Voice box injections using your own blood for vocal fold scars
Part of Ear, nose & throat clinical trials.
This study tests whether injecting a special solution made from your own blood (platelet-rich plasma) into your voice box can help improve voice problems from scars or thinning of the vocal folds. It is a simple injection procedure that may help your voice quality.
Summary written for real people, not researchers, by Clin2.

This trial tests if injecting platelet-rich plasma (PRP) during vocal cord surgery helps your voice heal faster and better. It is for adults with benign growths like polyps or nodules that haven't improved with voice therapy.
This study compares a standard scar treatment (subcision) alone versus combining it with either a carbon dioxide (CO₂) laser or platelet-rich plasma (PRP) from your own blood. It aims to see if adding these treatments improves atrophic acne scars more effectively.
This trial tests whether a preparation made from your own fat tissue can help heal scarred vocal cords and improve your voice. The fat cells are taken during a minor procedure and then injected into the vocal cords to reduce stiffness and improve vibration.
This trial tests if injecting a steroid combined with hyaluronidase into vocal cord lesions can help people with voice problems who cannot or will not do voice therapy. It's for those with small, non-cancerous growths who aren't candidates for surgery.
This study tests a voice implant device in people with permanent vocal cord weakness (UVFP) who have trouble closing their vocal cords. It aims to improve voice strength and reduce voice-related burden, while checking safety over the study period.
This study tests whether combining your own blood proteins (PRP) with a fractional CO2 laser can improve moderate-to-severe acne scars more than laser alone. You would have 3 treatment sessions spaced several weeks apart.
