Abstract
Microvasucular lesions of the vocal fold mucosa arise from chronic physical irritation in patients who make excessive use of their voice. These lesions are disrupted by mucosal vibration, which thus causes hemorrhagic polyps. These lesions are treated by either stripping or vaporization using a CO, laser. The stripping method is recommended in comparison to the CO, laser because it decreases mucosal vibration and scar formation and more severe complications, such as heat injury, and depth invasion. The KTP laser uses a wavelength that is absorbed by hemoglobin. A previous case report described the successful treatment of microvasucular lesions of the vocal mucosa using the KTP laser. The present paper reports that the KTP laser surgery was applied to five patients with microvasucular lesions accompanied with polyps. In all of these cases, the postoperative phonatory functions and the mucosal vibration were found to significantly improve.
