Narrow Band Imaging

2015

Objectives: Narrow band imaging (NBI) is supposed to be a technique for a better visualization of vessel structures in superficial tissue as it selects the wavelengths of hemoglobin. It was hypothesized that, in the regular follow-up examination of patients with recurrent laryngeal papillomatosis, NBI enables a better detection of laryngeal papillomatosis in contrast to normal white light endoscopy. Methods: Eleven patients, 10 with a known recurrent papillomatosis (8 with a relapse, 2 without) and 1 with a primary diagnosis of papillomatosis, were examined with normal white light and NBI endoscopy. Twenty-six video sequences (11 white, 11 NBI, 4 doubled for validity) were generated and ran…

Distribution and density of CD1a+ and CD83+ dendritic cells in HPV-associated laryngeal papillomas.

2009

Summary Background Respiratory papillomatosis associated with human papilloma virus (HPV) infection is the most common benign laryngeal neoplasm. The age of patients at disease onset, HPV type, number of surgeries are well known prognostic factors of the disease course. The correlation between dendritic cell (DC) density in tumor tissue and clinical prognosis was established. Aim The aim of our study was to estimate the density of DC in laryngeal papillomas associated with HPV types 6/11 infection and to evaluate the relationship between the number of DC and the disease severity. Materials and methods Our study included 40 randomly selected biopsy specimens from patients with HPV-positive l…

NBI and Laryngeal Papillomatosis: A Diagnostic Challenge: A Systematic Review.

2022

Narrow-band imaging (NBI) represents a valid aid in laryngeal squamous cell carcinoma (LSCC) diagnosis for detecting vascular changes. However, LSCC and laryngeal papillomatosis (LP) show similar vascular patterns that may lead to misdiagnosis and improper treatment. This review aims to deepen this NBI limit in order to stress a careful preoperative evaluation of laryngeal lesions. The research was carried out on PubMed, Web of Science and Scopus databases using specific keywords. The topic of research was assessed by these parameters: accuracy, sensitivity, specificity, and positive and negative predictive values. This review included only five articles: they demonstrated that NBI is bette…
