OBJECTIVE The comparative efficacy of microscopic and fully endoscopic transsphenoidal surgery for pituitary adenomas has not been well studied despite the adoption of fully endoscopic surgery by many pituitary centers. The influence of surgeon experience has also not been examined in this setting. The authors therefore compared the extent of tumor(More)
OBJECT The optimal management of pineocytomas remains controversial. Although the value of complete microsurgical removal is well accepted, gross-total resection is not always feasible. Data regarding the role of postoperative adjuvant stereotactic radiosurgery (SRS) for residual disease is limited and conflicting. Here, the authors review the largest(More)
Hemifacial spasm (HFS) due to direct compression of the facial nerve by a dolichoectatic vertebrobasilar artery is rare. Vessels are often non-compliant and tethered by critical brainstem perforators. We set out to determine surgical strategies and outcomes for this challenging disease. All patients undergoing surgery for HFS secondary to vertebrobasilar(More)
BACKGROUND Pediatric cerebral venous thrombosis (CVT) is a common sequelae of infection, coagulopathies, and dehydration in the pediatric population. Acute posttraumatic CVT is an uncommon etiology of pediatric CVT that presents a unique management challenge. There are no established guidelines outlining the treatment of this small subset of patients. (More)
OBJECTIVE Treatment advances have resulted in improved survival for many cancer types, and this, in turn, has led to an increased incidence of metastatic disease, specifically to the vertebral column. Surgical decompression and stabilization prior to radiation therapy have been shown to improve functional outcomes, but anterior access to the thoracolumbar(More)
OBJECTIVE Seizures are the most common presenting symptom of newly diagnosed WHO Grade II gliomas (low-grade glioma [LGG]) and significantly impair quality of life. Although gross-total resection of LGG is associated with better seizure control, it remains unclear whether an extent of resection (EOR) "threshold" exists for long-term seizure control.(More)
OBJECTIVE Biomechanical studies demonstrate that cortical bone trajectory pedicle screws (CBTPS) have greater pullout strength than traditional pedicle screws with a lateral-medial trajectory. CBTPS start on the pars and angulate in a mediolateral-caudocranial direction. To our knowledge, no large series exists evaluating the perioperative outcomes and(More)
We report the first case of a neonate with concurrent Chiari II malformation and achondroplasia. Although rare, both these conditions contribute to several deleterious anatomical changes at the cervicomedullary junction and thus predispose to acute hydrocephalus. Although our patient was initially asymptomatic, hydrocephalus ensued several weeks after birth(More)
STUDY DESIGN Retrospective chart review. OBJECTIVE To determine the long-term efficacy of 2-stage total en bloc spondylectomy (TES). SUMMARY OF BACKGROUND DATA TES is a well-described technique to achieve tumor-free margins, but it is a highly destabilizing procedure that necessitates spinal reconstruction. A 2-stage anterior/posterior approach for(More)
Glioblastoma is an aggressive primary brain tumor with devastatingly poor prognosis. Multiple studies have shown the benefit of wider extent of resection (EOR) on patient overall survival (OS) and worsened survival with larger preoperative tumor volumes. However, the concomitant impact of postoperative tumor volume and eloquent location on OS has yet to be(More)
