Orbital hypertelorism: Modification of the craniofacial osteotomy line

Abordagem cirúrgica do hiperteleorbitismo na displasia craniofrontonasal

“…Since the first description of craniofrontonasal dysplasia 8 , the surgical treatment of hyperteleorbitism in these patients has been restricted only to reports of isolated cases and to retrospective series in the international context [12][13][14][15][16][17] . Although there are national publications 18,19,22,23 that address the surgical correction of hyperteleorbitism of several craniofacial deformities together, this is the first Brazilian study that brings the peculiarities of the intracranial and extracranial interventions performed for the treatment of hyperteleorbitism in patients with craniofrontonasal dysplasia .…”

“…Although there are national reports on the treatment of hyperteleorbitism by extracranial osteotomies 22,23 , the procedures of choice have been the orbital box osteotomy and facial bipartition [17][18][19]21 , as both techniques allow the three-dimensional mobilization of the target structures and, therefore, the approach of a broad spectrum of clinical presentation of hyperteleorbitism. In the particular scope of craniofrontonasal dysplasia, Kawamoto et al 17 considered that facial bipartition enabled a better correction of craniofacial deformity when compared with orbital box osteotomy.…”

Craniofacial surgery for orbital malformations

“…15,16 A variety of orbital osteotomies have been described, which may involve movement of one, two, three, or four orbital walls, unilaterally or bilaterally depending on the severity and nature of the deformity. 17,18 Of paramount importance in orbital osteotomies is the management of the medial canthal ligament. This is best left attached to its bony base and great care must be taken in subperiosteal dissection to avoid encroaching on the area of the medical canthus.…”
