title: The value of three-dimensional printing modelling for surgical correction of orbital hypertelorism.
abstract: Orbital hypertelorism is defined as an increased distance between both medial and lateral sides of the orbits. Most common causes are frontonasal malformations, craniofacial fissures, encephalocele and a miscellaneous group of various syndromic or chromosomal disorders. Surgical correction of orbital hypertelorism is still challenging. The present report describes a case of severe orbital hypertelorism of an 11-year-old boy, where surgical correction was planned using three-dimensional printing modelling. This approach allowed reducing time of surgery, accurately planning the location of the osteotomies and precontouring the osteosynthesis material. Three-dimensional models are very helpful tools in planning complex craniofacial operative procedures.
