Can hypertelorism be corrected?
Orbital hypertelorism can be treated surgically. For minor cases of orbital hypertelorism, your child’s surgeon may recommend an extracranial correction. In an extracranial correction, the bones of the inner portions of the nose and eye socket are brought closer together without going inside the skull.
What does hypertelorism look like?
In-Depth Look into Hypertelorism Any process that interferes with this movement, such as abnormal development of the bones of the forehead and the base of the skull, premature fusion of the bony plates of the skull or a cleft between the bones of the nose or upper face can result in hypertelorism.
Is hypertelorism genetic?
Teebi type hypertelorism is a rare genetic disease characterized by hypertelorism with facial features that can closely resemble craniofrontonasal dysplasia (see this term), such as prominent forehead, widow’s peak, heavy and broad eyebrows, long palpebral fissures, ptosis , high and broad nasal bridge, short nose, low …
Is hypertelorism a malformation?
Ocular Hypotelorism or Hypertelorism Hypotelorism (narrowing of the intraorbital distance) may be associated with central nervous system malformation. Ocular hypertelorism is a term indicating increased separation between the bony orbits, usually greater than two standard deviations above the mean.
What causes hypertelorism?
Causes of hypertelorism The following are some of the most common causes: A mass or growth pushing the two orbits apart. Abnormal development of the bones of the forehead and base of skull. Premature fusion of the bony plates of the skull.
Does Down syndrome have hypertelorism?
Mongoloid slant, epicanthal folds, hypertelorism, simian crease, flat nasal bridge, and microcephaly were observed in >60% of cases.
What does hypertelorism mean?
The term hypertelorism means an increased distance between two body parts. Greg applied it for the eyes and termed it as “ocular hypertelorism” in 1924 to signify widely placed eyes. He used interpupillary distance (IPD) to record its presence.
Do babies with Down syndrome have a nasal bone?
Detectable nasal bones were seen in 10 fetuses with Down syndrome and 222 euploid fetuses. A receiver operating characteristic curve for the biparietal diameter-nasal bone length ratio showed that a value of 9 or greater detected 100% of fetuses with Down syndrome and 22% of euploid fetuses.
What is the role of surgery in hypertelorism?
Surgery in hypertelorism is mainly for cosmetic purposes. It requires a major surgery that has to approach through intracranial as well as extracranial route. The pioneer in surgery for hypertelorism was Paul Tessier.
What is orbital hypertelorism?
Orbital hypertelorism is defined as an increased distance between the orbits, with true lateral displacement of the orbits. Hypertelorism is associated with underlying craniosynostosis syndromes, median facial clefting, and some other genetic syndromes.
How is bilateral symmetrical hypertelorism corrected?
Symmetrical hypertelorism The patient in Figure 10has bilateral symmetrical hypertelorism. This should ideally be corrected by medial orbital shift using “box osteotomy” technique. The planning has been shown on the three-dimensional computed tomography (CT) scan image in the middle row.
What are the complications of orbital hypertelorism correction surgery?
The main complications of both surgeries for orbital hypertelorism correction include excessive bleeding, risk of infection and cerebrospinal fluid leaks. Rare events also include blindness, visual disturbances, ptosis and diplopia.
