Purpose: To analyze the postoperative functional and radiographic follow-up results in patients who underwent percutaneous radiofrequency ablation therapy after the diagnosis of osteoid osteoma. Materials and Methods: Seven patients, who were clinically and radiographically diagnosed with osteoid osteoma from July 1999 to January 2001, and received percutaneous radiofrequency ablation therapy. The average follow-up period was 15.5 months(range, 8~25 months). For the diagnosis and accurate localization of the lesion, simple radiography, computed tomography and magnetic resonance imaging(MRI) were performed preoperatively. Simple radiographs and MRI were taken periodically for the follow-up studies. Results: In all 7 patients, symptoms completely disappeared within 3 days after the operation. The average period of hospitalization was 2.4 days, excluding 1 patient who needed an additional burn treatment. The average postoperative night and day pain scores were 1.8 and 1.3, respectively. The average vocational and recreational activity scores were 1 and 0.6, respectively. Conclusions: Satisfactory functional results were obtained with percutaneous radiofrequency ablation therapy for the elimination of osteoid osteoma. Compared to conventional treatment, the advantages of this therapy were short hospitalization period, no internal fixation and bone graft for preventing fracture, and no limitation of joint motion by long fixation period.

Purposes: Wide scars occurring on the lower face and neck are a source of both functional and esthetic problems. Consequently, we can use skin grafts, pedicled flaps, free flaps, and tissue expansion for the reconstruction of this area. Compared with other reconstruction techniques, tissue expansion is advantageous in that it enables the maintenance of a color and texture similar to that of the adjacent tissue. However, the conventional method of tissue expansion has been reported to lead to an unnatural cervicomental angle and to the deformity of adjacent structures. We have therefore made efforts to prevent these problems through the use of several operative procedures. Methods: Forty-one patients with lower facial and cervical scars underwent tissue expansion. The tissue expansion was performed using a rectangular-shaped Nagosil$^{(R)}$ tissue expansion device. On insertion of the tissue expander, the intermediate area of superficial fat layer was dissected and then the tissue expander was inserted to make a flap that was as thin as possible. In advancement of the flap, a capsule-formed by the tissue expander-was used for the interrupted fixed suture of the flap to the fascia of the platysma muscle of the neck. This procedure was performed multiple times and also performed between the flap and the periosteum of the mandible, such that the tension was removed during the suture of the flap margin. Finally, the patients were fitted with a Jobst$^{(R)}$ facial garment in order to stabilize the operation site at least twelve months. Results: The most prevalent location of the scar was the cheek (15 cases), followed by the chin in 14 cases and the neck in 12 cases. The mean size of scar was $55.7{\pm}39.4cm^2$. Conclusions: Using our procedures, we have experienced no significant deformities and have also achieved a more natural cervicomental angle in the patients.

Purpose: Conventional chest X-ray and pulmonary function test cannot sensitively detect inhalation injury. Bronchoscopy is known to be the gold standard but it is invasive method. We evaluated whether lung inhalation/perfusion scans can sensitively detect inhalation injury of fire victims. Materials and Methods: Nineteen patients (male 9, female 10, mean age 31.6 yr) of fire victims were enrolled in this study. Inhalation lung scan was performed 2 days later after inhalation injury with $^{99m}Tc$-technegas. Perfusion lung scan was performed 4 days later with $^{99m}Tc$- MAA (macroaggregated albumin). Follow up lung scans were performed 16 and 18 days later for each. Chest X-ray was performed in all patients and bronchoscopy was performed in 17 of 19 patients at the same period. Pulmonary function test was performed in 9 patients. Results: Four of 19 patients showed inhalation and perfusion defects and one showed inhalation defect but, normal perfusion scan findings. These five patients with abnormal scan findings showed abnormal bronchoscopic findings and severe respiratory symptoms. On chest X-ray, 2 of them had pulmonary tuberculosis and one of them showed pulmonary congestion. FEV1 /FVC was abnormal in 3 patients. On the follow up scan, all patients with abnormal initial scan findings showed improved findings and they had improved clinical state. Conclusion: Inhalation/perfusion lung scans can detect inhalation burn injury noninvasively in early stage and may be useful in therapeutic decision making and follow up of patients.

