Cleft Lip & Palate
A cleft lip is a separation of the upper lip into two sides. This can include the bone of the upper jaw and is then called cleft palate.
During early pregnancy, separate areas of the face develop individually and then join together, including the left and right sides of the roof of the mouth and lips. However, if some parts do not join properly, sections don’t meet and the result is a cleft. If the separation occurs in the upper lip, the child is said to have a cleft lip.
A cleft may vary in its extent to include some or all of the lip and palate. A cleft on one side is called a unilateral cleft. If a cleft occurs on both sides, it is called a bilateral cleft. A completely formed lip is important not only for a normal facial appearance but also for sucking and forming certain sounds made during speech. A cleft lip is a condition that creates an opening in the upper lip between the mouth and nose. This may range from a small notch in the gum to a complete division of the gum into separate parts. A similar defect in the roof of the mouth is called a cleft palate.
The palate has an extremely important role during speech because when you talk, it prevents air from blowing out of your nose instead of your mouth. The palate is also very important when eating. It prevents food and liquids from going up into the nose.
Cleft lip surgery is usually performed when the child is about 10 weeks old. The goal of surgery is to close the separation, restore muscle function and provide a normal shape to the mouth. The nostril deformity may be improved as a result of the procedure or may require subsequent surgery.
A cleft palate is initially treated with surgery safely when the child is between 7 to 18 months old. This depends upon the individual child and his/her own situation. For example, if the child has other associated health problems, it is likely that the surgery will be delayed.
The major goals of surgery are to:
- Close the gap or hole between the roof of the mouth and the nose.
- Reconnect the muscles that make the palate work.
- Make the repaired palate long enough so that the palate can perform its function properly.
There are many different techniques that surgeons will use to accomplish these goals. The choice of techniques may vary between surgeons and should be discussed between the parents and the surgeon prior to the surgery.
The cleft hard palate is generally repaired between the ages of 8 and 12 when the cuspid teeth begin to develop. The procedure involves the placement of bone from the hip into the bony defect, and the closure of the communication from the nose to the gum tissue in three layers. It may also be performed in teenagers and adults as an individual procedure or combined with corrective jaw surgery.
After the palate has been fixed, children will immediately have an easier time swallowing food and liquids. However, in about 1 out of every 5 children following cleft palate repair, a portion of the repair will split, causing a new hole to form between the nose and mouth. If small, this hole may result in only an occasional minor leakage of fluids into the nose. If large, however, it can cause significant eating problems, and most importantly, can even affect how the child speaks. This hole is referred to as a “fistula,” and may need further surgery to correct.
Children born with these conditions usually need the skills of several professionals to manage the problems associated with the defect such as feeding, speech, hearing, and psychological development. In most cases, surgery is recommended. When surgery is done by an experienced, qualified oral and maxillofacial surgeon such as Dr. Williams, the results can be quite positive.
