The hand is a frequently affected area in high voltage electrical burn injury as an input or output sites. Therefore, early debridement and synchronous flap coverage are generally accepted as a primary treatment of several electrical burns complicated by exposure of tendons, neurovascular structures, and bones. So, in order to establish convenient, promising methods for the reconstruction of hand defects in electrical burn patients, we performed various reverse forearm flaps. From March 1997 to February 2000, we reconstructed 12 cases of hand defects in high voltage electrical burn wounds with reverse forearm flaps. Reverse radial fasciocutaneous flap were 3 cases, reverse ulnar fasciocutaneous flap were 3 cases, reverse ulnar fasciocutaneous flap and STSG were 4 cases, reverse ulnar fascial flap and STSG were 2 cases. We successfully reconstructed hand defects in all 12 cases, and obtained following conclusions. 1 Various reverse forearm flaps provide well vascularized, profitable tissues and they require short operative time with relatively easy procedures. 2. Reverse fascial flap and STSG, reverse fasciocutaneous flap and STSG provide thin flaps with good aesthetics and minor donor site morbidity.

Objective : A superciliary keyhole approach is an attractive, minimally invasive surgical technique, yet the procedure is limited due to a small cranial opening. Nonetheless, an unruptured supraclinoid internal carotid artery (ICA) aneurysm can be an optimal surgical target of a superciliary approach as it is located in the center of the surgical view and field. Therefore, this study evaluated the feasibility and surgical outcomes of a superciliary keyhole approach for unruptured ICA aneurysms. Methods : The authors report on a consecutive series of patients who underwent a superciliary approach for clipping unruptured ICA aneurysms between January 2007 and February 2012. The data were compared with a historical control group who underwent a pterional approach between January 2003 and December 2006. Results : In the superciliary group, a total of 71 aneurysms were successfully clipped without a residual sac in 70 patients with a mean age of 57 years (range, 37-75 years). The maximum diameter of the aneurysms ranged from 4 mm to 14 mm (mean${\pm}$standard deviation, $6.6{\pm}2.3$ mm). No direct mortality or permanent morbidity was related to the surgery. The superciliary approach demonstrated statistically significant advantages over the pterional approach, including a shorter operative duration (mean, 100 min), no intraoperative blood transfusions, and no postoperative epidural hemorrhages. Conclusion : A superciliary keyhole approach provides a sufficient surgical corridor to clip most unruptured supraclinoid ICA aneurysms in a minimally invasive manner.

Purpose: Traumatic airway injuries have high rates of mortality and morbidity. Thus, we evaluated the clinical results of trauma-related airway-injury patients. Methods: A clinical analysis was performed for patients with airway trauma who were admitted and treated at the Department of Thoracic and Cardiovascular Surgery, Konyang University Hospital from Dec. 2002 to Dec. 2009. Results: Sixteen patients were admitted and treated. Fourteen patients were male, and the ages of the patients ranged from 16 to 75 years. Six cases were penetrating injuries, 4 were traffic-accident injuries. 3 were fall injuries, and. 3 were other blunt trauma injuries. Anato- mic injuries included 14 trachea cases (87.5%), 1 Rt. main bronchus (6.25%), and 1 Lt. main bronchus cases (6.25%). Diagnosis was made by using computed tomography and bronchoscopy. Five patients were treated with an explothoracotomy, and 7 underwent neck exploration with primary repair. Three patients simply needed conservative management, and 1 patient was treated with a closed thoracostomy. The post-operative mortality rate was 6.25 % (1 patient). Conclusion: Airway trauma is dangerous and should be treated as an emergency, so a high index of suspicion is essential for rapid diagnosis and successful surgical intervention in patients with airway injuries.

Twenty-three patients underwent operations to repair a congenital heart disease through right anterolateral thoracotomy(RALT) between December 1989 and December 1996. Defects repaired 22 atrial septum(13 ostium secundum;3 lower sepal defect;4 posterior septal defect; 1 sinus venosus;1 ostium primum) and 1 ventricular septal defect. There was no operative mortality or late morbidity directly related to RALT. The RALT incision is a safe and effective me hod to a median sternotomy in selective patients(especicially female). The cosmetic results are very good during the follow up periods.

Reconstruction of soft tissue defects of the knee has always been a challenging task for plastic surgeons. Various reconstructive choices are available depending on the location, size, and depth of the defect relative to the knee joint. Defects on the knee joint have several characteristic features. The use of a free flap is preferred for reconstructions involving obliteration of large-cavity defects, but recipient pedicle isolation can be difficult because of the extent of the injury zone. Furthermore, the true defect during knee joint flexion is larger than during knee joint extension, and a durable flap is necessary for joint movement. We report for the first time on the use of pedicled perforator flaps for reconstruction of bilateral knee defects in a 76-year-old woman. The operative procedure required skeletonizing the perforators of an antero-lateral thigh flap and antero-medial thigh flap and rotating the flap in the defect. The patient returned to normal daily activity and had a full range of motion two months after the accident. The shorter operating time with decreased donor site morbidity and its durability make this flap a valuable alternative for soft tissue reconstruction of the knee.

