Could a 'Sinus poop Transplant' cure chronic sinusitis? new trial says maybe.

This study tests a new treatment for chronic sinusitis, a long-lasting sinus infection that doesn't get better with standard care. Researchers will take healthy bacteria from a donor's sinuses and transfer them into the sinuses of 80 patients, after a special sinus wash. The goal is to see if this can restore a healthy bacterial balance and improve symptoms like pain, congestion, and loss of smell.
