An Easy Way of Identification and Protection of the Hypoglossal Nerve during Neck Dissection for Head and Neck Cancer

Understanding the anatomical relationship between the Hypoglossal Nerve (HN) and the Facial Vein (FV) is crucial during neck dissections for head and neck cancer. The consistent placement of the HN beneath the FV provides a reliable anatomical landmark, aiding in the preservation of nerve function and reducing surgical complications. This paper reviews the anatomical pathway of the HN, its clinical implications, and surgical observations from 87 cases. Techniques for protecting the HN during neck dissection are also discussed, emphasizing the importance of precise surgical planning to avoid postoperative complications.
