Conclusions
Our results suggest that Type 2-high conditions (CRSwNP, asthma, NERD),
high visit frequency, short time between baseline visit and ESS, and
immunodeficiency or its suspicion increase likelihood of revision ESS at
individual level. Moreover, age and the number of preoperative visits
predict non-linearly the revision ESS risk. These data could be usable
in clinical decision making and patient counseling.
