The goal of this clinical trial is to evaluate whether platelet-rich plasma (PRP) injections can improve voice outcomes after microlaryngosurgery in patients with benign vocal fold lesions. The main questions it aims to answer are: Does postoperative PRP injection improve vocal quality compared to conventional surgery alone? Does PRP injection reduce vocal fatigue and improve patients' voice-related quality of life? Researchers will compare 32 patients receiving PRP injections after surgery to 32 patients undergoing conventional surgery without PRP to see if PRP enhances recovery and voice function. Participants will: Undergo microlaryngosurgery to remove benign vocal fold lesions. Receive either a PRP injection to the operated vocal fold or standard postoperative care. Complete voice assessments before surgery and at 1 and 3 months after surgery, including: Auditory perceptual evaluation (GRBAS scale) Videostroboscopy Acoustic and aerodynamic voice analysis Vocal Fatigue Index (VFI) All participants will provide written consent and undergo standard preoperative assessments including medical history, ENT examination, laboratory tests, ECG, and anesthesia evaluation.
