| Popis: | Purpose To evaluate the outcomes of orbital hydrogel expanders in the management of congenital anophthalmia. Methods In this retrospective one-armed cohort study, a chart review was performed of eight children with congenital anophthalmia who underwent orbital expansion using orbital hydrogel tissue expander from January 2006 to July 2018. Computed tomography (CT) of orbital parameters was evaluated before and after surgery. Changes in the orbital parameters were correlated with clinical factors. Results The study sample comprised 11 anophthalmic orbits of eight children (seven males, one female; median age = 12 months), with a median postoperative follow-up of 3.8 years. The anophthalmic orbital parameters after hydrogel expander implantation improved significantly compared to preoperative assessment as follows: mean orbital height improved from 21.7 mm to 25.4 mm (P Conclusions Orbital hydrogel expander can improve the orbital development in congenital anophthalmia. However, the enlargement is not as extensive as that observed in the normal orbit. Orbital expanders associated with external conformers were not sufficient to induce normal growth of lids and fornix. |
