Pressure Onto the Orbital Walls and Orbital Morphology in Orbital Floor or Medial Wall Fracture: A 3-Dimensional Printer Study.

The purposes of this study were to compare the pressure onto the orbital floor and medial orbital wall between 3-dimensional printer skull models with unilateral orbital floor and medial orbital wall fractures and to compare the morphology of the orbital floor and medial orbital wall between patients with unilateral orbital floor and medial orbital wall fractures. The skull models were created based on computed tomographic (CT) data obtained from every 10 patients with unilateral orbital floor and medial orbital wall fractures. The orbital spaces of these models were filled with silicone, the silicone surface was pushed down, and pressures onto the orbital floor and the medial orbital wall were measured.

Treatment strategies for orbital gas-producing necrotizing fasciitis secondary to odontogenic maxillary sinusitis: Technical notes.

This paper presents treatment strategies for orbital necrotizing fasciitis (NF) in a case of a 33-year-old male diagnosed with orbital NF, which developed after dental root canal treatment. Although orbital NF is rare, it is rapidly progressive and can easily lead to the loss of tissue and visual function, sometimes to a life-threatening extent. Prompt and adequate treatment has been a challenge yet remains quite essential.
