自1901年Hirschmann首次尝试鼻及鼻窦的内窥镜检查以来,随着内窥镜的改进,此法乃逐步应用于临床;尤其是推广应用可变换视角的新式鼻-鼻窦内窥镜以后,完全革新了鼻及鼻窦的传统检查方法,对临床诊断大有裨益。然而,鼻-鼻窦内窥镜在鼻科的应用中最有实际价值之处,乃在于治疗,尤其是手术方面的应用。鼻-鼻窦内窥镜手术的优点在于经一狭小进路即可手术,损伤轻微,而且在术中可选用不同视角的内窥镜,进行直向(0°)、偏向(30°)、斜向(70°)、侧向(90°)和逆向(120°)观察,影像放大而清晰,可在直视下准确可靠地施行深部的手术操作。其缺点在于镜管远端易
Since the first attempt of endoscopic examination of nose and sinuses by Hirschmann in 1901, this method has gradually been applied clinically with the improvement of the endoscope; especially after the introduction of a novel nasal-sinus endoscope with variable viewing angles Innovative nasal and sinus traditional inspection methods, the clinical diagnosis of great benefit. However, the most practical value of nasal sinus surgery in the application of rhinology lies in the treatment, especially the application of surgery. The advantage of nasal sinus surgery is that it can be operated with a small approach, with slight damage. In the endoscopic surgery, endoscopes with different angles of view can be used for direct (0 °), partial (30 °), oblique Viewing at (70 °), lateral (90 °) and reverse (120 °), the image is enlarged and clear, allowing deep and accurate surgical operation under direct vision. The disadvantage is that the distal end of the tube is easy
