Cleft lip and palate (CL/P) is one of the most common congenital craniofacial abnormalities. It is characterized by failure of normal fusion of the palate and lip at the midline during development resulting in a clinically obvious deformity of the newborn Cleft lip and palate are birth defects of the mouth and lip, also known as oral-facial clefts. A normal fetus has a split lip and palate, but early in pregnancy, the sides of the lip and the roof of the mouth should fuse. Failure of fusion results in cleft lip and/or cleft palate Cleft lip and/or palate are the most common congenital facial deformities at birth and result from failure of fusion of the frontal prominence with the maxillary process during embryogenesis. These deformities account for about 10% of all congenital anomalies. Most medial facial clefts account for less than 1% of all facial clefts
Summary. Cleft lip and cleft palate (CLP) are the most common congenital orofacial deformities. A combination of genetic predisposition and in-utero exposure to teratogens (nicotine, alcohol, antiepileptic drugs) can arrest the fusion of the facial processes required for normal facial development.Failure of fusion of the maxillary prominence with the medial nasal prominence causes cleft lip (CL) Cleft lip occurs because of the failure of fusion of the maxillary and medial nasal processes. Cleft palate can affect the hard palate, soft palate, or both the hard and soft palate (see Figure 13-5) Therefore, cleft lip and palate is failure of fusion between the two sides of the lip or palate. The word cleft literally means a split, or a division. The condition can affect either the lip, the palate, or both the lip and the palate. So cleft lip and palate can usually be categorized as Cleft lip and cleft palate occur when tissues in the baby's face and mouth don't fuse properly. Normally, the tissues that make up the lip and palate fuse together in the second and third months of pregnancy. But in babies with cleft lip and cleft palate, the fusion never takes place or occurs only part way, leaving an opening (cleft)
Deformities which prevent midline fusion, such as micrognathia and/or macroglossia, may result in a failure of midline fusion and therefore a secondary cleft palate. [1,2,3] Clefts of the palate and lip are also classified as complete or incomplete. Complete clefts of the lip and alveolus involve extension into the anterior nose Cleft of the secondary palate is due to lack of fusion of the palatal shelves of the maxil- lary processes, which normally takes place at 8-12 weeks of gestation (Fig 3) (2) Cleft Lip and Palate. CSD 2230. INTRODUCTION. Between the 6th and 12th weeks of fetal gestation,the left and right sides of the face and facial skeleton fuse in the midddle. When they do fail to do so, the result is a craniofacial cleft. Various types of clefts may occur as isolated condition or as part of a syndrome
Cleft lip and/or palate is a developmental defect resulting from a failure of the mesial nasal process to fuse with the lateral nasal process and/or the maxillary process. This seemingly simple fusion failure is consequential, leading to significant structural deformities and functional deficits A cleft lip is formed when normal development is interrupted before 7th week of gestation. The degree of clefting can vary• Deformational cleft lip is seen when failure of fusion of the maxillary and median nasal processes occurs manifested in the form of a fissure in the lip 10 When there is normal fusion between the FNP and maxillary prominences creating a normal lip and alveolus, but there is lack of fusion between the lateral palatine processes of the opposing maxillary prominences, an isolated cleft of the secondary palate occurs
Lip cleft can occur as a one-sided (unilateral) or two-sided (bilateral) condition. It is due to the failure of fusion of the maxillary prominence and medial nasal processes (formation of the primary palate) The lip forms between the 4 th and 7 th weeks of pregnancy. The roof of the mouth (palate) is formed between the 6 th and 9 th weeks of pregnancy. The condition results during the 4 th to 6 th weeks of gestation from a failure of fusion of one or both of the medial nasal prominences. These initially occur as paired medial nasal processes and. The mammalian lip and primary palate form when coordinated growth and morphogenesis bring the nasal and maxillary processes into contact, and the epithelia co-mingle, remodel and clear from the fusion site to allow mesenchyme continuity. Although several genes required for fusion have been identifie . occurs more often in males. cleft palate occurs in 1 in 2,000. occurs more often in females. of the known 200 syndromes associated with cleft lip and palate, van der Woude syndrome is the most common. due to mutations on chromosome 1. characterized by facial deformities, most commonly lip pits Cleft lip and palate 1. CLEFT LIP AND PALATE Dr. Saleh Bakry Associate Professor of Oral and Maxillofacial Surgery 2. • Cleft lip and palate is the second most common congenital anamoly after clubfoot • Amoung the 15 types of orofacial clefting, cleft lip and palate is the most common one
