A Intraoperative endoscopy by WL-HDTV 70° telescope shows a leuco-erythroplakia of the anterior and middle thirds of the right vocal cord.

B Intraoperative endoscopy by NBI-HDTV 70° telescope shows the typical neoangiognetic pattern (brownish spotted areas) in the posterior third of the vocal cord then confirmed at histopatologic examination to be carcinoma in situ.

A Follow-up examination by flexible WL endoscopy after extended cordectomy shows a leucoplakia surrounded by normal mucosa.

B The same view by NBI shows the typical vascular pattern suspicious for neoplasia involving even the entire floor of the anterior third of the ventricle. The histology resulted to be carcinoma in situ.

A Intraoperative examination by 0° rigid WL-HDTV telescope shows a sessile lesion of the anterior portion of the right vocal cord;

B The same picture by NBI-HDTV shows the typical neoplastic vascular pattern and gives a better definition of the surgical margins. The histology confirmed to be an invasive carcinoma reaching the lateral aspect of resection.

A Rigid preoperative endoscopy shows a leuco-erithroplakia of the right margin of the mobile tongue in a patient with oral cavity lichen planus;

B Same view by NBI-HDTV shows better definition of the lesion’s margins and the typical vascular pattern surrounding the entire leucoplakia. The histological examination confirmed the lesion to be a moderate dysplasia.

A Rigid intraoperative endoscopy by WL-HDTV shows an erythroplakia of the left margin of the mobile tongue previously biopsied and defined as chronic inflammatory lesion;

B Same view by NBI-HDTV shows better definition of the lesion’s margins and the typical vascular pattern. The histology resulted to be adeno-squamous carcinoma.

A WL preoperative view of a squamous cell carcinoma of the uvula;

B Flexible preoperative endoscopy shows also an erythroplakia of the posterior right oral floor;

C Same view by NBI with better definition of the lesion and its vascular pattern. The histology confirmed the lesion to be a synchronous squamous cell carcinoma.

A Rigid intraoperative endoscopy by WL-HDTV shows a leucoerythroplakia of the left soft palate;

B+C Same view by NBI-HDTV shows better definition of the lesion’s margins and the typical vascular pattern. The

histology resulted to be carcinoma in situ.

A Flexible preoperative videoendoscopy (up) and intraoperative view by 120° rigid telescope (down) by WL-HDTV of erythroplakia involving the left vocal cord.

B Same view by NBI-HDTV shows better definition of lesion’s margins and the typical vascular pattern. The histological examination confirmed the lesion to be carcinoma in situ.

A Intraoperative examination by rigid WL-HDTV 0° telescope after resection of squamous cell carcinoma of the right piriform sinus shows an erythroplakia of its lateral wall (up), with further magnification (down);

B The same pictures by NBI-HDTV show the typical vascular pattern suspicious for persistence of disease confirmed by histology to be microinvasive carcinoma.

A Rigid intraoperative endoscopy shows a lesion suspicious for granuloma of the left margin of the mobile tongue after multiple resection for oral cavity squamous cell carcinoma;

B Same view by NBI-HDTV with evidence of the typical vascular pattern suspicious for recurrent disease confirmed by histology as microinvasive carcinoma.
