The purpose of this study was to investigate whether a delay in operative management of frontal sinus fractures is associated with increased risk of serious infections.
Retrospective chart review was performed of 242 consecutive patients with surgically managed frontal sinus fractures who presented to the R Adams Cowley Shock Trauma Center between 1996 and 2011. Collected patient characteristics included demographics, surgical management, hospital course, and complications. All computed tomographic imaging was reviewed to evaluate involvement of the posterior table and nasofrontal outflow tract. Serious infections included meningitis, encephalitis, brain abscess, frontal sinus abscess, and osteomyelitis. Delayed operative interventions were defined as procedures performed more than 48 hours after admission. Adjusted relative risk estimates were obtained using multivariable regression.
There were 14 serious infections (5.8 percent). All patients with serious infections had both involvement of the posterior table and nasofrontal outflow tract injury. The cumulative incidence of serious infection in these patients was 10.8 percent. After adjustments for confounding, multivariable regression showed that operative delay beyond 48 hours was independently associated with a 4.03-fold (p < 0.05) increased risk for serious infection; external cerebrospinal fluid drainage catheter use and local soft-tissue infection conferred a 4.09-fold (p < 0.05) and 5.10-fold (p < 0.001) increased risk, respectively. 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.
