Chronic Rhinosinusitis May Respond Better to Topical Irrigations
Topical drug therapy is emerging as a possible treatment of choice for postoperative use in patients with chronic rhinosinusitis (CRS). Compared with the oral route, topical administration delivers more active drug directly to the site of infection without the risk of systemic side effects.
Studies of culture-directed antibiotic sprays have suggested that topical therapies such as mupirocin irrigation may be effective in treating both stable and acute exacerbations of CRS. Additionally, high-dose topical steroids are now being widely used by rhinologists as maintenance therapy for patients with refractory CRS with nasal polyps. In some instances, antifungals are being used topically as well. While many patients benefit from a single type of irrigation, others have more complex disease and require an irrigation that includes both antimicrobials and steroids.
The Sprays Must Not Be Cold
One particular aspect of the topical delivery of prescription drugs that might be somewhat problematic concerns their storage and the temperature at which they are administered. Many of the medicated irrigations being used today require refrigeration. However, administering a cold spray can be both unpleasant and unhealthy, so patients must be counseled on properly warming their medication before use. These irrigations must be allowed to warm naturally at room temperature. Heating them on a stovetop or in a microwave oven is not recommended since the intensified warming may alter the effectiveness of the drug.
We recently studied several standard formulations of medicated nasal solutions (containing budesonide, mupirocin, amphotericin and tobramycin) and found that it takes more than two hours for these solutions to completely reach room temperature after they are removed from the refrigerator. Therefore, it seems prudent to advise patients to wait at least 45 minutes after taking their medication from the refrigerator before using it.
One complication of cold irrigations in particular that demands attention is a condition called paranasal sinus exostoses. In patients with this new diagnostic entity, which was recently characterized by Cleveland Clinic rhinologists(1), multiple growths arise in postoperative sinus cavities as a result of contact with cold irrigation solutions. These exostoses are analogous to exostoses of the external auditory canal that are associated with cold-water surfing (“surfer’s ear”).
On endoscopy, these exostoses characteristically appear as multiple cysts, but they are actually hard to palpation with an instrument. On CT, they appear as small bony growths on the luminal surfaces of the involved sinuses. Once formed, they appear to be permanent, but they do not progress further after discontinuation of cold irrigations. They do not require surgical intervention unless the lesions progress to the point of being obstructive.
Newer methods of formulating medicated solutions by mixing a dry-powder form of a drug with room-temperature saline are being investigated. But until they become widely available, patients should be warned of the risks associated with cold irrigations and educated on the proper way to warm the nasal irrigation.

Measuring and Reporting Outcomes Promotes Quality Improvement
To encourage continuous improvement, promote transparency and highlight the quality of our care, Cleveland Clinic began publishing annual Outcomes reports several years ago. These reports summarize objective data on the performance of more than a dozen of our disease-based, patient-centered institutes, including the Head & Neck Institute.
One example of our measured outcomes concerns survival for patients treated for nasopharyngeal carcinoma.
The data on these patients clearly shows the importance of early detection. As of 2012, patients with stage I/II disease had significantly better overall and disease-specific survival at 10 years than did patients with stage III/IV disease. Our survival data in the patient population compares favorably with benchmark data (not shown but available).
