First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether injecting a person's own platelet-rich plasma (PRP) into the nose can help restore smell in adults who have had smell loss for more than 6 months due to aging or head injury. Thirty participants will receive three PRP injections over four weeks and be followed for six months. The main goal is to see if enough people experience a meaningful improvement in their sense of smell.
