title: [Observation on nasal mucociliary ultrastructure of ostiomeatal complex].
abstract: Functional endoscopic sinus surgery (FESS) was performed on 35 patients who suffered. from chronic nasosinusitis. All patients recovered six months after operation. During FESS, 10 specimens of pathological mucosa were obtained near the ostium of maxillary sinus. Scanning electron microscope and transmission electron microscope were used to observe pathological changes of mucociliary ultrastructure. The results indicate that FESS is easier, safer and more practicable surgery than traditional one. The pathological changes observed include loss of cilia, disorientation, short cilia and tubular abnormalities. These ultrastructural changes are believed to be the results of long-term inflammation in the nose and paranasal sinuses.
