How to Choose Vacuum Bell Size in 2022, Measurement, Tips + Photos & More

Evidence Based This post has medical citations

Choosing the proper vacuum bell size for you is essential for the success of the therapy. You should select the vacuum bell size based on the shape and size of your chest. The deformity asymmetry also plays a role.

Before purchasing a vacuum bell, you should always print the vacuum bell parameters and consult with the manufacturer to help you choose the correct size.

Consultation With the Manufacturer

To ensure you’ll get the right size, you’re expected to send the manufacturer the following information about yourself via e-mail.

  • Date of birth
  • Your height
  • Your weight
  • Cavity depth (place a folding ruler into the deepest point of your pectus excavatum and place a second ruler as a reference line horizontally over the indentation).
  • The distance between your nipples

These are critical measurements for determining the optimal version of the vacuum bell. Therefore, this measurement should be as accurate as possible (down to the closest fraction of an inch/metric in millimeters)

Photos

Also, it would be very beneficial to send them photos from your waist to your shoulders (without showing the face for privacy reasons) in JPEG.

  • Photo taken from the front (frontal view)        
  • Photo taken from half right/half front (semi-profile – oblique view from a 45-degree angle)
  • Photo taken from half left/half front (semi-profile – oblique view from a 45-degree angle)

Pectus Healing offers a free consultation with Dr. Alexander Belkin to choose the proper vacuum bell size. You will need to send him the information mentioned above via e-mail. They require you to make a $25 deposit before the consultation, but the deposit will be returned after. 

Print Vacuum Bell Perimeters

In addition to the consulting, Pectus Healing offers free downloadable vacuum bell parameters of each model size to determine which one would fit your chest perfectly. You need to print, cut, and attach the paper to your chest with tape. You can also include pictures with the printed parameters attached to your chest.

Before Printing

Make sure you select the Actual Size of the PDF before you print. Measure the printed paper dimensions before applying them to your chest to ensure the measurements are correct. I always thought the 14 cm vacuum bell would fit my chest perfectly.

However, I was very wrong. I ended up ordering the 19 cm x 18 cm vacuum bell as it fit my chest and deformity type perfectly. After receiving the vacuum bell, I compared the printed vacuum bell parameters with the actual vacuum bell.

The dimensions were the same. You can’t go wrong with this.

Most Common Vacuum Bell Sizes I Recommended            

PATIENTS WITH LOCALIZED PE

Patients with localized deformities (sunken chest-deep at the center but not wide) usually use the smallest models (11 cm, 12.5 cm, 14 cm, or 16 cm). 

PATIENTS WITH ASYMMETRIC PE

The sufferers with an asymmetric pectus excavatum (Grand Canyon type) should apply the smallest (16 cm) device to the area with more profound depression.

In my experience, the silicone of the 16cm and the 19cm models is a little more rigid than the larger 26cm device and provides more negative pressure.

The medium-sized model (19 cm) is offered in an additional type with a strengthened silicon wall. It is meant for patients with big chest muscles or sensitive chest nipples.

It is called the “bodybuilder” for a reason. It is also designed for adult pectus excavatum sufferers with a tiny but deep chest hole. If your height is around 1.85m, the 19 cm VB would be perfect for you.

Kids With Pectus Excavatum

I always recommend parents to purchase the 16 cm model for kids. because a larger device will cover the chest when the kid enters puberty.

This size works great for every child. Remember that your kid should use the device for a year or two. During puberty, your kid will experience rapid growth. That’s why purchasing a larger model beforehand is always a good idea.

Then, you won’t have to buy another vacuum bell because the previous one is too small for your kid’s chest now. 

IF YOUR DEFORMITY IS WIDE BUT NOT DEEP

Getting the largest vacuum bell size (26 cm) is usually recommended if your entire anterior chest wall is hollowed extensively (there isn’t a deep narrow dent). The silicone of this bigger VB is softer than the smaller devices. It also doesn’t provide the same negative pressure as the smaller ones.

SPECIAL VACUUM BELL SHAPE FOR WOMEN 

Moreover, a unique model is designed that fits adolescent girls and adult women. The silicon body of this model doesn’t have the usual circular shape. It is intended at the sides to be easily applied on a woman’s chest (not hindered by the breasts).

Of course, choosing the appropriate vacuum bell size is tough without seeing a photo of the available sizes. It is also critically important that the suction cup’s circular silicone ring rests on your chest outside the hollow.

If the edges of the cup rest in the recessed area, the suction cup cannot raise the indentation. If you’re unsure about the sizing, I recommend getting the medium-sized (19 cm) model. It has the benefits of both the smallest and biggest models.

If the size doesn’t suit you, you can return the item and get your money back.

The Bottom Line

Choosing the right vacuum bell size will be the difference between a successful and unsuccessful vacuum bell treatment. You should always consult the vacuum bell manufacturer about the size before purchasing.
