A Case of Improved Idiopathic Isolated Hypoglossal Nerve Palsy without Use of Steroid / 계명의대학술지

ABSTRACT

The hypoglossal nerve palsy receives only brief mention in most textbooks and compared with other cranial nerve palsies, 12th nerve palsy is much less common. A literature review revealed that in most cases, isolated hypoglossal nerve palsy indicates the presence of an intracranial or extracranial space occupying lesion, head and neck injury, vascular abnormality, infection, autoimmune disease or neuropathy. Reports of idiopathic cases are rare and treated with steroid therapy. We report a 38-year-old woman with isolated hypoglossal nerve palsy improved spontaneously without steroid use. Considering our experience with isolated hypoglossal nerve palsy, we believe that no therapy is required in the patients with hypoglossal nerve palsy of probably idiopathic causes.
