Orbital and Nasal Complications Secondary to Inhaled Cocaine Abuse

The abuse of inhaled cocaine causes chemical sinus pathology by secondary midfacial destruction and necrosis. When midfacial necrosis is already established, other complications may occur related to the proximity of structures such as the orbit or optic nerve. We present the evolution of a young cocaine addict with midfacial destruction, who has had a subperiosteal abscess and optic neuritis over the course of the years. Differential diagnosis and management of these complications are also discussed. © 2010 Elsevier Espana, S.L. All rights reserved.
