Why is there a swelling in my child’s inner lip?
A swelling in a child’s inner lip or mouth is commonly a mucocele. Other causes include malformation, dermoid cyst or rarely, tumor. It is important to note the onset, frequency, duration of the swelling and symptoms such as pain or bleeding to aid the diagnosis. The swelling should be evaluated by a paediatric surgeon or pediatric dentist.
What is a mucocele?
A mucocele or mucous cyst is a collection of mucous due to trauma or obstruction to the minor salivary duct. This may be due to habitual biting of the lip or misaligned teeth causing trauma to the mucous membrane. It may involve the floor of the mouth, with resultant extension into the neck, called a “Plunging Ranula.”
When should a mucocele be excised?
As the swelling grows bigger, it may ulcerate, causing pain and bleeding. When symptoms persist, treatment options are, excision, marsupialization or repeated steroid injections. I prefer excision to completely remove the involved minor salivary gland and duct(s). This prevents recurrence of the mucous cyst.
