Background: Transforaminal percutaneous endoscopic lumbar discectomy (PELD) has become a routine surgical procedure because it is minimally invasive. Perioperative complications such as dural injury, infection, nerve root irritation and recurrence can occur not only with PELD, but also with conventional open microsurgery. In contrast, post-operative dysesthesia (POD) due to existing dorsal root ganglion (DRG) injury is a unique complication of PELD. Read More

Background: Radiosurgical management of large cystic metastatic brain tumors represents a significant challenge. Nevertheless, modified dose planning has shown beneficial results in such cases.

Method And Results: "Donut's shape" radiosurgical treatment planning is based on the chain-like application of multiple, small-sized isocenters for selective coverage of the contrast-enhancing tumor capsule and minimal irradiation of the central cystic area. Read More

Background: After completing a craniotomy, it is important to replace the removed bone flap in its natural position in order to guarantee brain protection as well as improve cosmesis. A skull defect can expose the brain to accidental damage, and in cases of larger defects it may also cause the patients psychosocial problems. The ideal fixation device should provide reliable attachment of the flap to the skull and promote fast bony healing to avoid possible pseudo-arthrosis and/or osteolytic changes. Read More

Background: Parenchymal hemorrhage is one of the most feared risks of stereotactic brain biopsies potentially resulting in neurological deficits or even a fatal outcome. Patients with disorders of the coagulation system are at particular risk, so identifying these is one of the main tasks prior to surgery. Some patients may have a bleeding tendency despite normal laboratory values of the hemostatic system. Read More

Background: Bony defects extending laterally or superiorly within the posterior wall of the frontal sinus are generally deemed too difficult for endoscopic repair in spite of significant progress in surgical endoscopic techniques.

Patients And Methods: We describe a technique of endoscopic repair of posttraumatic cerebrospinal fluid (CSF) leak from the postero-superior aspect of the frontal sinus in a 40- and a 29-year-old male. In both cases after careful assessment of the surgical anatomy the sinus was widely opened transnasally (Draf IIB and Draf III approach, respectively). Read More

Introduction: Arteriovenous fistulas (AVF) are rare vascular lesions of the brain that differ from arteriovenous malformations as they present a direct connection between artery and vein, without interposition of the nidus. They are fed by one or more arterial branches, with a single draining vein. Clinically they can be revealed through cerebral hemorrhage, convulsive crisis, neurological deficit, heart failure in neonates and infants, headache, bruit, or intracranial hypertension symptoms.

Background: In 1908, Anton and von Bramann proposed the Balkenstich method, a corpus callosum puncture which created a communication between the ventricle and subarachnoid space. This method offered the benefit of providing continuous CSF diversion without the implantation of cannula or other shunting devices, yet it received only slight reference in the literature of the time. It remained a novel and perhaps underutilized approach at the time Cushing began expanding his neurosurgical practice at the Johns Hopkins Hospital. Read More

Background: The surgical treatment of lumbar stenosis traditionally includes laminectomy for direct decompression of the spinal canal. Selected patients with spinal stenosis may also require lumbar fusion. Minimally invasive lateral transpsoas interbody fusion has the ability of placing a large interbody cage that can increase disc height and distract the spinal level. Read More

Background: Epistaxis is one of the most common emergencies of ENT surgery and can be managed conservatively in most cases. However, transarterial embolization is an accepted treatment option for intractable epistaxis, if conservative management fails. But often, direct detection of the bleeding point by obvious contrast extravasation is not possible in conventional subtracted angiographic series (DSA). Read More

Background: The expanded endonasal approach of the cranio-cervical junction provides comfortable working space while avoiding some of the disadvantages of the transoral route. We report a purely endonasal endoscopic resection of the odontoid process for basilar invagination in a patient with a Chiari type I malformation, without posterior decompression or fusion.

Department of Neurosurgery, G B Pant Hospital, New Delhi, India.

Background: Anterior cervical discoidectomy with or without fusion is a well established surgical remedy for cervical prolapsed intervertebral disc (PIVD) disease. If fusion is done by an iliac bone graft then internal fixation is commonly used to keep the graft in position. This study was conducted to determine the efficacy and tolerability of shape memory alloys, especially NiTi (nickel titanium) clips in the stabilization of grafts following anterior cervical discoidectomy.

Background: The management of symptomatic thoracic disc herniation (TDH) has evolved tremendously ever since the first laminectomy was performed. The last decade has witnessed the evolution of minimally invasive approaches for TDH most of which have been posterior/posterolateral. Traditional anterior approaches involve a thoracotomy or more recently, thoracoscopic techniques. Read More

Background: The aim of this study was to identify the anatomic landmarks of sella turcica on the surface of the head, and to investigate the feasibility of studying sella turcica anatomy individually by three-dimensional computed tomography (3D-CT) before an endonasal transsphenoidal operation.

Patients And Methods: The three-dimensional anatomic structures of the heads of 49 patients were studied by 3D-CT using image reconstruction with surgical clip image registration. The tip of the nose and the apex of the ear helix were used as surface markers on the head, and the locations of the sphenoid sinus and sellar floor with respect to a line defined by these 2 markers were investigated.

Background: Lumbar foraminal stenosis is a troublesome disease. Decompression of the whole length of the nerve root from the spinal canal to extraforaminal zone is often a surgical requirement due to the difficulty in identifying the nerve compression site before surgery, making preservation of the posterior elements difficult. The authors report a minimally invasive microendoscopic technique for lumbar foraminal stenosis to decompress the entire length of the nerve root from the spinal canal to the extraforaminal zone while preserving the posterior elements.

Background: Over the last decade, neuroendoscopy has re-emerged as an interesting option in the management of intraventricular lesions in both children and adults. Nonetheless, as it has become more difficult to use cadaveric specimens in training, the development of alternative methods was vital. The aim of this study was to analyze the performance of a real simulator, in association with image-guided navigation, as a teaching tool for the training of intraventricular endoscopic procedures.

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. Read More
