The ultrastructures of the uncinate processes (UP) obtainel from 16 patients with clinical diagnosis of chronic sinusitis were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results showed that there were three main surface cell types on the UP: Most of the cilia was leaned, fractured and in disorder; Gaps of the cells increased obviously; Squamous cell metaplasia was seen; The endoplasmic reticulums and mitochondria in cytoplasm were expanded moderatly or seriously. The morphological changes indicated that mucus transportation functions in the anterior ethmoid region and the middle meatus were damaged. It is of great importance in occurrence and development of chronic sinusitis. The demaged nasal mucosa epithlial cells are repairable and reproducible.
通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）观察了16例临床诊断为慢性鼻窦炎患者的钩突（UP）超微结构。结果显示，UP上存在三种主要的表面细胞类型：大多数纤毛倾斜、断裂且排列紊乱；细胞间隙明显增大；可见鳞状上皮化生；细胞质中的内质网和线粒体有中度或重度扩张。形态学变化表明筛窦前部区域和中鼻道的黏液运输功能受损。这在慢性鼻窦炎的发生和发展中具有重要意义。受损的鼻黏膜上皮细胞是可修复和再生的。
