Application of narrow-band imaging in the detection of laryngeal papilloma

Abstract

Abstract:

Objective:To explore the efficacy of narrow band imaging (NBI) for diagnosing laryngeal papilloma (LP) detection.Methods:From February 2018 to September 2021, a total of 59 patients with pathologically confirmed LP were enrolled in this study. The detection rate and missed detection rate of LP by NBI were calculated and were compared with those by white light endoscopy.Results:There were 34 cases with single lesion (signal group) and 25 cases with multiple lesions (multiple group). The detection rate of LP by NBI was higher than that by white light pattern (84vs61, 85.71%vs62.24%,P<0.01). The detection rate of LP by NBI was higher than that by white light pattern (30vs23, 88.24%vs67.65%,P<0.05) in single group as well as in the multiple groups (54vs38, 84.38%vs59.38%,P<0.01). By NBI pattern, the number of missed lesions with diameter ≤3 mm was 12, and the number of missed lesions with diameter>3 mm was 2. By white mode, the number of missed lesions with diameter ≤3 mm was 13, and the number of missed lesions with diameter>3 mm was 24. There was significant difference in missed lesions with diameter >3 mm between the two modes (P<0.01). The missed lesions by NBI were located in the laryngeal surface of epiglottis (57.14%) and the anterior vocal cord (42.86%), while by white light pattern were mainly located in the laryngeal surface of epiglottis (54.05%) and the anterior vocal cord (32.43%).Conclusions:The detection rate of LP by electronic laryngoscope NBI pattern is higher than that by white light pattern. It indicates that NBI has advantage in detecting multi LP lesions over white light pattern.
