Background:
The current anatomical description of the zygomatico-orbital artery (ZOA) is mainly based on cadaver head studies and does not accurately reflect the complete anatomical information of the ZOA. The purpose of this study was to reveal the anatomical characteristics of the ZOA and to provide an anatomical basis for relevant operations in the temporal area.
Methods:
Computed tomographic scans and autopsies were performed on 78 cadaver heads perfused with lead oxide. Mimics software was used to construct a three-dimensional image based on the bilateral intertragic notches and the right inferior orbital margin for a detailed analysis of the ZOA.
Results:
The occurrence rate of ZOA in the 101 qualified hemisectioned cadaver heads was 86.14% (87 of 101). According to our observations, 46 of 87 (52.87%) originated from the superficial temporal artery above the zygomatic arch, 23 of 87 (26.44%) from the superficial temporal artery under the zygomatic arch, and 18 of 87 (20.69%) from the frontal branch of the superficial temporal artery. The ZOA communicates with the deep and superficial arches of the supraorbital artery, transverse facial artery, and ophthalmic artery.
Conclusions:
This study describes the anatomical characteristics of the ZOA. Moreover, these findings may guide skin flap transplantation and prevent associated injection complications.
