Use of antibiotics for expansion of the Merocel packing following endoscopic sinus surgery.
Sinus packs that are used for hemostasis and the prevention of synechiae following endoscopic sinus surgery frequently get colonized with bacteria from the infected sinus, which increases the risk for infection. This study was conducted in an attempt to characterize the bacterial flora of the chronically infected sinus, and to evaluate whether direct installation of antibiotics into the sponge inhibits bacterial growth. Bacteria were cultured from 89% of the sinuses at surgery, and in 67% of the cases, the same bacteria were recovered from the sinus dressings one week later. When the Merocel sinus dressing was expanded with a combination of polymyxin, neomycin and hydrocortisone at the time of surgery, a 36% decrease in bacterial growth was observed, along with a decrease in the severity of pain associated with removal of the pack. This supports the concept of using an antibiotic for the expansion of the sponge following endoscopic sinus surgery.
