Introduction
Tongue deviation, when accompanied by symptoms such as unilateral limb weakness or slurred speech, may be a precursor to stroke. If the patient has a prior history of mandibular trauma, it may result from hypoglossal nerve atrophy. In cases where tongue deviation occurs suddenly without any identifiable underlying cause, it may indicate an intracranial space-occupying lesion—such as a brain tumor.
Tongue deviation may be a sign of conditions such as stroke, hypoglossal nerve injury, or intracranial space-occupying lesions.
1. Stroke
If tongue deviation occurs along with other abnormalities such as weakness in one side of the body, dizziness, or slurred speech, it may indicate an impending stroke. This is more commonly seen in patients with hypertension or diabetes. Immediate medical attention at a hospital is necessary to prevent serious consequences.
2. Hypoglossal Nerve Injury
If a patient has a history of jaw trauma or surgery and develops tongue deviation, it may be due to damage and subsequent atrophy of the hypoglossal nerve. Treatment typically involves taking neurotrophic medications as directed by a physician, including commonly used drugs such as vitamin B6 and methylcobalamin.
3. Intracranial Space-Occupying Lesions
If a patient suddenly develops tongue deviation without any apparent underlying cause, it could be due to an intracranial space-occupying lesion, such as a brain tumor. Surgical removal is usually required, followed by determining the appropriate treatment plan based on pathological findings.
