颞骨和颅底的血管球瘤,其大小可由局限于鼓岬的极小肿瘤,至大区域破坏、侵及神经的大肿痛近年来,根据Glasscock-Jckson分类法,将血管球瘤分为鼓室型和颈静脉型两大类。按其扩展范围。鼓室型血管球瘤又分为:①局限于鼓岬的小肿瘤;②肿瘤充满中耳腔;③除中耳腔外,扩展至乳突;④肿瘤充满中耳腔,扩展至乳突或穿过鼓膜入外耳道,也可侵及颈动脉前区。颈静脉血管球瘤可分为:①累及颈静脉球、中耳和乳突的小肿瘤;②肿瘤扩展至内耳道下方,可向颅内扩展;③肿瘤侵至岩尖,可出现颅内侵犯;④肿瘤超出岩尖进入蝶骨斜坡或颞下窝,可有颅内侵犯。此分类目的不仅为临床分型用,也是术前了解病变范围所需。血管球瘤的诊断:血管球瘤起病呈隐袭性,
Vascular tumors of the sacrum and base of the skull, whose size can be limited to very small tumours of the tympanum, to a large area of destruction, invasion and swelling of the nerves in recent years. According to the Glasscock-Jckson classification, the glomus tumors are divided into tympanum Type and jugular vein two categories. According to its scope of expansion. Tympanic glomus tumors are further divided into: 1 small tumours limited to drumsticks; 2 tumours filling the middle ear cavity; 3 extending beyond the middle ear cavity to the mastoid; 4 tumours filling the middle ear cavity, extending to mastoid or wearing Through the tympanic membrane into the external auditory canal, it can also invade the anterior area of the carotid artery. Jugular venous glomus tumors can be divided into: 1 small tumors involving the jugular bulb, middle ear, and mastoid; 2 tumors extending below the inner ear canal, can be extended to the brain; 3 tumor invading to the tip of the rock, there may be intracranial invasion 4 tumors beyond the tip of the rock into the sphenoid slope or infratemporal fossa, may have intracranial violations. The purpose of this classification is not only for clinical classification, but also for preoperative understanding of the extent of the lesion. Diagnosis of glomus tumors: Invasion of glomus tumors is insidious.
