Abstract

Concha bullosa (CB) alters the intranasal anatomy and may influence the buffering of inhalant allergens and the inflammatory microenvironment central to chronic rhinosinusitis (CRS). By investigating the link between allergies and CB, we can examine this theoretical benefit, which has implications on the extent of resection in endoscopic sinus surgery. Forty-three adults treated between 2010 and March 2014 with chronic sinonasal symptoms were retrospectively analyzed by skin prick allergy testing, maxillofacial computed tomography scan, and Lund-Mackay score. x03C7;2 analysis and t tests were employed to determine statistical significance. Subjects were divided into 30 positive cases and 13 pan-negative allergy controls. No difference in CB prevalence was observed between those with positive (70%) and those with negative (69.2%) allergy tests (p = 0.93). Furthermore, no association between CB and Lund-Mackay score was identified (p = 0.69). Overall, 83.3% of CB were located in the middle turbinate, 16.7% in the superior turbinate, and 20% occurred in the middle turbinate bilaterally. Although an enlarged, pneumatized turbinate could function as a physical barrier to inhalant allergens, documented allergies demonstrate no associ...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