lip. Failure of fusion to occur in the human primary palate results in a cleft in the upper lip that extends into the nostril. However, the midline of the upper lip is intact in patients with cleft lip. In contrast, clefts of the secondary palate occur later in development than cleft lip and are because of the failure of fusion of the palatal. The failure of this fusion process produces a cleft lip, which can be either unilateral or bilateral. At about 7 weeks of gestation, a fusion process moves caudally from the incisive foramen through the hard palate and the soft palate to the tip of the uvula. Failure of this fusion process produces a cleft palate Congenital Oronasal Fistulas (Cleft Palate and Cleft Lip): Congenital oronasal fistulas are the result of failure of fusion of the palatine shelves during gestation (which occurs at 25-28 days of gestation in dogs). Clefts can be either of the primary palate (involving the lip and incisive bone) causing cleft lip (harelip), or of the. Conversely, isolated CP results from failure of primary fusion of the palates, which may occur after closure of the lip because palatal fusion occurs 56 days postconception. ETIOLOGY AND EPIDEMIOLOGY The most common craniofacial defect is the cleft lip with or without cleft palate (CL/P) and isolated CP Cleft lip and palate together represent the most common congenital defor-mity1 of the head and the neck. Oral clefts, including cleft lip (excessively wide head), 4) failure to fuse or 5) rupture after fusion of the shelves. 3. Epidemiology of cleft lip and palate Incidences of CL, CLP, and C

Learn vocabulary, terms, and more with flashcards, games, and other study tools. failure of fusion of primary and secondary palate cleft lip is caused by failure of fusion of which processes cleft palate - An abnormality of face development leading to an opening in the palate, the roof of the oral cavity between the mouth and the nose. Clefting of the lip and or palate occurs with 300+ different abnormalities. In most cases clefting of the lip and palate can be repaired by surgery Cleft lip and palate (CLP) is the most common congenital deformity of the orofacial. Clefts are thought to be of multifactorial etiology due to genetic and environmental factors. Different dental abnormalities are usually seen in cleft patients, including midface deficiency, collapsed dental arches, malformation of teeth, hypodontia, and supernumerary teeth Surgery is usually performed at 3 months for cleft lip repair and 6 months for cleft palate. It may be delayed by the investigation of other problems or on-going airway difficulties; in such cases, the timing of surgery is critical and is best decided by discussion between all specialities involved, including anaesthesia
Complete failure of fusion results in a cleft of the lip through the vermilion border that extends to the ipsilateral alar base and a cleft of the ipsilateral alveolar process (ie, primary palate) . The primary palate or premaxilla is a component of the medial nasofrontal process, which ultimately becomes the medial upper lip and alveolus. from cleft lip and palate A/Jaxmice havethe potentiality to fuse at the normal im vivo time of palatal fusion. He postulated that the cleft palate occurred with the cleft lip as the result of either a systemic al-teration of the capability to fuse or as a mechanical consequence of cleft lip. He found that in all cases the palatal shelves fused. . Orofacial clefts are a heterogeneous group of disorders affecting the structure of the face and oral cavity that have been divided into three general categories: those that affect the lip only (CL, Fig 1A), those affecting the lip and palate (CLP, Fig 1B), and those affecting the palate alone (CP, Fig 1C).Historically, CL and CLP have been considered variants of the. A cleft lip is a split, or cleft, in the skin of the upper lip. This defect can range in size from a tiny, almost imperceptible hole to a very large opening that includes the top gum and top jaw. A cleft palate is an opening in the roof of the mouth. This opening can go through the bony hard palate around the top row of teeth; through the.
