6 bundles · 11 layers · 16 findings · 26 questions
Lesion identity and mechanism Establish what the mucocele label means for this lesion and which anatomical process it represents.
Extravasation and retention
Separate the diagnostic label from evidence about mucus leakage or ductal retention.
Mechanism evidence
Record the mechanism as a supported interpretation, retaining indeterminate status when the available evidence cannot distinguish it.
- Does the clinician use oral mucocele for extravasation alone or for both extravasation and retention? definition
- Which examination or pathology report supports the assigned mechanism? provenance
Gland origin and ranula boundary
Locate the lesion relative to minor salivary glands, the floor of mouth and any cervical component.
Anatomical classification
Represent suspected gland origin separately from surface location and link a narrower ranula model when appropriate.
- What evidence identifies the associated gland or duct rather than merely the visible swelling site? provenance
- Does floor-of-mouth or neck involvement require classification as oral or plunging ranula and linkage to another model? boundary
Oral phenotype and course Describe the visible lesion and its behaviour across observations.
Site and morphology
Capture reproducible oral examination findings.
Dated lesion profile
Combine precise location, dimensions and examination findings with the method and observer.
- What are the exact oral site, laterality, number of lesions and dimensions in millimetres? measurement
- Which colour, surface, consistency and tenderness findings were examined directly, and which came from a photograph or patient report? provenance
Rupture, refilling and persistence
Track the sequence of swelling, collapse and reappearance.
Lesion episode continuity
Preserve enough chronology to distinguish persistent swelling, refilling of the same lesion and a separate lesion.
- When was the swelling first noticed, and when did rupture, collapse or refilling occur? measurement
- What evidence establishes that a later swelling occupies the same site and belongs to the same episode? boundary
Causal context and diagnostic confidence Connect local exposures and diagnostic evidence without turning plausible explanations into established facts.
Local trauma and obstruction
Assess temporal and anatomical links to possible duct injury or obstruction.
Precipitant assessment
Record the proposed precipitant, its timing and whether it remains present.
- Did biting, an appliance, a sharp tooth, injury or an oral procedure precede swelling at this site? provenance
- What supports duct obstruction or continuing irritation, and what clinician-directed action could address it? action
Mimics and confirmation
Make alternative diagnoses and unresolved contradictions explicit.
Diagnostic evidence gap
Record why the working diagnosis remains credible and what further evidence would change it.
- Which findings leave a vascular lesion, fibroma, infection or salivary neoplasm unresolved? boundary
- What clinical question would specialist examination, imaging or histopathology answer before treatment is selected? action
Symptom burden and care decision Relate oral function and diagnostic confidence to a documented care plan.
Oral function and assessment priority
Record interference with daily oral activities and symptoms that alter urgency.
Functional impact assessment
Swallowing or breathing interference can require prompt assessment, particularly with floor-of-mouth lesions. [Mucocele and Ranula](https://www.ncbi.nlm.nih.gov/books/NBK560855/)
- Does the lesion interfere with eating, speech, swallowing or breathing, and how has this changed? measurement
- Do the current symptoms require urgent assessment rather than the existing follow-up plan? action
Observation or intervention
Capture the clinician's chosen approach and reasons.
Management rationale
Spontaneous resolution is possible; persistent, recurrent or symptomatic lesions may warrant treatment. Record the individual decision and review plan. [Mucocele and Ranula](https://www.ncbi.nlm.nih.gov/books/NBK560855/)
- What supports observation, referral or a specific intervention for this lesion? action
- What review date and changes in swelling, symptoms or appearance should trigger reassessment? action
Treatment result and recurrence Connect any intervention to diagnostic results, healing and subsequent swelling.
Intervention and pathology
Preserve what was treated and what tissue examination established.
Procedure-diagnosis reconciliation
Link the procedure record and any specimen report to the original lesion, revising the diagnosis when necessary.
- What procedure was performed, at which site, and was associated gland tissue treated or sampled? provenance
- If tissue was examined, did the report confirm a mucocele, establish its mechanism or identify another diagnosis? boundary
Healing and return of swelling
Assess sustained disappearance, functional recovery and possible recurrence.
Verified follow-up state
Record the latest verified outcome and elapsed observation time without assuming that absence of follow-up means cure.
- How long has the site remained free of swelling, and are pain, altered sensation, scarring or functional problems present? measurement

