Abstract :

Introduction: Hypoglossal nerve palsy (HNP) is rare, and presents as deviation of the tongue to the affected side on protrusion, often alongside wasting and fasciculation of tongue musculature1. Objectives: To discuss a 66-year-old female with an incidental finding of HNP, and review the literature and differential diagnoses. Methods: The patient complained of left sided facial pain, displaying symptoms of myofascial pain in the muscles of mastication, and conservative advice was given. Further examination revealed deviation of the tongue to the left on protrusion and a sinister diagnosis could not be excluded. Magnetic Resonance Imaging (MRI) of the head, neck and internal acoustic meatus revealed no abnormality in the medulla or hypoglossal canal or nerve pathway. The patient was referred to the Ear, Nose and Throat department where she underwent nasal endoscopic examination which revealed mild thickening of the posterior lingual tissues but no suspicious features or obvious causes for HNP. A literature search was undertaken to review the differential diagnoses for HNP: four case-series were compared, totaling 361 cases2-5. Results: No cause for the nerve palsy has been identified; the patient will be reviewed routinely. Differential diagnoses include: tumours such as squamous cell carcinoma, chordoma and glioma(34%), iatrogenic(21%), idiopathic(11%) and rarely multiple sclerosis, stroke, inflammation, and tubercular meningitis2-5. Conclusion: HNP is the abnormality of imbalanced action of the genioglossus muscles leading to tongue deviation towards the weak side on protrusion. There are a wide number of differential diagnoses for HNP reported, the most common being neoplasm, iatrogenic damage and idiopathic.
