Because laminectomy has been shown to predispose patients to kyphosis, laminoplasty and hemilaminectomy are the most widely used approaches to preserve the posterior tension band (PTB). However, these techniques are not devoid of complications. To overcome these issues, the authors modified a previously described technique to preserve the PTB while removing various types of intradural lesions.

DVA-associated hemorrhage within the CST could be safely removed with modern awake mapping techniques. This technique allowed the patient to rapidly improve his hand function. Small venous channels found inside the hematoma cavity could be coagulated without signs of ischemia or venous infarction.

Micromirrors proved to be useful in enhancing the visualization of neurovascular structures and pathology residuals within deep-seated surgical fields without the need for fixed brain retraction. Their cost-effectiveness and easy learning curve constitute solid reasons for advocating a revitalization of this “old but gold” tool in neurosurgery.

Split‐type C1 lateral mass fractures have a propensity for progressive fracture displacement. Since almost all cases end up showing progressive fragment diastasis, many authors recommend early surgical treatment. However, placing a C1 lag screw through a C1 split fracture is a challenging task.

Optic nerve mobilization after optic foraminotomy proved to be a safe and relatively easy technique for exposing and treating superior carotideophthalmic aneurysms.

Surgery of the cervical spine under conscious sedation has been rarely reported in the literature. The main indications are the lack of neurophysiological monitoring and surgery in patients with high cardiovascular risk. To date, no reports of awake C1–2 instrumentation have been published in the English-language literature.