Cleft lip is a common development defect that affects approximately 1:1000 births, most of which are male. This defect involves a partial or complete failure of the right and left portions of the upper lip to fuse together, leaving a cleft (gap). A more severe developmental defect is cleft palate, which affects the hard palate Complete bilateral cleft palate is due to failure of fusion of the . a) palatine processes. b) palatine and frontonasal processes. c) palatine, frontonasal and secondary nasal processes. d) palatine, frontonasal, secondary nasal processes and mandibular processes. Question 3. The face is formed by the fusion of four outgrowths of mesenchyme (front nasal, mandible and paired maxillary swellings) and facial clefting is caused by failure of fusion of these swellings. Cleft lip with or without cleft palate is usually (more than 80% of cases) an isolated condition, but in 20% of cases it is associated with one of more.

Cleft of the upper lip that extends upward toward the left nostril and left anterior cleft of the primary palate just deep to the cleft lip. These defects are most likely due to a failure of Maxillary process to fuse the medial nasal process. Isolated cleft lip and palate is Multifactorial. Cleft lip, cleft palate, polydactyly, microcephaly. Cleft lip Cleft lip arises early on when a baby is in the womb. It occurs when the components that make up the lip fail to join up properly. This is referred to as a failure of fusion. There are many reasons why cleft lip occurs; sometimes there can be a family history of clefts, sometimes it just happens out of the blue Clefts of the lip and cleft palate are fusion disorders that affect the midfacial skeleton. They are one of the most common congenital anomalies with a worldwide incidence of between 0.8 and 2.7 cases per 1000 live births. The incidence of clefting varies by region, gender, ethnicity and maternal characteristics Midline cleft lip and palate (premaxillary agenesis). Cleft associated with amniotic bands or limb-body wall complex. Pathogenesis: Normally formed palate but incomplete fusion of the lip.

Cleft lip and cleft palate are the most common congenital anomalies of the face and skull, affecting approximately one in.
Cleft palate with or without cleft lip CP ± CL Excludes cleft lip and cleft lip and alveolus Cleft lip and/or cleft palate CL/P No exclusion Modified from Huang AH, Patel KB, Maschhoff CW, et al. Occlusal classification in relation to original cleft width in patients with unilateral cleft lip and palate DEFINITION Cleft Lip (Cheiloschisis): It is defined as a congenital anomaly in which there is presence of a fissure at upper lip which occurs due to failure of fusion of the maxillary and median nasal processes Cleft Palate (Palatoschisis): It is defined as a congenital anomaly in which there is a fissure at roof of the mouth which occurs due. Generally, cleft lip and cleft palate occur as a result of the inability of the tissues of the lip to fuse properly as well as the failure of the tissues of both the hard and soft palate to blend properly. However, what causes this inability is still unknown. Usually, these tissues are meant to fuse properly in the first trimester of pregnancy.
Cleft lip is formed at the top of the lip as either a small gap or the indentation in the lip (partial or incomplete cleft) or it continues into the nose (complete cleft). Lip cleft can be unilateral or bilateral. It is caused by the failure of fusion of the maxillary and medial nasal processes. A mild form of a cleft lip is a microform cleft . Figure 44-2 shows the locations of the globular process and the right and left maxillary processes. with normal fusion, no cleft lip results Cleft lip and cleft palate is a group of conditions that includes cleft lip, cleft palate, and both together.A cleft lip contains an opening in the upper lip that may extend into the nose. It is due to the failure of fusion of the maxillary and medial nasal processes. The opening may be on one side, both sides, or in the middle. These disorders can result in feeding problems, speech problems. In patients with unilateral cleft lip and palate, the prevalence was 22.2%, while in those with bilateral cleft lip and palate, the prevalence was 19.1%, and in patients with cleft palate only, the prevalence of upper cervical vertebrae anomalies was 16.6%. The study involved 128 patients with cleft lip/palate and 125 controls Multiple animal models have been used to study tissue fusion and many types of tissue fusion events occur within a developing organism. Importantly, the inability of tissues to fuse correctly during development can lead to various birth defects, including cleft palate (Abbott, 2010), spina bifida (Copp et al., 1990) and heart defects (Wenink and Zevallos, 1988)
Cleft lip, with or without cleft palate, occurs more frequently than cleft palate alone and is the most common of the significant orofacial anomalies. 