The posterior auricular muscle complex graft as a porous orbital implant wrap: long-term follow-up over a 31-year period.

Purpose: Orbital implant exposures, infections, and extrusions can occur many years following enucleation or evisceration. This study analyzes complication rates following porous orbital implant wrapped with a posterior auricular muscle complex graft (PAMCG).

Methods: This is a retrospective study of patients who underwent orbital implantation following enucleation using this technique between 1992 and 2013.
