Background: The temporalis muscle receives a dual blood supply from the maxillary artery (anterior “ADTA” and posterior deep temporal artery “PDTA” branches) and the superficial temporal artery “STA” (middle temporal artery “MTA” branch). This study aims to map the origin points of these arteries using fixed cranial bony landmarks to improve anatomical understanding and enhance surgical safety in the temporal region. Method: The study was conducted on 19 hemifaces from 10 embalmed cadavers, in which the arteries were filled with a latex-based liquid material. Reference axes were established based on posterior corner of the zygomatic arch to localize the arterial origins systematically. Measurements were obtained for the origins of the STA, MTA, ADTA, and PDTA. These coordinates were transferred to millimetric paper for visual mapping. Statistical analysis assessed differences based on sex, side, and cranial dimensions. Results: Morphometric analysis confirmed consistent anatomical points across specimens, with no significant differences related to sex or laterality. Arterial origins followed predictable patterns along the defined reference axes. The STA bifurcated superior to the horizontal reference line corresponding to the anatomical location of the zygomatic arch, and the deep temporal arteries followed a posterior-to-anterior sequence. The mean distances to this line were 18.89 ± 9.40 mm superior for the STA bifurcation, 22.79 ± 8.84 mm inferior for the MTA, 23.15 ± 3.14 mm inferior for the PDTA, and 28.01 ± 6.59 mm inferior for the ADTA. Conclusion: Arterial origins in the anterior third of the zygomatic region were fewer and positioned more distally. This area is considered safer for surgical dissections compared to the middle and posterior thirds.
