Wound caused by high-tension electrical burns is difficult to manage because the wound is deep and complex. The wound is progressively necrotic due to microvascular injury resulting in deep tissue exposure. So, coverage of the wound at the entry point and the exit point is cumbersome, often requiring flap coverage. We experienced a case of one patient for peroneal artery perforator free flap coverage on the palm of the right hand of the entry point of electrical burn. The left foot wound of electrical exit point was covered by full thickness skin graft. Also a small wound was on the left side of the lower back was the exit point of electrical burn. The lower back wound was healed and recurred repeatedly after burn. On postburn day 6 month, through the radiologic exam, metal shadow was identified in the left gluteus muscle forming chronic sinus. We explored the wound of sinus and a foreign body was identified in the sac as multi braid wires thin as hair. According to the patient's past history, we suspected that the back wound was caused by electrical burn injury through the wires.

Purpose: The purpose of our study was to evaluate the volume of pre- and post operative masseter muscle and bite force in mandibular prognathic patients treated with SSRO with the use of the 3D CT imaging technique and occlusal force meter. Materials and methods: The study group consisted of 12 patients with mandibular prognathism (5 males and 7 females) who underwent mandibular setback surgery (BSSRO) in the Department of Oral and Maxillofacial Surgery, Samsung medical center. Bite force was measured at pre op, post op 3, 6 and 12 months by occlusal force meter(GM10, Nagano Keiki, Japan) The preoperative CT examination of subjects was performed between one month prior to operation and one year after to operation. And muscle volume was measured. Result: As compared to preoperative measurements at 1 year postoperatively the masseter & internal pterygoid muscle volume were diminished (p<0.05) The bite force steadily recovered, so at postoperatively 6 months reached the preoperative level. And at 1 year after operation, the maximum bite force was significantly greater than preoperative levels. No significant correlation was presented between masseter muscle and bite force (p>0.05), internal pterygoid muscle and bite force (p>0.05). Conclusion: In this study, the results showed that volume and bite force of the masticatory muscles decreased significantly immediate after orthognathic surgery for mandibular set-back. However, reduction of maximum bite force disappears within 6 months after surgery.

Tremor is a rhythmic, involuntary and oscillatory movement of body parts, and it is the most common movement disorder. Spasticity is also one of the movement disorders that is commonly accompanied with Complex Regional Pain Syndrome; however, the basic nature of spasticity has not yet been proved. A 25-year-old male patient had two operations and he was being treated because of a back injury that occurred 4 years ago. He suffered from pain, tremor and spasticity on both his lower legs, and his symptoms were diagnosed as failed back surgery syndrome. The tremor and spasticity were aggravated despite of continuous treatments. We then treated him with spinal cord stimulation. His pain, tremor and spasticity disappeared after spinal cord stimulation.

Background: The purpose of this study was to investigate the clinical efficacy of Korean medicine combination treatments for recurring back pain after medical procedures. Methods: This was a retrospective study performed on 311 patients admitted to Daejoen Jaseng hospital who were diagnosed with lumbar spine herniated intervertebral discs. The patients were divided into 2 groups according to whether or not they had undergone at least one medical procedure on the lumbar spine. They were assessed with Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) and EuroQol-5 Dimensions Index (EQ-5D) before and after treatment. Results: Patients who experienced a medical procedure on the lumbar spine in the prehospital phase (Group A), statistically significantly improved EQ-5D and ODI scores. The NRS scores also decreased however it was not statistically significant. Patients who had not undergone a medical procedure on the lumbar spine in the prehospital phase (Group B) had statistically significantly improved ODI and NRS scores. The average EQ-5D score decreased however, there was no statistically significant difference before and after scores in Group B. There was no statistically significant difference in variation in EQ-5D, ODI, and NRS scores before and after treatment between the groups. Conclusion: The results of this study indicated that even after a bilateral procedure and surgery, when pain in patients with lumbar spine herniated intervertebral disc did not decrease, (as in failed back surgery syndrome), Korean medicine combination treatment of postoperative pain was helpful and there was improvement in daily life.

Objective : To determine whether the outcomes of percutaneous epidural neuroplasty (PEN) are influenced by the type of lumbar disc herniation (LDH) and evaluate the effectiveness of PEN in patients with single-level LDH. Methods : This study included 430 consecutive patients with single-level LDH who underwent PEN. Before treatment, the LDH type was categorized as bulging, protrusion, extrusion, and sequestration, while Pfirrmann grades were assigned according to imaging findings. Visual analog scale (VAS) scores for back and leg pain and success rates (Odom's criteria) were assessed at 1, 3, 6, and 12 months after treatment. Results : The mean preoperative VAS scores for back and leg pain were 6.90 and 4.23, respectively; these decreased after PEN as follows : 2.25 and 1.45, respectively, at 1 month; 2.61 and 1.68, respectively, at 3 months; 2.28 and 1.48, respectively, at 6 months; and 2.88 and 1.48, respectively, at 12 months (p<0.001). The decrease in VAS scores for leg pain was significantly greater in the extrusion and sequestration groups than in the other two groups (p<0.05); there were no other significant differences among groups. More than 70% patients exhibited good or excellent 12-month outcomes according to Odom's criteria. Subsequent surgery was required for 59 patients (13.7%), with a significantly higher rate in the extrusion (25.0%) and sequestration (30.0%) groups than in the bulging (7.3%) and protrusion (13.8%) groups (p<0.05). Nevertheless, subsequent surgery was not required for >70% patients with extrusion or sequestration. Patients with Pfirrmann grades 1-3 (14.0-21.5%) showed a significantly higher rate of subsequent surgery than those with Pfirrmann grade 0 (4.9%; p<0.05). Conclusion : Our findings suggest that PEN is an effective treatment for back and leg pain caused by single-level LDH, with the outcomes remaining unaffected by the LDH type.

