Orbital cyst formation associated with Gelfilm use

Two patients developed cystic lesions in the anterior orbit 21 and 26 months after repair of blow-out fracture with orbital floor Gelfilm implants. Both patients had associated motility disturbances. Both lesions were surgically excised and found to be cystic in nature and filled with glistening gelatinous material consistent with partially absorbed, encysted gelatin film (Gelfilm). Histologically, a fibrous capsule was present; the contents of the cyst were not pathologically identifiable since they dissolved during fixation. Postoperatively, the motility disturbances improved in each patient.
