Background: Surgical outcomes after orbital wall decompression have focused on the degree of exophthalmos and intraocular pressure. The aim of this research was to evaluate intraorbital volume using computed tomography (CT) images following two-wall decompression using a combined subcilliary and endoscopic approaches. Methods: A retrospective review was performed for all patients who had undergone the two-wall decompression method. The pre/postoperative CT images were used to evaluate changes in intraocular volume. Intraocular pressure was evaluated using applanation tonometry. Surgical details are discussed within the body of text. Results: Two-wall decompression thru the medial wall and floor was associated with an average intraorbital volume change of $7.3cm^3$, with maximal accommodation up to $13cm^3$. Changes in intraocular pressures were not statistically significant. Conclusion: Two-wall decompression was effective in accommodation of up to $13cm^3$ of soft tissue herniation. There was no statistically significant association between changes in volume to pressure.
Various treatments for trigeminal neuralgia (TN) are known to yield initial satisfactory results; however, the surgical treatment has excellent long-term outcomes and a low recurrence rate. Surgical treatment addresses the challenge of vascular compression, which accounts for 85% of the causes of TN. As for surgical treatment for TN, microvascular decompression (MVD) has become the surgical treatment of choice after Peter J. Jannetta reported the results of MVD surgery in 1996. Since then, many studies have reported a success rate of over 90% for the initial surgical treatment. Most MVDs aim to separate (decompress) the culprit vessel from the trigeminal nerve. To increase the success rate of surgery, accurate indications for MVD and management of the offender vessels without complications are critical. In addition, if there is no vascular compression, partial sensory rhizotomy or internal neurolysis can be performed to improve surgical outcomes.

Abdominal compartment syndrome (ACS) is a life-threatening disorder caused by rapidly increasing intra-abdominal pressure. ACS can result in multiorgan failure and carries a mortality of 60~70%. The treatment of choice in ACS is surgical decompression. There are very few reports of ACS and experience in Korea. We report 12-year-old male patient who developed an abdominal compartment syndrome due to traffic-accident-induced retroperitoneal hematomas, Which was successfully treated by performing a bedside emergency surgical decompression with open linea alba fasciotomy with intact peritoneum. When patients do not respond to medical therapy, a decompressive laparotomy is the last surgical resort. In patients with severe abdominal compartment syndrome, the use of a linea alba fasciotomy is an effective intervention to lower intra-abdominal hypertension (IAH) without the morbidity of a laparotomy. Use of a linea alba fasciotomy as a first-line intervention before committing to full abdominal decompression in patients with abdominal compartment syndrome improves physiological variables without mortality. Consideration for a linea alba fasciotomy as a bridge before full abdominal decompression needs further evaluation in patients with polytrauma abdominal compartment syndrome.
Background: Traumatic spinal cord injury (SCI) is a tragic event that has a major impact on individuals and society as well as the healthcare system. The purpose of this study was to investigate the strength of association between surgical treatment timing and neurological improvement. Methods: Fifty-six patients with neurological impairment due to traumatic SCI were included in this study. From January 2013 to June 2017, all their medical records were reviewed. Initially, to identify the factors affecting the recovery of neurological deficit after an acute SCI, we performed univariate logistic regression analyses for various variables. Then, we performed a multivariate logistic regression analysis for variables that showed a p-value of < 0.2 in the univariate analyses. The Hosmer-Lemeshow test was used to determine the goodness of fit for the multivariate logistic regression model. Results: In the univariate analysis on the strength of associations between various factors and neurological improvement, the following factors had a p-value of < 0.2: surgical timing (early, < 8 hours; late, 8-24 hours; p = 0.033), completeness of SCI (complete/incomplete; p = 0.033), and smoking (p = 0.095). In the multivariate analysis, only two variables were significant: surgical timing (odds ratio [OR], 0.128; p = 0.004) and completeness of SCI (OR, 9.611; p = 0.009). Conclusions: Early surgical decompression within 8 hours after traumatic SCI appeared to improve neurological recovery. Furthermore, incomplete SCI was more closely related to favorable neurological improvement than complete SCI. Therefore, we recommend early decompression as an effective treatment for traumatic SCI.

