Background: The supratrochlear and supraorbital artery branches from the ophthalmic artery are the primary suppliers of blood to the forehead. Filler injection into the forehead without precise knowledge of its vascular topography poses a risk of severe complications.

Methods: Twenty hemifaces from 11 cadavers were dissected.

Results: Based on the presence of the deep branch of the supratrochlear artery, two main arterial distribution patterns of the forehead were observed. Type I (deep branch of the supratrochlear artery–present pattern) was classified into two subtypes: type Ia, in which the layer superficial to the frontalis was supplied medially by the superficial branch of the supratrochlear artery and laterally by the superficial branch of the supraorbital artery, and the deep branch of the supratrochlear artery and the deep branch of the supraorbital artery were distributed deep to the frontalis; and type Ib, in which the layer superficial to the frontalis was supplied by the superficial branch of the supratrochlear artery and the superficial branch of the supraorbital artery in addition to the central artery or the paracentral artery, and the layer deep to the frontalis was supplied the same with type Ia. For type II (deep branch of the supratrochlear artery–absent pattern), the layer superficial to the frontalis was supplied the same with type Ia; only the deep branch of the supraorbital artery supplied the layer deep to the frontalis.

Conclusion: This study yielded novel arterial systems of the forehead and provided guidance for the safe forehead augmentation.

背景：来自眼动脉的滑车上动脉和眶上动脉分支是前额的主要供血来源。在没有精确了解其血管形态的情况下将填充物注射到前额会带来严重并发症的风险。

方法：解剖11具身体的20个半面。

结果：根据滑车上动脉深支的存在，观察到额部的两种主要动脉分布模式。I型(滑车上动脉深支-现型型)分为两个亚型：Ia型，额浅层由滑车上动脉浅支内侧，眶上动脉浅支外侧，滑车上动脉深支和眶上动脉深支分布于额深部；Ib型，除中央动脉或中央旁动脉外，额浅层由滑车上动脉浅支和眶上动脉浅支供血，额浅层供血与Ia型相同。II型(滑车上动脉深支缺失型)，额浅与Ia型相同，只有眶上动脉深支供应额肌深部。

结论：本研究获得了新的额部动脉系统，为安全隆额手术提供了指导。
