摘要
目的显示口腔颌面部复发性肿瘤侵犯中颅底的ＣＴ表现。方法３７例口腔颌面部复发性肿瘤患者被行以横轴面和冠状面（２６例）ＣＴ检查，所有病变均经病理检查证实。结果ＣＴ上显示的中颅底破坏方式有四种：（１）颅底骨外板吸收（５例）；（２）颅底骨内外板均吸收（２４例）；（３）卵圆孔扩大（３例）；（４）颅底骨硬化和吸收并存（５例）。复发性肿瘤破坏中颅底最多的结构是蝶骨大翼（３６例）。ＣＴ显示病变侵入颅内者共２４例，受累的颅内结构有海绵窦（１６侧），大脑颞叶（１５侧）和脑垂体（１例）。结论ＣＴ上显示的颅内侵犯与上述中颅底破坏方式密切相关。ＣＴ检查有助于临床上评价颌面复发性肿瘤侵犯中颅底。
Objective To
domonstrate the CT manifestations of the recurrent oral maxillofacial tumors invading the
middle skull base. Methods CT detections with axial (37 cases) and coronal (26 cases) scans
were performed in thirtyseven patients who suffered from the recurrent oral maxillofacial
tumors.All lesions were proven histopathologically. Results Four patterns of the central skull
base erosion showing on CT images were encompassed:1.resorption of the outer cortical
margin (5 cases);2.resorption of both outer and inner cortical laminae (24 cases);3.enlargement
of the ovale foramen (3 cases);4.combined of sclerosis and resorption of the skull base (5
cases).The sphenoid greater wing involvement by the recurrent lesions was more frequently
seen in our series (36 cases).Twentyfour patients with the recurrent lesions were identified as
following intracranial structures affected:the cavernous sinus (n=16),temporal lobe (n=15),and
pituetary (n=1). Conclusion It is believed that involvement of the intracranial structures is in
close relationship with the aforementioned erosive patterns of the central skull base.The role of
CT examination for evaluating the oral maxillofacial recurrent lesions invading the central skull
base is very important.
