What is Ultrasonic Liposuction? How does it Work?

Are you concerned about your fat gaining day by day? It must be a really embarrassing situation for you since no one wants to have a fat body. 

If you are looking for a fat removal procedure then you must have heard about liposuction. It’s a fat removal process that can easily get rid of your fat permanently. This means once the fat is removed it will never come back. 

However, it can’t be used for everyone but don’t lose hope, there is another liposuction procedure called Ultrasonic Liposuction (UAL). 

UAL is another type of liposuction that also reduces fat but with a different method. It’s faster than the traditional method! 

What is Ultrasonic Liposuction (UAL)? 

It’s not as famous as traditional liposuction but it’s really worth it. So, If you never heard about it, then this article is for you. Here’s everything you should know about UAL. 

Ultrasonic liposuction, or UAL, is a non-invasive fat removal surgery that uses high-pitched sound waves to liquefy fat in a specific location before it is removed. 

UAL is a form of liposuction used to remove fat from hard-to-reach places. The chin, neck, cheeks, knees, calves, and ankles are examples. For individuals who desire more precise body contouring, it is frequently used in conjunction with tumescent liposuction. 

If you want to lose fat from areas like thighs or buttocks, opt for traditional liposuction for such body parts. 

How does it Work? 

Ultrasonic cavitation is a rather basic operation.

Your doctor may use alcohol to disinfect the treatment area. They will slowly go over the target area of your body with handheld ultrasound equipment.

But before that, to numb the area, your surgeon will use either local or topical anesthetic. Your surgeon will put a canula in. It will transmit ultrasonic energy once the anesthesia starts its effect.

Fat cell walls are destroyed and liquefied as a result of this. A suction tool called a cannula is used to extract the fat after the liquefaction process. 

During the operation, you may feel warm and hear a buzzing from the ultrasound equipment. Treatments last anywhere from forty minutes to an hour.

Types of Ultrasonic Liposuction 

Many people may not know but ultrasonic liposuction has two types, both are used for a different condition, so choose the one your surgeon recommends: 

Internal Ultrasonic Liposuction 

Internal ultrasonic liposuction is a procedure in which the surgeon inserts a probe inside the body. The probe produces sonic vibrations, which break up fat in fat areas.

External Ultrasonic Liposuction 

External ultrasonic liposuction works by sending sonic vibrations through the skin and outside the body with paddle-like equipment. This procedure removes fat without the need of incisions.

However, the vibrations used in this type of surgery have the potential to disrupt the neural system of the patient in the targeted area, resulting in a loss of sensation. 

 When sonic waves are utilized topically, this might result in bruising and skin necrosis. Consult your doctor to discover which method is best for you.

Who Should Avoid UAL? 

UAL isn’t for everyone, there are some limitations to it. You should avoid it if: 

  • You have chronic diseases like heart diseases, liver failure, kidney failure. 
  • You have a wear immune system 
  • You are pregnant, you should wait at least 6 months after the first of your child.
  • You should be over 18 
  • You shouldn’t have diabetes or any blood circulation problems 
  • You shouldn’t be overweight 

How To Get Prepared For The Surgery? 

You must prepare yourself both mentally and physically before the treatment especially if it’s your first surgery.

 Your surgeon or doctor will advise you to avoid alcohol and smoking for at least a week before your surgery, since they may make the recovery process slower.

What Are Alternatives Of UAL?

Every person living with excess fat wants a perfect and well-shaped body, however, UAL isn’t for everyone which means some people can’t get benefit from it.

If you are one of those people then don’t get sad since there are some good alternatives of ultrasonic liposuction that can help you get rid of that unwanted fat from your body.

Unfortunately, if you are pregnant you still can’t use any of these methods, but once you deliver your baby you can get a liposuction treatment.

Here are some of the best alternatives of Ultrasonic liposuction:

Traditional Liposuction

Traditional liposuction, also known as lipoplasty, is a fat-removal procedure that can yield positive results.

It’s been used for many years by many patients and surprisingly am of them have a positive review about it!

It is a surgical procedure that uses suction to remove fat from specific areas of the body.

The only disadvantage of this technique is that you need to wear compression garments for too long, however, the results are really promising!


SmartLipo, commonly known as laser lipolysis, is a cosmetic procedure that shapes your body proportions using laser light.

While there are a variety of lipolysis treatments available, including radiofrequency energy, ultrasonic energy, and injections, laser lipolysis is the most common since it is the most effective.

It’s a laser-assisted lipolysis procedure that removes unwanted fat from targeted areas while also encouraging tissue coagulation and skin tightening.


CoolSculpting isn’t a type of liposuction however, it’s still a really effective fat removal method which is gaining popularity nowadays!

This treatment exposes your fat cells to a very low temperature, causing them to freeze and die, but it has no effect on your healthy cells.

The dead cells are then spontaneously eliminated by the lymphatic system, which may take several sessions.

How soon can patients expect to see noticeable results after ultrasonic liposuction?

Patients may start to see noticeable results after ultrasonic liposuction within a few weeks to months following the procedure. However, it’s important to keep in mind that individual responses to treatment can vary, and the timeline for visible changes depends on factors such as the extent of the procedure, the areas treated, and the body’s healing process. Initially, there might be some swelling and bruising, and it can take time for these postoperative effects to subside. As swelling decreases, patients may begin to observe improvements in body contours and reduced fat in the treated areas.

Is there a limit to the amount of fat that can be safely removed with ultrasonic liposuction in a single session?

The amount of fat that can be safely removed with ultrasonic liposuction in a single session is typically subject to various factors, including the patient’s overall health, the specific areas being treated, and the surgeon’s judgment. While ultrasonic liposuction can be effective in removing localized fat deposits, exceeding certain limits can increase the risk of complications. In the United States, the American Society of Plastic Surgeons advises that the total volume of fat removed during liposuction, regardless of the technique used, should generally be within safe limits.

Are the results of ultrasonic liposuction permanent?

The results of ultrasonic liposuction can be long-lasting, but it’s important to note that they are not entirely immune to lifestyle factors. Fat cells removed during the procedure are generally permanently eliminated from the treated areas. However, to maintain the results, patients should adopt a healthy lifestyle, including a balanced diet and regular exercise. While the treated fat cells are gone, the remaining fat cells in the body can still expand if a person experiences significant weight gain. Therefore, maintaining a stable and healthy weight is crucial for preserving the results of ultrasonic liposuction.
