Genetic defect of lip pit was found to be due to micro deletion on chromosome bands Iq32-q4 (5,6). More recently a mutation in the IRF6gene was identified (7). The main clinical manifestations are pits and/or sinuses of the lower lip associated with cleft lip and /or palate and occasionally hypodontia (8).
What is a lip pit?
A congenital lip pit or lip sinus is a congenital disorder characterized by the presence of pits and possibly associated fistulas in the lips. They are often hereditary, and may occur alone or in association with cleft lip and palate, termed Van der Woude syndrome.
Are lip pits normal?
Lip pits are malformations of lips, often following hereditary pattern, possibly a dominant characteristic and may be associated with other congenital defects. [1] Lip pits can be of three types according to their location: commissural, median upper and median lower. Median lower lip pits are the most common among all.
What is a lip fistula?
Clinically, congenital lip fistulas occur in the vermilion border of the lip, with or without discharge. They are usually bilateral, but may be unilateral or localized centrally on the lower lip [9].

Is cleft palate associated with Down syndrome?
Esophageal, anal and small bowel atresia, preaxial polydactyly, and omphalocele all showed risk increases between 10 and 30 times. Statistically significantly elevated risk ratios around 3-5 were seen for cleft palate, cleft lip/palate, and limb deficiencies.
What causes Van der Woude syndrome?
Cause. Van der Woude syndrome is caused by a variety of mutations in the IRF6 gene on chromosome 1. This gene is involved in the formation of the roof of the mouth and other structures during development.
What causes cheilitis Glandularis?
Cheilitis glandularis is an uncommon condition in the United States. However, factitial injury to the lower lip vermilion border and mucosa due to chronic lip biting, lip drying, or habitual lip licking, combined with sun-induced lip damage, are extremely commonplace.
What is the vermilion zone?
The vermilion border (sometimes spelled vermillion border), also called margin or zone, is the normally sharp demarcation between the lip and the adjacent normal skin. It represents the change in the epidermis from highly keratinized external skin to less keratinized internal skin.
What syndrome is associated with cleft?
Cleft and other associated conditions (syndromes) Sometimes when a child is born with a cleft lip and/or palate there is a chance that they may have additional medical condition/s. These associated conditions include ‘Pierre Robin Sequence’ (PRS), Stickler Syndrome and 22q11 Deletion Syndrome.
What is the ridge between your nose and mouth called?
The philtrum is the vertical groove between the nose and upper lip. The Rank 1 picture portrays a deeply grooved philtrum and very thick upper lip. As you advance up the Guide from Rank #1 to #5, the upper lip becomes thinner and the philtrum becomes smoother.
What is a sinus tract?
A sinus tract is an abnormal channel that originates or ends in one opening. An orofacial fistula is a pathologic communication between the cutaneous surface of the face and the oral cavity. In the literature, the terms fistulas and sinuses are often used interchangeably.

Is cleft lip due to inbreeding?
Cleft lip and cleft palate are thought to be caused by a combination of genes and other factors, such as things the mother comes in contact with in her environment, or what the mother eats or drinks, or certain medications she uses during pregnancy.
What foods cause cleft lip?
NEW YORK (Reuters Health) – Pregnant women who eat a meat-rich, fruit-poor diet may be doubling their baby’s likelihood of being born with a cleft lip or cleft palate, Dutch researchers report.
Why is it called a harelip?
Finally, there’s a “harelip.” This is a congenital condition where the two sides of a person’s upper lip did not fully fuse in the womb, leaving a visible cleft. It’s called a “harelip” because it resembles the upper lip of a hare, which has a cleft between the top lip and the bunny’s nose.
