We are all familiar with patients who undergo a seemingly successful FESS but, in spite of this, have persistent smell dysfunction postoperatively. This study compares a surgical group with a control group, measuring olfactory function pre and postoperatively using Sniffin Sticks. In the surgical group, the number of patients with anosmia postoperatively improved from 34% to 18% and the number of patents with normosmia improved from 23% to 39%. Patients who underwent a septoplasty at the same time as their FESS had better outcomes in terms of smell, and the patients with CRSwNP had worse outcomes. Overall, while a lot of patients had some improvement in their olfactory function, only 50% had a return comparative to that of normal controls. This is useful to allow us to counsel our patients preoperatively as to what expectations they can have regarding their smell function postoperatively.