Objective : The aim of this nationwide study was to analyze the current state of patients with newly diagnosed metastatic spine tumors according to surgical methods. Methods : Data was extracted from the Korean Health Insurance Review and Assessment Service database. Surgery was categorized into three methods : fusion, decompression, and vertebroplasty. Data included patient age, sex, health insurance type, and co-morbidities. Survival rates of metastatic spine tumor patients according to each surgical method were evaluated. Results : Among 1677 patients who had an operation, 823 patients were treated by fusion, 141 patients underwent decompression, and 713 patients were treated by vertebroplasty. The three most prevalent primary tumor sites were the lung, breast, and liver & biliary. On the other hand, the three most prevalent primary tumor sites of patients who underwent surgery were the lung, liver & biliary, and the prostate. The median survival periods for each surgical method in the metastatic spine tumor patients were 228 days for those who underwent surgery, 249 days for decompression, and 154 days for vertebroplasty. Age, sex, and comorbidities significantly affected survival rate. Conclusion : For every primary tumor site, decompression was the least common surgical method during the study period. Although the three surgical methods did not significantly affect the survival period, patients with a poor prognosis tended to undergo vertebroplasty.

Objective : Thoracolumbar junction is second most common level of injury next to cervical spine. The object of this study is to study the usefulness of surgical titanium mesh instead of bone graft, as well as to evaluate the correction of spinal deformity and safety of early ambulation in patients with injury at thoracolumbar junction. Patients and Methods : This review included 51 patients who were operated from July 1994 to December 1997. The injured spine is considered to be unstable, if it shows involvement of two or more columns, translatory displacement more than 3.5mm, decrease more than 35% in height of vertebral body and progression of malalignment in serial X-ray. The decision to operate was determined by (1) compression of spinal cord or cauda eguina, (2) unstable fracture, (3) malalignment and (4) fracture dislocation. The procedure consisted of anterior decompression through corpectomy and internal fixation with anterior instrument and surgical titanium mesh which was impacted with gathered bone chip from corpectomy. Results : Fifty-one patients were followed up for at least 12 months. The main causes of injury were fall and vehicle accident. The twelfth thoracic and the first and the second lumbar vertebrae were frequently involved. Complete neural decompression was possible under direct vision in all cases. Kyphotic angulation occurred in a patient. Radiologic evaluation showed correction of deformity and no distortion or loosening of surgical titanium mesh with satisfactory fixation postoperatively. Conclusions : We could obtain neurological improvement, relief of pain, immediate stabilization and early return to normal activities postoperatively. Based on these results, authors recommend anterior decompression and internal fixation with surgical titanium mesh in thoracolumbar unstable spine injuries.

Purpose: Among the various surgical methods used for the effective treatment of cystic lesion in the jaws historically, decompression procedure has some of superior prognosis compare to direct enucleation. In order to propose the efficacy of decompression we performed this retrospective study to compare decompression procedure with one-stage enucleation in clinical results and prognosis. Patients and Methods: We reviewed 175 patients who had been histopathologically diagnosed cystic lesions from 1996 to 2000 in our department. Patients who had been received decompression alone or secondary enucleation after decompression were 31 cases, and enucleation alone were 144 cases. The age and sex of the patients, the area, size, and histological type of the lesions, and detailed operation and complications including recurrence were investigated. The minimal follow-up period was 2 years. Results: In 31cases of decompression, male patients were 22cases(71%) similar to male predilection(62.3%) in total 175 cases. Cystic lesions were developed evenly in all age groups totally. Decompression was mainly performed in teenagers but enucleation was used in elder decades. In decompression cases the lesions were located in mandibular posterior, maxillary posterior, mandibular anterior, and maxillary anterior in order, which had some differences in total and enucleation cases. In enucleation cases, less than 3cm in size was 77.1% but larger than 3cm was 93.5% in decompression cases. Histopathologically, dentigerous cysts(54.8%), unicystic ameloblastomas(16.1%), and odontogenic keratocysts(12.9%) were seen in decompression cases and no recurrence or metaplasia and infection was observed. On the other hand, permanent tooth loss, numbness, recurrence, and so on were accompanied after enucleation. Conclusion: Although decompression procedure has disadvantages such as many of visiting times and slow recovery of the surgical defect, decompression is the best choice of treatment for large cystic lesions of the jaws, because it prevents functional and cosmetic defect, allows bone regeneration, and makes easy secondary enucleation.
Purpose: The purpose of this study is to present our clinical results after surgical treatment in tarsal tunnel syndrome due to space occupying lesions. Material and Methods: We performed surgical decompression for tarsal tunnel syndrome in 20 patients from July 2004 to February 2007. Out of them, thirteen cases were due to space occupying lesions around the tarsal tunnel. The average age at operation was 51.3 years old and the duration from symptom onset to surgery was 16.5 months. The operation included removal of space occupying lesions and tarsal tunnel decompression. The clinical parameters were pain visual analogue scale (VAS), AOFAS scale, and subjective satisfaction. Results: The ganglion cysts were the most frequent causes (ten cases) and synovial chondromatosis in 1 case, neurofibroma in 1 case, talocalcaneal coalition in 1 case. The average follow-up duration was 14.5 months. The AOFAS scale showed significant improvement from 77.8 to 92.7. The average VAS decreased from 6.4 to 2.2. Seven out of thirteen patients were satisfied with the results. The excellent results were shown in six patients, the good results in one patient, the fair result in three patients and the unsatisfactory results in three patients. Conclusion: Favorable results could be obtained in patients with known etiology. But not all cases with surgical decompression of space occupying lesions showed satisfactory results. We assume that the clinical results were related to the multiple factors, not only well performed surgery but also age, size lesions and duration of symptoms, ect.

