颈静脉孔处的肿瘤常以亚铃状向颅内外生长,因周围复杂结构的限制,使手术路径狭窄,操作困难。作者将耳蜗与颞下径路相结台,称为“扩大的经耳蜗径路”,可完整地切除该处的肿瘤。手术方法:绕耳周作“Y”形切口,下部切口沿胸锁乳突肌前缘止于环状软骨。切断外耳道骨与软骨连接部,分离皮瓣并使头皮瓣返折,暴露乳突、颞鳞、骨性外耳道、颧弓及颞 The jugular foramen often grows intracranially and intracranially in the form of sub-bellies. Due to the complexity of surrounding structures, the surgical path is narrow and the operation is difficult. The authors associate the cochlea with the infratemporal approach, known as the “expanded cochlear approach,” to completely excise the tumor there. Surgical methods: around the ear for “Y” shaped incision, the lower incision along the leading edge of the sternocleidomastoid ring in the annular cartilage. Cut off the external auditory canal and cartilaginous junction, the flap is separated and the scalp flap is folded back, exposing mastoid, temporal scales, bony external auditory meatus, zygomatic arch and temporal
