Understanding Ranula: When a Blocked Saliva Gland Causes Trouble
We’ve all experienced minor mouth irritations—a canker sore, a bitten cheek, or a temporary swollen gum. But what happens when a painless, fluid-filled lump appears under your tongue or along the floor of your mouth? This could be a ranula, a type of cyst caused by a blocked saliva gland. While not life-threatening, ranulas can cause discomfort, affect speech or eating, and sometimes signal an underlying issue with your salivary system. Let’s explore what ranulas are, why they occur, and how to address them effectively.

What Is a Ranula?
A ranula is a mucus-filled cyst that forms when a salivary gland or duct becomes blocked or damaged. The term comes from the Latin word rana (meaning “frog”), as the swelling often resembles a frog’s translucent underbelly. These cysts typically appear as bluish, soft lumps beneath the tongue or along the floor of the mouth. In rare cases, they may grow large enough to extend into the neck, a condition called a “plunging ranula.”
Salivary glands produce saliva, which aids digestion, protects teeth, and keeps the mouth moist. When a duct (the tiny tube carrying saliva) is blocked, saliva backs up, creating a fluid-filled sac. Unlike infections or abscesses, ranulas are usually painless unless they become infected or grow large enough to press on nearby structures.

Why Do Saliva Glands Get Blocked?
Salivary gland blockages can occur for several reasons:
1. Trauma or Injury: A bite to the tongue or cheek, dental procedures, or even habits like cheek-chewing can damage ducts.
2. Thickened Saliva: Dehydration, certain medications, or medical conditions like Sjögren’s syndrome can make saliva sticky, increasing blockage risks.
3. Salivary Stones (Sialoliths): Calcium deposits can form in glands, obstructing saliva flow.
4. Scarring or Inflammation: Previous infections or surgeries may leave scar tissue that narrows ducts.
In many cases, the exact cause remains unknown. Ranulas are most common in teens and young adults but can develop at any age.

Recognizing the Symptoms
Ranulas often appear suddenly and grow slowly over weeks. Key signs include:
– A soft, bluish lump under the tongue or in the floor of the mouth.
– Difficulty speaking, chewing, or swallowing if the cyst is large.
– A feeling of fullness or pressure in the affected area.
– Rarely, swelling in the neck (plunging ranula).
While most ranulas aren’t painful, complications like infection or rupture can cause redness, tenderness, or sudden fluid drainage. If left untreated, recurring blockages may lead to chronic swelling.

Diagnosing a Ranula
If you notice a persistent mouth lump, consult a dentist or ENT specialist. Diagnosis typically involves:
– Physical Examination: The cyst’s location and appearance often provide clues.
– Imaging: Ultrasound, CT scans, or MRI can confirm the diagnosis and rule out tumors or abscesses.
– Fine-Needle Aspiration: A small needle may withdraw fluid from the cyst to check for mucus content.
In most cases, imaging and a clinical exam are sufficient. Your doctor may also review your medical history to identify contributing factors like dehydration or autoimmune disorders.

Treatment Options: From Simple to Surgical
Treatment depends on the ranula’s size, location, and recurrence history. Options include:
1. Watchful Waiting
Small, asymptomatic ranulas may resolve on their own. Your doctor might recommend monitoring the cyst while maintaining good hydration and oral hygiene.
2. Marsupialization
For recurring or bothersome cysts, a minor procedure called marsupialization can help. The surgeon opens the cyst, drains the fluid, and stitches the edges to form a “pocket” that prevents reaccumulation. This is often done under local anesthesia.
3. Gland Removal
If blockages recur due to a damaged gland, surgical removal of the affected gland (usually the sublingual gland) may be necessary. This is a last-resort option but has a high success rate.
4. Laser Therapy or Sclerotherapy
Emerging treatments like laser ablation or injecting sclerosing agents (to shrink the cyst) show promise but are less commonly used.
Avoid puncturing the cyst yourself, as this can lead to infection or recurrence.

Preventing Future Blockages
While not all ranulas can be prevented, these habits support salivary health:
– Stay Hydrated: Drink plenty of water to keep saliva thin and flowing.
– Practice Oral Hygiene: Brush, floss, and rinse regularly to reduce infection risks.
– Avoid Repetitive Trauma: Break habits like cheek-chewing or tongue-piercing.
– Treat Underlying Conditions: Manage issues like Sjögren’s syndrome or chronic dry mouth with your doctor.

When to Seek Help
Most ranulas are harmless, but consult a healthcare provider if:
– The lump persists for more than 2–3 weeks.
– You experience pain, rapid growth, or difficulty swallowing.
– Swelling spreads to the neck.
Early intervention reduces complications and improves outcomes.

Final Thoughts
A ranula might look alarming, but it’s usually a manageable condition. Understanding the role of saliva glands, recognizing symptoms early, and seeking professional care can help you address the issue before it affects your daily life. If you spot a mysterious bump in your mouth, don’t panic—but don’t ignore it either. With modern treatments, even stubborn blockages can be resolved, restoring comfort and function to your smile.
