Participant demographics
We enrolled 111 Korean participants (mean age: 45 ± 15.4 years; range:
18-74 years). There were 68 patients in the OT group (mean age: 45.6
years; 41 males and 27 females) and 43 patients in the non-OT group
(mean age: 44 years; 23 men and 20 women). Bilateral ESS was performed
on all patients, and septoplasty was performed in some patients (total
26 patients: 17 patients in the OT group and 9 patients in the non-OT
group) who had nasal septal deviation. After sinonasal surgery, there
were no issues other than some minor postoperative bleeding in the
hospital. There were no differences between the study groups at the
baseline assessment in terms of the LM score, initial TDI scores,
initial VAS score, or POSE score. Table 1 shows the descriptive
statistics of the findings.
