Abstract
A 38-year-old man visited the hospital for a voice change that began two months previously. There were no other accompanying symptoms; the patient had a history of 20 years of smoking. Carbon dioxide (CO2) laser cordectomy was performed on the left side of the vocal cord, and the biopsy results showed squamous cell carcinoma. Radiation therapy was not performed, and CO2 laser cordectomy was performed again because of a recurrence of left vocal cord mass three years after a progress observation.
