Hypoglossal nerve examination

The hypoglossal nerve examination dominates the ipsilateral lingual muscle, which acts to extend the tongue forward and push it toward the opposite side. During the examination, the patient was stretched out to observe the deviation of the tongue, and the thickness of the tongue was not equal and trembled. During the examination, observe the position and shape of the tongue in the oral cavity, and then let the patient stick out the tongue to observe whether there is any deviation, muscle atrophy and fasciculation, and move to the left and right sides respectively. Finally, the doctor's finger is placed across the sputum. Muscle strength on both sides. There should be no food in the mouth during the examination. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Tips: Don't be too nervous when checking, and actively cooperate with the doctor's work. Normal value When the tongue is extended, the tongue is not skewed, and the thickness of both sides of the tongue is not equal and fluttering. Clinical significance Abnormal results: the tongue is skewed, the thickness of the tongue is not equal on both sides of the tongue and the sublingual nucleus lesions are prompted when the tremor is present. The deviation of the tongue to one side is common in cerebrovascular disease. People in need of examination: patients suspected of having neuronuclear lesions. Precautions Taboo before the test: Maintain a normal diet and adjust your mood. Requirements for inspection: 1. Be careful not to bite your tongue when you stick your tongue. 2. There should be no food in the mouth during the examination. Inspection process During the examination, observe the position and shape of the tongue in the oral cavity, and then let the patient stick out the tongue to observe whether there is any deviation, muscle atrophy and fasciculation, and move to the left and right sides respectively. Finally, the doctor's finger is placed across the sputum. Muscle strength on both sides. Whether it is supra-nuclear, nuclear or sublingual sublingual nerve damage, the tongue of one side is often biased to the temporal side in the mouth and when it is extended, the two sides are damaged, the movement of the tongue is completely lost, and the language is unclear. Difficulties, food movement in the mouth has obstacles and dysphagia, but nuclear and subnuclear damage, diaphragmatic muscle often atrophy, nuclear damage and fasciculation. Not suitable for the crowd Inappropriate crowd: Patients with severe tongue damage. Adverse reactions and risks Nothing.
