the primary palate with a detailed description of the surgical technique and a literature review.

Injuries to the major vessels in the thoracic inlet require early recognition and expedient operative approach. Delayed diagnosis difficulties encountered in the operative exposure of the region are the major factors limiting successful management. This report is a review of 13 patients with vascular injuries to the neck base who were managed at Busan National University Hospital from March 1975 to September 1978 about 3 years and 6 months. The important clinical problems are delineated with emphasis on the technical aspects of operative management. 1] Among 13 cases, 8 cases were male 5 cases were female. 2] Of 28 vascular injuries, subclavian axillary vascular injuries were 22 [78%]. Stab wound was the cause in 70% of these patients. 3] Without extension 7 cases[53.8%] were managed successfully with supraclavicular, and axillary incision. Posterolateral thoracotomy one of extending 4 cases, 2 cases were used right musculoskeletal flap for management of proximal part of the subclavian artery and innominate vessel, 2 cases were used left supraclavicular incision with anterolateral thoracotomy for management of left proximal subclavian artery. One Expired. 4] Repair of vascular injury was accomplished by lateral suture of debridement and end-to end anastomosis in 17[74%]. Autogenous vein was used one for interposition graft. Ligation was required 2 arterial, 6 venous injuries. Of 8 cases which were pulseless preoperatively, 5 cases were able to palpable distal pulse. 5] Post operative complications occurred 50%. Complication of vasular repair was rare. The majority was neurologic deficit (33.3%).

Various cutaneous as well as myocutaneous flaps have been designed for the reconstruction of tissue defects caused by the excision of oral cancer. Among these flaps, cervical island skin flap have been introduced by Farr et al and more have developed by Tashiro et al. This flap has many advantages. The flap minimizes donor size by use of cervical operation wound, flap size available is adequate for most oral defects and the procedure is relatively simple and time saving. However, this flap is not applicable in patients where there are large tissue defects and metastasis is suspected. We used this flap for it's rapid, simple, and effective, primary closure of oral defects after cancer ablation and we have found this flap very useful for the reconstruction of relatively small oral defects.

Intraorbital wooden foreign bodies may present difficulties in diagnosis due to their radiolucent nature. Delayed recognition and management can cause significant complications. We present a case report that demonstrates these problems and the sequela that can follow. A 56-year-old man presented with a 3-cm laceration in the right upper eyelid, sustained by a slipping accident. After computed tomography (CT) scanning and ophthalmology consultation, which revealed no fractures and suggested only pneumophthalmos, the wound was repaired by a plastic surgery resident. Ten days later, the patient's eyelid displayed signs of infection including pus discharge. Antibiotics and revisional repair failed to solve the infection. Nearly 2 months after the initial repair, a CT scan revealed a large wooden fragment in the superomedial orbit. Surgical exploration successfully removed the foreign body and inflamed pocket, and the patient healed uneventfully. However, the prolonged intraorbital infection had caused irreversible damage to the superior rectus muscle, with upgaze diplopia persisting 1 year after surgery and only minimal muscle function remaining. We report this case to warn clinicians of the difficulties in early diagnosis of intraorbital wooden foreign bodies and the grave prognosis of delayed management.

Traumatic abdominal wall hernia is a rare presentation, most commonly reported in the context of motor vehicle accidents and associated with blunt abdominal injuries and handlebar injuries in the pediatric population. A 13-year-old boy presented with multiple traumatic injuries and hemodynamic instability after a high-speed motor vehicle accident. His injuries consisted of massive traumatic abdominal wall hernia (grade 4) with bowel injury and perforation, blunt aortic injury, a Chance fracture, hemopneumothorax, and a humeral shaft fracture. Initial surgical management included partial resection of the terminal ileum, sigmoid colon, and descending colon. Laparostomy was managed with negative pressure wound therapy. The patient underwent skin-only primary closure of the abdominal wall and required multiple returns to theatre for debridement, dressing changes, and repair of other injuries. Various surgical management options for abdominal wall closure were considered. In total, he underwent 36 procedures. The multiple injuries had competing management aims, which required close collaboration between specialist clinicians to form an individualized management plan. The severity and complexity of this injury was of a scale not previously experienced by many clinicians and benefited from intrahospital and interhospital specialist collaboration. The ideal aim of primary surgical repair was not possible in this case of a giant abdominal wall defect.

