General Overview of Condition
- Rare condition in which the midface does not develop normally
- Affects the head and face
- May cause widely spaced eyes, a flat broad nose, and a vertical groove in middle of face
- Cause is not known but can be sporadic or familial
- Anomalies explained by single malformation
- Nasal capsule fails to develop properly causing disruption in the positioning in the eyes and lack of formation of nasal tip
- Considered nonspecific developmental field defect
- Most cases sporadic
- Some reports of familial aggregation but may be misdiagnosis
- Reported in dup(2q) syndrome
- Can occur as one feature in multiple malformation syndrome with recurrence risk is for syndrome
- Variability in severity of expression
- Lateral displacement of inner canthi
- Widown's peak
- Defect in midline frontal bone (cranium bifidum occultum)
- Varies from notched broad nasal tip, divided nostrils with hypoplasia, absence of prolabium and premaxilla with cleft lip
- Broad nasal root
- Lack of formation of nasal tip
- Occasional abnormalities
- Accessory nasal tags
- Anomalies of optic disk, optic nerve, retina, or eye (colobomas, cataracts)
- Preauricular tags, low-set ears
- Conductive deafness
- Mental deficiency (8-20%)
- Seems to be more severe when extracephalic anomalies occur or when hypertelorism is very severe
- Probability low if features above are not as sever
- Frontal cutaneous lipoma or lipoma of corpus callosum
- Agenesis of corpus collosum
- Anterior basal encephalocele
- Tetralogy of Fallot
- Cleft lip and/or cleft palate
- Usually requires radical cosmetic surgery to repair
- Natural history and lifespan depend on severity and complications but usually not significantly different from expected
- Oculo-auricular-vertebral spectrum
- Frontofacionasal dysostosis - autosomal recessive inheritance
