"The nasal ala projection length demonstrated an average ratio of 93.0 percent in the surgery-alone group and 96.5 percent in the nasoalveolar molding group," this study concluded. A systematic review found in conclusion that nasoalveolar molding had a positive effect on the primary surgery of cleft lip/or palate treatment and aesthetics. [65]
Cleft lip and palate is one of the most common occurring multi-factorial congenital disorder occurring in 1 in 500–1000 live births in several forms. [ 8 ] [ 9 ] [ 10 ] The most common form is combined cleft lip and palate and it accounts for approximately 50% of cases, whereas isolated cleft lip concerns 20% of the patients.
Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
Cleft lip with or without a cleft palate: Alcohol is known to be a folic acid antagonist, and a baby's palate and lip develop during the first trimester of the pregnancy (first 12 weeks). Heavy alcohol consumption and binge drinking during this time have been linked to orofacial cleft.
Cleft lip may be surgically corrected. Generally surgeons repair the lip when the child is still an infant. A second surgery is sometimes necessary for cosmetic purposes when the child is older. Cleft palate may be repaired by surgery or covered by an artificial device (prosthesis) that closes or blocks the opening.
The incisive foramen can be used as a landmark when describing cleft lip and cleft palate, which can either extend in front of (primary) or behind (secondary) the foramen. [6] [7] It is also important as a surgical landmark to avoid damaging its nerves and vascular structures. [3]
Veau-III cleft palate: A cleft of the velum (soft palate), extending unilaterally through the secondary hard palate, past the incisive foramen, and through the primary hard palate and alveolus. The vomer (the bony part of the nasal septum) remains attached to the palatal shelf on the greater segment (non-cleft side).
An example of a birth defect is cleft palate, which occurs during the fourth through seventh weeks of gestation. [14] Body tissue and special cells from each side of the head grow toward the center of the face. They join to make the face. [14] A cleft means a split or separation; the "roof" of the mouth is called the palate. [15]
