Persistent idiopathic unilateral hypoglossal nerve palsy

Bagán-Sebastián JV, Milián-Masanet MA, Peñarrocha-Diago M, Lloria de Miguel E. Persistent idiopathic unilateral hypoglossal nerve palsy. J Oral Maxillofac Surg. 1998 Apr;56(4):507-10.


Hypoglossal nerve palsy (HNP) can occur when a lesion is located in the bulbar nucleus or distal to it. In such cases, the tongue, when at rest within the oral cavity, deviates toward the unaEected side. However, when protruded, the tongue deviates toward the affected side under the influence of the intact genioglossus.
Fasciculations may be observed in the paretic region, although over time the affected hemitongue undergoes progressive atrophy.
