It is recommended that patients with sunken nipples go to a breast specialist, as many hospitals now specialize in breast specialists to address the problem of sunken nipples. The doctor will take a detailed medical history, conduct a careful clinical examination and, if necessary, perform clinical examinations such as breast ultrasound, mammogram and, if necessary, MRI to assess the severity of the condition and make appropriate management. If a mother finds that her daughter has a sunken nipple, she must go to a professional breast specialist in time to get a clear diagnosis and take scientific treatment. Nipple indentation is divided into first degree, second degree and third degree, and different strategies are adopted according to the degree. If the nipple is sunken in for the first degree, it can be solved very well by teaching the patient to lift the nipple by hand or by using nipple corrector. Third degree nipple indentation needs to be addressed surgically with more surgical options. Second degree nipple indentation can be adjusted by trying manipulation or nipple correction devices, and those with poor results can opt for surgical treatment. Nipple invagination is more common in clinical practice and is divided into bilateral and unilateral. Patients are recommended to undergo individualized treatment under the diagnosis and evaluation of a professional doctor.
