目的：目的：观察泪阜与下睑缩肌的关系，探讨泪阜与下睑缘的关系。研究方法：采用经泪阜入路对14例眼眶内侧减压术（7例）和10例眼眶内侧壁骨折复位术（10例）的泪阜移位方向进行了研究。本文报告了40例正常人80个泪阜与下睑牵开肌的关系及其与下睑缘的关系。在4例（2例）惰性T手术中，直接调查下眼睑牵开器是否延续到泪阜。结果：所有泪阜均向下方移位。志愿者的泪阜位于下眼睑牵开器附近，呈卵形，并以下外侧方向倾斜定位。在正常眼睑位置，泪阜的上级边界与下眼睑边缘对齐。在惰性T程序中，下眼睑牵开器显示出与泪阜直接连接。结论：泪阜与下睑牵开肌直接相连，下睑牵开肌在泪阜的运动中与内眦睑直肌筋膜起对抗作用，泪阜位置倾斜，指向下外侧，其上级缘与下睑缘平齐。
Purpose: To examine the relationship between the lacrimal caruncle and the lower eyelid retractors and to study the shape and position of the lacrimal caruncle in relation to the lower eyelid margin. Methods: A transcaruncular approach was used to investigate the direction of the lacrimal caruncle shift in 14 medial orbital decompressions (7 patients) and 10 medial orbital wall fracture reductions (10 patients). Eighty lacrimal caruncles in 40 normal volunteers were examined regarding the position of this structure in relation to the lower eyelid retractors and its shape in connection to the lower eyelid margin. Direct investigation of whether the lower eyelid retractors continued to the lacrimal caruncle was performed during 4 lazy-T procedures (2 patients). Results: All the severed lacrimal caruncles moved inferolaterally. The volunteers' lacrimal caruncles were situated adjacent to the lower eyelid retractors, had an ovoid shape, and were positioned obliquely with an inferolateral direction. In the normal eyelid position, the superior border of the lacrimal caruncle was aligned with the lower eyelid margin. During the lazy-T procedures, the lower eyelid retractors were shown to have direct connection to the lacrimal caruncle. Conclusion: The lacrimal caruncle has a direct connection to the lower eyelid retractors that plays an antagonistic role to the medial rectus caspulopalpebral fascia in the movement of the lacrimal caruncle, and it is positioned obliquely, directing inferolaterally with its superior border in level with the lower eyelid margin.
