Abstract
The hypoglossal nerve HN gives motor innervation to the intrinsic muscles of the tongue and to the genioglossus styloglossus and hypoglossus muscles The hypoglossal nerve can be divided into five segments the medullary cisternal skull base carotid space and sublingual segments Hypoglossal nerve palsy is often associated to other cranial nerve palsy or to a brainstem lesion Isolated hypoglossal nerve palsy IHNP is uncommon and has been mainly described in single case reports Most cases have a tumorous or iatrogenic cause The other IHNP etiologies are less well known and their frequencies often underestimatedAll procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Heklsinki declaration and its later amendments or comparable ethical standards
