Analysis of illness: This situation may be that there is still edema after operation. At this time, it may be that the left nasal cavity recovered quickly and the right nasal cavity did not fully recover. Because the left and right nasal cavities are not exactly the same.

Suggestion: If the postoperative time is not long, you can continue to observe. If the ventilation is seriously blocked, go to the hospital where the operation is performed to check the inside of the nasal cavity, and then wash the nose with physiological seawater.
