病例报告:自体脂肪注射可能隐藏面部疤痕
作者(年代):哈尼·阿卜杜勒·阿齐兹一名38岁男子三年前被刺伤。9个月前就诊时，左脸颊发现一栓系凹陷疤痕。他正在寻求关于改善疤痕外观的医疗建议。医生向病人解释说:“一次疤痕永远是疤痕”，但我们会尽最大努力改善疤痕。决定自体脂肪注射，无疤痕切除。自体脂肪移植在面部年轻化中起着重要作用。事实上，由于其填充特性和ASCs的作用，脂肪填充独特的再生潜力导致了出色的结果。传统的面部年轻化方法依赖于减法手术技术，专注于皮肤、肌肉和/或脂肪切除。相反，现代的方法主要是通过脂肪移植来填充“通风的”面部腔室。传统的脂肪移植采用Coleman的2毫米侧孔套管采集技术，然后将结构脂肪植入物从深层到浅层分布在面部的各个真皮层。 Body fat makes filler material excellent for soft tissue. Fat injection (also called autologous fat transplantation) transfers fat over the face from one part of the body to another; decreases frown lines, crow's feet and nasolabial folds (smile lines); and defines areas such as cheeks and chin. It can also be used at any part of the body to fill depressed scarred areas. Fat injection is not permanent, and an effective maintenance program may be required. Local anesthetic is injected into the donor site (abdomen, buttocks, or thighs) and treatment site. To facilitate collection of fat, intravenous fluids are also injected into the donor site. Fat cells are extracted by means of a small needle fixed to a syringe. The fat is then processed in multiple thin strands in the desired area to remove excess fluids, and reinjected with another needle. "Overfilling" is a necessary corrective in the weeks after treatment, due to fat absorption. Fat can also be harvested in one area of the body during a lipoplastic procedure, and then reinjected into another. In general, patients receive 3 to 4 treatments over a six-month period for longest-lasting effect. This type of procedure has the benefits of being natural, non-allergenic. Outpatient procedure which usually takes less than an hour. Injections can last from a few months until permanent. Small to no downtime. Minimum discomfort, controllable with medication. Since fat comes from the patient's own body, no pre-testing is required and the fat can’t be dismissed. If the patient is allergic to bovine collagen, then a good alternative. If combined with another procedure such as lipoplasty (liposuction) cost effective. Other considerations include, the longevity of outcomes may vary considerably from patient to patient. Some swelling, bruising — usually approximately 48 hours. Until the condition subsides, patient should avoid the sun. Not every area is suitable for injection into fat. For example, injecting fat into the breast makes it harder to detect cancer via mammography and is strongly discouraged. Lasts the longest in relatively stationary areas (such as the cheeks) when reinjected. In this case, as the patient came for scar treatment, we didn’t have a problem. Under local anesthesia, two small incisions within the umbilicus and fat was harvested using 3 mm cannula using power assisted liposuction.
