Abstract

The optimal treatments of carcinoma in situ of glottis include radiotherapy, laser surgery and vertical partial laryngectomy. Conventional surgical treatments need general anesthesia and radiotherapy has several complications. Recently, the effectiveness of 532 nm potassium titanyl phosphate (KTP) laser has been proven and widely used in vocal fold diseases even some cases of vocal fold dysplasia. A patient with difficult laryngeal exposure underwent fiberoptic laryngeal laser surgery using KTP laser under local anesthesia, showed improved voice outcome and the glottic lesion was removed successfully without local recurrence and regional metastasis 18 months after surgery.
