目的探讨经口入路至颅颈交界处的解剖结构。方法对36具身体标本进行经口入路手术。对暴露野周围的特殊解剖结构进行测量，优先考虑与椎动脉(VA)相关的测量。结果暴露野部分覆盖椎基底动脉系统融合部。经口入路可显露中斜坡至上C3椎体。颅神经和颈神经从椎基底动脉的尾部发出，绕前外侧走行，在椎基底动脉的颅内段可见异常。安全野呈倒梯形，其中最宽的点在C2横突水平距中线25.5 ± 4.5 mm，最窄的点在C2-3水平距中线11.2 ± 1.5 mm。结论VA是该入路安全野的标志，手术时应注意避免损伤VA和神经。
ObjectiveThe aim of this study was to demonstrate the anatomical structures of the transoral approach to the craniovertebral junction. We evaluated the necessary exposure field and the safety of this approach.MethodsSurgical operations with the transoral approach were performed on 36 cadaver specimens. The special anatomical structures were measured surrounding the exposure field with priorities given to measurements relating to the vertebral artery (VA). The anatomical relationships between the VA and nerves were observed.ResultsThe exposure field partly covered the vertebral basilar system confluent. The middle clivus to upper C3 vertebral body can be exposed by transoral approach. Cranial nerves and cervical nerves emerged from the caudal of vertebrobasilar artery and circumambulated anterolaterally, and some abnormalities were observed in the intracranial segment of vertebrobasilar artery. The safe field was in an inverted trapezoid shape, of which the widest point was 25.5 ± 4.5 mm to the midline at C1 transverse process level; the narrowest point was 11.2 ± 1.5 mm to the midline at the C2–3 level.ConclusionBecause the VA is the landmark of the safe field in this approach, surgeons should be very careful to avoid injuries of the VA and nerves while operating in the intracranial field or at the C2–3 level.
