Description: The present invention relates to a method for augmenting and filling out a facial region of a subject. In one embodiment, the method of the present invention comprises the steps of harvesting adipose tissue from a first anatomical region of the subject's body, purifying the adipose tissue to remove unwanted cellular debris therefrom, dialyzing the purified adipose tissue to remove soluble contaminants therefrom, crosslinking the dialyzed adipose tissue to form a crosslinked matrix, suspending the crosslinked matrix in a hydrating carrier, and injecting a composition comprising the suspension into the facial region.
The method of the present invention is particularly useful for augmenting and filling out facial regions that have been lost or diminished due to trauma, disease, or the aging process. The method of the present invention can also be used to correct facial deformities or to improve the appearance of the face.
The method of the present invention is advantageous because it uses the subject's own adipose tissue to augment and fill out the facial region. This eliminates the risk of rejection or allergic reaction. Additionally, the method of the present invention is relatively simple and can be performed in a doctor's office or clinic.
The following is a more detailed description of the method of the present invention.
Harvesting Adipose Tissue
The first step in the method of the present invention is to harvest adipose tissue from a first anatomical region of the subject's body. The adipose tissue can be harvested from any anatomical region that has a sufficient amount of adipose tissue. Common anatomical regions from which adipose tissue is harvested include the mons pubis, the abdomen, and the thighs.
The adipose tissue can be harvested using a variety of techniques. One common technique is liposuction. Liposuction is a surgical procedure that uses a cannula to remove adipose tissue from the body. Another technique for harvesting adipose tissue is needle aspiration. Needle aspiration is a less invasive procedure that uses a needle to remove adipose tissue from the body.
Purifying Adipose Tissue
The next step in the method of the present invention is to purify the adipose tissue to remove unwanted cellular debris therefrom. The unwanted cellular debris can include blood cells, connective tissue, and other cellular debris. The adipose tissue can be purified using a variety of techniques. One common technique is centrifugation. Centrifugation is a process that uses centrifugal force to separate the adipose tissue from the unwanted cellular debris. Another technique for purifying adipose tissue is filtration. Filtration is a process that uses a filter to separate the adipose tissue from the unwanted cellular debris.
Dialyzing Adipose Tissue
The next step in the method of the present invention is to dialyze the purified adipose tissue to remove soluble contaminants therefrom. The soluble contaminants can include proteins, lipids, and other soluble contaminants. The adipose tissue can be dialyzed using a variety of techniques. One common technique is hemodialysis. Hemodialysis is a process that uses a dialysis machine to remove the soluble contaminants from the adipose tissue. Another technique for dialyzing adipose tissue is peritoneal dialysis. Peritoneal dialysis is a process that uses the
方脸是否适合做自 🐧 体 🐡 脂肪填充术取决于以下因素：
1. 骨骼 🪴 结 🦋 构 🕸 ：
