the Nuchal Lines as anatomic landmarks to dissect the muscles in the far lateral approach
World Neurosurgery, 2018Co-Authors: Alvaro Campero, Juan F Villalonga, Ramiro Lopez Elizalde, Pablo AjlerAbstract:Background A critical step in the far lateral approach (FLA) is exposure of the V3 segment of the vertebral artery, located deep in the suboccipital triangle (SOT). Safe exposure of the SOT is achieved by means of a plane-by-plane dissection, which carries the risk of devascularization. A suitable alternative is to lift a cutaneous muscle flap including the 3 first muscle planes and leave the deepest plane (SOT) attached to the skull base. To achieve this, it is necessary to have superficial anatomic landmarks to help identify the cleavage site. We describe the use of the Nuchal Lines as a safe, effective, and reproducible method to dissect the muscles to expose the SOT and vertebral artery. Methods Eight adult cadaveric heads, fixed with formaldehyde and injected, were studied. On both sides, FLA was simulated by using the Nuchal Lines as anatomic landmarks to expose the SOT. This technique was later applied on 10 patients requiring FLA. Results Anatomic dissections confirmed identification, by means of the Nuchal Lines, of a cleavage site, which made it possible to separate the deepest muscle plane from the rest of the flap. This technique was successfully applied in 10 patients undergoing FLA. Conclusions The Nuchal Lines allow dissection of muscles in 2 groups, one superficial and the other deep (SOT), which remains attached to the skull base. The V3 segment of the vertebral artery is easily exposed.

bony tubercle at external occipital protuberance and prominent ridges
Journal of Craniofacial Surgery, 2012Co-Authors: Rajani SinghAbstract:During the examination of skulls in the osteology laboratory of the Department of Anatomy, CSM Medical University, Lucknow, UP, India, a skull was detected having exostosis projecting from the external occipital protuberance along with prominent superior Nuchal Lines appearing as ridges. Measurements of the tubercle were taken by vernier calipers, and possible causes and clinical implications were analyzed.The length of this tubercle was 8 mm; width was 6 mm and thickness 1.5 mm. The superior Nuchal Lines appeared as prominent ridges. The height of the ridges was 5 mm on both sides; the thickness was 10 mm and 8 mm, respectively, on both the right and left sides. The length of the ridges was 4.8 cm on the right side and 4.4 cm on the left side.The tubercle may cause occipital headache in general but especially in tree climbers and basketball/volleyball players during vertical biomechanical movements of the neck. The knowledge of this tubercle is of paramount importance to anatomists, neurosurgeons, sports physicians, radiologists, forensic experts, and anthropologists.
