Early diagnosis of malignant tumors in the head and neck region is very difficult. Therefore, endoscopic systems with narrow band imaging (NBI), which enhances image contrast, have an important clinical value in detecting superficial mucosal lesions. In particular, highlighting of the intraepithelial microvasculature helps determine the nature of the lesion. This new image-enhanced technology already has proven effective in the early diagnosis of head and neck squamous cell carcinoma, including laryngeal, hypopharyngeal, oropharyngeal, nasopharyngeal, and oral cancers, as well as of unknown primary cervical lymph node metastasis. NBI laryngoscopy can be applied easily in clinical practice and has become a valuable tool in diagnosing head and neck cancers early, providing the option of minimally invasive treatment such as endoscopic or partial surgical resection.
头颈部恶性肿瘤的早期诊断非常困难。因此，具有窄带成像（NBI）功能的内镜系统可增强图像对比度，在检测浅表黏膜病变方面具有重要的临床价值。特别是，上皮内微血管的突出显示有助于确定病变的性质。这种新的图像增强技术已被证明在头颈部鳞状细胞癌的早期诊断中有效，包括喉癌、下咽癌、口咽癌、鼻咽癌和口腔癌，以及不明原发灶的颈部淋巴结转移癌。NBI喉镜检查在临床实践中易于应用，已成为早期诊断头颈部癌症的宝贵工具，为内镜或部分手术切除等微创治疗提供了选择。
