The maxillary artery can be injured during procedures in the subcondylar portion of the mandible. Thorough knowledge of this region is mandatory to avoid accidental puncture of the maxillary artery, which can lead to profuse bleeding that is hard to control.
In 16 halves of eight embalmed cadaver heads, the maxillary artery was dissected from the branching point to the entrance point to the maxillary sinus. Its anatomical relationships with certain landmarks were recorded numerically.
The mean distance of the branching point of the maxillary artery to the tragal pointer was 16.2 mm (range, 14.97 to 16.80 mm) in the horizontal plane and 21.4 mm (range, 19.14 to 23.53 mm) in the vertical plane. The mean vertical distance of the branching point to the Frankfort horizontal plane was 25.7 mm (range, 24.86 to 27.47 mm). The mean distance of the branching point of the maxillary artery to the tip of the condyle was 22.4 mm (range, 21.66 to 23.99 mm). The mean distance of the artery to the medial border of the subcondylar portion of the mandible was 6.8 mm (range, 4.06 to 8.47 mm). The mean distance between the deepest point of the sigmoid notch and the junction of the maxillary artery and sigmoid notch was 5.1 mm (range, 4.97 to 5.95 mm). The mean distance of the maxillary artery-sigmoid notch junction to the tragal pointer was 22.9 mm (range, 20.95 to 25.05 mm).
The maxillary artery can be injured during surgical procedures performed in the temporomandibular region. Its relationship with the subcondylar portion of the mandible varies.
在下颌骨髁突部手术过程中，上颌动脉可能会受到损伤。全面了解该区域对于避免意外穿刺上颌动脉至关重要，因为这可能导致难以控制的大出血。
在8个防腐处理的尸体头部的16侧中，将上颌动脉从分支点解剖至进入上颌窦的入口点。以数字方式记录其与某些标志点的解剖关系。
在水平面，上颌动脉分支点至耳屏指针的平均距离为16.2毫米（范围为14.97至16.80毫米），在垂直面为21.4毫米（范围为19.14至23.53毫米）。分支点至法兰克福水平面的平均垂直距离为25.7毫米（范围为24.86至27.47毫米）。上颌动脉分支点至髁突尖端的平均距离为22.4毫米（范围为21.66至23.99毫米）。动脉至下颌骨髁突下部分内侧边界的平均距离为6.8毫米（范围为4.06至8.47毫米）。乙状切迹最深点与上颌动脉和乙状切迹交界处之间的平均距离为5.1毫米（范围为4.97至5.95毫米）。上颌动脉 - 乙状切迹交界处至耳屏指针的平均距离为22.9毫米（范围为20.95至25.05毫米）。
在颞下颌区域进行手术时，上颌动脉可能会受到损伤。它与下颌骨髁突下部分的关系各不相同。
