What is a unilateral cleft?
A unilateral cleft lip is a common birth defect in which a baby’s lip doesn’t form properly, resulting in a split (cleft) on one side of the lip.
Is cleft palate unilateral or bilateral?
An incomplete palate involves only the back part of the palate. A cleft palate can also be unilateral or bilateral. Unilateral means the palate has a cleft on one side. Bilateral means there is a cleft on both sides of the palate.
What is unilateral incomplete cleft lip?
Unilateral Incomplete Cleft Lip A unilateral cleft lip has clefting of the lip on one side only. There is a normal philtral column, Cupid’s bow and philtral dimple on the side without a cleft. What makes it different from a complete cleft lip is that some orbicularis muscle fibers may cross the cleft.
What is the most common Tessier cleft?
Among the Tessier craniofacial clefts, the number 3 cleft, first reported in 1887 [4], is the most common type. The number 3 cleft passes the philtral column and extends into the lower eyelid medial to the inferior punctum.
What causes unilateral cleft lip?
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.
How is unilateral cleft lip formed?
A unilateral cleft lip occurs when there is failure of complete fusion between the advancing maxillary prominence and the fused medial nasal prominences on one side.
What are facial clefts?
Rare craniofacial clefts are severe deformities of the face and head that affect both bones and soft tissues. Clefts are formed in utero when normal development of a baby’s head and neck are disrupted and parts of the face fail to fuse together, creating facial and/or cranial differences.
What are midline clefts?
Introduction. Midline facial clefts are uncommon facial deformities, the genetics of which are unknown. A median or midline cleft lip has been broadly defined as any congenital vertical cleft through the centre of the upper lip [1]. It was first described by Bechard in 1823.
What country has the most cleft palate?
Data was captured from 55 countries. According to most recent data, the highest total rates of CLP were reported in Venezuela (38 cases/10,000 births), Iran (36 cases/10,000 births) and Japan (30 cases/10,000 births).
What is Logan bow?
The Logan Bow is an external device comprising a curved bow-shaped metal bar, with spikes attached to its cross bars, and is widely used as part of a cleft lip management to maintain postoperative apposition and to avoid excessive strain after cheiloplasty for a cleft lip.
What is the difference between Pierre Robin Syndrome and sequence?
Pierre Robin sequence is also known as Pierre Robin syndrome or Pierre Robin malformation. It is a rare congenital birth defect characterized by an underdeveloped jaw, backward displacement of the tongue and upper airway obstruction. Cleft palate is also commonly present in children with Pierre Robin sequence.
How is the unilateral cleft of the lip corrected?
The distorted anatomy of the unilateral cleft of the lip is corrected by a rotation incision that releases lip tissue, including the Cupid’s bow, downward into normal symmetric position with the opposite side and advances the lateral lip element into the rotation gap to maintain rotation and complete the lip reconstruction.
Is there a unilateral cleft palate in Dallas?
Unilateral Cleft Lip/Palate in Dallas, TX. A unilateral cleft lip/palate affects only one side of the mouth and may be present in varying degrees. An accurate diagnosis followed by expert care from the highly skilled physicians of the International Craniofacial Institute can dramatically affect a child’s quality of life.
How does the Mohler back cut work for cleft lip?
The cleft side lip shortening will be lengthened in this technique by 1) the Mohler columellar back cut, 2) the curvilinear Rose-Thompson effect, and 3) the cutaneous back cut. The Mohler back cut is designed as an equilateral triangle (approximately 2mm on each side) on the columella and provides 1-2mm of lip and columellar lengthening.
When was the first cleft lip repair performed?
However, because of the limitations of this article, the authors choose to focus on the repair Millard first described in 1955, as today it is perhaps the most commonly adapted repair of cleft lip.
