Introduction: Preservation of the spinal accessory nerve during neck dissection should be the rule rather than the exception. Despite the presence of many described techniques to locate the nerve, a tedious dissection is often required; as a consequence, it remains vulnerable to damage.
Method: We describe a novel method, not previously reported, based on identifying a constant vein which crosses the nerve. This aids in the nerve's early identification.
Conclusion: Our method enables the surgeon to locate the nerve precisely and to avoid damage to it, thereby maximizing post-operative function.
