| Purpose Solid hydrophilic tissue expanders have been designed for orbit expansion, providing a new option for the treatment of pediatric orbital volume deficit. Self-inflating hydrogel expanders were used in this study to evaluate the cosmetic outcomes for pediatric patients with congenital microphthalmia and acquired anophthalmia.
Methods Osmed spheric, hemispheric and injectable pellet expanders were implanted in 20 patients aged 3 months to 10 years (17 patients with congenital blind microphthalmia, 3 with acquired anophthalmia).
Results After 6~24 months of follow-up, the previously contracted sockets were enlarged, the prosthesis fit for all patients, and the aesthetic results were pleasing.
Conclusions Self-inflating hydrogel is a safe, quick, and less invasive material for treatment of congenital microphthalmia and acquired anophthalmia. |
