钩突组织学与影像学观察

为了对钩突有更深入的认识，在电镜下观察了１５个钩突粘膜的组织结构和３２例患者的鼻部冠状位ＣＴ图像。结果：①在病理情况下，钩突粘膜的结构紊乱，鼻窦炎症越重，钩突粘膜损伤越严重；②钩突有内移、外移、气化、肥大等解剖变异和病理改变。结论：窦口鼻道复合体解剖变异与慢性鼻窦炎／鼻息肉的形成关系密切；对鼻窦炎患者切除钩突，开放筛漏斗有利于改善鼻窦的通气引流；手术前和手术中认真阅读ＣＴ片有助于设计手术方案，防止

The uncinate process: ultrastructural and CT studies]

To provide further understanding of uncinate process, 15 uncinate processes were examined under scanning electron microscope, and 32 high-resolution coronal CT scans were studied in patients with septal deformity or sinusitis. It was found that(1)pathological ultrastructural changes of uncinate process were noted in patients with chronic sinusitis; (2) medially deviated, laterally deviated, pneumatization and hypertrophy of uncinate process were demonstrated. The following conclutions were drawn(1)the anatomic variations in ostiomeatal complex is responsible for the formation of chronic sinusitis; (2)for patients with chronic sinusitis, uncinatectomy is the treatment of choice; (3)preoperative and intraoperative studies of CT scans are mandatory for avoidance of complications.
