There seems to be an increasing number of patients I see with MRSA sinusitis. Not many, but definitely not rare. These patients are understandably very concerned with how to treat their MRSA sinusitis.
Beyond the usual protocol that applies to any MRSA infection, if the sinusitis is severe, sinus surgery is recommended for 3 main reasons.
1) Get the infection cleaned out surgically (much like draining an abscess of the skin)
2) Enlarge the openings of the sinus cavity to allow good post-op topical treatment in order to potentially avoid oral and IV antibiotics (though they still may be needed)
3) Sinus infection can be carefully followed endoscopically in the future
By opening up the sinuses, topical treatment can be performed that is sometimes more effective that IV or oral routes as higher concentrations of medication can be delivered right to the area of concern (instead of oral or IV routes which go throughout the entire body causing side effects).
Such topical treatment include:
• Saline flushes (Neilmed Sinus Rinse is our preferred method though irrigation devices shown below are also fine)
• Bactroban Cream or Cortisporin Ointment injection directly into the sinus cavity
• Antibiotic flushes to the sinus cavity
• Chemical saline flushes to the sinus cavity (my favorite being No-Tears Johnson's Baby Shampoo - 1 tsp in 250 cc of saline)
Debridement of the sinus cavity can also be easily performed after sinus surgery in the office.
Once the active MRSA sinusitis infection has cleared, continued topical treatment with daily saline nasal flushes help prevent future sinus infections.
