New surgical techniques have extended the head and neck surgeon's domain to include various skull-base lesions. The infralabyrinthine approach incorporates these techniques and can be used to resect benign and malignant tumors involving the base of the temporal bone. Lesions of the internal carotid artery near the carotid foramen are also readily accessible. The main surgical steps in the infralabyrinthine approach include (1) mastoidectomy, (2) anterior transposition of the facial nerve, (3) neck dissection, (4) removal of the lateral tympanic bone, (5) exposure of the jugular foramen, and (6) exposure of the intratemporal carotid artery. Details of the infralabyrinthine approach are illustrated by photographs of surgical and cadaver dissections. Examples of various lesions successfully treated by this technique are presented. The important surgical anatomy of the infralabyrinthine compartment of the skull base is reviewed, with particular attention paid to the internal carotid artery, which, like the facial nerve, demands an intimate familiarity on the part of the temporal bone surgeon.
新的外科技术扩大了头颈外科医生的领域，使其包括各种颅底病变。迷路下入路融合了这些技术，可用于切除累及颞骨底部的良性和恶性肿瘤。靠近颈动脉孔的颈内动脉病变也易于处理。迷路下入路的主要手术步骤包括：（1）乳突切除术；（2）面神经前移；（3）颈部清扫术；（4）切除鼓室外侧骨；（5）暴露颈静脉孔；（6）暴露颞骨内颈动脉。外科手术和尸体解剖照片展示了迷路下入路的细节。本文还介绍了通过该技术成功治疗的各种病变实例。文中回顾了颅底迷路下间隙的重要手术解剖结构，尤其关注颈内动脉，与面神经一样，颞骨外科医生需要对其有深入了解。
