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.
