Surgical Navigation and CAD-CAM-Designed PEEK Prosthesis for the Surgical Treatment of Facial Intraosseous Vascular Anomalies.

: Intraosseous vascular anomalies in the facial skeleton present significant diagnostic and therapeutic challenges due to complex anatomy. These anomalies represent about 0.5-1% of bony neoplastic and tumor-like lesions, usually presenting as a firm, painless mass.

Increased Reliability in Medial Canthal Tendon Reposition in Nasoorbitoethmoidal Fractures with Computer-assisted Surgery and Surgical Navigation.

Avulsion of the medial canthal tendon secondary to nasoorbitoethmoidal fractures leads to severe aesthetic and functional impairments. The tendon should be repositioned at the posterior lacrimal crest. Owing to the complexity of nasoorbitoethmoidal fractures, accurate location of this point during surgery can be challenging.
