Swelling and Sensitivity Under the Tongue: ENT Insights - Otolaryngology

More Info

---

Swelling and sensitivity under the tongue can be concerning symptoms, and they may arise from various underlying conditions. As an ENT specialist, I can provide insights into potential causes and recommend steps for evaluation and management.


Possible Causes of Swelling and Sensitivity Under the Tongue
1. Sublingual Gland Issues: The sublingual glands, located beneath the tongue, can become swollen due to infections, blockages, or inflammation. A common condition is sialadenitis, which is an infection of the salivary glands. This can lead to swelling and tenderness, especially if there is a stone blocking the duct.

2. Allergic Reactions: Allergies can cause localized swelling in the mouth, including under the tongue. This could be due to food allergies, oral hygiene products, or environmental allergens. If you have recently introduced new foods or products, consider whether they might be the cause.

3. Infections: Viral infections, such as herpes simplex virus, can cause lesions and swelling in the oral cavity. Bacterial infections can also lead to localized swelling and sensitivity.

4. Cysts or Tumors: While less common, cysts (such as ranulas) or benign tumors can develop under the tongue, leading to swelling. These are usually painless but can cause discomfort depending on their size and location.

5. Oral Lichen Planus: This is a chronic inflammatory condition that can affect the mucous membranes of the mouth, leading to white patches, swelling, and sensitivity.

6. Trauma or Irritation: If you have bitten your tongue or experienced irritation from dental appliances, this can lead to localized swelling and sensitivity.


Recommendations for Evaluation
1. Clinical Examination: A thorough examination by an ENT specialist or a dentist is crucial. They will assess the area for signs of infection, blockage, or other abnormalities.

2. Imaging Studies: If a significant issue is suspected, imaging studies such as ultrasound or MRI may be warranted to visualize the glands and surrounding structures.

3. Allergy Testing: If allergies are suspected, consider consulting an allergist for testing to identify potential triggers.

4. Salivary Gland Function Tests: These tests can help determine if the salivary glands are functioning properly and if there are any blockages.

5. Biopsy: In cases where a cyst or tumor is suspected, a biopsy may be necessary to determine the nature of the growth.


Management Strategies
- Hydration: Ensure you are well-hydrated, as this can help with salivary gland function.

- Warm Compresses: Applying a warm compress to the area may help reduce swelling and discomfort.

- Avoid Irritants: If you suspect that certain foods or products are causing irritation, try to avoid them.

- Medications: Depending on the underlying cause, medications such as antihistamines for allergies or antibiotics for infections may be prescribed.


Conclusion
Swelling and sensitivity under the tongue can result from various conditions, ranging from benign to more serious issues. It is essential to seek medical evaluation to determine the exact cause and appropriate treatment. If your symptoms persist or worsen, do not hesitate to consult with an ENT specialist for further assessment and management.
