“…There are similarities between vascular patterns of benign and malignant laryngeal lesions. The PVC with wide-angled turning points, as observed in laryngeal Papillomatosis can be difficult to distinguish from PVC with narrow-angled turning points, as observed in pre-malignant and malignant histopathologies [ 5 , 12 , 13 , 14 ]. Hence, the interpretation of vascular patterns in enhanced CE images requires an extensive learning curve from the clinicians to reduce the risk of subjective evaluation that can cause potential problems in differentiation between benign and malignant laryngeal lesions [ 4 , 10 , 12 , 15 , 16 ].…”

“…The first attempt to apply this dichotomic classification was in the study by Šifrer et al [29] who analyzed 80 vocal cords lesions in which the identification of a perpendicular vascular pattern was diagnostic for CIS-SCC with a sensitivity of 100%, specificity of 95%, PPV of 88%, and NPV of 100%. Further analysis evaluating a larger cohort of 288 vocal cords gave similar results (sensitivity 98%, specificity 95%, PPV 88%, and NPV 99%) [30].…”

“…Die Bildung neuer Gefäße (Neoangiogenese) ist eine der Grundvoraussetzungen [3]. Dieses diagnostische Potenzial der endoskopischen Detektion der PGV wurde in den letzten Jahren von unterschiedlichen Autoren bekräftigt [7,18,24,25]. Bei der WLE ist die genaue Betrachtung und Analyse solcher Gefäßmuster nur eingeschränkt möglich.…”

“…Wird NBI mit der KE kombiniert, also ein Kontaktendoskop direkt auf die Schleimhaut im NBI-Modus aufgesetzt, kann eine weitaus detailreichere Gefäßdarstellung gelingen. So kann die Differenzierung zwischen benignen und malignen Läsionen der Stimmlippen und die Früherkennung von höhergradigen Dysplasien und Larynxkarzinomen weiter verbessert werden [4,7,25]. Mittels NBI-KE erzeugte Aufnahmen von Gefäßveränderungen eignen sich sogar für eine automatisierte Auswertung mit Methoden des maschinellen Lernens und algorithmenbasierter Klassifizierungsszenarien [10].…”
