This study was performed to evaluate the effects of the combination of electroacupuncture (EA) and surgical decompression on paraplegia due to spinal compression in dogs. Ten clinically healthy dogs were assigned into two groups (group A and group B). The one is for the combination of EA and surgical decompression, and the other is for surgical decompression alone. After decompression, neurological function was evaluated daily with modified Tarlov grading system. SEPs were measured as objective evaluation of normal spinal cord function before spinal compression and after neurological recovery. The period of rehabilitation in group A was significantly shorter than that in group B (p<0.05). Conduction velocity of SEPs showed a tendency to return to normal when the dogs got full recovery. According to these results, it was considered that the EA with surgical decompression was more effective than surgical decompression alone for paraplegia resulting from spinal cord injury in dog.

Lumbar decompressive surgery is a standard surgery for lumbar spinal stenosis. Many surgical techniques have been introduced, ranging from open surgery to percutaneous procedures. Minimally invasive techniques are preferred because of the less postoperative pain and shorter hospital stay. Uniportal percutaneous endoscopic decompression has technical difficulties due to the narrow field. Biportal percutaneous endoscopic decompression is a satisfactory technique that can compensate for the shortcomings and provide sufficient decompression.

Ameloblastoma is a benign neoplasm originating from odontogenic epithelium. It is the most common neoplasm in the jaws and is characterized by aggressive behavior and local invasion. Unicystic ameloblastoma (UA) has a unilocular feature in radiologic examination and a cystic feature histologically. Decompression and marsupialization are conservative method of treatment of large UA. The purpose of decompression and marsupialization are size reduction of the mass, which makes it easy to handle at total enucleation with protection of nerve damage and facial deformity. Here we report successful conservative treatment of extensive UA using decompression and marsupialization with a review of literatures.

Cyst is a cavity filled with fluids and semi-fluids that is lined with epithelial cells. Odontogenic cysts are those that form within the jaw which origin from dental follicles, enamel epithelium remnants of the crown, Malassez epithelial cell rest and basal cell layer of the oral epithelium. In such cases, treatment methods such as enucleation, marsupialization, decompression, surgical excision etc. can be used according to the lesion's characteristics, size, relationship with the surrounding tissue, patient's age and developmental status. This case was to report an odontogenic cyst caused by an impacted immature permannent tooth and its treatment. The cyst was removed by decompression. Cystic cavity was healed with bone tissue and the impacted permanent tooth erupted without any recurred cystic lesion.

Purpose: To determine if sparing the interspinous and supraspinous ligaments during posterior decompression for lumbar spinal stenosis is significant in preventing postoperative spinal instability. Materials and Methods: A total of 83 patients who underwent posterior decompression for lumbar spinal stenosis between March 2014 and March 2017 with a minimum one-year follow-up period, were studied retrospectively. The subjects were divided into two groups according to the type of surgery. Fifty-six patients who underwent posterior decompression by the port-hole technique were grouped as A, while 27 patients who underwent posterior decompression by a subtotal laminectomy grouped as B. To evaluate the clinical results, the Oswestry disability index (ODI), visual analogue scale (VAS) for both back pain (VAS-B) and radiating pain (VAS-R), and the walking distance of neurogenic intermittent claudication (NIC) were checked pre- and postoperatively, while simple radiographs of the lateral and flexion-extension view in the standing position were taken preoperatively and then every six months after to measure anteroposterior slippage (slip percentage), the difference in anteroposterior slippage between flexion and extension (dynamic slip percentage), angular displacement, and the difference in angular displacement between flexion and extension (dynamic angular displacement) to evaluate the radiological results. Results: The ODI (from 28.1 to 12.8 in group A, from 27.3 to 12.3 in group B), VAS-B (from 7.0 to 2.6 in group A, from 7.7 to 3.2 in group B), VAS-R (from 8.5 to 2.8 in group A, from 8.7 to 2.9 in group B), and walking distance of NIC (from 118.4 m to 1,496.2 m in group A, from 127.6 m to 1,481.6 m in group B) were improved in both groups. On the other hand, while the other radiologic results showed no differences, the dynamic angular displacement between both groups showed a significant difference postoperatively (group A from 6.2° to 6.7°, group B from 6.5° to 8.4°, p-value=0.019). Conclusion: Removal of the posterior ligaments, including the interspinous and supraspinous ligaments, during posterior decompression of lumbar spinal stenosis can cause a postoperative increase in dynamic angular displacement, which can be prevented by the port-hole technique, which spares these posterior ligaments.

