まとめ
3Dネックリフトは、解剖学的な非対称性に対処して首の輪郭を改善し、高い患者満足度と最小限の合併症で信頼性の高い傷跡を避けることができるソリューションを提供します。
科学分野:
- 形成外科
- 美容医療
- 解剖学的ベースの若返り
背景:
- 従来の首の若返り技術では、下顎と首の非対称性や顎二腹筋の付着部などの固有の解剖学的非対称性が見過ごされています。
- これらの要因は、顎下の輪郭に大きく影響し、3次元の解剖学的ベースの矯正アプローチが必要です。
研究 の 目的:
- 孤立した首の若返りのための3Dネックリフト技術の結果を評価すること。
- 解剖学的な非対称性に対処し、頸部頤角の定義を改善する上での技術の有効性を評価すること。
主な方法:
- 三角状広頚筋切除術、顎二腹筋切除術、および広頚筋下脂肪の制御を組み合わせた3Dネックリフトを受けた177人の患者の後ろ向き研究。
- 血小板豊富血漿(PRP)またはバイポーラ高周波などの補助療法は、進行例(ステージIII-IV)で使用されました。
- 合併症、形態学的変化、および患者満足度に基づいて結果を評価しました。
主要な成果:
- 患者の92%が下顎の非対称性を示しました。 優れたまたは良好な頸部頤角の定義は98%の症例で達成され、患者満足度は96%でした。 合併症は軽微で、一過性の顔面神経下顎枝麻痺や血腫が含まれていましたが、すべて単純な吸引で解決しました。
結論:
- 3Dネックリフトは、自然な非対称性と解剖学的矯正を統合することにより、顎下の若返りのための個別化された単一切開ソリューションを提供します。
- この技術は、罹患率が低く、安定した頸部頤角を回復させ、信頼性が高く、傷跡を避けることができる代替手段を提供します。
- PRPや高周波などの補助療法は、進行例で結果を向上させることができますが、コア技術には不可欠ではありません。

Lift
539
Lift is a fundamental aerodynamic force that acts perpendicular to the direction of airflow. It plays a central role in achieving and sustaining flight and in stabilizing various vehicles. Lift primarily originates from pressure differences created across surfaces, such as an airfoil. A lower pressure region forms above the wing, while a higher pressure region forms below it, generating an upward force. This differential results from the shape and orientation of the airfoil, enabling the wing...

Muscles of the Anterior Neck
4.8K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Arteries of the Head and Neck
3.2K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Veins of Head and Neck
5.6K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...
