Persistent Tongue Ulcer in Child: Causes and Treatment Options - Otolaryngology

Persistent tongue ulcers in children can be a distressing condition, both for the child and the caregivers. The case you described involves a third-grade boy who has been suffering from a painful ulcer on his tongue for over a month, which has not improved despite treatment with antibiotics and pain relief medications. This situation raises several important considerations regarding potential causes, treatment options, and the need for further evaluation.


Potential Causes
1. Viral Infections: One of the most common causes of tongue ulcers in children is viral infections, such as herpes simplex virus (HSV). While the initial diagnosis may have suggested herpes, the persistence of the ulcer and the lack of improvement with antiviral treatment could indicate a different underlying issue.

2. Aphthous Stomatitis: This condition, commonly known as canker sores, can cause painful ulcers in the mouth, including the tongue. The exact cause is often unknown, but factors such as stress, certain food sensitivities, or nutritional deficiencies (like vitamin B12, folate, or iron) may play a role.

3. Bacterial Infections: Secondary bacterial infections can occur if the ulcer is not healing properly, leading to further complications such as pus formation and bleeding.

4. Immune System Disorders: If the child has an underlying immune deficiency, this could lead to recurrent or persistent ulcers. Given that blood tests showed normal white blood cell counts, this may be less likely, but it is still a consideration.

5. Allergic Reactions or Irritants: Sometimes, certain foods, medications, or oral hygiene products can cause irritation leading to ulcer formation.


Treatment Options
1. Topical Treatments: For symptomatic relief, topical anesthetics (like benzocaine) can be applied to the ulcer to help alleviate pain. Additionally, protective pastes or gels can help shield the ulcer from irritation caused by food or saliva.

2. Oral Rinses: Antiseptic mouth rinses can help reduce bacterial load in the mouth and promote healing. Rinses containing ingredients like chlorhexidine may be beneficial.

3. Dietary Modifications: Avoiding spicy, acidic, or abrasive foods can help minimize irritation to the ulcer. Soft foods that are easy to swallow may be more comfortable for the child.

4. Nutritional Support: If a deficiency is suspected, dietary adjustments or supplements may be necessary. Consulting with a pediatrician or a nutritionist can provide guidance on appropriate dietary changes.

5. Pain Management: Over-the-counter pain relievers like acetaminophen or ibuprofen can help manage pain and discomfort, allowing the child to eat and sleep better.

6. Further Evaluation: If the ulcer does not improve with conservative measures, further evaluation by a pediatric specialist may be warranted. This could include a referral to an oral surgeon or an immunologist to rule out any underlying conditions.

7. Laser Therapy: In some cases, procedures such as laser therapy may be considered to promote healing and reduce pain, especially if the ulcer is deep and persistent.


Conclusion
In summary, persistent tongue ulcers in children can arise from various causes, including viral infections, aphthous stomatitis, or even immune-related issues. Given the duration and severity of the symptoms in this case, it is crucial to follow up with a healthcare provider for a comprehensive evaluation and tailored treatment plan. Early intervention can help alleviate pain and prevent further complications, ensuring the child can return to a comfortable and healthy state.
