Oral Ulcers and Cysts: Common Concerns and Treatments - Otolaryngology

Understanding oral ulcers and cysts can be quite complex, especially when symptoms persist or evolve over time. Based on your description, it appears that you have experienced a series of oral lesions, including ulcers and possibly cysts, which can arise from various causes. Let's break down the potential issues and treatments.


Oral Ulcers
Oral ulcers, commonly known as canker sores, can be triggered by several factors, including trauma (like biting the inside of your cheek), stress, hormonal changes, or certain food sensitivities. The fact that you initially felt a bump after biting your cheek suggests that the ulcer may have developed from that injury. These types of ulcers typically heal on their own within one to two weeks, but they can be painful and may recur.

In your case, the progression from a small ulcer to a water-filled blister (which you described as a "水泡") could indicate a few things. If the blister was caused by trauma, it might be a simple mucosal cyst or a mucocele, which occurs when a salivary gland is damaged and fluid accumulates. These are generally harmless and can resolve on their own, but if they persist, they may require drainage or surgical removal.


Cysts
Cysts in the oral cavity, such as mucoceles, are often caused by trauma or blockage of the salivary glands. They can appear as soft, fluid-filled bumps and may vary in size. If you suspect that the larger water-filled blister is a cyst, it’s essential to monitor it. If it does not resolve or if it becomes painful, you should consult a healthcare provider for further evaluation.


Diagnosis and Treatment
Given your symptoms, it’s crucial to have a thorough examination by a healthcare professional, preferably an oral surgeon or a dentist specializing in oral pathology. They may recommend imaging studies, such as an ultrasound or MRI, to assess the cyst's nature and determine if it is indeed a mucocele or something else.

For symptomatic relief of oral ulcers, consider the following treatments:
1. Topical Medications: Over-the-counter topical anesthetics like benzocaine can help numb the area and reduce pain.

2. Saltwater Rinses: Rinsing your mouth with warm salt water can promote healing and reduce inflammation.

3. Avoid Irritants: Stay away from spicy, acidic, or abrasive foods that might aggravate the ulcer.

4. Hydration: Ensure you are drinking plenty of fluids to keep your mouth moist and promote healing.


When to Seek Further Help
If the ulcer or cyst does not heal within two weeks, or if you notice any changes in size, color, or sensation, it is essential to seek further medical advice. Persistent lesions can sometimes indicate underlying conditions that may require more extensive investigation.


Conclusion
In summary, while many oral ulcers and cysts are benign and self-limiting, your ongoing symptoms warrant careful monitoring and possibly further evaluation. It’s essential to maintain open communication with your healthcare provider and report any changes in your condition. If you experience significant pain, difficulty eating, or any signs of infection (such as fever or increased swelling), seek immediate medical attention. Remember, your oral health is an integral part of your overall well-being, and addressing these concerns promptly can lead to better outcomes.