Objective : At present, gold-standard technique of cervical cord decompression is surgical decompression and fusion. But, many complications related cervical fusion have been reported. We adopted an extended anterior cervical foraminotomy (EACF) technique to decompress the anterolateral portion of cervical cord and report clinical results and effectiveness of this procedure. Methods : Fifty-three patients were operated consecutively using EACF from 2008 to 2013. All of them were operated by a single surgeon via the unilateral approach. Twenty-two patients who exhibited radicular and/or myelopathic symptoms were enrolled in this study. All of them showed cervical cord compression in their preoperative magnetic resonance scan images. Results : In surgical outcomes, 14 patients (64%) were classified as excellent and six (27%), as good. The mean difference of cervical cord anterior-posterior diameter after surgery was 0.92 mm (p<0.01) and transverse area was $9.77mm^2$ (p<0.01). The dynamic radiological study showed that the average post-operative translation (retrolisthesis) was 0.36 mm and the disc height loss at the operated level was 0.81 mm. The change in the Cobb angle decreased to 3.46, and showed slight kyphosis. The average vertebral body resection rate was 11.47%. No procedure-related complications occurred. Only one patient who had two-level decompression needed anterior fusion at one level as a secondary surgery due to postoperative instability. Conclusions : Cervical cord decompression was successfully performed using EACF technique. This procedure will be an alternative surgical option for treating cord compressing lesions. Long-term follow-up and a further study in larger series will be needed.
Purpose: Diplopia and cosmetically unacceptable enophthalmos are the major complications of blow out fracture. Prolapse of orbital tissue into the sinuses, enlarged orbital volume, atrophy of orbital fat and loss of support of orbital walls play a role in the pathogenesis of enophthalmos. To correct post-traumatic enophthalmos, freeing of incarcerated orbital contents combined with reduction of bony orbital volume and reconstruction of suspensory support of globe is necessary. But remained enophthalmos after surgical treatment is difficult to correct completely. In this case, the authors performed implant insertion for affected orbit and endoscopic orbital decompression for unaffected orbit for correction of late enophthalmos. Method: We reviewed a girl patient with right inferomedial orbital wall blow out fracture, right zygoma fracture treated at our hospital for correction of enophthalmos. An 18-year-old female had sustained posttraumatic enopthalmos. Two surgical management was performed for correction blow out fracture at the other hospital. But residual diplopia, enophthalmos, cheek drooping were found. And then she transferred to our hospital. She had severe enophthalmos(5 mm) also had diplopia and extraocular muscle limitation. We performed operation for correction of enophthalmos. After operation, she showed minimal improvement of diplopia and enophthalmos(3 mm). The authors make plan for operation for correction enophthalmos due to cosmetical improvement. Implant insertion was performed for affected orbit. For unaffected orbit, nasoendoscopic medial orbital wall decompression was proceeded. Result: Correction of enophthalmos was found after operation and was maintained for nine years follow-up. Patient expressed satisfaction for the result. Conclusion: To correct persistant enophthalmos, we could have satisfactory result with orbital wall reconstruction on affected eye and decompression on unaffected eye.
