Article
Objective: Pain control is an important topic that has not been extensively studied in patients undergoing endoscopic skull base surgery (ESBS). The purpose of this study is to identify opioid requirements after ESBS and the risk factors predictive of increased use. Methods: This study was a retrospective review of all patients undergoing ESBS a...
Article
Objective There has been a significant expansion in endonasal endoscopic skull base surgery (EES) that has been used to address a wide range of intracranial and sinonasal pathologies. Although there exists a large amount of literature on approaches and patient outcomes, there is a paucity of data describing ergonomics in this field. Our goal was to...

Background: Meningiomas are the most common adult primary intracranial tumors in the United States. Despite high recurrence rate of atypical and malignant subtypes, there is no approved drug indicated specifically for meningioma. Since the majority of meningiomas exhibit high density of somatostatin receptors subtypes, somatostatin analogs have bee...
Article
Objective The influence of graft type (non-autologous versus autologous) on surgical outcomes in endoscopic anterior skull base (EASB) reconstruction is not well-understood. This review systematically evaluated rates of post-operative complications of EASB repairs that utilized autologous or non-autologous grafts. Methods Original studies reportin...
Article
Objective: For symptomatic nonsecreting pituitary adenomas (PAs), resection remains a critical option for treatment. In this study, the authors used a large-population national database to compare endoscopic surgery (ES) to nonendoscopic surgery (NES) for the surgical management of PA. Methods: The National Cancer Database was queried for all pa...
Article
Background: Pituitary apoplexy (PA) can manifest with visual and endocrine defects. The literature lacks strong support for either surgical or conservative management with respect to symptomatic improvement of these deficits. This meta-analysis compared visual and endocrine outcomes in conservative and surgical treatment of PA. Methods: A system...

Background Meningiomas are the most common adult primary intracranial tumors in the United States. Despite, high recurrence rate of atypical and malignant subtypes, there is no approved drug indicated specifically for meningioma. Majority of meningiomas exhibit high density (70%) of somatostatin receptors subtypes, and somatostatin analogs have bee...
Article
Background: Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, represents up to 3% of all sinonasal neoplasms. Hyams histologic grading is a promising tool in predicting metastases and establishing prognoses for this complex tumor. Methods: A systematic literature search was performed in the PubMed, Ovid MEDLINE, and Cochrane da...
Article
Background: Pituitary apoplexy (PA) is defined by hemorrhage and necrosis of the pituitary gland, often acute in onset, and frequently in the setting of an existing pituitary adenoma. Our objective was to conduct a meta-analysis of the available literature on vision outcomes following surgical intervention for PA on the basis of the timing from ap...
Article
OBJECTIVE C1–2 is a highly mobile complex that presents unique surgical challenges to achieving biomechanical rigidity and fusion. Posterior wiring methods have been largely replaced with segmental constructs using the C1 lateral mass, C1 pedicle, C2 pars, and C2 pedicle. Modifications to reduce surgical morbidity led to the development of C2 lamin...

Background and purpose: The World Health Organization has recently placed new emphasis on the integration of genetic information for gliomas. While tissue sampling remains the criterion standard, noninvasive imaging techniques may provide complimentary insight into clinically relevant genetic mutations. Our aim was to train a convolutional neural...

Background: Neurosurgery inpatients are oftentimes critically ill, and face significant stress, post-operative pain, and/or emotional distress. As a result, the use of non-pharmacologic, alternative therapies as adjuncts in surgical care may benefit this patient population. Hospital economics related to integrative services may also provide additi...
Article
BACKGROUND Esthesioneuroblastoma (ENB) is a rare malignant neoplasm that can be treated with open or endoscopic skull base approaches. We compared both approaches and present our outcome data. METHODS A retrospective review from 2007 through 2017 yielded 12 ENB patients. Kadish and TNM stage, Hyams grade, Ki-67, adjuvant chemoradiation, and resect...
Article
Meningioma is the most common primary intracranial tumor in adults. Thorough majority of tumors are slow growing, many patients fail first-line treatments with surgery and/or radiation. Others are poor surgical candidates for definitive surgical resection due to their age, tumor location or associated medical comorbidities. Few targeted therapies a...
Article
Epidermoids represent ~1% of all intracranial tumors, with up to half located in the CP angle. Though histologically benign, they often permeate the subarachnoid space and envelop surrounding neurovascular structures, making complete resection difficult. A variety of microscopic and endoscopic approaches have been described to gain access to these...

Study Design Prospective study. Objective Because single-level disk arthroplasty or arthrodesis in the lower subaxial spine improves headaches after surgery, we studied whether this effect may be better appreciated after two-level arthroplasty. Methods We performed an independent post hoc analysis of two concurrent prospective randomized investig...

Study Design Retrospective case series. Objective Diffuse idiopathic skeletal hyperostosis (DISH) or Forestier disease involves hyperostosis of the spinal column. Hyperostosis involving the anterior margin of the cervical vertebrae can cause dysphonia, dyspnea, and/or dysphagia. However, the natural history pertaining to the risk factors remain un...
Article
Failed back surgery syndrome (FBSS) is a prevalent, debilitating condition that affects the quality of life of many patients. The role of peridural fibrosis in FBSS continues to be a source of controversy. The authors report an association between peridural fibrosis and tactile allodynia, but not neurological dysfunction in a rodent cauda equine cr...
Article
Postsurgical infection is one of the greatest potential morbidities of ventriculoperitoneal shunt surgery. The majority of infections can be linked to contamination with skin flora at the time of surgery, a phenomenon that has been well described. However, there is a paucity of literature regarding infection with nontuberculous mycobacteria. The au...
Article
Locomotor impairments after spinal cord injury (SCI) are often assessed using open-field rating scales. These tasks have the advantage of spanning the range from complete paralysis to normal walking; however, they lack sensitivity at specific levels of recovery. Additionally, most supplemental assessments were developed in rats, not mice. For examp...
Article
Juvenile myoclonic epilepsy is a common subtype of idiopathic epilepsy accounting for 4-11% of all epilepsies. We reported previously significant evidence of linkage between chromosome 6p12-11 microsatellites and the clinical epilepsy and EEG traits of JME families from Belize and Los Angeles. To narrow the JME region, we ascertained and genotyped...
