结果：大鼠面神经出茎乳孔后可分为两段。
Results: The extracranial section of rat facial nerve was divided into 2 segments.
在50个完整颅骨（100例）上观测茎乳孔及其邻近结构。
Stylomastoid foramen and its adjacent structures were observed and measured on 50 intact skulls(100 sides).
面神经由茎乳孔出颅后，经腮腺、咬肌和颊区三段分布于面肌。
Facial nerve was divided into three segments (parotid gland, masseter and cheek) after leaving skull from stylomastoid foramen.
结果：面神经阻滞进针的深度：乳突尖至茎乳孔的距离，男性左侧为16。
Result: The needle inserted depths from mastoid into stylomastoid foramen for males and females were 16.
从茎乳孔发出向后侧面生长到下颌后静脉并穿过腮腺的生长方式有助于局限性神经鞘瘤与其他腮腺肿瘤鉴别。
Growth from the stylomastoid foramen running posterolaterally to the retromandibular vein coursing through the parotid gland can help distinguish a facial nerve schwannoma from other parotid tumors.
头侧直肌起始于tpa的上表面，止于枕骨颈静脉突的下表面，可作为确定颅外颈静脉孔、茎乳孔的解剖标志。
