Enter the weight and surface area into the calculator to determine the Schnur Scale. The Schnur Scale is a measure used to assess the appropriateness of breast reduction surgery.
Schnur Scale Formula
The following formula is used to calculate the Schnur Scale.
SS = W / SA
Variables:
- SS is the Schnur Scale (g/cm²)
- W is the weight of the tissue to be removed (grams)
- SA is the surface area of the breast (cm²)
To calculate the Schnur Scale, divide the weight of the tissue to be removed by the surface area of the breast.
What is the Schnur Scale?
The Schnur Scale is a sliding scale used by plastic surgeons to determine the medical necessity of breast reduction surgery. It is based on the patient’s body surface area and the weight of breast tissue proposed to be removed. The scale helps to assess whether the amount of tissue to be removed is proportional to the patient’s body size, which can be important for insurance coverage purposes.
How to Calculate the Schnur Scale?
The following steps outline how to calculate the Schnur Scale.
- First, determine the weight of the tissue to be removed (W) in grams.
- Next, determine the surface area of the breast (SA) in square centimeters.
- Next, gather the formula from above = SS = W / SA.
- Finally, calculate the Schnur Scale (SS) in grams per square centimeter.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Weight of the tissue to be removed (W) = 500 grams
Surface area of the breast (SA) = 150 cm²
