Abstract

Background: The safety of tear trough injections requires examination of the arterial topography in this region.

Objectives: The aim of this study was to elucidate the distribution of blood vessels in the tear trough region at a specific three-dimensional (3D) location.

Methods: Computed tomography scans of 158 adult cadaver hemifaces were obtained and reconstructed, focusing on the origin of angular artery (AA) and the positioning of detoured facial artery (DeFA).

Results: The AA in the tear trough region has three main sources: 57.6% directly from the ophthalmic artery (OA), 38% from branches of the facial artery (FA), and 4.4% from branches of the infraorbital artery (IOA). Within this region, the detoured AA originating from the OA is observed in 3.8% of cases, located at a mean distance of 3.4 ±2.0 mm from the inferior orbital margin near the inner canthus. The DeFA is present in 38.6% of cases, located at a mean distance of 7.3 ±2.8 mm from the inferior orbital margin near the inner canthus. Additionally, the main arterial supply to the infraorbital area is provided by branches of the IOA (53.8%).

Conclusions: 3D technology enables offer high-resolution guidance for clinical practice in the tear trough area.

Level of evidence iv: This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .

中国尸体撕裂槽区的动脉解剖：注射安全的意义。

背景：泪槽注射的安全性需要检查该区域的动脉地形。目的：本研究的目的是阐明撕裂槽区血管在特定三维（3D）位置的分布。方法：对158例成人半面部的ct扫描结果进行重建，重点研究角动脉（AA）的起源和面绕道动脉（DeFA）的定位。结果：泪槽区AA主要来源于眼动脉（OA） 57.6%，面动脉分支（FA） 38%，眶下动脉分支（IOA） 4.4%。在此区域内，3.8%的病例观察到源自OA的迂回的AA，位于距眶下缘3.4±2.0 mm的平均距离内眦附近。38.6%的病例存在DeFA，位于距眶下缘近内眼角平均距离7.3±2.8 mm处。此外，眶下区域的主要动脉供应是由眶内动脉分支提供的（53.8%）。结论：三维技术可为泪槽区临床实践提供高分辨率指导。证据等级iv：本刊要求作者为每篇文章指定一个证据等级。有关这些循证医学评级的完整描述，请参阅目录或在线作者说明www.springer.com/00266。

期刊介绍： Aesthetic Plastic Surgery is a publication of the International Society of Aesthetic Plastic Surgery and the official journal of the European Association of Societies of Aesthetic Plastic Surgery (EASAPS), Società Italiana di Chirurgia Plastica Ricostruttiva ed Estetica (SICPRE), Vereinigung der Deutschen Aesthetisch Plastischen Chirurgen (VDAPC), the Romanian Aesthetic Surgery Society (RASS), Asociación Española de Cirugía Estética Plástica (AECEP), La Sociedad Argentina de Cirugía Plástica, Estética y Reparadora (SACPER), the Rhinoplasty Society of Europe (RSE), the Iranian Society of Plastic and Aesthetic Surgeons (ISPAS), the Singapore Association of Plastic Surgeons (SAPS), the Australasian Society of Aesthetic Plastic Surgeons (ASAPS), the Egyptian Society of Plastic and Reconstructive Surgeons (ESPRS), and the Sociedad Chilena de Cirugía Plástica, Reconstructiva y Estética (SCCP). Aesthetic Plastic Surgery provides a forum for original articles advancing the art of aesthetic plastic surgery. Many describe surgical craftsmanship; others deal with complications in surgical procedures and methods by which to treat or avoid them. Coverage includes "second thoughts" on established techniques, which might be abandoned, modified, or improved. Also included are case histories; improvements in surgical instruments, pharmaceuticals, and operating room equipment; and discussions of problems such as the role of psychosocial factors in the doctor-patient and the patient-public interrelationships. Aesthetic Plastic Surgery is covered in Current Contents/Clinical Medicine, SciSearch, Research Alert, Index Medicus-Medline, and Excerpta Medica/Embase.
