Abstract: OBJECTIVE To study the application of narrow-band imaging in diagnosis of the nasopharyngeal malignant lesions. METHODS A total of 52 cases of nasopharyngeal malignant lesions were examined and diagnosed by white and NBI endoscopy between June 2014 and August 2015, and their diagnosis efficacies were evaluated based on pathological diagnosis as a gold standard. RESULTS Of 52 cases, 46 cases were malignant lesion(88.46%) and 6 were non malignant lesion(11.54%). The diagnostic accuracy by NBI for the nasopharyngeal malignant lesions was 86.54%(45/52), which was significantly higher than that of white light 69.23%(36/52, χ2=4.522, P<0.05). The sensitivity of NBI and white light to detect nasopharyngeal carcinoma was 97.83%(45/46) and 78.26%(36/46) respectively(χ2=8.364, P<0.05). CONCLUSION NBI has high application value in diagnosis of nasopharyngeal carcinoma, and is expected to become one of the important means to diagnosis of the nasopharyngeal carcinoma.
