Management of odontogenic orbital cellulitis.
TL;DR: This work describes a series of patients with odontogenic orbital cellulitis, focusing on rate of abscess formation, need for surgical intervention, and imaging findings helpful for rapid diagnosis, as well as finding periapical lucency on CT can help identify this atypical origin of cellulitis.
