If the volume of the rich package is larger and cannot be absorbed on its own, it can only be surgically removed to achieve a better treatment effect. Second, patients with more abnormal accumulation of fatty tissue at the back of the neck can form lipomas.

If, during the process of close observation, the lipoma gradually increases in size and causes local neurovascular compression symptoms, patients are advised to undergo surgery in a timely manner.
