Orbital emphysema following removal of bilateral midfacial implants.

A 36-year-old man with Crouzon syndrome was referred post-operatively with unilateral painful limitation of eye movements and proptosis following removal of bilateral malar and orbital rim implants. Further investigation revealed right inferior orbital emphysema, caused by the intra-operative entrance of hydrogen peroxide through a suspected perforation of the orbital septum. The symptoms settled with conservative management.
