“…Below C6 the arteries are more laterally situated and are not at risk as long as a central approach is maintained [15]. Locating the cricoid cartilage at C6 and inserting the needle immediately next to the trachea avoids the carotid artery [17]. We have always been aware of the possibility of complications, however we have had no vascular injuries.…”

Background: One of the main difficulties in the treatment of dystonic anterocollis is the injection of the deep flexor muscles of the neck such as Longus Colli (LCo). The injection of the LCo has been regarded as difficult and potentially dangerous; since we published our anterior median approach, a number of questions about the precision and the safety of our technique have been raised by colleagues. Methods: 7 patients with anterocollis were injected, using our injection technique and when the needle was deemed to be in place, we used the ultrasound probe to determine what the needle had passed through, the depth of the tip of the needle and if the identified muscle was indeed LCo. Results: On the ultrasound section the LCo muscle is between 24 and 28 mm deep in the patients examined in this study. The location of the needle was confirmed by ultrasound and in most cases the needle was placed in the right axis but sometimes not deep enough. The EMG control made it possible to correct the depth in all cases. In most of the injections the needle traversed the thyroid. No acute incident occurred by this route of injection. Injections were performed between 22 and 28 mm deep. Discussion: From this study and based on a review of complications over 9 years experience with injecting LCo under EMG control using an anterior approach, we conclude that this technique is precise, safe and well tolerated. Summary (Highlights): The injection of the Longus Coli muscle for anterocollis has been regarded as difficult and potentially dangerous. This study showed, using ultrasound to determine the needle trajectory, that the anterior approach using EMG control is a precise, safe and well tolerated technique.

“…Nerve fibers emerge from the superior cervical ganglion to join the carotid nerve (which accompanies the internal carotid artery and its branches). In contrast, others from the stellate ganglion accompany the vertebral and basilar arteries and their branches up to the posterior cerebral arteries, where these join the innervation from the internal carotid artery [16][17][18]. Sympathetic innervations release adrenergic mediators that enhance sympathetic tone, a vital component of cerebral autoregulation.…”

Traumatic brain injury (TBI) and subarachnoid hemorrhage (SAH) are critical neurological conditions that necessitate specialized care in the Intensive Care Unit (ICU). Managing cerebral perfusion pressure (CPP) and mean arterial pressure (MAP) is of primary importance in these patients. To maintain targeted MAP and CPP, vasopressors and/or inotropes are commonly used. However, their effects on cerebral oxygenation are not fully understood. The aim of this review is to provide an up-to date review regarding the current uses and pathophysiological issues related to the use of vasopressors and inotropes in TBI and SAH patients. According to our findings, despite achieving similar hemodynamic parameters and CPP, the effects of various vasopressors and inotropes on cerebral oxygenation, local CBF and metabolism are heterogeneous. Therefore, a more accurate understanding of the cerebral activity of these medications is crucial for optimizing patient management in the ICU setting.

“…An unattached odontoid, known as an os odontoideum, can be identified on imaging when this fusion fails. The axis has much larger laminae compared to the rest of the cervical spine due to the transmission of forces applied superiorly [7]. Protruding from the laminae is a bifid spinous process, which serves as the attachment site for many muscles that connect to the occipital bone.…”

“…The "apical cave" is a crucial area between the odontoid process and the basion, and it is covered by neurovascular structures (i.e. coiled venous plexus, recurrent meningeal branches of C1 and C2, and the apical odontoid arterial arcade) [7].…”

With the advent and increased usage of posterior, lateral, and anterior surgical approaches to the craniocervical junction (CCJ), it is essential to have a sound understanding of the osseous, ligamentous, and neurovascular layers of this region as well as their three-dimensional (3D) orientations and functional kinematics. Advances in 3D technology can be leveraged to develop a more nuanced and comprehensive understanding of the CCJ, classically depicted via dissections and sketches. As such, this study aims to illustrate-with the use of 3D technologies-the major anatomical landmarks of the CCJ in an innovative and informative way. Photogrammetry, structured light scanning, and 3D reconstruction of medical images were used to generate these high-resolution volumetric models. A clear knowledge of the critical anatomical structures and morphometrics of the CCJ is crucial for the diagnosis, classification, and treatment of pathologies in this transitional region.
