Bilateral and Unilateral Cleft Lip: Slots Diagnosis
The cleft lips have the same prevalence in the general population as trisomy 21 is about 1 / 700, this frequency varies by race: 3.6 / 1000 among American Indians against 0.3 / 1,000 among blacks.
The cleft lip and palate and maxillofacial bilateral clefts are more common in boys than in girls. There is a bilateral cleft slots for 4 unilateral, when isolated. The cleft lip associated with cleft palate in 70% of unilateral clefts and 85% of bilateral clefts.
These are not exceptional anomalies associated with malformation in a context less than 10% of cases of cleft lip, this rate increases if the slot is bilateral, it is 15 to 50% if the palate is cleft. These malformations are most often isolated, rarely inherited.
Outside the contexts malformation, prenatal diagnosis of major interest to the slot to prepare parents and carers at home and the child’s disability.
Positive cleft lip diagnosis
Unilateral cleft lip alone
The lip: break Cupid’s bow, the slot is lateralized, usually closely related to the still lower edge of the lip, nostril up to the threshold that may be involved. The nose is more or less deformed, the nostril is slightly flattened on the side of the slot, the partition is slightly deflected. If the threshold is not affected nostril, one can note a decrease in the thickness of soft tissue on the side of the slot.
The maxillary dental alveoli are tidy, the cavity of the lateral incisor on the side of the slot may be a little set back.
Alveolar cleft lip, unilateral.
Lip: the slot is wider, with a thick rim median, under the nose prominent sagittal section.
The nose is definitely bent, the nostril on the side of the slot is enlarged and flattened, the tip is deflected toward the slot, and the wall is oblique. The maxilla: the alveolar cleft between the groups, with opening of the maxillary arch side of the slot.
Cleft lip and palate maxillary unilateral.
Lip: the slot is wide.
The nose is deformed. The maxillary bone slot is even clearer that the amniotic fluid passes the nasal cavity in the mouth, noting the defect at a mouth opening and if the slot is wide, the tongue gets into the nasal cavity during swallowing movements. Cleft palate can be objectified on a cutting plane axial oblique.
Only the bony cleft palate can be visualized by ultrasound.
Symmetric bilateral cleft lip
Lip: the slots are symmetrical with respect to the nostrils, with a median bud is not bone, prominent in the nose, the septum is in short, the nose is small, flattened, the partition is not deflected, the nostrils are small.
The maxilla: no disturbance in the tooth sockets
Alveolar cleft lip and bilateral and symmetrical
Lip: the slots are wider, the median process is very prominent, sometimes exceeding the tip of the nose, it has a component containing the bone cells of the central incisor germs.
The nose is flat, the nostrils are difficult to distinguish, in deck stretched forward slots.
The maxillary bone defect is the median, broad, since the cells of the central incisors are in the median labial bud.
Cleft lip and palate maxillary bilateral and symmetrical
Lip and nose abnormalities are identical, the deviated septum is not perfectly visible and because its lower edge is in contact with the tongue when the mouth is closed, it is emphasized by the amniotic fluid in the mouth opening.
Asymmetric bilateral cleft
It can be isolated from a labial side and lip-jaw-palate of the other. It looks like a unilateral cleft, only the careful study of the lip can see cleft lip contralateral.
Corresponds to agenesis of the premaxilla
There is one opening the mouth and nose, 4 shoots lip and nasal primitive form the edges of the single cavity. On a sagittal median, there’s no relief no nasal nasal bone.
Isolated cleft palate
The ultrasound is more often faulted.
The only sign of Appeal may be a discrete retrognathia sometimes a simple shift of the lower lip on a sagittal section plane. The study of tongue position during swallowing movements shows a high position and back of the tongue.
Contribution of 3D ultrasound
Surfacing technique provides a better limit the height of the slot relative to the threshold nostril. The study of the block volume is an undeniable contribution in cleft palate, to objectify them and appreciate their importance and depth.
Slots and malformation syndrome
The association is not unique, a thorough review is needed. Into cracks or bilateral median, the association with brain abnormalities is common; they are anomalies of the midline: holoprosencephaly, median cleft for, agenesis of the corpus callosum bilateral. Slots for a systematic search for disease amniotic bands, imposes a fine and meticulous study of the ends, in this case the slots are often large and decaying with a loss of substance complicating considerably the possibilities for surgical repair.
The associations are the most common malformations:
Heart in 3-7% of cases
Esophageal atresia: 5%
Cervical vertebral anomalies: 13%
Small size is 4 times more frequent than in the general population
Chromosomal abnormalities: 8%
