COMPARATIVE STUDY
J Fraser, H Gebhard, D Irie, K Parikh, R Härtl
BACKGROUND: Minimally invasive spinal surgery (MISS) has evolved over the past years due to the combination of microsurgery, minimal access strategies and neuronavigation. Percutaneous or mini-open pedicle screw placement is a challenge, especially for surgeons not experienced in the use of biplanar fluoroscopy or stereotactic imaging techniques. The aim of the study was to compare the precision of pedicle screw fixation for lumbar fusion procedures using Iso-C/stereotactic 3D neuronavigation (3D NAV) vs...

JOURNAL ARTICLE
Y Sanada, H Kamiyama, K Iwaisako, T Yoshimine, A Kato
BACKGROUND: Anastomosis of the superficial temporal artery (STA) to the middle cerebral artery (MCA) is useful for treating certain patients with internal carotid artery occlusion or MCA occlusion. However, in the case of common carotid artery (CCA) occlusion, since the blood flow in the STA is insufficient, another artery should be used as the donor artery. The cortical branches of the MCA are usually selected as recipients in the STA-MCA bypass. However, the intracranial vascular filling gradually increases over a few months after conventional cortical MCA bypass grafting, while early or even immediate vascular filling is observed after proximal MCA bypass grafting...

H Arishima, M Sindou
Case 1, a 61-year-old female presented with paresthesia of her right upper lip. Computed tomography (CT) and magnetic resonance (MR) imaging with contrast material revealed an enhanced mass in the right Meckel's cave, which included the lateral and posterior parts of the cavernous sinus and surrounded the right internal carotid artery. To establish the best surgical strategy, a percutaneous biopsy through the foramen ovale was performed, and the histological examination indicated that the tumor was a transitional meningioma...

JOURNAL ARTICLE
M K Kasliwal, V K Anand, E Lavi, T H Schwartz
BACKGROUND: Nasal glioma or glial heterotopia is a rare embryologic anomaly that heralds its presence shortly after birth or in childhood. Nasal glioma in an adult is very rare, often asymptomatic and the occurrence of nasal glioma in Meckel's cave in an adult has not been previously reported. CASE REPORT: The authors encountered a case of an incidentally diagnosed Meckel's cave nasal glioma in a 40-year-old male which was successfully excised by an endonasal endoscopic transmaxillary transpterygoid approach...

BACKGROUND: Interspinous stand-alone implants are inserted without open decompression to treat symptomatic lumbar spinal stenosis (LSS). The insertion procedure is technically simple, low-risk, and quick. However, the question remains whether the resulting clinical outcomes compare with those of microsurgical decompression, the gold standard. MATERIAL AND METHODS: This prospective, comparative study included all patients (n=36) with neurogenic intermittent claudication (NIC) secondary to LSS with symptoms improving in forward flexion treated operatively with either interspinous stand-alone spacer insertion (Aperius (®); Medtronic, Tolochenaz, Switzerland) (group 1) or microsurgical bilateral operative decompression (group 2) between February 2007 and November 2008...

BACKGROUND: Endoscopic lumbar decompression is useful for the treatment of various spinal conditions and is being performed in an increasing number of patients worldwide. We reviewed the surgery-related complications in patients who underwent endoscopic surgery and discuss the learning curve for this procedure. METHODS: Since the first case in August 2000, a total of 138 patients have undergone endoscopic posterior decompression surgery. Of these, there were 74 patients with Herniated Nucleus Pulposus (HNP), 57 with Lumbar Canal Stenosis (LCS), and 7 with other conditions...

BACKGROUND: Endoscopic third ventriculostomy (ETV) is a procedure of choice in the treatment of obstructive hydrocephalus. Neurovascular injury while perforating the ventricular floor can occur when using a conventional probe, especially in patients with a thick and opaque third ventricle floor. The water jet dissection technique can be useful in such cases to perform an initial perforation. PATIENTS/MATERIAL AND METHODS: The water jet dissection technique was used to perform ETV in 36 patients with obstructive hydrocephalus with a thick and opaque third ventricle floor over a 3-year period...

#94
JOURNAL ARTICLE
G Choi, N Prada, H N Modi, N B Vasavada, J-S Kim, S-H Lee
BACKGROUND: L4-L5 disc herniations can be treated with percutaneous endoscopic lumbar discectomy (PELD) using a transforaminal posterolateral approach. Although PELD has some distinct advantages over conventional open discectomy, inadequate decompression is a major cause of failure of the procedure, especially with high-grade migrations. The objective of this technical note is to present a new surgical approach for treating high-grade, down-migrated, L4-L5 disc herniations through an L5-S1 interlaminar endoscopic approach...

JOURNAL ARTICLE
M Philipps, J Oertel
BACKGROUND: Spinal endoscopy is still under controversial discussion. An often acclaimed critic is the poor endoscopic image quality in comparison with the microscope. Since high-definition digital cameras have recently been introduced into spinal neuroendoscopy, the aim of the current study is to examine whether superior image quality has a relevant impact on intraoperativen orientation. MATERIAL AND METHODS: A lumbar endoscopic discectomy was recorded simultaneously in High-Definition resolution (HD) and Standard-Definition resolution (SD)...

BACKGROUND: When the transthoracic approach is used for the treatment of a thoracic ossified posterior longitudinal ligament (OPLL), there could be a lot of operative risks, morbidity, and mortality for the patient. CASE REPORT: A 65-year-old female manifested back pain and tingling sensations in both legs due to OPLL at the T6-7 level. A thoracoscopic procedure was performed to remove the OPLL, achieving complete decompression of thoracic cord. The symptoms were relieved and the patient was discharged on the sixth day after the operation...

BACKGROUND: Arachnoid cysts are often associated with subdural hematoma following head trauma. The incidental finding of an aneurysma and a cyst is rare. We describe for the first time the treatment of such a case using endoscopic techniques. CASE REPORT: A 44-year-old man was admitted to our hospital with a mild headache and a hemifacial spasm attack at the right side of his face. The radiological examinations demonstrated bilateral slyvian fissure arachnoid cysts and an aneurysm with the dome projecting superolaterally, at the bifurcation of the right middle cerebral artery in the arachnoid cyst...

JOURNAL ARTICLE
G Choi, N J Arbatti, H N Modi, N Prada, J S Kim, H J Kim, S H Myung, S H Lee
BACKGROUND: The long-term complications of traditional discectomy and fusion surgery have led to the need for minimally invasive procedures that do not require a complete discectomy and fusion. Jho developed an anterior unco-foraminotomy that we have modified, with the approach being more medial than that of Jho, into an anterior transcorporeal tunnel approach which we use for cervical spondylotic unilateral radiculopathy. METHODS: A retrospective analysis was carried out in 30 patients who underwent a transcorporeal "tunnel" anterior micro-foraminotomy for unilateral radicular symptoms with a follow-up more than 2 years...

JOURNAL ARTICLE
J-M Voyadzis, V C Gala, F A Sandhu, R G Fessler
BACKGROUND: Far lateral lumbar disc herniations, while infrequent, are a substantial cause of morbidity causing painful radicular syndromes often accompanied by a motor or sensory deficit. Surgical treatment can be challenging technically because of unfamiliar lateral anatomy and the importance of adjacent osseous structures, notably the pars interarticularis and facet joint. METHOD: The traditional approach for a far lateral lumbar disc herniation involves a midline incision, wide lateral subperiosteal exposure and partial removal of these structures with the potential for iatrogenic instability...
