Title: Functional aspects of the hyperteleorbitism treatment
In congenital malformations, Hyperteleorbitism can be present both in fusion errors of embryonic processes (Dysplasias) and in Craniofaciestenosis (Dysostosis). It has variable degrees of presentation and in the last 70 years it has received several treatment proposals.
Adapting the treatment of Hyperteleorbitism to the anatomical and functional needs of each type of manifestation, we analyze the main aspects of the available techniques:
· In cases of Hyperteleorbitism in which there is meningoencephalocele or the floor of the anterior cranial fossa is very low, the concomitant expansion of the skull is mandatory, to allow the accommodation of the brain tissue in response to the medialization of the orbits. Failure to observe this precaution triggers postoperative endocranial hypertension.
· Osteotomies that reach the orbital floor (Tessier Box) cause entrapment of tooth germs and major sequelae of the middle third of the face growth.
· The craniofacial bipartition (Van Der Meulen) respects the morphofunctional units of the face, adapting the vectors of masticatory forces and ensuring stable results throughout growth.
· The isolated mobilization of the medial walls of the orbits when performed in grade 1 and 2 hyperteleorbitism does not cause enophthalmos and is a resolutive and little invasive procedure.