What it is Filled
An oral mucocele is a localized accumulation of salivary mucus in the oral soft tissues, usually caused by leakage from a damaged minor salivary gland duct and less often by mucus retention within an obstructed duct.
In scope
- Individual oral lesions suspected or confirmed to be mucoceles
- Salivary mucus extravasation versus ductal retention, including unknown mechanism
- Oral site, appearance, dimensions, symptoms and rupture-refilling history
- Diagnostic evidence, competing explanations and reasons for specialist assessment
- Clinician-selected management, resolution, recurrence and treatment complications
- Identification of a possible ranula and linkage to a more specific model if one exists
Out of scope
- General salivary gland anatomy and physiology
- Independent models of salivary stones, duct obstruction or systemic salivary disease
- Full models of vascular lesions, abscesses and salivary neoplasms
- Detailed operative protocols and procedural competency requirements
- Extraoral mucoceles, including paranasal sinus and appendiceal mucoceles
- Detailed management of plunging ranula and cervical extension
Why it exists Filled
Enable an AI agent to recognise a suspected oral mucocele, record diagnostic uncertainty and lesion evolution, and support clinician-directed assessment, management and follow-up.
Distinguishing features Filled
- A fluctuant, translucent or bluish lower-lip swelling supports mucocele recognition; site and appearance alone do not establish the diagnosis. [AAPD oral pathology guidance](https://www.aapd.org/globalassets/media/policies_guidelines/bp_oralpathology.pdf)
- On histology, extravasation involves mucus outside the duct without an epithelial cyst lining, whereas retention involves an epithelial-lined dilated duct; record the reported tissue evidence rather than inferring subtype from appearance. [Clinical and histopathological study](https://pmc.ncbi.nlm.nih.gov/articles/PMC4211243/)
- A floor-of-mouth lesion with major salivary gland involvement raises the ranula classification; neck extension requires a further boundary assessment. [Mucocele and Ranula](https://www.ncbi.nlm.nih.gov/books/NBK560855/)
- A mucocele-like lesion at an atypical site requires consideration of a salivary neoplasm; a benign-looking surface cannot settle that distinction. [AAPD clinical discussion](https://www.aapd.org/globalassets/media/publications/archives/flaitz-22-04.pdf)

Recognition optional Filled
- A superficial lesion may appear as a smooth, rounded swelling with a translucent or bluish surface.
- Deeper lesions may retain the normal color of the surrounding oral mucosa.
- The inner lower lip is a common location, but appearance and location alone cannot establish the diagnosis.
Capabilities and actions required Filled
- Assemble a dated lesion profile for dental or oral medicine assessment.
- Compare serial measurements and photographs to identify collapse, refilling or sustained disappearance.
- Flag missing evidence or conflicting findings before treating a suspected mucocele as confirmed.
- Link possible trauma or duct obstruction to the lesion while preserving causal uncertainty.
- Support clinician selection and documentation of observation, investigation, referral or treatment.
- Track pathology results, recurrence and adverse effects against the original lesion episode.
Hazards and failure modes required Filled
- Mistaking another oral lesion for a mucocele can delay appropriate assessment.
- Repeated trauma or attempted self-treatment can cause bleeding, infection or further tissue injury.
- Persistent or recurrent swelling can interfere with eating, speech or comfort.
Standards and interfaces required Filled
- ICD-10 category K11.6, issued by the World Health Organization, classifies mucoceles of salivary glands.
Context of use required Filled
- An oral mucocele is encountered during dental or medical assessment of a localized swelling inside the mouth.
- Recording its location, duration and changes helps clinicians assess a suspected salivary lesion and distinguish it from other causes of oral swelling.

Open questions
- Does an existing Vercy world model already own oral mucocele, and does the registry separately represent ranula or salivary duct retention cyst?
- Should the registered term include both extravasation and retention lesions, and how should differing clinical and pathological terminology be reconciled?
- Is the supplied ACT / ACT.ACT placement intentional for this condition, or does registry governance require a classification review?
- Which evidence-supported persistence, atypical-site and examination criteria should trigger biopsy or specialist referral for each age group?
- What comparative evidence supports treatment selection and the follow-up duration needed to assess recurrence across lesion sites, sizes and mechanisms?
