The advent of the endoscope has facilitated otological surgery in recent years. Advances in optical technology have led to the development of high definition visualisation, such as 4K magnification. Narrow band imaging (NBI) has been shown to improve visualisation of tissue based on varying degrees of vascularity. This is a feasibility study, the first of its kind, aiming to investigate the appearances of middle ear anatomy and pathology (tympanic membrane, tympanosclerosis, cholesteatoma, granulation, endolymphatic sac hydrops, otosclerosis) under the NBI filter, using a high definition 4K endoscope. Qualitative analysis of image detail and operating time in minutes were recorded. The study demonstrates that these two technologies can be implemented with ease into practice, and show a clear differentiation between pathology and normal anatomy. NBI and 4K magnification prove to be useful adjuncts to the surgeon during endoscopic ear surgery.
近年来，内窥镜的出现推动了耳科手术的发展。光学技术的进步带来了高清可视化的发展，如4K放大倍率。窄带成像（NBI）已被证明可根据不同程度的血管化改善组织可视化。这是一项同类研究中的首例可行性研究，旨在使用高清4K内窥镜研究在NBI滤光片下中耳解剖结构和病理情况（鼓膜、鼓室硬化、胆脂瘤、肉芽、内淋巴囊积水、耳硬化症）的表现。记录了图像细节的定性分析和以分钟为单位的手术时间。该研究表明，这两种技术可以轻松应用于实践，并能清晰区分病理情况和正常解剖结构。NBI和4K放大倍率被证明是内窥镜耳科手术中外科医生的有用辅助工具。
