Fracture of the occipital condyle is a rare injury that can be easily overlooked. Palsies of lower cranial nerves can be the only symptom of the fracture. We report a patient with isolated post-traumatic hypoglossal nerve palsy who developed hypoglossal nerve palsy within 2 months after a car accident, indicating that the acute trauma itself did not damage the hypoglossal nerve. Most likely the palsy is caused by pressure to the nerve prior to the entry or within the hypoglossal canal. Since, in the present case, the fracture was stable and the patient showed only moderate neurological deficits, the operation was deferred.
枕髁骨折是一种罕见的损伤，很容易被忽视。下颅神经麻痹可能是该骨折的唯一症状。我们报告一例孤立性创伤后舌下神经麻痹患者，该患者在车祸后2个月内出现舌下神经麻痹，提示急性创伤本身并未损伤舌下神经。麻痹很可能是由于舌下神经管入口处或管内神经受到压迫所致。在本病例中，由于骨折稳定且患者仅表现出中度神经功能缺损，因此推迟了手术。