To make a objective diagnosis of the syndrome of cold-limbs, We investigated the 20 patients with cold limbs and GI trouble and 20 normal people as a control group. And we compared the thermal difference between Chon-jung(CV17) and Chung-wan(CV12 中脘), Chon-jung(CV17) and Ki-hae(氣海 CV6) and we compared the thermal differences of No-gung(PE8 勞宮) and Yong-chon(湧泉 KI1), too. The results were as follows. 1. All 20 patients had GI trouble and cold limbs. They had the symptom-Indigestion(16 cases-80%) with heart burn, tympanites, abdominal distention, hiccup, belching. Beside that symptom they also had constipation(6 cases-30%), diarrhea(3 cases-15%), headache & dizziness(6 cases-30%). And some had the menstrual syndrome, chronic fatigue, palpitation, insomnia, edema, arthralgia. 2. The thermal difference of the palms between the patients group and the control group were $25.70^{\circ}C,\;25.82^{\circ}C$, but they were not significant. 3. The thermal difference of the soles between the patients group and the control group were $23.58^{\circ}C,\;24.42^{\circ}C$ and the significancy was P=0.020 so it was significant(P<0.05). 4. The thermal difference of the palms and Chon-jung(CV17) between the patients group and the control group were $1.08^{\circ}C,\;0.76^{\circ}C$, but they were not significant. 5. The thermal difference of the sales and Chon-jung(CV17) between the patients group and the control group were $3.01^{\circ}C,\;1.90^{\circ}C$ and the significancy was P=0.003 so it was significant(P<0.05). 6. The thermal difference of Chon-jung(CV17) and Chung-wan(CV12 中脘) between the patients group and the control group was $0.30^{\circ}C,\;0.62^{\circ}C$ and the significancy was P=0.793 so it was significant(P<0.05). 7. The thermal difference of Chon-jung(CV17) and Ki-hae(CV6 氣海) between the patients group and the control group was $0.53^{\circ}C,\;0.68^{\circ}C$, but they were not significant. From the above, I could find the significance of D.I.T.I to diagnose the cold-feet not the cold-hands and the thermal difference between the trunk and limbs was more significant on cold-feet than on cold-hand, either.

The defects of the abdominal wall could be brought about either congenitally, for instances in such cases as omphalocele or gastroschisis, or by various acquired causes-trauma, excision of tumors, excision of burn scar, tissue necrosis caused by infection, hematoma after abdominal surgery, tissue necrosis after radiation therapy and so on. As for the techniques of the reconstruction of the abdominal wall defects, many authors have developed and reported diverse methods. To summarize, primary closure, skin graft, local skin flaps, various myocutaneous flaps, free flap, fascia graft, artificial mesh, tissue expansion, etc could be used in the reconstruction of the abdominal wall defects. The periumbilical perforator-based island skin flap has a many advantages such as no significant sacrifice of the rectus abdominis muscle, wide rotation arc, reliable blood flow of the perforator, short elevation time for flap, and for middle-aged, obese patients, the donor site may be the best from the cosmetic point of view. We used perforator-based island skin flap in 5 cases with reasonable result from March 1999 to May 2001. There were no significant complications and donor sites could be repaired primarily.

Five cases of esophageal cancer developed at the site of esophageal lye stricture were reported. Duration of lye stricture was between 13 and 40years, and all 5 cases had taken normal diet without appreciable troubles after recovery from the acute stage of burn till the suspected onset of esophageal malignaney. Outstanding symptoms of this grave condition were rather acute progressive dysphagia and frequent episodes of esophageal foreign bodies, Diagnosis could be confirmed easily by endoscopic biopsy in suspected eases, and all were epidermoid carcinoma histopathologically. Curative resection of this condition was made in neither of the cases, and their prognoses were more grave than other esophageal malignancies in our experience. The development of esophageal carcinoma at the site of corrosive esophagitis with resulting benign stricture has now been suspected as a cause and effect relationship between these two conditions, and Kiviranta: stated that the incidence of esophageal cancer in patients with lye stricture of longer duration is a thousand times higher than normal population. During last one decade the authors experienced 5 cases of esophageal carcinoma developed at the site of lye stricture of the esophagus among about 350 cases of lye burned esophagus at the Department of Thoracic & Cardiovascular Surgery, the National Medical Center in Seoul, Korea. In Korea they still use lye as a detergent in rural area, and there are still many persons ingesting lye for suicidal attempt or on accident. Lye stricture of the esophagus is, therefore, the most common esophageal disease needing surgical procedures, and the authors believe that there will be much more eases of lye stricture complicated by esophageal eareinoma repoted in near future in this Country.

