Summary

This study tests two ways to give platelet-rich plasma (PRP) to adults who have had poor smell for over three months. One method uses a soaked sponge placed in the nose, the other uses a small injection. Sixty participants will get one treatment and then do daily smell training for three months to see which approach works better and is more comfortable.
