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...

OBJECTIVE Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of the sinonasal cavity. Surgery has been and remains a mainstay of treatment for patients with this tumor. Open craniofacial resections have been the treatment of choice for many decades. More recently, experience has been growing with endoscopic approaches in the management of patients with ONB. The object of this study is to report the authors' experience over the past 11 years with ONB patients treated with purely endonasal endoscopic techniques...

BACKGROUND: Dermoid cysts are rare congenital teratomas that can occasionally rupture and cause chemical meningitis, neurological deficit, or hydrocephalus. Rarely, dermoid cysts in the pediatric population can rupture spontaneously and even more rarely rupture due to trauma. To date, there are only five documented cases of traumatic rupture of a dermoid cyst. A 2-year-old male presented with 5 days of left eye ptosis and ophthalmoplegia after suffering a fall and was found to have a ruptured left anterior clinoid dermoid cyst that was surgically resected...

Transsphenoidal microscopic pituitary surgery is an effective way of treating pituitary tumors. However, minimal invasive approach endoscopic transsphenoidal pituitary surgery has become much more prevalent these days. Endoscopic surgery resects the maximum tumour with less complications. As endoscopic surgery is much safer and less invasive as compared to the microscopic transsphenoidal surgery, selection of technology for the treatment of pituitary adenoma is becoming increasingly equivocal. The main aim of this systematic review was to assess the safety of endoscopic and microscopic transsphenoidal pituitary surgery in terms of postoperative complications...

Until recently, tumors of the clival region and ventral posterior cranial fossa were considered hard-to-reach and often inoperable via standard transcranial approaches. The introduction of minimally invasive methods combined with the endoscopic technique into neurosurgical practice has enabled removal of hard-to-reach tumors, including midline tumors of the ventral posterior cranial fossa. OBJECTIVE: To improve and introduce the extended endoscopic endonasal posterior (transclival) approach into clinical practice and to analyze the results of its application in surgical treatment of midline skull base tumors extending into the ventral posterior cranial fossa...

A malignant component in an epidermoid cyst is rare. We report an exceptionally rare case of a malignant melanoma arising in an epidermoid cyst located in the cerebellopontine (CP) angle. A 26-year-old woman presented with headache, vomiting, ataxia and difficulty in swallowing over the previous 3 months. The radiological finding suggested an epidermoid cyst and the lesion was excised. The histopathology confirmed a CP angle epidermoid cyst. Within 1 month of discharge, she developed hydrocephalus for which a ventriculo-peritoneal shunt was performed...
