Chronic rhinosinusitis: allergy and sinus computed tomography relationships
1University of California, San Francisco, USA.
Summary
Most patients with chronic rhinosinusitis have allergies, particularly to perennial allergens like dust mites. Identifying and treating these allergies may help prevent recurrent sinus problems.
Area of Science:
- Otolaryngology
- Allergy and Immunology
Background:
- Chronic or recurrent rhinosinusitis management is complex, involving medical and anatomical factors.
- The link between allergies and rhinosinusitis requires further clarification.
Purpose of the Study:
- To elucidate the roles of perennial and seasonal allergens in chronic rhinosinusitis.
- To understand the prevalence of allergies in patients with refractory chronic rhinosinusitis.
Main Methods:
- Retrospective review of 200 patients with chronic rhinosinusitis undergoing functional endoscopic sinus surgery.
- Pre-operative allergy testing for inhalant allergens and sinus CT imaging with standardized grading.
Main Results:
- 84% of patients tested positive for allergies; 60% had significant sensitivity.
- 52% had multiple allergen sensitivities, with a predominance of perennial allergens (e.g., house dust mite).
Conclusions:
- A high prevalence of concomitant allergy exists in patients undergoing surgery for chronic rhinosinusitis.
- Perennial allergies may significantly contribute to the development and persistence of rhinosinusitis.
- Early allergen identification and intervention could be key in preventing chronic rhinosinusitis.
