Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Lateral canthotomy is a potentially eyesight-saving procedure when performed emergently for an orbital compartment syndrome. An orbital compartment syndrome results from a buildup of pressure behind the eye; as pressure mounts, both the optic nerve and its vascular supply are compressed, rapidly leading to nerve damage and blindness if the pressure is not quickly relieved. The medial and lateral...

Dorsal root ganglia (DRG) are structures containing the sensory neurons of the peripheral nervous system. When dissociated, they can be co-cultured with SC-like adipose-derived stem cells (ASC), providing a valuable model to study in vitro nerve regeneration and myelination, mimicking the in vivo environment at the injury site.

Minimally invasive surgical (MIS) procedures rely on anatomical references to localize structures not directly visible to the surgeon. This manuscript describes a combined method of plane-by-plane dissection and sectional anatomy of fresh-frozen specimens to locate the structures at risk during MIS procedures.

FAQs
Its functional significance depends on where it begins, the anatomical route it follows, and the tissues it reaches. A pathway ending in sensory structures supports communication from those tissues toward the central nervous system, whereas a pathway connected with motor targets may carry commands outward. Tracing these relationships helps interpret regional anatomy and predict consequences of disruption.
The name describes a position along the dorsolateral aspect of a region, but the relevant origin, course, and targets must be established for that specific anatomy. Without regional context, its sensory or motor contribution cannot be assigned precisely. Identifying the body region therefore prevents misinterpretation during dissection, examination, imaging review, or procedural planning.
Injury may interfere with electrical communication between the central nervous system and the nerve’s target tissues. The resulting findings depend on whether the affected fibers support sensation, movement, or both, as well as on the location of the damage along the pathway. Mapping the nerve provides an anatomical basis for relating altered sensation or pain to a suspected lesion.
It may represent either a peripheral nerve or a smaller nerve branch, so its anatomical scale and territory cannot be assumed from the name alone. A branch may serve a more limited target area than a larger parent nerve. Determining its origin and connections clarifies whether it should be interpreted independently or as part of a broader neural pathway.
Begin by identifying the relevant dorsolateral anatomical region, then trace the structure from its apparent origin along its course toward its target tissues. Record neighboring landmarks and the point at which sensory or motor communication is expected. This systematic mapping supports comparison with regional anatomy and helps identify structures that could be endangered during surgery.
Examination should focus on findings that correspond to the nerve’s mapped target structures, including changes in sensation, pain, or relevant movement when motor communication is involved. The examiner then compares these findings with the nerve’s origin and course. This anatomical correlation can help distinguish a regional nerve problem from a more central or unrelated cause.
Imaging interpretation depends on recognizing the nerve’s expected position and following its anatomical course through the relevant region. A reliable map provides a reference for assessing relationships with surrounding structures and for considering possible injury or abnormal sensory findings. Because the nerve’s exact pathway is region-dependent, imaging should be interpreted alongside established anatomical knowledge.
It becomes clinically important whenever a procedure occurs near its mapped course or target tissues. Knowing the pathway helps clinicians plan regional anesthesia and anticipate whether a surgical approach could affect neural communication. The same information supports evaluation after a procedure if pain, altered sensation, or suspected nerve injury develops in the relevant region.