Background: Failed back surgery syndrome (FBSS) is a chronic condition that is characterized by persistent back pain following one or more spinal surgeries. Pharmacological interventions, such as the use of opioids and gabapentinoids, are frequently used in the treatment of FBSS. However, prolonged and excessive use of these medications can lead to dependence and adverse effects. This study investigates trends in opioid and gabapentinoid prescriptions among patients with FBSS in Korea from 2016 to 2020. Methods: Data from the Health Insurance and Review Agency were analyzed, and claims listing FBSS were selected for the study. Prescription patterns of opioids and gabapentinoids were classified based on the number of days prescribed per year. Results: Of the 390,095 patients diagnosed with FBSS, 41.6% of the patients were prescribed gabapentinoids, and 42.0% of them were prescribed opioids, while 10.6% of the patients were classified as long-term gabapentinoid users, 11.4% as long-term opioid users, and 7.4% of the patients were found to have long-term prescriptions for both drugs. The proportion of patients who received both gabapentinoid and opioid prescriptions increased annually. The doses of opioids prescribed have also increased along with the increase in the number of patients receiving opioid prescriptions. Conclusions: The prescription rates of opioids and gabapentinoids among patients with FBSS in Korea continue to increase steadily, posing potential risks of addiction and adverse effects. Further research is needed to better understand the actual status of addiction in patients with FBSS.

Orthognathic surgery for Class III malocclusion requires an elaborate preoperative planning using cephalometries or Mock surgery models which enable the surgeon to anticipate postoperative skeletal changes of maxilla and mandible as well as dentition. After surgery, patient's satisfaction is greatly influenced by appearance of soft tissue change. Therefore, it is imperative to predict a relatively accurate soft tissue change prior to surgery. A 5 year retrospective study was designed to evaluate the soft tissue change after sagittal split osteotomy of ramus(SSRO) for class III malocclusion. Analyses of preoperative and postoperative anthropometric measurements were performed. Patients who were treated only by SSRO for class III malocclusion and could follow up for 6 months were studied. Among them, the patients who had history of cleft palate and lip or hemifacial microsomia were excluded. Soft tissue changes were estimated by using the frontal and lateral photographs. Skeletal changes were observed by measuring amount of set back and angular changes of mandible to the reference line by using cephalometries. Relapses were also measured 6 months after the operation. We could observe skeletal changes were more profound than soft tissue changes concerning amount of set back, but soft tissue changes were also profound in angle. Relapse was more profound in skeleton than soft tissue but the amount was not significant. In spite of the variables which may affect proper assessment of the soft tissue change after skeletal relocation, this study can serve as a guide for exact prediction of the postoperative change of soft tissue and skeleton.

Objective : There is a lack of knowledge regarding whether decompression is necessary in treating patients with epidural spinal cord compression (ESCC) grade 2. The purpose of this study was to compare the outcomes of minimally invasive surgery (MIS) without decompression and conventional open surgery (palliative laminectomy) for patients with hepatocellular carcinoma (HCC) spinal metastasis of ESCC grade 2. Methods : Patients with HCC spinal metastasis requiring surgery were retrospectively reviewed. Patients with ESCC grade 2, medically intractable mechanical back pain, a Nurick grade better than 3, 3-6 months of life expectancy, Tomita score ${\geq}5$, and Spinal Instability Neoplastic Score ${\geq}7$ were included. Patients with neurological deficits, other systemic illnesses and less than 1 month of life expectancy were excluded. Thirty patients were included in the study, including 17 in the open surgery group (until 2008) and 13 in the MIS group (since 2009). Results : The MIS group had a significantly shorter operative time ($94.2{\pm}48.2minutes$ vs. $162.9{\pm}52.3minutes$, p=0.001), less blood loss ($140.0{\pm}182.9mL$ vs. $1534.4{\pm}1484.2mL$, p=0.002), and less post-operative intensive care unit transfer (one patient vs. eight patients, p=0.042) than the open surgery group. The visual analogue scale for back pain at 3 months post-operation was significantly improved in the MIS group than in the open surgery group ($3.0{\pm}1.2$ vs. $4.3{\pm}1.2$, p=0.042). The MIS group had longer ambulation time ($183{\pm}33days$ vs. $166{\pm}36days$) and survival time ($216{\pm}38days$ vs. $204{\pm}43days$) than the open surgery group without significant difference (p=0.814 and 0.959, respectively). Conclusion : MIS without decompression would be a good choice for patients with HCC spinal metastasis of ESCC grade 2, especially those with limited prognosis, mechanical instability and no neurologic deficit.
