本文介绍74例颞骨球瘤外科手术经验。指出近年来由于CT的采用和改进,以及面神经移位手术的开展促使球体瘤的手术有所进展。认为要使手术取得预期的疗效,必须对肿瘤进行精确的定位。作者将球体瘤分为以下四型:A型:肿瘤限于中耳腔。B型:限于鼓室、乳突区,但未破坏骨壁。C型:C_1肿瘤破坏颈静脉孔及颈静脉球,并累及颈动脉垂直部骨管;C_2肿瘤破坏颞骨迷路下部,并侵犯颈动脉垂直部骨管;C_3肿瘤累及迷路下和岩尖部以及颈动脉骨管的水平部。D型:D_1肿瘤侵及颅内,直径小于2cm,可经颞下窝一期手术切除;D_2肿瘤在颅内,直径大于2cm,需要耳科及神经外科二期手术;D_3肿瘤侵入颅内,已不能手术。作者对A、B型肿瘤采用鼓室 This article describes the surgical experience of 74 cases of fibula. It is pointed out that in recent years, the use of CT and its improvement, as well as the development of facial nerve displacement surgery, have led to advances in the surgery of spherical tumors. It is believed that the tumor must be accurately positioned to achieve the desired therapeutic effect. The authors divided the spherical tumor into the following four types: Type A: The tumor was limited to the middle ear cavity. Type B: limited to the tympanic area, mastoid area, but did not destroy the bone wall. Type C: C_1 tumor destroys the jugular foramen and jugular venous bulb, and involves the vertical part of the carotid artery; the C_2 tumor destroys the lower part of the zygomatic labyrinth and invades the vertical part of the carotid; the C_3 tumor involving the labyrinthine and petrous apex and neck The horizontal part of the arterial bone tube. Type D: D_1 tumor invasion and intracranial, diameter less than 2cm, can be removed through the first infratemporal fossa; D_2 tumor in the brain, diameter greater than 2cm, requiring ear and neurosurgery secondary surgery; D_3 tumor invasion of the brain, No surgery. The authors use a tympanum for type A and B tumors
