Subcutaneous fat cyst is a common benign lesion in clinical practice, and how long it can be recovered after surgical removal depends on the size and scope of the patient’s fat cyst, and whether local infection occurs, and other factors for objective analysis. First, if the patient’s subcutaneous fat cyst is small in size, there are no obvious local symptoms of redness, pain and infection. At this time, the patient undergoes excision of fat cyst under local anesthesia, and the incision is closed in one phase, and in 7-10 days, the patient’s incision can be completely grown and reach the standard of complete recovery. Second, if the patient’s subcutaneous fat cyst is larger in size and accompanied by local infection symptoms. At this time, after surgical excision of the patient, the incision is very prone to fat liquefaction and bacterial infection, causing non-stop oozing of the incision and prolonging the healing time. Some patients even need 2-3 weeks for the incision to fully recover.
