A few days ago I operated on a young man from Hangzhou who had hyposmia for 6 months. Less than 2 weeks after the surgery, the young man’s sense of smell was completely restored and I asked him to continue the medication to consolidate the effect. There are two types of hyposmia: 1) nerve loss (bad nerve); 2) inflammation and blockage. The former is ineffective, the latter is promising. The latter may occur in the former case if left untreated for a long time. Recently, 2 more people with bad sense of smell had good sense of smell 2-3 weeks after surgery.
