Nasal plastic surgery is a stage prone to complications within one week. Infection may be caused by incomplete cleaning after fat implantation, or blood vessels may be damaged and bleeding may be caused by poor operation, and the sense of smell may be temporarily lost in a small probability. Under normal circumstances, there will be nasal congestion and runny nose after operation, which will disappear after a few weeks. The other is that the filler is skewed and the nose columella is not straight.
