Contamination of sinus irrigation devices: a review of the evidence and clinical relevance.

BACKGROUND

The use of saline and topical medications in the treatment of chronic rhinosinusitis (CRS) is now common practice among otolaryngologists. Although high-level studies have consistently shown the benefit of saline in symptom improvement of CRS patients, to date, only lower-level evidence exists advocating a benefit of other topical medications.

METHODS

Recently, increased interest has emerged surrounding the devices used to deliver such therapies with mounting evidence consistently showing contamination with pathogenic organisms such as Staphylococcus aureus and Pseudomonas aeruginosa.

RESULTS

In addition, the potential for such contamination to cross-infect sinus cavities and lead to postoperative infections is also of concern.

CONCLUSION

This review examines the current evidence available concerning the issue of contamination and its clinical relevance and offers the otolaryngologist advice on patient education when dispensing such devices.
