What is the impact of endoscopic sinus surgery (ESS) on improvement in olfaction and olfactory-specific quality of life (QOL)?
ESS improves CRS-related subjective olfactory dysfunction with greatest gains seen in those with poorer CT scores at baseline.

Background: Olfactory loss is a cardinal symptom of chronic rhinosinusitis (CRS), affecting 40% to 80% of patients. Objective assessment of olfactory improvement using instruments such as the 40-item smell identification test (SIT-40) or Sniffin’ Sticks has been reported in 23% to 68% of patients; however, few studies have focused on olfaction-specific QOL using questionnaires such as the questionnaire of olfactory disorders (QOD-NS).
Study design: Adult patients with CRS from an ongoing multi-institutional prospective cohort study were included.
