Using the pulsed KTP (green light) laser, we can now treat certain types of vocal cord and laryngeal pathology in the clinic while the patient is under topical anesthesia.

This is a major surgical advance and avoids the risks, costs, and morbidity associated with general anesthesia. Another advantage of this technique is that it targets the blood supply while preserving the vibratory structure of the vocal cords.

Lesions that may be treated with this new modality include laryngeal papilloma, keratosis and precancerous lesions, granulomas, and other vascular  lesions. Because papilloma and precancerous lesions frequently recur, patients can now be treated less invasively and without repeated operative procedures requiring general anesthesia.
