  • Title: Infection after insertion of alloplastic orbital floor implants.
    Author: Mauriello JA, Hargrave S, Yee S, Mostafavi R, Kapila R.
    Journal: Am J Ophthalmol; 1994 Feb 15; 117(2):246-52. PubMed ID: 8116755.
    Abstract:
    Ten patients developed infections after alloplastic implantation (nine silicone, one gelatin film [Gelfilm] implant) for orbital floor fracture repair. Infection resulted from the following: (1) dental surgery, (2) upper respiratory infection, (3) inferior extrusion of a retained implant into the maxillary sinus with a fistulous tract into the inferior conjunctival fornix, (4) rhinoplasty, (5) snorting cocaine and other drugs, (6) postoperative infection after orbital floor repair, and (7) medial implant migration resulting in chronic dacryocystitis. In all ten patients, implants were removed because of orbital abscess, recurrent infection, or chronic low-grade infections. Microbiologic culture of removed implants disclosed Staphylococcus aureus, S. epidermidis, Serratia marcescens, and Pseudomonas aeruginosa as the offending organisms. The main complication of infection included severe cicatricial ectropion of the lower eyelid in three patients. The final globe position was not adversely affected by implant removal performed from five months to 20 years after insertion. Guidelines for prevention and management of orbital implant infections based on these ten patients are presented.