Purpose: We describe a all-arthroscopic technique for decompression of spinoglenoid ganglion cyst and present our clinical results for this procedure. Materials and Methods: From March 2006 to June 2009, eight patients (7 males, 1 female; mean age 40.6 years; range: 21~61) were included who underwent arthroscopic decompression of spinoglenoid ganglion cyst. The most common symptoms were vague shoulder pain and external rotation weakness, which lasted 6.4 months (range: 3~8) on average. Five of eight patients were noted abnormalities on electromyographic (EMG) examination to have suprascapular nerve neuropathy and magnetic resonance imaging (MRI) showed spinoglenoid ganglion cysts in all eight patients and the cyst size was 2.6 cm (range: 1.8~3.6). Labral pathology was identified intraoperatively in all patients and the cysts were decompressed by the posterosuperior capsulotomy under arthroscopic control and labral repair with suture anchors was performed in six patients. Results: The average clinical outcome scores including Constant and Murley, Simple shoulder test (SST) all improved significantly at the time of the final follow-up and there were no complications resulting from the procedures. All patients including the patients with abnormal EMG study recovered strength on isokinetic strength testing. Follow-up MRI scans were performed on all patients at a mean of 5.2 months postoperatively (range: 3~12) revealed complete resolution of the cysts and no evidence of recurrences were seen at an average of 18 months (range: 12~26) of follow-up. Conclusion: Arthroscopic decompression of spinoglenoid ganglion cyst effectively restores patient function and all patients in this study showed improvement in their postoperative MRI findings. Arthroscopic decompression is also useful in the appropriate treatment for labral pathology and may contribute to decreased risk of cyst recurrence.

Purpose : Endoscopic carpal tunnel release technique was developed and has being used to decrease postoperative morbidity and complications. The purpose of this study was to evaluate the clinical results and clinical usefulness of endoscopic carpal tunnel release using single portal technique. Methods and Materials : 18 carpal tunnel syndrome patients who were diagnosed by means of clinical symptoms, physical examination, and electrodiagnostic study had endoscopic carpal tunnel release using single portal technique with about 1 cm oblique wrist incision on 30 hands. And then they were followed-up and reviewed in the same way. Late results of operation were analysed by grading system according to patient's own assessments of relief of symptoms at the final fellow-up. The follow-up period ranged 6 to 13 months from surgery. Results : There were postoperative improvements with respect to clinical symptoms, physical examination, and electrodiagnostic study. 23 of 30 hands$(76.7\%)$ had complete resolution of symptoms. 27 hands$(90\%)$ were able to return to normal activities and work within 6 weeks, and 30 hands$(100\%)$ returned within 8 weeks. In grip strength study, 29 hands$(96.6\%)$ regained preoperative strength in 6 months. 12 of 22 hands$(55\%)$ had improvement with respect to thenar atrophy within 6 months. Late results were as follows . 23 hands$(76.7\%)$ was graded as excellent, 6 hands$(20\%)$ graded as good and 1 hand$(3.3\%)$ graded as fair, and there was no poor result. Conclusion : We think that endoscopic carpal tunnel release with single portal technique is technically safe and simple, if the surgeon takes step to stay within the safety zone based on local anatomy and selects an appropriate patient and that endoscopic carpal tunnel release does have advantages over open release. We agree that the surgeon must be prepared to perform an open technique, if technical difficulties arise, difficulty in introducing the device into the carpal tunnel is encountered, or the transverse fibers of the transverse carpal ligaments are not clearly seen.

Purpose: There are many known treatment modalities for spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy. However, to the author's knowledge, there is no report on the follow-up outcomes focused on remnant cysts. Materials and Methods: Six (n=6) patients with spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy, with a mean follow-up of 15 months (12-23months) following arthroscopic cyst decompression and superior labral repair, were enrolled. Residual cyst was investigated by ultrasonography and MRI. Results: Immediate postoperative ultrasonography revealed complete remission of ganglion cyst in one patient and reduced ganglion cyst size in five patients. Three-month follow-up ultrasonography showed spontaneous complete remission of the residual cysts in all patients. No recurrence on MRI was seen at one-year follow-up. Conclusion: Residual spinoglenoid ganglion cyst remaining after arthroscopic decompression and superior labral repair tends to resolve spontaneously within 3 months of surgery.
