Objective: Posterior cervical laminoforaminotomy is used to relieve cervical nerve root compression caused by a laterallyherniated soft cervical disc or spondylotic spur and its several advantages and disadvantages compared with anterior cervical discectomy were reported. We compared surgical results between soft ruptured disc and foraminal stenosis in posteriorcervical laminoforaminotomyMethods: We performed a retrospective review of 47 patients performed single level posterior cervical laminoforaminotomy for cervical radiculopathy between 2004 and 2012. We divided these patients into two groups, Group A: 27 patients forruptured disc and Group B: 20 patients for foraminal stenosis and analyzed the demographic factors, amount of medialfacetectomy, postoperative instability with neck pain and clinical outcomes. Results: According to the modifed Odom’s criteria, laminoforaminotomy for the ruptured disc showed 92.6% excellentresults and 7.4% good results. For the foraminal stenosis, it was 55.0% excellent and 25.0% good results, which was statistically signifcant. However when both groups were included, overall success rate showed 91.5%. The extent of medial facetectomy for ruptured disc (31.2%) was smaller than for stenosis (48.8%) and it was statistically signifcant. Thirteen patientscomplained of postoperative neck pain for 2 months. There was no instability on dynamic X-ray until the last follow up period and we had two cases complications (4.3%). Conclusion: Although the extent of facetectomy for ruptured disc was smaller than it for stenosis, posterior laminoforaminotomy for the ruptured disc showed the better outcomes than foraminal stenosis.

A Case of Intracranial Wooden Foreign Body: Mimicking Pneumocephalus
김동한,박은석,성한유,박준범,권순찬,심홍보,여인욱 대한신경손상학회 2016 Korean Journal of Neurotrauma Vol.12 No.2
Intracranial wooden foreign bodies are rare. In addition, such objects are difficult to identify with conventional radiographic techniques, such as X-ray radiography or brain computed tomography. A 48-year-old man presented to our emergency room with a headache. Even though he had a history of trauma, he had no external wounds and showed no neurological deficits at the initial examination. He was initially diagnosed with trauma-related pneumocephalus. He developed a delayed intracranial infection and underwent surgery to remove the wooden foreign body. The present case illustrates the necessity for special attention to patients suspected of having pneumocephalus with a rare presentation during the initial examination. Early surgical removal of the intracranial foreign body is necessary to prevent complications.

Thoracic Extradural Cavernous Hemangioma Mimicking a Dumbbell-Shaped Tumor
정원주,최일,성한유,노성우 대한신경외과학회 2015 Journal of Korean neurosurgical society Vol.58 No.1
Dumbbell-shaped spinal extradural cavernous hemangioma is rare. The differential diagnosis of dumbbell-shaped spinal tumors based on magnetic resonance imaging includes schwannoma and lymphoma. Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2–3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic deficit. The cavernous hemangioma was resected through combined video-assisted thoracoscopy and laminectomy without a fusion procedure. The patient had tolerable operative wound pain with no neurologic deficit after surgery. Based on magnetic resonance imaging findings and a review of the literature, we discuss cavernous hemangioma among the differential diagnosis of paravertebral dumbbell-shaped spinal tumors and the importance of complete resection.

Extra-intradural Spinal Meningioma: A Case Report
Seong Kyun Jeong,노성우,성한유 대한척추신경외과학회 2014 Neurospine Vol.11 No.3
Extradural spinal meningiomas are uncommon, and their pathophysiology is not entirely understood. Here, we present the case of a 49-year-old woman with low back and left leg pain of 5 years duration. Magnetic resonance imaging revealed a mass, 1.8-cm in size, with rim enhancement in the spinal canal at the T12 level and extending into the left T12-L1 foramen. In the surgical field, the mass presented with the characteristics of an extra-intradural spinal meningioma. The patient underwent a T12 total laminectomy. A linear durotomy was performed at the midline, and the intradural portion was removed. The extradural portion was not separable from the adjacent dura and the left T12 root, and it was removed by dural excision. Pathological examination confirmed the diagnosis of psammomatous meningioma. We also conducted a literature review of similar cases. Based on our experience with this case, we believe that it is important to clearly distinguish extradural meningiomas from other types of tumors as misdiagnosis can change the operative plan. The long term prognosis of extradural meningiomas is not clear but total excision is thought to be essential.