Treatment of infected mandibular fracture is confronted with various difficult problem, e.g. nosocomial wound infection, non-union of fracture, osteomyelitis. Recently, nosocomial infection has become a major health problem because of excessive morbidity, personal distress, and cost. Frequently, isolated causative microorganisms of nosocomial infection were staphylococcus aureus, pseudomonas aeruginosa, klebsiella species. The various manifestation of the disease related to the pathogenesis and the clinical course tend to give a bad prognosis after operation. This is a report of case that post-operative infected mandibular fracture in 53-year-old man was not healed even through aggressive I & D and antibiotic treatment.

There are many challenges for reconstruction after intraoral tumor resection. Especially, palatomaxillary reconstruction has two primary goals: closure of the oronasal communication and re-creation of proper myomucosal function. Prosthodontic treatment using obturator and several surgical procedures are selected depending on the size and site of the defect, the difficulty of operative procedure, operation time and donor site problem. Above all, it is considered that radial forearm free flap is the first choice for palatal reconstruction. Our department introduces a novel method using tunnelized-facial artery myomucosal island flap for palatomaxillary defect reconstruction, which can successfully reduce donor-site morbidity, and duration of surgery and hospitalization.

Extra-anatomic bypass was proposed by Freeman in 1952 and has been used for patient with lower extremity arterial occlusion who had very high operative risk, especially elderly or severly illed patient.We had performed 14 cases of extra-anatomic bypasses from Jan. 1991 till July 1993 and having been following up them. Their results were summarized as follow. Among total 14 patients, 13 was male. Their mean age was 64.8 years old, ranged from 48 to 80. The most common complaint was pain on lower limb and they visited hospital 6.1 months in average after onset of symptom. Frequently, they were associated with systemic diseases such as generalized atherosclersis, hypertension, diabetes mellius, etc. Axillary artery was used as donor artery in 8 cases and crossover femoro-femoral or femoro-popliteal bypass was performed in 6 cases. Postoperative complications were notedd in 8 cases so their morbidity rate was 42.8%. Except for two contraindicated cases, one or more anticoagulants were used routinely . Among them, combined use of aspirin and persantine was most commonly applied.After bypass graft, nine cases were occluded beteween 10 and 53 months. So their average duration of freedom from reocclusion was 35.7 months and 3-year patency rate was 63%.

Pulp and palm of the hand and heel of the sole are anatomically unique. Satisfactory reconstruction of these areas presents the plastic surgeon with many challenges and requires durable and sensible skin coverage, minimal donor morbidity and reliable operative procedure. We presents 7 clinical cases of sensate instep free flap transfer in this paper during the last 2 years. Three cases were soft tissue defects due to crushing and avulsion injury on the pulp of finger. 1 case was unstable scar and redundant flap after reconstruction of soft tissue dect of palm and 1 case was contracture of first web of hand. One case was a soft tissue defect due to avulsion injury on heel. Lastly, one case was chronic osteomyelitis with open wound on lateral malleolar area. Follow-up period ranged from 3 months to 2 years. Through the whole follow-up period, all flaps were viable and durable to persistant stress or weight bearing and were sensible enough to porotect the recocstructed area from injuries and maintain functions. In conclusions, the instep free flap should be considered as a valuable tool in reconstruction of hand and extremity requiring durability and sensation.

Urethral reconstruction is a problematic issue, thus its management can be challenging. Different methods using various materials were introduced for urethral reconstruction. The authors have made some changes in the groin flap surgery, affording more successful urethral reconstruction for defects of long urethra and penile soft tissue. A 45-year-old male requested both functional and cosmetic reconstruction of his defected penis, caused by an iatrogenic urethral injury and chronic infection following removal of paraffin self-injected on the penile shaft. The defect affected the full length of the penile urethra, corpus spongiosum, and prepuce. A groin flap was designed, measuring $28{\times}10cm$. The most distal flap was utilized for the construction of the luminal surface of the neourethra; relaxed length measuring 8 cm, and the lumen wide enough. Competent external meatus and neourethra was confirmed by retrograde cystogram and the patient voided with sufficient urine caliber up to 2 years follow-up. This operative technique has advantages. Donor sites have non-hair bearing skin for the neourethra and minimal or almost notrecognizable donor site morbidity. After surgery, the patient was relieved from voiding difficulties combined with psychological stress. The author would like to introduce a unique approach for the urethral and ventral phalloplasty using the groin flap.
