A new method of laryngeal laser surgery under local anesthesia was developed for the treatment of benign mass lesions using KTP laser. Thirteen patients have underwent this surgery since August 1995 to April 1996. Lesions involved were leukoplakia in five patients, granuloma in four, hemangioma in one, and papilloma in three. Ten cases underwent this laser surgery once and have demonstrated no evidence of recurrence. One case of granuloma showed recurrence repeatedly, and needed this laser surgery three times. One case of papilloma showed widespread lesion, and we could not remove the tumor by this procedure and required laryngomicrosurgery. A recurrent small lesion which occurs after laryngomicrosurgery could be well controlled by the present laser surgery under local anesthesia. Another case of widespread papilloma displayed remnant lesion after this surgery and dropped out. No case had a postoperative hemorrhage and edema of larynx. This method has proved to be useful for treating benign laryngeal mass lesions easily and repeatedly under local anesthesia on an outpatient basis.
