Abstract

The hypoglossal canal is a permanent element of the human skull (Wysocki et al. 2004). The hypoglossal canal is situated occipital bone (Sakamoto 2019). Variations can be found in this canal. Sometimes it is divided by a spicule of a bone leading to a variant as a double hypoglossal canal (Zaidi, Gupta, and Usman 2011). Knowledge of variations in anatomy is important in both surgery and anatomy.
