Platelet-rich plasma (PRP) injection to improve voice recovery after benign vocal fold surgery

Evaluating The Efficacy of Platelet Rich Plasma on Voice Outcomes Following Surgical Removal of Benign Vocal Fold Lesions

Not applicable Interventional Beni-Suef University · NCT07300800

This trial will try injecting platelet-rich plasma (PRP) into the operated vocal fold after microlaryngoscopic removal of benign lesions to see if adults recover voice quality faster and have less vocal fatigue.

What this trial studies

This interventional study enrolls adults aged 18–50 undergoing microlaryngosurgery for benign vocal fold lesions and allocates them to receive either a postoperative PRP injection to the operated vocal fold or conventional postoperative care. A total of 64 participants are divided into two groups of 32 and undergo baseline voice testing before surgery with follow-up assessments at 1 and 3 months. Outcome measures include perceptual voice rating (GRBAS), videostroboscopy, acoustic and aerodynamic analyses, and the Vocal Fatigue Index. The trial is conducted at Beni Suef University Hospital in Banī Suwayf, Egypt.

Who should consider this trial

Good fit: Adults aged 18 to 50 who are scheduled for microlaryngoscopic removal of benign vocal fold lesions (polyps, cysts, or nodules) after failing conservative management are the ideal candidates.

Not a fit: Patients outside the 18–50 age range, those medically unfit for surgery, those with malignant or non-lesion causes of dysphonia, or those managed without surgery are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, PRP injections could speed recovery of voice quality and reduce vocal fatigue after surgery, improving patients' daily communication and quality of life.

How similar studies have performed: Small clinical series and preclinical work have suggested PRP may aid vocal fold healing, but high-quality randomized evidence is limited.
