Specialist Assessment and Treatment of Salivary Cysts
A mucocele is a common, benign swelling that develops when a minor salivary gland becomes blocked or damaged, leading to a build-up of saliva beneath the surface of the lining of the mouth.
They most frequently occur on the lower lip, but can also arise on the inner cheek, tongue, or floor of the mouth.
What Is a Mucocele?
Mucoceles form when saliva leaks into surrounding tissue or becomes trapped due to duct obstruction.
They typically appear as:
- A soft, fluid-filled swelling
- A bluish or translucent lump
- A lesion that may fluctuate in size
- A painless but noticeable bump
They may develop following minor trauma (such as lip biting) or arise without a clear cause.
When Treatment Is Recommended
Small mucoceles may occasionally resolve on their own.
However, treatment is often advised if the lesion:
- Persists for several weeks
- Repeatedly enlarges or ruptures
- Interferes with eating or speaking
- Is prone to trauma (e.g. lip biting)
- Causes cosmetic concern
Persistent lesions rarely resolve definitively without treatment.
The Procedure
Definitive treatment involves surgical excision.
- The mucocele is removed along with the associated minor salivary gland
- This reduces the risk of recurrence
- The procedure is typically performed under local anaesthetic
Special care is taken to identify and remove the underlying gland, rather than simply draining the swelling, which would result in recurrence.
Recovery
Recovery is usually straightforward.
- Mild swelling or discomfort settles within a few days
- Healing inside the mouth is typically uncomplicated
- Most patients return to normal eating within a few days to a week
Outcomes
Excision of a mucocele with the associated gland is highly effective.
Patients can expect:
- Resolution of the swelling
- Low recurrence rates when the gland is removed
- Minimal long-term impact
Risks and Considerations
Potential risks include:
- Minor bleeding or infection (uncommon)
- Recurrence if gland tissue is not fully removed
- Temporary discomfort at the surgical site
- Altered lip contour (uncommon)
- Altered lip sensation (usually temporary)
When to Seek Advice
Any persistent lump within the mouth should be assessed—particularly if:
- It does not resolve
- It changes in size
- It is repeatedly traumatised
Consultation
A consultation allows confirmation of the diagnosis and discussion of treatment options.
