5 CONCLUSION
Vascular changes may play an important role as one of the most prominent features in endoscopic work-up of laryngeal lesions. Further validation of our preliminary findings, especially in combination with further standardized morphologic endoscopy findings (together with macroscopic appearance, mucosal vibration, vocal cord stiffness and others) should be undertaken to increase reliability of pre- and intraoperative diagnosis of leukoplakia and malignant glottic lesions.
