This procedure treats vocal cord scarring, thinning, or atrophy that affects voice quality. PRP (Platelet-Rich Plasma) and fat are both natural substances derived from the patient's own body. Fat can help restore lost volume and cushion the vocal folds, while PRP, which is rich in growth factors, supports tissue healing and regeneration. When used together, they can improve vocal fold pliability and vibratory function, leading to a stronger, clearer voice.

The procedure is done under general anesthesia using a surgical microscope. A small incision is made in the vocal fold surface, and fat (usually harvested from the abdomen or thigh) and/or PRP are injected into the vocal fold muscle. Recovery typically involves voice rest for several days to allow the tissues to settle and heal. Most patients gradually resume speaking, and the voice often improves over several weeks. Follow-up may include voice therapy to optimize the results. Because fat may be reabsorbed over time, some patients may need a second procedure later.
