Endoscopic sinus surgery (ESS) is an important treatment modality for chronic rhinosinusitis (CRS). However, its effect on olfaction remains controversial.

A systematic literature search in the PubMed, EMBASE and Cochrane Library databases was conducted to identify studies that assessed change in olfaction after ESS in patients with CRS.

Search terms were related to paranasal sinus diseases, smell and endoscopy.

The extracted data included authors, publication year, study type, age, sex, diagnostic criteria, surgical mode, sample size, follow‐up time, olfaction measurement tool and outcome.

We analysed the olfactory changes as continuous variables.
