作者自1966年首次于鼻科应用手术显微镜。检查前先除净鼻腔内分泌物。为窥及整个视野,先用最小放大倍数(4～6倍),以后可用更大倍数(10倍或更多)。在镜下可以窥视鼻腔侧壁、鼻窦开口、嗅裂及小的息肉;可以早期发现较小肿瘤及肿瘤复发;能清楚窥及肿瘤的血管网及组织改变:白色或灰色小岛、扩张的血管、纤维膜及突起等等。作者进行了改善和保持嗅觉的鼻内显微手术 The author has applied surgical microscopy to the nose for the first time since 1966. Except the net nasal secretions before inspection. To see the entire field of view, first use the smallest magnification (4 ~ 6 times), then use a larger multiple (10 times or more). In the microscope can peep nasal wall, sinus openings, sniffing and small polyps; early detection of small tumors and tumor recurrence; can clearly see the tumor vascular network and tissue changes: white or gray island, the expansion of blood vessels , Fiber membrane and protrusions and so on. The authors conducted intranasal microsurgery to improve and maintain the sense of smell
