Hypertelorism
The Hypertélorisme is a Syndrome characterized by cranio-facial malformations being characterized by an enlarging of the small wing of the Sphénoïde, involving a widening of the distance interorbitaire (interocular space is normally about equal to the width of an eye) and root of the nose.
It is observed in many hereditary diseases, often accompanied by a Mental deficiency, ocular problems (Colobome…), of Syndactylie (one or more finger (S) S welded (S) between them), and of cranial anomalies as observed in the Disease of Crouzon).
A light hypertelorism is frequent and normal at the newborn whose nose is not developed yet. Tables of measurement of the distances interpupillaires (IP) make it possible to confirm a real hypertelorism. It is possible to evaluate the IP starting from the internal and external (IC) distances intercanthales (OC) of the eyes thanks to the formula IP = 0.17 + 0.59 IC + 0.41 OC . Radiology allows a more precise measurement.
Treatment
The cranial surgery can contribute to the bringing together of the orbits by orbital mobilization, or bipartition, or to repair certain nasal anomalies .
