目的研究茎突毗邻关系，为咽旁颞下区手术提供外科解剖基础。方法测量颅骨。结果茎实根部深面有颈静脉孔，两者相距约3mm。颈静脉孔前有动脉管外口，分隔两者间的骨板下缘厚约1．87mm。在颈动脉管外口前外方有蝶骨角棘，二者相距约6．5mm。角棘之外侧有颞下颌关节窝，之前方为棘孔。棘孔之前内侧有卵圆孔。结论茎突可作为咽旁颞下区的外科解剖钥匙。
Objective To study the relationship between the styloid process and provide the surgical anatomy for the operation in the parapharyngeal area. The method measures the skull. Results There was a jugular foramen deep in the roots of the stem, which was approximately 3 mm apart. The jugular foramen had an external arterial orifice, and the lower edge of the bone plate separating the two was about 1.87 mm thick. There was sphenoid horn spine outside the carotid artery, which was about 6.5mm apart. The temporomandibular joint fossa is located on the outside of the corner spine, and the front side is a spinous hole. There is an oval hole inside the spinous hole. Conclusion The styloid process can be used as the key to surgical anatomy of the parapharyngeal infratemporal area.
