title: Refinement of the correction of orbital hypertelorism.
abstract: The objective of this article was to explore the effect of paraorbital soft-tissue expansion before orbital osteotomies and medial translocation by combined intracranial-extracranial approach. Tissue expansion was implanted in the zygomatic and temporal region 3 weeks before traditional operation in 2 cases of severe orbital hypertelorism. The measurements of interorbital and intercanthal distance were studied preoperatively and postoperatively by three-dimensional computed tomography. The interorbital distance of the 2 patients decreased from 4.4 and 3.2 cm to 2.0 and 1.4 cm, respectively. The intercanthal distance decreased from 6.7 and 4.8 cm to 5.0 and 3.8 cm, respectively. The paraorbital soft-tissue-expansion technique may be an effective technique for the stability of the corrected orbital framework and the prevention of reoccurrence in severe cases of orbital hypertelorism.
