The KTP laser (potassium titanyl phosphate) is a versatile, office-based laser used to treat a variety of voice, airway, and nasal conditions. It’s especially effective for treating vascular lesions like varices or papillomas, inflammatory growths like granulomas, and benign vocal fold lesions like nodules and polyps. It’s also used in the nasal cavity to stop bleeding (epistaxis) or reduce enlarged turbinates, which improves nasal breathing.

The procedure is usually done in the office using a flexible scope, with topical anesthesia to keep you comfortable. A thin laser fiber is threaded through the scope to deliver gentle pulses of light energy directly to the lesion. Most sessions take 20–30 minutes. You may feel heat, pressure, or the urge to cough briefly, but the discomfort is minimal for most patients. Some voice rest is usually recommended for 1–3 days, and mild hoarseness or sore throat can last up to a week. Conditions like papillomas or chronic lesions may require multiple sessions spaced weeks apart. The KTP laser is highly effective and precise, with a very low risk of scarring or tissue damage, and it allows for outpatient treatment without general anesthesia.
