Abstract

Background: The brow area is an important aesthetic unit. Accurate anatomical understanding of the brow is important for clinical treatments related to this region. Due to the complexity of the brow area and limitations of methods, there are still some controversies regarding its musculature description.

Objectives: This article aims to reveal the detailed musculature using micro-computed tomography (micro-CT) combined with histological staining.

Methods: Eight fresh cadaver (16 hemifaces) were obtained. Eight hemifaces were processed with phospho-tungstic acid contrast staining for micro-CT scanning and reconstruction. The other corresponding 8 hemifaces were prepared with Masson staining.

Results: The orbicularis oculi muscle (OOM), frontalis muscle (FM), depressor supercilii (DS) and procerus muscle (PM) were situated superficially. The FM terminated and connected with its antagonistic muscles at 2-5 mm above the brow but the fusion line descended in lateral third. The corrugator supercilii muscle (CSM) originated from the periosteum, extending laterally and superficially. During its course, it mainly penetrated the FM. CSM had broad subcutaneous insertion, covering about 77.9% ± 7.5% of the hairy brow. CSM fibers connected to the subcutaneous fiber septa to directly transmit contraction force. The soft tissue on the lateral side of the brow was looser than that on the medial side.

Conclusions: Our study deepens the understanding of the precise anatomy of the brow area and helps guide clinical practice.

通过显微计算机断层扫描解密亚洲人眉毛部位的精细肌肉组织

背景介绍眉部是一个重要的美学单元。准确了解眉部的解剖结构对该区域的临床治疗非常重要。由于眉部的复杂性和方法的局限性，关于眉部肌肉组织的描述仍存在一些争议：本文旨在利用微型计算机断层扫描（micro-CT）结合组织学染色来揭示肌肉组织的细节：方法：获取 8 具新鲜尸体（16 个半面）。方法：获取 8 具新鲜尸体（16 个半面），对其中 8 个半面进行磷钨酸对比染色处理，以进行显微计算机断层扫描和重建。其他相应的 8 个半面用 Masson 染色法制备：结果：眼轮匝肌（OOM）、额肌（FM）、上睑提肌（DS）和前额肌（PM）位于浅表。额肌在眉头上方 2-5 毫米处终止并与其拮抗肌相连，但融合线在外侧三分之一处下降。皱眉上肌（CSM）起源于骨膜，向外侧和浅层延伸。在其运动过程中，它主要穿透 FM。CSM 有广泛的皮下插入，覆盖了约 77.9% ± 7.5% 的眉毛。CSM 纤维与皮下纤维间隔相连，直接传递收缩力。眉毛外侧的软组织比内侧的松弛：我们的研究加深了对眉部精确解剖的理解，有助于指导临床实践。
