Abstract
A substantial number of patients with coronal synostosis who undergo frontoorbital advancement still require additional surgical treatment to correct increased intracranial pressure or unsatisfactory craniofacial structure. However, frontoorbital advancement currently requires elevation of the frontal as well as the orbital bone, which can result in a fragile dura mater and partial resorption of the advanced bone. Thus the dura is easily torn by dissection and the advanced bone is further resorbed and deformed during repeated craniofacial operations. To avoid these drawbacks and to create an easier second surgical treatment via the intracranial approach, a new technique for frontoorbital advancement is presented. In this technique frontoorbital bone is advanced as a single unit, without elevation from the underlying dura, by means of gradual distraction. The details of the technique and an illustrative case are reported.