Purpose: Although traditional and current treatment strategies may demonstrate success, persistence or recurrence of difficult-to-heal wounds remain significant problems. A novel product, Hyalomatrix$^{(R)}$ (Fidia Advanced Biopolymer, Abano Terme, Italy) is a bilayer of an benzyl esterified hyaluronan scaffold beneath a silicone membrane. The scaffold delivers hyaluronan to the wound, and the silicone membrane acts as a temporary epidermal barrier. We present the results obtained with Hyalomatrix$^{(R)}$ in the treatment of difficult-to-heal wounds. Methods: From November, 2008 to March, 2010, Hyalomatrix$^{(R)}$ has been used on total 10 patients with wounds that were expected difficult to heal with traditional and other current strategies. After average 37.4 days from development of wounds, Hyalomatrix$^{(R)}$ was applied after wound debridement. On the average, Hyalomatrix$^{(R)}$ application period was 17.6 days. After average 16.5 days from removal of Hyalomatrix$^{(R)}$, skin grafts was performed. Results: In all cases, regeneration of fibrous granulation tissues and edge re-epithelization were present after the application of the Hyalomatrix$^{(R)}$. And all of the previous inflammatory signs were reduced. After skin grafts, no adverse reactions were recorded in 9 cases. But in one case, postoperative wound infection occured due to a lack of efficient fibrous tissues. In this model, the Hyalomatrix$^{(R)}$ acts as a hyaluronan delivery system and a barrier from the external environments. In tissue repair processes, the hyaluronan performs to facilitate the entry of a large number of cells into the wounds, to orientate the deposition of extracellular matrix fibrous components and to change the microenvironment of difficult-to-heal wounds. Conclusion: Our study suggests that Hyalomatrix$^{(R)}$ could be a good and feasible approach for difficult-to-heal wounds. The Hyalomatrix$^{(R)}$ improves microenvironments of difficult-to-heal wounds, reduces infection rates and physical stimulus despite of aggravating factors.

상처치료 과정 중 ginsenoside Rg1(5,000 ppm, 10,000 ppm) 처리에 의한 효력을 평가하기 위해 SD rats의 등쪽 피부에 biopsy punch를 이용한 4개의 창상을 유발 후, 이 과정에서 일어나는 피부조직의 변화를 관찰하였다. 상처에 Rg1의 도포로 인해 창상치료과정이 활발해짐을 관찰할 수 있었다. Rg1을 처리한 군에서 절개된 상처의 표피화와 수축이 더 빨라졌고 창상면적에 있어서도 양성대조군인 시판연고 도포군과 비교하여 유의하게 줄어들었다. 염색한 조직의 현미경 관찰 결과에서는 정상대조군에서 볼 수 있는 완전한 상피층은 찾을 수 없었으나 Rg1 처리군에서 모낭과 신생혈관이 관찰되었고 상피층의 회복조짐도 관찰되었다. 병변의 TGF-$\beta$ 및 VEGF의 발현량을 조사한 결과 Rg1의 도포에 의하여 더 많은 VEGF의 발현을 유도하고 TGF-$\beta$의 활성화를 차단하여 반흔 형성을 감소시켰다. 이러한 결과를 종합하여 Rg1은 흰쥐의 외과적 창상에 치료효과가 있다고 사료된다.