Objectives : The aim is to comprehend the difference of moxibustion used according to applied body parts (knee pain, neck pain, back pain) to oriental doctors running clinic in Seoul. Methods : A sampling of 288 oriental doctors running clinic in Seoul was done and the doctors were asked to fill out 20 questions by interviewing directly from Nov. 23. 2009 to Jan. 9. 2010. Results : The result shows that moxibustion was used for knee pain and back pain more than neck pain. The type of moxibustion mostly used was sticker moxibustion for all three symptoms. Burn marks were left mostly in knee and back pain. Most large volume of moxa was used to back pain. More than half of the oriental doctors used 1-3 acupoints for one procedure and on average 2-3 sessions was done. Patients with knee pain and back pain had more than 4 sessions compared to neck pain. Treatments were mostly done 3 times a week, and as for total treatment period, it took less than 1 week for acute symptom, and it took more than 1 week and less than 5 weeks for chronic symptom. Conclusions : This research shows that the method of moxibustion used differs according to the area of treatment(knee pain, neck pain, back pain) by survey of oriental doctors through direct interviews.

Background : Electrical burns are one of the most devastating types of injuries, and can be characterized by the conduction of electric current through the deeper soft tissue such as vessels, nerves, muscles, and bones. For that reason, the extent of an electric burn is very frequently underestimated on initial impression. Methods : From July 1999 to June 2006, we performed 15 cases of toe tissue transfer for the reconstruction of finger defects caused by electrical burns. We performed preoperative range of motion exercise, early excision, and coverage of the digital defect with toe tissue transfer. Results : We obtained satisfactory results in both functional and aesthetic aspects in all 15 cases without specific complications. Static two-point discrimination results in the transferred toe cases ranged from 8 to 11 mm, with an average of 9.5 mm. The mean range of motion of the transferred toe was $20^{\circ}$ to $36^{\circ}$ in the distal interphalangeal joint, $16^{\circ}$ to $45^{\circ}$ in the proximal interphalangeal joint, and $15^{\circ}$ to $35^{\circ}$ in the metacarpophalangeal joint. All of the patients were relatively satisfied with the function and appearance of their new digits. Conclusions : The strategic management of electrical injury to the hands can be both challenging and complex. Because the optimal surgical method is free tissue transfer, maintenance of vascular integrity among various physiological changes works as a determining factor for the postoperative outcome following the reconstruction.

Purpose: The two major concerns in skin grafting are poor color match in the recipient site and the donor site morbidity. And, glabrous skin on the palmar aspect of the hands and plantar aspect of the feet attributes define the skin on the palm and fingers sole as functionally and aesthetically different from skin on other parts of the body. When there is a glabrous skin defect, it should be replaced with similar skin to restore function and aesthetics. The palmar crease areas were used to minimize these problems. The purpose of this study is to present the precise surgical technique of the full thickness skin graft using distal palmar and midpalmar creases for aesthetic better outcome for hand injuries. Methods: From May 2006 to April 2010, 10 patients with 11 defects underwent glabrous full thickness skin grafting of finger defects. Causes included seven machinery injuries, two secondary burn reconstructions, and one knife injury. Donor sites included ten glabrous full thickness skin graft from the distal palmar crease and one from the midpalmar crease. Results: Follow-up ranged from 3 months to 24 months. All glabrous skin grafts demonstrated complete taking the recipient sites and no incidence of the complete or partial loss. The donor site healed without complications, and there were no incidences of significant hypopigmantation, hyperpigmentation, or hypertrophic scarring. Conclusion: The important aspects of this method involve immediate return of glabrous skin to the defect site and restoration of the recipient site's crease by simple primary closure from adjacent skin. The glabrous skin of the palm provides the best tissue match for the reconstruction of the hands, but only a limited amount of tissue is available for this purpose. Full thickness skin grafting using palmar crease of the defects is the ideal way of reconstructing glabrous skin to restore both function and aesthetics and minimize donor site morbidity.

The authors analyzed the clinical results of the reconstructive surgery for injuried hand with microsurgery in 33 patients, 35 cases at the department of orthopaedic surgery, school of medicine, Kyung Hee university from 1985 to 1992 and the results were as followings. 1. There were 31 men and 4 women who had a mean age of 23 years(range, 3 to 44 years) and the follow up evaluations averaged 19 months. 2. The causes of the injury were machinery injury in 25 cases, traffic accident in 2, frostbite in 4, burn in 3 and fall down in 1. 3. For the reconstructive procedure, scapular free flap was applied in 6 cases, radial forearm flap in 7, dorsalis pedis free flap in 4, neurovascular island flap in 6, gracilis free flap in 1, wrap around flap in 6, toe to thumb in 5. 4. 32 cases(91.4%)were successful in reconstructive surgery with microsurgery exept the failure of scapular free flap in 2 cases and dorsalis pedis free flap in 1. 5. The causes of failure in scapular free flap were infection in 1 case and thrombosis in 1. In dorsalis pedis free flap, the cause of failure was infection. In the analysis of above results, the reconstruction with microsurgery was effective procedure for reconstruction of injuried hand.
