PURPOSE: Optic pathway gliomas (OPGs) are low-grade neoplasms that primarily affect children. The management of OPGs remains controversial. Reports on the use of the endoscopic endonasal approach (EEA) in OPGs are extremely limited, and no such reports exist on its utility for pediatric OPGs. Here, we report our results and experience with OPGs treated with the EEA. METHODS: We retrospectively reviewed the medical records of OPG patients who were treated surgically via the EEA at our institutions from 2015 to 2017...

The occurrence of cerebral vasospasm secondary to bacterial meningitis is relatively rare. Furthermore, there is no specific treatment cerebral vasospasm. Endovascular treatment may be essential for cases with the advanced clinical course. Balloon angioplasty or intra-arterial injection of verapamil, nicardipine, or nitroglycerin has been previously reported. We experienced successful treatment using intra-arterial infusion of fasudil hydrochloride. To our knowledge, this is the first case to report the intra-arterial injection of fasudil hydrochloride for treating cerebral vasospasm secondary to bacterial meningitis...

Importance: Infection after cochlear implantation is a rare but serious event that can lead to meningitis. There is no consensus on prevention of infection in these patients, and each center applies its own strategy. Objective: To describe the rates of major surgical site infection for patients undergoing cochlear implantation who receive prolonged antibiotic treatment compared with those who receive a single perioperative dose of antibiotic prophylaxis. Design, Setting, and Participants: Retrospective cohort study of patients who underwent cochlear implantation between January 1, 2011, and July 8, 2015, with a postoperative follow-up of 1 to 3 years...

During the past decade, tumor bed stereotactic radiosurgery (SRS) after surgical resection has been increasingly utilized in the management of brain metastases. SRS has risen as an alternative to adjuvant whole brain radiation therapy (WBRT), which has been shown in several studies to be associated with increased neurotoxicity. Multiple recent articles have shown favorable local control rates compared to those of WBRT. Specifically, improvements in local control can be achieved by adding a 2 mm margin around the resection cavity...

Introduction: Petroclival meningiomas are based on or arising from the petro-clival junction in upper two-thirds of clivus, medial to the fifth cranial nerve. This study focuses on the surgical experience in resecting large-giant tumors >3.5 in size predominantly utilizing middle fossa approaches. Material and Methods: 33 patients with a large or a giant petroclival meningioma (size >3.5 cm) were included. Clinical features, preoperative radiological details, operative findings, and postoperative clinical course at the follow-up visit were reviewed...

OBJECTIVES: Bacterial meningitis can cause a labyrinthitis. Consequences often are intracochlear soft tissue neoformation (cochlear obliteration) or intracochlear osteoneogenesis (cochlear ossification) and deafness. Cochlear implantation becomes challenging and hearing rehabilitation is complicated. This retrospective case-control-study aimed to find correlations between morphologic, electric and functional parameters. METHODS: The study group included children, who lost hearing due to a bacterial meningitis (n = 35 cases)...

PURPOSE: The clinical significance of postoperative pseudomeningocele formation following optic nerve sheath fenestration (ONSF) has not been fully characterized. A literature review identifies 9 previously published cases the authors believe demonstrate pseudomeningocele formation and approximately 19 other similar findings that were either transient or less defined blebs. This study was undertaken to more clearly define the clinical, radiographic, and histopathologic features associated with this entity...

BACKGROUND AND OBJECTIVES: Controversy related to the choice of surgical approach for vestibular schwannoma (VS) resection remains. Whether the retrosigmoid (RS) or translabyrinthine (TL) approach should be performed is a matter of debate. In the context of a lack of clear evidence favoring one approach, we conducted a retrospective study to compare the morbidity rate of both surgical approaches. Subjects and. METHODS: 168 patients underwent surgical treatment (2007-2013) for VS at our tertiary care center...

OBJECTIVE Numerous surgical procedures facilitate revascularization of the ischemic brain in patients with moyamoya disease. Dural inversion is a technique in which flaps of dura mater centered around the middle meningeal artery are inverted, encouraging the formation of a rich collateral blood supply. This procedure has been used in combination with encephaloduroarteriosynangiosis for more than 20 years at the authors' institution for the treatment of pediatric moyamoya disease. The objective of this study was to describe the clinical and radiographic outcomes for a cohort of consecutive pediatric moyamoya patients undergoing dural inversion...

PURPOSE: Most cases of non-traumatic nasal cerebrospinal fluid (CSF) leaks occur spontaneously without any obvious reason. Severe and life-threatening complications are possible consequences. Endoscopic repair is considered the gold standard; however, diagnosis and therapy of these CSF leaks stay challenging. METHODS: In this retrospective analysis, patients who presented with spontaneous nasal CSF leaks from 2006 to 2017 were included. Symptoms, diagnostics, localization of the skull base defect, surgical method, outcome, and postoperative treatment were recorded...

Background: Sphenoid wing meningiomas account for 20% of supratentorial meningiomas. The main supply of these tumors is provided by branches of the middle and accessory meningeal arteries. Surgical resection of meningiomas requires early tumor devascularization. Our objective is to present the role of transzygomatic approach plus mini-peeling of the anterior third of the middle fossa in the extradural identification and coagulation of branches of middle and accessory meningeal arteries involved in tumor supply...
