Most mucoceles are left alone if they are small and do not cause issues with speech, eating or aesthetics.
Mucoceles are caused by salivary accumulation within the salivary duct of minor salivary glands when trauma occurs (for example, when the cheek or lip is bitten).
Surgical removal (under local anaesthetic) and biopsy of the mucocele is recommended since that will prevent recurrence and allows confirmation of the diagnosis. Other mucosal lesions (other cysts or tumours) may look very similar to mucoceles and require timely diagnosis and management.
