Impact of Narrow Band Imaging in Pre-Operative Assessment of Suspicious Oral Cavity Lesions: A Systematic Review

Carmelo Saraniti et al. Iran J Otorhinolaryngol. 2021 May.

Abstract

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.
