The soft surgical collar is used to immobilize the head, relieve neck pain, and allow healing.
The collar helps your neck support the weight of your head while the soft tissues in your neck have a chance to heal. You may need a surgical collar after spinal neck surgery to keep your neck bones in line while you heal. If you have a serious accident, it may be put on you as a precautionary measure until possible injuries to your neck can be evaluated.
It's important to wear your surgical collar properly to get the maximum benefit. A good collar should decrease motion but not cause discomfort, so let your doctor know if your soft collar is uncomfortable.
