Pathophysiology of Chronic Rhinosinusitis
Approximately 25% of patients with olfactory disturbances have CRS. Camilo Reyes, MD, a current fellow in the rhinology-skull base surgery program at the Medical College of Georgia-Augusta University in Augusta, Ga., measured improvement in olfactory disturbances in patients with CRS using the Sinonasal Outcome Test (SNOT-22) scores at first and last postoperative visit. The study included 134 patients with CRS: 87 with eosinophilic CRS (eCRS) and 47 with non-eosinophilic CRS (neCRS). The researchers found that patients with eCRS had higher preoperative olfactory experience than patients with neCRS. Additionally, approximately two-thirds of patients in both groups demonstrated subjective improvement in olfaction after surgery. Thus, both the study group and control group had a significant post-surgery improvement in olfactory experience.
