BACKGROUND: Microvascular decompression is an effective method of treatment in trigeminal neuralgia. It may fail if a compressing vessel is overlooked during surgery. The endoscope has an edge over the microscope in visualizing such conflicts. MATERIALS AND METHODS: This is a prospective study of 51 patients. Preoperative computed tomography and magnetic resonance imaging scans were performed in all the cases. A 4 − 5 cm retroauricular skin incision was made and an about 3 cm craniectomy was performed...

BACKGROUND: Surgical treatment of deep-seated tumors such as supratentorial intraventricular and thalamic-pineal-tectal region tumors carries a risk of postoperative deficits due to possible damage to deep cerebral veins including the internal cerebral vein. It is often difficult to identify whether the vessel encountered during surgery needs to be preserved or not through the small operative field. Therefore, preoperative evaluation of deep venous structures is important. We evaluated the usefulness of 3-Tesla magnetic resonance imaging (3 T MRI) for this purpose...

INTRODUCTION: The shunt operation remains the standard procedure for the treatment of hydrocephalus. We describe a simple minilaparotomy method that involves perforation of the peritoneum with the surgeon's little finger. TECHNIQUE: After placing a small paraumbilical incision at the skin and fascia, the little finger is introduced through the incision to perforate the pre-peritoneal fat and peritoneum. The finger should be inserted at a 30-45° angle to the horizontal plane to avoid injuring the underlying viscera and major blood vessels and to put sufficient shear force on the peritoneum...

INTRODUCTION: Since the first reported endoscopic treatment of colloid cysts of the third ventricle by Powel et al. in 1983, several endoscopic techniques have been described. Therefore, the authors describe their technique of neuroendoscopic colloid cyst removal, developed during the last 16 years. TECHNIQUE: With the aid of the specially designed, no-through perforator, the colloid cyst is first partially evacuated to facilitate further dissection and mobilization...

INTRODUCTION: Despite improvements in sanitation, diagnosis and treatment, neurocysticercosis is still a public health problem in many countries. In symptomatic patients, there is a broad spectrum of clinical manifestations. When cysticerci are lodged in the ventricles or the subarachnoid space, the flow of cerebrospinal fluid can be obstructed and lead to hydrocephalus and intracranial hypertension. The endoscopic view may be useful as a diagnostic tool. PATIENTS: This report clearly shows a common endoscopic pattern in 4 selected patients with ventricular cysticercosis (2 third ventricle/2 lateral ventricle)...

JOURNAL ARTICLE
K S Eom, T Y Kim
INTRODUCTION: Intracranial subdural empyema (ISDE) is a life-threatening intracranial infection. Early and precise detection, timely surgery, and appropriate antibiotic therapy are the keys to a more favorable clinical outcome. Treatment is aimed at complete evacuation of the empyema and eradication of the source of infection. However, in the case of elderly patients or patients with poor health, doctors hesitate to perform open cranial surgery under general anesthesia; thus, the choice of appropriate surgical method is fraught with many limitations...

JOURNAL ARTICLE
S Berkmann, V Schreiber, A Khamis
BACKGROUND: Dislocation of ventriculoperitoneal (VP) shunt catheters is a well known complication after treatment of cerebrospinal fluid disorders; however, secondary perforation of the liver capsule by the catheter is exceptional. The literature on VP shunt complications involving the liver, their possible pathomechanisms and minimally invasive recovery strategies in reference to our own experience is reviewed. CASE REPORT: We present a patient who suffered penetration of the liver by the peritoneal catheter of her VP shunt...

JOURNAL ARTICLE
H Yamahata, H Tokimura, R Hanaya, K Tajitsu, M Hirabaru, M Yamagami, K Arita
BACKGROUND: Trigeminal neuralgia elicited by the vertebral artery is unusual. According to a large trigeminal neuralgia series, only 4 of 1,404 (0.3%) consecutive patients with typical trigeminal neuralgia presented with vertebral artery compression. In such cases the vertebrobasilar system tends to be atherosclerotic, ectatic, and tortuous, requiring, in addition to an ordinary microvascular decompression method, technical modifications of this procedure. We report on 3 patients with trigeminal neuralgia due to compression by a tortuous vertebral artery...

