Oral mucoceles are among the most frequently encountered benign lesions in dental and oral medicine practice.
Despite their relatively innocuous appearance, they can be a source of concern for both patients and clinicians due to their recurrent nature, sudden appearance, and occasionally confusing clinical behavior.
These mucus-filled lesions, typically resulting from trauma to minor salivary glands, can vary in size, depth, and location—making accurate diagnosis and tailored management essential.
Recent studies have expanded our understanding of mucoceles, including their pathogenesis, differential diagnosis, and the success of both surgical and non-surgical treatment modalities.
With a notable prevalence in children and young adults, and a significant incidence in the lower lip, clinicians must stay updated on the latest minimally invasive and evidence-based approaches to improve patient care and minimize recurrence.
This professional guide, curated for the Ovidental global community, summarizes the most recent findings from the past five years and offers practical insights into the classification, presentation, diagnosis, and management of mucoceles in daily dental practice.
Pathogenesis and Classification
✔ Two main types
- Extravasation mucocele (≈ 84%): caused by trauma to salivary duct, leading to mucin spillage into surrounding tissues—commonly seen in lips, cheeks, and ventral tongue.
- Retention mucocele (≈ 16%): due to obstruction of the salivary duct, typically affecting older adults.
✔ Epidemiology
A 2021 Brazilian study reviewing 1,901 cases found a peak incidence in individuals aged 10–20, with a slight female predominance. The lower lip was by far the most common location.
Clinical Presentation
✔ Dome-shaped, fluctuant nodules with bluish or translucent appearance.
✔ Size ranges from a few millimeters to over 2 cm.
✔ Typically painless but may cause discomfort when chewing or speaking.
✔ Superficial mucoceles may resemble vesicles, ulcerate, and heal spontaneously—often recurring.
Diagnosis
✔ Clinical: Based on location, trauma history, and visual inspection (color, consistency, size).
✔ Histopathological: Shows mucin-filled cavity without epithelial lining, surrounded by granulation tissue—hallmark of extravasation mucoceles.
✔ Imaging: Ultrasound or CT is advised for deeper lesions or suspected ranulas to assess glandular involvement.
Treatment Options
(2020–2025 Update)
4.1 Surgical Excision
✔ Standard of care: Complete excision with surrounding minor salivary glands.
✔ Recurrence rate less than 10%, but higher when lesion size greater than 2 cm or in ventral tongue mucoceles.
✔ No significant difference between scalpel and laser excision in terms of recurrence, as confirmed in a 2021 systematic review.
4.2 Minimally Invasive Approaches
✔ Micro-marsupialization: Effective in pediatric patients, minimal trauma, good outcomes.
✔ Intralesional corticosteroids: Recent case reports show complete resolution in 2–4 weeks with no recurrence at 6 months.
✔ Sclerotherapy (Bleomycin): Shown to be highly effective for small ranulas, with complete healing reported in all 60 cases of a 2023 study.
4.3 Comparative Considerations
✔ Treatment should be individualized based on size, location, patient age, and recurrence history.
✔ Conservative approaches may be preferred in children before surgery is considered.
Prevention and Follow-Up
✔ Educate patients about avoiding lip-biting or cheek-chewing habits.
✔ Routine oral examinations to detect recurrences early.
✔ Clinical photographs and periodic reviews to document lesion evolution.
Conclusion
Although mucoceles are generally benign, their proper management requires a comprehensive understanding of their clinical forms and current treatment strategies.
With a variety of minimally invasive options now supported by scientific evidence, clinicians have more tools than ever to offer effective and patient-centered care.
Combining education, early diagnosis, and targeted treatment is the key to preventing recurrence and improving quality of life for affected individuals.
