Patients with severe nipple invagination need to undergo surgical treatment. The surgeon should first evaluate the patient’s nipple type and also consider their lactation needs before choosing the procedure: 1, purse-string suturing, which is a more common method to make a small incision in the six o’clock direction followed by freeing and then circumferential purse-string suturing for support; 2, triangular flap repair in the areola area, which provides post-areolar support for patients with lactation needs and maximizes the retention of the milk ducts; 3 , selective dissection of the milk ducts, which is a more delicate lumpectomy technique that maximizes preservation of function while providing good nipple correction. Patients with severe nipple invagination require surgical treatment, and the specific surgical approach needs to be individualized with the patient’s condition. There are no advantages or disadvantages between the various surgical methods, but the best choice is the one that is suitable. Patients with severe nipple invagination must be seen by a breast specialist and professional guidance is important.
