KTP (potassium titanyl phosphate) laser ablation treats vascular lesions, papillomas (caused by HPV), or certain benign and malignant vocal fold growths. The KTP laser is unique because it targets blood vessels, allowing for precise treatment of lesions with minimal damage to the surrounding tissue — making it an excellent tool for preserving vocal quality.

During the procedure, the patient is placed under general anesthesia, and a laryngoscope is used to expose the vocal folds. The surgeon then uses the KTP laser, delivered through a thin fiber, to gently shrink or remove the lesion. Because it causes less thermal damage than other lasers, healing is typically quicker, and voice outcomes are often excellent. Patients usually need voice rest for a few days afterward, followed by a gradual return to speaking. In some cases, especially with papillomas, multiple treatments may be necessary. Follow-up may include repeat scopes and voice therapy.
