Schnur Sliding Scale Breast Reduction Calculator & Chart

What is Schnur Sliding Scale?

The Schnur Sliding Scale is an evaluation method used in breast reduction surgery to determine the medical necessity of the operation based on a patient's body surface area and the weight of breast tissue to be removed. This scale was developed by plastic surgeons to differentiate between cosmetic and medically necessary breast reduction procedures. If a patient's body surface area and the weight of breast tissue removed fall above the 22nd percentile on the scale, the surgery is considered medically necessary.

The goal of the Schnur Sliding Scale is to help surgeons and patients have a starting point for discussions about the desired outcome of the surgery and the amount of tissue to be removed to achieve that outcome. It provides a standardized approach to breast reduction surgery planning, helping to ensure that patients achieve their desired results while minimizing risks and complications.