7 Clefts of the lip and anterior maxilla have been thought to result from a deficiency of mesenchyme in the facial region due to failure of either migration of the neural crest cells or. Cleft lip and cleft palate, which can also occur together as cleft lip and palate are variations of a type of clefting congenital deformity caused by abnormal facial development during gestation.This type of deformity is sometimes referred to as a cleft.A cleft is a sub-division in the body's natural structure, regularly formed before birth. A cleft lip or palate can be successfully treated. Cleft of lip and palate (CLP) originates from failure in the fusion of oronasal processes within the first five to six weeks of gestation.1,2 Clefts are classified as complete or incomplete, bilateral or unilateral and syndromic or non-syndromic.2,3 Among the aetiological factors identified Cleft lip (cheiloschisis) is a congenital anomaly that occurs at a rate of 1 in 800 births. It is formed in the top of the lip as either a small gap or an indentation in the lip or it continues into the nose (complete cleft) it is due to the failure of fusion of the maxillary and medial nasal processes. Children with these structural disorders may have associated dental malformations, speech. The overall occurrence of cleft lip with or without cleft palate is approximately 1 in 750-1000 live births. Racial differences exist, with the incidence in Asians (1:500) greater than in Caucasians (1:750) greater than in African Americans (1:2000). The incidence of cleft lip/palate is more common in males
Cleft lip and cleft palate is cause due to improper fusion of the facial tissues in the middle. It affects one in 700 babies. There may be just a cleft in the upper lip or the cleft may affect the. cleft lip (cleft palate) congenital fissure, or split, of the lip (cleft lip) or of the roof of the mouth (cleft palate); one or the other occurs in about one birth per thousand.Sometimes they are associated with clubfoot (talipes) or other anatomic defects. They have no connection with mental retardation. Although poor health of the mother during pregnancy may have some effect on the.
Cleft palate and cleft lip result from failure of the two sides of the face to unite properly at an early stage of prenatal development. The defect may be limited to the outer flesh of the upper lip (the term harelip, suggesting the lip of a rabbit, is both inaccurate and unkind), or it may extend back through the midline of the upper jaw. Cleft lip: A fissure in the upper lip that is due to failure of the left and right sides of the fetal lip tissue to fuse, an event that should take place by 35 days of fetal age. Cleft lip can be on one side only or on both sides. Because failure of lip fusion can impair the subsequent closure of the palatal shelves, cleft lip often occurs in association with cleft palate Isolated cleft palate (CPO) is the rarest form of oral clefting. The incidence of CPO varies substantially by geography from 1.3 to 25.3 per 10,000 live births, with the highest rates in British Columbia, Canada and the lowest rates in Nigeria, Africa. Stratified by ethnicity/race, the highest rates of CPO are observed in non-Hispanic Whites and the lowest in Africans; nevertheless, rates of.
left lip and palate (CLP) is a frequently encountered congenital anomaly occurring due to a failure fusion of maxillofacial processes in the embryonic period. Clefts can be classified as syndromic (combined with other malformations) and non-syndromic (isolated) cleft lip and palate. There ar Ocular coloboma is an excavation of ocular structures that occurs due to abnormal fusion of the embryonic optic fissure. Further, cleft lip/palate (CL/P), a congenital midline abnormality, is caused by a defect in the fusion of the frontonasal, maxillary, and mandibular prominences. No study has reported the association between these two phenotypes in the absence of other systemic abnormalities Premature fusion of several sutures causes a short wide head. The upper jaw is underdeveloped. Clefts Lip and Palate. A cleft of the lip and palate can be complete or incomplete. In an isolated cleft palate, which involves only the palate, little aesthetic deformity may be present Question 13 Lack of fusion of these bones may cause cleft palate/cleft lip: O a) palatine O b) ethmoid O c) maxillary O d) sphenoid O e) both a and c Question 14 Paranasal sinuses: O a) serve as resonating chambers for speech O b) lighten the weight of the skull O c) are located in the occipital, frontal, and temporal bones O d) both a and b O e) all of the abov Cleft upper lip, superior alveolar arch and palate -- It results from failure of fusi It results from failure of fusion of medial nasal and maxillary prominences They could be unilateral or bilateral Bilateral Oblique Cleft of the Face. 9/15/2010 1
Failure of fusion between any of the facial structures (eg, failure of maxillary swellings to fuse with the intermaxillary process leading to cleft; see discussion above) results in a cleft, which may be unilateral or bilateral Cleft Lip: A congenital facial defect of the lip due to failure of fusion of the medial and lateral nasal prominences and maxillary prominence. (American Cleft Palate-Craniofacial Association) Cleft Palate: A congenital fissure in the medial line of the palate. (American Cleft PalateCraniofacial Association)- Related Medical Polic
A cleft lip is an opening of the upper lip mainly due to the failure of fusion of the medial nasal processes with the palatal processes, a cleft palate is the opening of the soft and hard palate in the mouth which is due to the failure of the palatal shelves to fuse together The lips and palate originate from three areas of the baby's developing face: Left and Right Maxillary Prominences: grow and become the lower face, lower lip and jaw, all but the middle portion of upper lip and jaw, and the secondary palate (behind the four upper middle teeth to back of mouth. These three prominences on the child's. Cleft palate results from a failure of fusion of the palatal shelves. Isolated cleft palate (without cleft lip) is in the back of the palate. It can involve the hard and soft palate or just the soft palate. Children with cleft palate typically have underdevelopment of the mid-face (flat midface) and often a small chin Cleft Palate or Lip in Puppies and Kittens.