During the period from March, 1963, to November, 1977, forty-eight patients with secundum type atrial septal defects have undergone surgical repair using cardiopulmonary bypass with a pump oxygenator at the Seoul National University Hospital. Twenty-six [55 percent] of the patients were females and Twenty-two [45 percent] were males. The patients varied in age from 3 years to 51 years. We have divided secundum defects into three types. These are: 1] the high defect; 2] Ovale type defect; and 3] low defect including the defect in the area of the coronary sinus. An ovale type defect was present in forty-one cases [85 percent]. Partial anomalous pulmonary venous connections were present in two patients in the high defect group. All of the forty-eight patients had had right heart catheterization before operation. The pulmonary to systemic flow ratio [Qp/Qs] was determined in our 38 patients. The Qp/Qs was less than 1.5/1 in only five of the 38 patients. Among the 33 patients with moderate and severe left-to-right shunts [Qp/Qs 1.6-3.5/1], the systolic pulmonary artery pressures. ranged from 30 to 80 mm Hg. Large left-to-right shunts [Qp/Qs>3.6/1] were present in 13 patients. The postoperative complications occurred in 13 patients [27. 1 percent]. Postoperative wound infections were the most frequent complications being present in 6 patients [12.5%]. Forty-six of the patients with secundum atrial septal defects survived surgical repair of their defects. Thus the hospital mortality of surgery was 4.2 percent. The causes of death in the early postoperative period were: 1] low cardiac output syndrome related to severe pulmonary hypertension in one case; and 2] postoperative several bleeding in one case.

Between January 1986 and August 1993, 11 patients underwent surgical repair of ventricular septal defect [VSD] complicated with myocardial infarction. The ages of patients were ranged from 22 years to 83 years with a mean of 64 years. There were 8 male and 3 female patients. The preoperative cineangiograms of all patients were reviewed to measure both ventricular function and to evaluate coronary artery disease. The mean time interval between occurance of VSD and operation was 13 days. The operations were performed as soon as possible if there were hemodynamic derangement. Postmyocardial infarction VSD were repaired simultaneuously with coronary artery bypass graft in 3 patients, repaired with left ventricular aneurysmectomy in 6 patients, with left ventricular thrombectomy in 1 patient and with mitral valve chordae repair in 1 patient. There was no early death [within 30 days]. There were 6 postoperative complications; one with perioperative myocardial infarction, two with recurred VSD on postoperative 1 and 6 days respectively, two with lower leg embolism associated with intraaortic balloon pump insertion, one with wound infection. Of the complicated patients, 1 patient with lower leg embolism performed left above ankle amputation. Among two patients with recurred ventricular septal defect, one patient is doing well without problem. On follow up echocardiogram, the residual VSD was occluded completely. However another patient was with recurred VSD died 3 months after the operation because of congestive heart failure. Of the long term survivors, all patients are in NEW YORK Heart Association functional Class I or II. Although number of patients were small, our results of surgical closure of postmyocardial infarction VSD were favored to the others. Moreover, seven patients with preoperative cardiogenic shock among 11 were performed early operation after diagnosis of ventricular septal rupture. All of the patients were survived and doing well during the follow up period. Therefore early diagnosis with aggressive preoperative care with intraaortic balloon pumping and early operation seems to be very important for prevention of deterioration of vital organ.

Upper limb nerve damage is a common condition, and evidence suggests that functional recovery may be limited following peripheral nerve repair in cases of delayed reconstruction or reconstruction of long nerve defects. A 26-year-old man presented with traumatic injury from a wide, blunt wound of the right forearm caused by broken glass, with soft tissue loss, complete transection of the radial and ulnar arteries, and a large median nerve gap. The patient underwent debridement and subsequent surgery with a microsurgical free radial fasciocutaneous flap to provide a direct blood supply to the hand; the cephalic vein within the flap was employed as a venous vascularized chamber to wrap the sural nerve graft and to repair the wide gap (14 cm) in the median nerve. During the postoperative period, the patient followed an intensive rehabilitation program and was monitored for functional performance over 5 years of follow-up. Our assessment demonstrated skin tropism and sufficient muscle power to act against strong resistance (M5) in the muscles previously affected by paralysis, as well as a good localization of stimuli in the median nerve region and an imperfect recovery of two-point discrimination (S3+). We propose a novel and efficient procedure to repair >10-cm peripheral nerve gap injuries related to upper limb trauma.
