The Relationship between External Bony Defects and Widened Lateral Interorbital Distance in Frontoethmoidal Encephalomeningocele

ConclusionThere is an association between the EL ratio and widening of the LIOD. An EL ratio greater than 23% could be used to moderately predict a wide LIOD. A large external bony defect may be associated with lateral displacement of the orbit causing true hypertelorism. Therefore, orbital translocation must be considered in patients with a wide LIOD.
