Summary
Gluteal fat grafting requires careful attention to anatomical details. Understanding buttock ligaments is crucial to prevent serious complications during fat transfer procedures.
Area of Science:
- Anatomy
- Plastic Surgery
- Surgical Safety
Background:
- Gluteal fat grafting procedures are increasing, but associated fatalities highlight safety concerns.
- Technical aspects like cannula use and injection planes are critical for patient safety.
- The role of ligamentous anatomy in gluteal fat grafting complications remains underexplored.
Purpose of the Study:
- To investigate the ligamentous anatomy of the buttock region relevant to gluteal fat grafting.
- To identify potential risks associated with anatomical variations during fat transfer procedures.
Main Methods:
- Dissection of 10 gluteal regions from fresh cadavers.
- Identification of cutaneous ligaments within the buttock.
- Simulation of injection planes using cannulas to assess interaction with ligaments.
Main Results:
- Key osseocutaneous and fasciocutaneous ligaments of the buttocks were identified.
- Cadaveric dissections revealed important ligamentous structures relevant to surgical practice.
Conclusions:
- Ligamentous structures in the buttock can influence cannula trajectory and injection depth.
- Failure to account for ligaments may lead to deep injections and fat embolism, risking patient safety.
- Further clarification of buttock ligamentous anatomy is necessary to enhance the safety of gluteal augmentation procedures.

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.

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...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
