What kind of doctor treats Maxillary Double Lip?
A primary care doctor is often the first person to see and can examine the lip and confirm what it is. For surgery, they will refer you to a specialist, such as an oral and maxillofacial surgeon or a plastic surgeon.
What it is
A maxillary double lip is a rare condition where a person has an extra fold of tissue on the upper lip. The word maxillary refers to the upper jaw area. The fold sits above the normal lip and may only be visible when the person smiles.
Symptoms
Many people with a double lip have no symptoms. The main sign is a roll or fold of tissue on the inside of the upper lip, which shows more when smiling. Some notice the fold catches on their teeth, and others feel self-conscious about how their lip looks.
Causes and who gets it
Doctors do not always know why a double lip forms. Some people are born with it, while others develop it later after an injury to the mouth or as part of a reaction in the body. In some cases it runs in families.
How doctors diagnose it
A doctor can usually diagnose a double lip just by looking at the mouth. They will ask you to relax your lip and then to smile, since the fold often shows only when you smile. To rule out other growths, they might order an ultrasound.
Treatment
Treatment is not needed unless the fold bothers the person. If treatment is wanted, a surgeon can remove the extra tissue in a short operation, usually done with numbing medicine or medicine that puts the person to sleep. Recovery is often quick, with some swelling for a few days.
When to see a doctor
See a doctor if you notice a new fold or lump on your lip, or if an existing fold changes in size or shape. Also see one if the fold makes it hard to eat, speak, or keep your mouth clean.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid with a flat monthly fee instead of insurance billing. A concierge doctor works similarly but usually charges more and often works alongside your insurance. Either type can examine a double lip, explain what it is, and refer you to the right specialist if surgery is needed.
Common questions
Is a double lip dangerous?
No, a double lip is not dangerous. It is a harmless fold of tissue. The main reasons people treat it are comfort and appearance.
Can a double lip go away on its own?
A double lip that is present from birth usually does not go away on its own. One that appears after swelling may shrink once the swelling goes down. A doctor can tell you which situation you likely have.
Does surgery leave a scar?
Surgeons usually make the cut on the inside of the lip, so any scar is hidden. Swelling and soreness are common for a short time after surgery. Your surgeon will explain the details for your case.
Is a double lip the same as a cleft lip?
No, they are different conditions. A cleft lip is a split in the lip that forms before birth. A double lip is an extra fold of tissue on an otherwise normal lip.
