Definition

Oblique facial clefts are a rare form of orofacial clefting, comprising about 0.25% of all facial clefts. Two major types have been described classically: nasoocular and oroocular, the latter of which can be subdivided into oromedial-canthal and orolateral-canthal (summary by Dasouki et al., 1988). [from OMIM]

Clinical features

From HPO
Talipes calcaneovalgus
MedGen UID:
56270
Concept ID:
C0152237
Anatomical Abnormality
Talipes calcaneovalgus is a flexible foot deformity (as opposed to a rigid congenital vertical talus foot deformity) that can either present as a positional or structural foot deformity depending on severity and/or causality. The axis of calcaneovalgus deformity is in the tibiotalar joint, where the foot is positioned in extreme hyperextension. On inspection, the foot has an "up and out" appearance, with the dorsal forefoot practically touching the anterior aspect of the ankle and lower leg.
Deep palmar crease
MedGen UID:
387849
Concept ID:
C1857539
Finding
Excessively deep creases of the palm.
Cleft upper lip
MedGen UID:
40327
Concept ID:
C0008924
Congenital Abnormality
A gap or groove in the upper lip. This is a congenital defect resulting from nonfusion of tissues of the lip during embryonal development.
Cleft palate
MedGen UID:
756015
Concept ID:
C2981150
Congenital Abnormality
Cleft palate is a developmental defect of the palate resulting from a failure of fusion of the palatine processes and manifesting as a separation of the roof of the mouth (soft and hard palate).
Tessier number 4 facial cleft
MedGen UID:
1642051
Concept ID:
C4703420
Congenital Abnormality
The cleft lip is midway between the philtral ridge and the commissure of the mouth. The cleft is lateral to the normally shaped and placed nasal ala and passes onto the cheek. The cleft extends through the lower eyelid lateral to the punctum. The lacrimal system and inner canthus are normal. Microphthalmia may be present. The alveolar cleft passes between the lateral incisor and canine, as in the Number 3 cleft. The cleft passes around the pyriform aperture and continues through the portion of the maxillary sinus medial to the infraorbital foramen. The cleft terminates at the medial end of the inferior orbital rim. There is severe vertical soft tissue deficiency in a Number 4 cleft, with the medial margins of the cleft lip extending directly into the medially placed cleft of the lower eyelid. Within the medial segment of the right-sided cleft lip, muscle elements are apparently absent. Muscle bunching is noted in the ipsilateral lateral lip segment, as is seen in a typical unilateral cleft lip. The anatomically normal nasal ala is superiorly displaced in association with a severe deficiency in the overall nasal length. Marked dystopia of the right globe results in its inferior displacement into the medially deficient orbital floor and inferior rim. Both globes are otherwise normal. The complete palatal cleft passes through the maxilla medial to the infraorbital foramen and extends to the medial portion of the inferior orbital rim without evidence of an intact maxillary sinus. Bony septation persists medially, thereby separating the nasal cavity from the orbit, maxillary sinus, and mouth, which are contiguous. Marked midfacial hypoplasia is present. The cleft is manifest as asymmetry of the body of the sphenoid; it is smaller on the right, with asymmetric placement of the pterygoid plates relative to the midline. The orbital floor cleft has no communication with the inferior orbital fissure. The cleft does not extend to the skull base, but there is marked facial asymmetry associated with plagiocephaly.
Congenital ocular coloboma
MedGen UID:
1046
Concept ID:
C0009363
Congenital Abnormality
Coloboma is an eye abnormality that occurs before birth. Colobomas are missing pieces of tissue in structures that form the eye. They may appear as notches or gaps in one of several parts of the eye, including the colored part of the eye called the iris; the retina, which is the specialized light-sensitive tissue that lines the back of the eye; the blood vessel layer under the retina called the choroid; or the optic nerves, which carry information from the eyes to the brain.\n\nColobomas may be present in one or both eyes and, depending on their size and location, can affect a person's vision. Colobomas affecting the iris, which result in a "keyhole" appearance of the pupil, generally do not lead to vision loss. Colobomas involving the retina result in vision loss in specific parts of the visual field. Large retinal colobomas or those affecting the optic nerve can cause low vision, which means vision loss that cannot be completely corrected with glasses or contact lenses.\n\nSome people with coloboma also have a condition called microphthalmia. In this condition, one or both eyeballs are abnormally small. In some affected individuals, the eyeball may appear to be completely missing; however, even in these cases some remaining eye tissue is generally present. Such severe microphthalmia should be distinguished from another condition called anophthalmia, in which no eyeball forms at all. However, the terms anophthalmia and severe microphthalmia are often used interchangeably. Microphthalmia may or may not result in significant vision loss.\n\nPeople with coloboma may also have other eye abnormalities, including clouding of the lens of the eye (cataract), increased pressure inside the eye (glaucoma) that can damage the optic nerve, vision problems such as nearsightedness (myopia), involuntary back-and-forth eye movements (nystagmus), or separation of the retina from the back of the eye (retinal detachment).\n\nColobomas involving the eyeball should be distinguished from gaps that occur in the eyelids. While these eyelid gaps are also called colobomas, they arise from abnormalities in different structures during early development.\n\nSome individuals have coloboma as part of a syndrome that affects other organs and tissues in the body. These forms of the condition are described as syndromic. When coloboma occurs by itself, it is described as nonsyndromic or isolated.

Colobomas may be present in one or both eyes and, depending on their size and location, can affect a person's vision.\n\nPeople with microphthalmia may also have other eye abnormalities, including clouding of the lens of the eye (cataract) and a narrowed opening of the eye (narrowed palpebral fissure). Additionally, affected individuals may have an abnormality called microcornea, in which the clear front covering of the eye (cornea) is small and abnormally curved.\n\nBetween one-third and one-half of affected individuals have microphthalmia as part of a syndrome that affects other organs and tissues in the body. These forms of the condition are described as syndromic. When microphthalmia occurs by itself, it is described as nonsyndromic or isolated.
