APPROACH
Special considerations influencing ORIF
Aesthetics
Internal Derangemen
t of the Sinus
Intracranial Injuries
Other maxillofacial
injuries
Special considerations influencing ORIF
Aesthetics : Loss of forehead contour
Physical Examination may be inconsistent w/ the severity of the fractures
Early open surgery is preferable.
A depressed anterior table may not lead to a noticeable forehead flattening.

TREATMENT
•PERIOPERATIVE•Lumbar drain
•CSF Rhinorrhea
•Broad spectrum IV Antibiotics
•Contaminated Wound
ANTIBIOTIC Therapy
• Frontal Sinus Fractures are CONTAMINATED
The use of additional antibiotics outside the perioperative timeframe does not reduce the rate of postoperative infections; however, such antibiotic use may be warranted in cases of severe facial trauma with multiple open fracture wounds

N: 242 pxs (1996-2011)
Relative risk estimates were obtained using multivariable regression.
Antibiotic use beyond 48 hours postoperatively was not associated with fewer infections.
Delay in operative management of frontal sinus fractures in patients requiring operative intervention is associated with an increased risk for serious infections.
Continued antibiotic prophylaxis beyond the perioperative period provides little benefit in preventing serious infections.
