Reconstruction of complex orbitocranial deformities using bioresorbable mesh, sterilized orbital models, and in situ contouring.
OBJECTIVE
To assess the efficacy of bioresorbable mesh in reconstruction of orbitocranial deformities.


METHODS
A retrospective case series evaluating 6 orbits of 6 patients, ages 12 to 70 years old, with large multicontoured orbitocranial defects that were repaired using bioresorbable macroporous mesh. Both functional (presence of diplopia, ocular motility, exophthalmometry, and vertical globe position) and cosmetic outcomes were evaluated.


RESULTS
Follow-up time ranged from 20 to 48 months (mean, 29.1 months). After surgery, all patients reported cosmetically pleasing results. Diplopia resolved in all patients. Ocular motility, exophthalmos, enophthalmos, and vertical globe positioning improved in all patients. One patient had new onset of mild enophthalmos and hypoglobus after surgery. No cases of implant exposure or instability occurred. Complications included one patient with skin breakdown over a previous site of irradiation and one patient with ptosis requiring surgical correction.


CONCLUSIONS
Bioresorbable macroporous mesh combined with bone grafts is a useful and accurate method to reconstruct complex multicontoured orbitocranial defects.