About 1 in every 2,800 babies is born with cleft lip without cleft palate in the United States. About 1 in every 1,700 babies is born with cleft palate in the United States. 1; Causes and Risk Factors. The causes of orofacial clefts among most infants are unknown. Some children have a cleft lip or cleft palate because of changes in their genes A cleft is a birth defect that occurs when the tissues of the lip and/or palate of a fetus do not properly fuse very early in the pregnancy. A cleft lip,sometimes referred to as a harelip, is an elongated opening between the upperlip and the nose. It may involve one or both sides of the lip and may occurwith or without a cleft palate Ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) syndrome is a form of ectodermal dysplasia, a group of about 150 conditions characterized by abnormal development of ectodermal tissues including the skin, hair, nails, teeth, and sweat glands.Among the most common features of AEC syndrome are missing patches of skin (erosions). In affected infants, skin erosions most commonly occur on. Nursing Assessment A Failure of fusion of the lip palate or both B Difficulty from SPC 1017 at Palm Beach State Colleg Cleft lip and cleft palate is basically a failure of fusion, but not a missing body part. They are among the most common birth defects affecting children in North America. The cleft can affect one or both sides of the face and can vary in severity
Cleft lip is an opening in the upper lip due to incomplete formation of the upper lip before birth. It may be unilateral or bilateral (on both sides of lip). Cleft palate is an opening of the hard palate or soft palate (roof of the mouth) due to its incomplete fusion. It may also be unilateral or bilateral Individuals with isolated cleft lip and/or palate (ICLP) are often reported to be of shorter stature relative to peers, and the objective of this study was to explore the role of the pituitary in. Cleft lip (CL) referred to as harelip[1, 2] and cleft palate (CP) are variations of a congenital deformity caused by abnormal facial development during intra-uterine life. The oro-facial clefts may be complete or incomplete, unilateral or bilateral, primary or secondary depending on the degree of failure of fusion of palatal shelves [1, 3].CL and CP are the most common major congenital. Cleft palate. Cleft palate is a common congenital malformation of the palate. It results from the partial or complete failure of fusion of the palatine processes of the maxillae and/or the horizontal plates of the palatine bones during embryonic development A cleft lip or palate is a congenital anomaly in which a gap develops in either the upper lip or the roof of the mouth. The condition occurs when bones in the skull do not correctly fuse together.
Cleft lip and palate are openings or splits in the upper lip or roof of the mouth (palate). A child can be born with a cleft lip, cleft palate, or both. Cleft lip and palate may be the only birth defects, or they may happen with other defects. A cleft lip may be as mild as a notch of the lip. Or it may be as severe as a large opening from the. hare lip (bilateral failure of maxillary and medial nasal prominences to fuse) Disruption of growth of the tongue and/or mandible can therefore secondarily cause a cleft secondary palate. Complete fusion of the primary and secondary palate is a complex process involving growth of the component tissues, epithelial to mesenchymal. Cleft Lip. A cleft lip can range from a little notch in the coloured part of the lip to a complete separation of the upper lip which can extend up and into the nose. This can affect one side of the mouth (unilateral) or both sides (bilateral), and can be complete (meaning the cleft goes up into the nose) or incomplete
