The effects of OT after sinonasal surgery.
There were no significant differences in TDI scores between the two groups at baseline, and there were no significant differences in odor threshold, discrimination, or identification subset tests.
Following sinonasal surgery, patients who underwent OT showed a significant increase in TDI scores after 3 months. The subset analysis of the TDI scores showed that the odor threshold, discrimination, and identification scores increased significantly in the OT group. The non-training group also showed improvement in the threshold score compared with the other scores, but the difference was not statistically significant. In either group, there were no significant variations in VAS scores between the test times. Table 2 shows the descriptive statistics for the outcomes.
OT patients exhibited significantly higher total TDI scores compared to non-OT patients at the end of 3 months. In the subset analysis, the odor identification scores differed between the two groups after 3 months. Table 1 and Figure 1 show the descriptive statistics of the findings.