C L Liang, K Lu, P C Liliang, M C Chung, S C Chi, H J Chen
BACKGROUND: Patients who undergo stereotactic gamma knife radiosurgery (GKRS) need a rigid frame fixation for the stereotactic procedures. Many patients suffered from postoperative wound pain after frame removal. The present study investigated whether an additional application of a topical anesthetic prior to frame removal could reduce this discomfort. PATIENTS AND METHODS: 60 patients who underwent GKRS were enrolled in this study. Of these 60 patients, 30 were treated with a topical application of EMLA, a eutectic mixture of 2...

D Wachter, T Behm, J M Gilsbach, V Rohde
BACKGROUND: Tumors originating from or involving the petrous apex are considered to be an operative challenge due to their deep location and close relationship to critical neural and vascular structures. Extensive skull base approaches have been developed to deal with these lesions. The purpose of this study is to review an institutional series of 57 petrous apex tumors, to report our operative experiences and to address the usefulness and limits of standard approaches. MATERIAL AND METHODS: 57 patients (22 men, 35 women) with petrous apex tumors were treated microsurgically...

JOURNAL ARTICLE
P G Campbell, S Yadla, M Rosen, J R Bilyk, A P Murchison, J J Evans
The cryoprobe device is commonly used by orbital surgeons for the extraction of intraorbital lesions. Cryoprobes provide a safe mechanism to manipulate fluid-filled tumors. Such lesions can present in locations in which intraoperative neurosurgical assistance is essential. The authors describe a technique whereby removal of an orbital hemangioma was facilitated by the aid of an endoscopic, transnasal cryoprobe while standard microsurgical dissection was performed concurrently via a transconjunctival approach...

BACKGROUND: The surgical management of deep intra-axial lesions still requires microsurgical approaches that utilize retraction of deep white matter to obtain adequate visualization. We report our experience with a new tubular retractor system, designed specifically for intracranial applications, linked with frameless neuronavigation for a cohort of intraventricular and deep intra-axial tumors. METHODS: The ViewSite Brain Access System (Vycor, Inc) was used in a series of 9 adult and pediatric patients with a variety of pathologies...

JOURNAL ARTICLE
D J Englot, E F Chang, P S Larson
In deep brain stimulation (DBS) surgery, after intracranial lead implantation, lead caps are tunneled into the subgaleal space for later connection to internal pulse generator (IPG) extension wires. In the subsequent IPG implantation procedure, the lead cap must be localized by palpation in order to plan an incision in the scalp to complete this connection. However, if the IPG implantation is done the same day as the intracranial lead implantation, palpation of the lead cap may be challenging in a thick or postoperatively edematous scalp...

JOURNAL ARTICLE
Y Shao, M Li, J-L Sun, P Wang, X-k Li, Q-L Zhang, L Zhang
BACKGROUND: The laparoscopically assisted ventriculoperitoneal (VP) shunt has been widely used in the clinical treatment of hydrocephalus for its simplicity and reliability. Despite significant improvements in shunt procedures, shunt complications remain common. Our clinical experiences suggest that the fixation of the distal (peritoneal) shunt catheter using threads and hemoclips may partially contribute to complications of the distal shunt including obstruction of the shunt and infection...

BACKGROUND: Operating on tumors with close margins to the primary motor cortex requires a precise preoperative planning. Transcranial magnetic stimulation (TMS) is the only preoperative technique for detecting eloquent cortical regions that is directly comparable to direct cortical stimulation (DCS). Combining this well established method in neurological diagnostics with a non-invasive navigation system using the patient's preoperative MRI scans in the NEXTSTIM system might be a promising tool in preoperative planning...

INTRODUCTION: Surgical site infection (SSI) in the setting of lumbar fusion is associated with significant morbidity and medical resource utilization. To date, there have been no studies conducted with sufficient power to directly compare the incidence of SSI following minimally invasive (MIS) vs. open TLIF procedures. Furthermore, studies are lacking that quantify the direct medical cost of SSI following fusion procedures. We set out to determine the incidence of SSI in patients undergoing MIS vs...
