The coronavirus disease 2019 (COVID-19) pandemic has infected more than 13 million people on a global scale and claimed more than half million deaths across 213 countries and territories. While the focus is currently on recovery from the pandemic, the disease has significantly changed the way we practice medicine and neurosurgery in New York City and the United States. Apart from the emergency cases, several health systems across the country have similarly started to perform elective surgeries. Although COVID-19 screening and testing guidelines have been proposed and adopted by many hospitals, these may not adequately protect the operating room personnel who are in proximity to the patient for prolonged periods. There are concerning reports of especially high transmission rates of COVID-19 in transmucosal head and neck procedures conducted by otolaryngologists and neurosurgeons, despite attempts at wearing what constitutes appropriate personal protective equipment. ⋯ With the rising concerns regarding airborne spread of the virus, we expect that these precautions will prove highly useful as we enter the recovery phase of this pandemic and hospitals attempt to prevent a return to widespread infection. In addition, its availability and cost effectiveness make this technique especially attractive to practical use in centers with limited resources.

This report describes a technique for an immediate mechanical intervention using a familiar tool for emergency physicians and trauma surgeons to temporize acute epidural bleeding with mass effect. The Monro-Kellie Doctrine suggests that immediate removal of some blood will reduce intracranial pressure and mitigate some of the deleterious effects until the neurosurgeon can respond. ⋯ Bedside craniosotmy with an intraosseous drill can allow for immediate temporizing of a large epidural hemorrhage and be applied by emergency physicians and/or trauma specialists when neurosurgical consultation is delayed. Serial aspirations should be performed when hemorrhage is ongoing and until definitive evacuation is performed.

Some patients with Chiari malformation type I (CM-1) present with a positive family history of CM-1, the significance of which remains unknown. We aimed to study whether family history affects the clinical presentation characteristics and surgical outcome of adult patients with CM-1. ⋯ Presentation characteristics are comparable between patients with and without a family history of CM-1. Patients with a positive family history may be less likely to respond favorably to suboccipital decompression.

Colloid cysts of the third ventricle are rare benign lesions, which amount to approximately 1% of all intracranial tumors. Because these lesions grow predominantly in the anterior aspect of the third ventricle, they may cause the occlusion of the foramina of Monro, generating obstructive hydrocephalus. Surgery is mandatory in cases of large cysts and/or in symptomatic patients. Among the different surgical strategies described in colloid cysts surgery, the microsurgical transcallosal approach still constitutes the procedure of choice in many centers. In this study, we describe a modified microsurgical transcallosal approach, the interhemispheric transgenual approach, in a series of 13 consecutive patients operated on for colloid cysts of the third ventricle. ⋯ In our experience, the interhemispheric transgenual approach has been effective in providing complete colloid cyst removal with minimal risk of vascular and parenchymal damage. Further studies are required to confirm its efficacy in improving the overall outcome of the microsurgical transcallosal approach.
