Résumé
<p><b>OBJECTIVE</b>To explore the possibility of para-orbital soft-tissue expansion, before orbital osteotomy and medial translocation procedures with a combined intracranial-extracranial approach.</p><p><b>METHODS</b>Tissue expansion in the region of the zygomatic and temporal has been undergone for 3 weeks before the traditional intracranial-extracranial approach for orbital osteotomy and medial translocation in two patients. The healing between the orbital bone was studied with measurement of interorbital distance and three-dimensional CT.</p><p><b>RESULTS</b>The inter-orbital distance of the two patients decreased from 4.4 cm and 3.2 cm to 2.0 cm and 1.4 cm. The intercanthal distance decreased from 6.7 cm and 4.8 cm to 5.0 cm and 3.8 cm.</p><p><b>CONCLUSIONS</b>The para-orbital soft-tissue expansion technique may be an effective technique for the stability of the corrected interorbital distance in orbital hypertelorism.</p>
