Objectives  Superior semicircular canal dehiscence (SSCD) results from a defect in the middle cranial fossa floor. One challenge during SSCD repair is the lack of a consistent landmark. This study proposes a reference point above the external auditory canal at the level of the zygoma as the inferior craniectomy edge during surgery. Design  This is a retrospective review of patients with SSCD. Setting/Participants  A total of 72 cases of SSCD in 60 patients were repaired via a middle fossa approach at a single institution...

BACKGROUND: Decompressive craniectomy (DC) is often performed in conjunction with evacuation of intracranial hemorrhage (ICH) to control intracranial pressure (ICP) in patients with a traumatic brain injury (TBI). The efficacy of DC in lowering ICP is well established, however, its effect on clinical outcomes remains controversial. The aim of our study is to assess outcomes in TBI patients undergoing decompressive craniectomy (DC) vs. craniotomy only (CO) for the evacuation of intracranial hemorrhage...

BACKGROUND: Hemangioblastomas (HGBs) are the most common primary intra-axial posterior fossa tumor in adults. Although spontaneous hemorrhage of these tumors is exceedingly rare, despite their vascular nature, we describe a case of recurrent hemorrhage with associated tonsillar herniation, and demonstrate that a surgical approach can provide a suitable outcome. CASE DESCRIPTION: A 54-year-old female with von Hippel-Lindau (VHL) syndrome presented with acute loss of consciousness and Glasgow Coma Scale (GCS) was 4...

INTRODUCTION: Pure choriocarcinoma of the testes is a rare, aggressive germ cell tumor (GCT) that can metastasize to the brain. Although its prognosis has improved with the development of cisplatin-based chemotherapy regimens, cerebral metastases are prone to hemorrhage and are associated with high morbidity. Here, we present two cases of testicular choriocarcinoma with cerebral metastasis and discuss potential pitfalls in their diagnosis and management. We also review cases in the literature that feature these rare lesions...

Iatrogenic cranial nerve palsies can rarely complicate neurosurgical, oral maxillofacial, and otolaryngological procedures. Among the most serious complications of cranial nerve palsy is upper airway obstruction, which is life threatening. We present a case of multiple cranial nerve palsies evolving rapidly in a rostrocaudal stepwise fashion after infiltration of lidocaine to repair a cerebrospinal fluid leak in a patient postoccipital craniectomy. This led to hypoxic respiratory failure requiring mechanical ventilation before resolving spontaneously...

BACKGROUND: Retromastoid craniectomy (RSC) is a cardinal surgical approach used to access the posterior fossa. Hydroxyapetite bone cement (HBC) is frequently employed for cranioplasty in efforts to prevent cerebrospinal fluid (CSF) leak, whilst maintaining low complication rates and good cosmetic satisfaction. The authors aim to determine the safety and effectiveness of HBC for reconstruction RSC used for treatment of various cranial nerves disorders. METHODS: The authors conducted a retrospective one-center two surgeons review of 113 patients who underwent RSC filled with HBC for the treatment of cranial nerve disorders...

Dr. Norman Chater, a University of California, San Francisco-trained microvascular neurosurgeon, dedicated his career to the development of surgical bypass techniques. His work contributed to advancements in microvascular anatomy and the development of cerebral revascularization techniques. He identified Chater's point, an extracranial landmark that marks the posterior extent of the Sylvian fissure, which upon craniectomy reliably exposes vessels of the angular gyrus, vasculature found to be most appropriate for bypass procedures due to their accessibility and vascular diameter...

OBJECTIVE In severe traumatic brain injury (TBI), the effects of decompressive craniectomy (DC) on brain tissue oxygen pressure (PbtO2) and outcome are unclear. The authors aimed to investigate whether changes in PbtO2 after DC could be used as an independent prognostic factor. METHODS The authors conducted a retrospective, observational study at 2 university hospital ICUs. The study included 42 patients who were admitted with isolated moderate or severe TBI and underwent intracranial pressure (ICP) and PbtO2 monitoring before and after DC...

INTRODUCTION: Traumatic spinal subdural hematoma involving the retroclival region and upper cervical spine is a rare pathology. To our knowledge, there have only been two prior cases in an adult trauma patient. We describe a patient with pre-existing Chiari 1 malformation, who recently sustained a unilateral Type 1 OCF (occipital condyle fracture) with associated disruption of the tectorial membrane and transverse ligament, that returned with a retroclival subdural hematoma extending down to C7, causing spinal cord compression and symptomatic obstructive hydrocephalus...
