Introduction: Hypoglossal nerve is formed from the hypoglossal nucleus situated in the medulla oblongata. It leaves the medulla through the anterolateral sulcus. It carries general somatic efferent fibres that means purely motor in nature. Landmark of the nerve is of paramount importance to avoid the damage during neck surgeries. Variations in the extracranial course may lead to the iatrogenic injuries to the important structures related to it. In our case, we found an aberrant branch from the hypoglossal nerve.

Conclusion: Very few cases are reported of an aberrant hypoglossal nerve. Therefore, finding such rare cases is helpful for the surgeon before the operative procedures in the region to prevent serious injuries leading to neurological deficits
