摘要
目的 :分析鼻窦CT表现并探讨对内窥镜手术的指导价值。方法 :收集分析经手术病理证实的 5 6例鼻窦炎的术前CT片并分析其CT表现。结果 :①术前CT片可确定病变的程度和范围 ;②中鼻道及鼻窦解剖变异 :中鼻甲气化 11例 ,中鼻甲偏曲 2 1例 ,钩突异常 3例 ,Haller气房 9例 ;③筛窦和蝶窦毗邻解剖变异 :纸板缺如或破坏 3例 ,视神经管突入后组筛窦 1例 ,双侧颈内动脉与蝶窦毗邻 4例。结论 :鼻窦CT扫描对功能性鼻内窥镜手术有肯定指导价值 。
Objective:The directing value were explored for functional endoscopic sinus surgery according to the results of CT.Methods:Fifity six cases of surgically proven sinusitis were selected,analyzed the appearance of CT.Results:①CT imaging of paranasal sinuses could show the extent and degree of the lesion;②Anatomic variants of midnose trunk and sinuses:middle turbinate aerificatuion(11 cases),middle turbinate deflexion(21 cases),uncinate process abnormity(3 cases),Haller pore(9 cases);③Anatomic variants of relationships of ethmoid sinus and sphenoid sinus:lamina papyracea lack or destroy(3 cases),optic nerve in burst(l case),bilateral arteria carotis interna adjacent with sphenoid sinus(4 cases).Conclusion:CT,by providing significant informations which are helpful in directing functional endoscopic sinus surgery is an indispensable imaging examinaion,prior to operation.
