Introduction Narrow-band imaging is an endoscopic diagnostic tool that, focusing on superficial vascular changes, is useful to detect suspicious laryngeal lesions, enabling their complete excision with safe and tailored resection margins. Objectives To analyze the applications and benefits of narrow-band imaging in detecting premalignant and malignant laryngeal lesions through a comparison with white-light endoscopy. Data Synthesis A literature search was performed in the PubMed, Scopus and Web of Science databases using strict keywords. Then, two authors independently analyzed the articles, read the titles and abstracts, and read completely only the relevant studies according to certain eligibility criteria. In total, 14 articles have been included in the present review; the sensitivity, specificity, positive and negative predictive values, and accuracy of pre- and/or intraoperative narrow-band imaging were analyzed. The analysis showed that narrow-band imaging is better than white-light endoscopy in terms of sensitivity, specificity, positive and negative predictive values, and accuracy regarding the ability to identify cancer and/or precancerous laryngeal lesions. Moreover, the intraoperative performance of narrow-band imaging resulted more effective than the in-office performance. Conclusion Narrow-band imaging is an effective diagnostic tool to detect premalignant and malignant laryngeal lesions and to define proper resection margins. Moreover, narrow-band imaging is useful in cases of leukoplakia that may cover a possible malignant lesion and that cannot be easily assessed with white-light endoscopy. Finally, a shared, simple and practical classification of laryngeal lesions, such as that of the European Laryngological Society, is required to identify a shared lesion management strategy. Key Points Narrow-band imaging is useful in detecting suspicious laryngeal lesions and proper resection margins showing intraepithelial papillary capillary loops (IPCLs) that are considered a main cancer feature.Narrow-band imaging is used both pre- and intraoperatively, but it provides more precise information if used during surgery.Compared with white-light endoscopy, narrow-band imaging enables a better assessment of the lesions covered by a thick white plaque (such as in cases of leukoplakia)The classification of the European Laryngological Society is the simplest and the most practical for the identification of various laryngeal lesions compared with other classifications.
Fulltext Impact of Narrow Band Imaging in Pre-Operative Assessment of Suspicious Oral Cavity Lesions: A Systematic Review

Iran J Otorhinolaryngol, 2021 May;33(116):127-135.

Introduction: Narrow band imaging (NBI) is a powerful tool that allows visualizing the mucosal and submucosal vasculature. Among the available diagnostic techniques, NBI is one of the most valid for early detection of oral squamous cell carcinoma (OSCC).
Materials and Methods: We carried out a bibliographic search in PubMed, Scopus and Web of Science databases using relevant keywords. Articles selected were screened by two independent authors based on inclusion and exclusion criteria. Nine papers were singled out according to the eligibility criteria and included in this review. We investigated the articles for pooled sensitivity, specificity, accuracy, positive predictive value and negative predictive value of pre-operative NBI.
Results: The use of NBI examination in the oral cavity revealed higher specificity, sensitivity, positive and negative predictive values and accuracy compared to white light examination for the diagnosis of oral squamous cell cancer (OSCC). In addition, NBI has proved great utility in detecting malignancy features in oral pre-malignant lesions.
Conclusions: This review shows that NBI is a powerful tool for examining oral suspicious lesions. Most of the articles examined revealed high values of sensitivity, specificity, positive predictive value, negative predictive value and accuracy in detection of oral malignant and pre-malignant lesions. Therefore, the use of NBI is highly recommended for the early detection of oral cancer and potentially malignant disorders. Future studies should seek to affirm the validity of NBI and in particular to standardize NBI classification.
