Key words
Chronic rhinosinusitis, sinonasal tissues, blood, group 2 innate
lymphoid cells, Lund-Mackay computed tomography scan score,
postoperative outcome
Key points
- The ILC2 prevalence in sinonasal tissues was correlated with that in
preoperative blood in eosinophilic chronic rhinosinusitis (eCRS) and
non-eCRS patients.
- The ILC2 prevalence in sinonasal tissues and in preoperative blood was
not correlated with the pre- or postoperative LMK-CT scores.
- The ILC2 prevalence in blood was decreased postoperatively in eCRS and
non-eCRS patients.
- The ILC2 prevalence in blood was decreased in the good outcome group
(postoperative LMK-CT score improvement rate ≥50%), but not in the
poor outcome group.
- A decreased ILC2 prevalence in blood after ESS may predict a good
postoperative outcome in eCRS and non-eCRS patients.
