Abstract

Background: An injection method called cranial ceiling elevation is used in Asian countries to reduce facial proportions. Scalp injections carry risks such as arterial embolism or compression, leading to adverse events including scalp necrosis and hair loss.

Objective: No arterial studies or injection recommendations exist for the injection of specific scalp regions. We aimed to examine blood vessel types and distributions to identify relatively safe areas for scalp injections.

Methods: Computed tomography scans were used to evaluate the blood vessels in the scalp of 50 cadaver heads and anatomical studies were performed. Each scalp was divided into two segments (L1/L2) and six areas (S1/S1'-S3/S3'). The total number of arteries and the probability of each named artery occurring in each section were recorded.

Results: The total number of arteries in L1 was higher than that in L2 (L1, 78.76 ± 31.07; L2, 75.28 ± 28.68). The most frequently distributed artery in both L1 and L2 was the parietal branch of the superficial temporal artery. No significant difference was observed between the total number of arteries and the number of each named artery in the S1/S1'-S3/S3' segments. Except for S2' and S3', the number of named arteries in L1 was higher than that in L2.

Conclusions: Large-volume scalp injections are not recommended. For injections within 30° above the ear, it is advisable to inject at L2. For other regions, it is also recommended to inject at L2. The periosteal layer should be selected for injection.

头皮特定区域注射的安全性优化：对动脉分布的尸体和 3D-CT 分析。

背景：亚洲国家使用一种名为 "颅顶提升 "的注射方法来缩小面部比例。头皮注射存在动脉栓塞或压迫等风险，会导致头皮坏死和脱发等不良事件：目前还没有针对特定头皮区域注射的动脉研究或注射建议。我们旨在研究血管类型和分布，以确定头皮注射的相对安全区域：方法：使用计算机断层扫描评估 50 个尸体头皮的血管，并进行解剖研究。每个头皮分为两段（L1/L2）和六个区域（S1/S1'-S3/S3'）。记录了动脉的总数量和每个区域中每条命名动脉出现的概率：L1 的动脉总数高于 L2（L1，78.76 ± 31.07；L2，75.28 ± 28.68）。L1 和 L2 中分布最多的动脉均为颞浅动脉顶叶分支。在S1/S1'-S3/S3'节段中，动脉总数与各命名动脉的数量之间没有明显差异。除 S2'和 S3'外，L1 的命名动脉数量高于 L2：不建议进行大容量头皮注射。对于耳上 30° 范围内的注射，建议在 L2 注射。对于其他区域，也建议在 L2 注射。应选择骨膜层进行注射。

期刊介绍： Aesthetic Surgery Journal is a peer-reviewed international journal focusing on scientific developments and clinical techniques in aesthetic surgery. The official publication of The Aesthetic Society, ASJ is also the official English-language journal of many major international societies of plastic, aesthetic and reconstructive surgery representing South America, Central America, Europe, Asia, and the Middle East. It is also the official journal of the British Association of Aesthetic Plastic Surgeons, the Canadian Society for Aesthetic Plastic Surgery and The Rhinoplasty Society.
