Postoperative bleeding and resultant hematoma formation can occur with any cosmetic breast procedure. When this situation arises, the management of hematomas is dependent upon a multitude of variables. The type of breast procedure, the location of the hematoma, the size of the hematoma, and the presence of an implant are all extremely important factors. The significance of hematomas in patients who have undergone breast lift or breast reduction surgery is often dependent upon the size of the hematoma. When hematomas are small it’s not unusual for them to resolve on their own without treatment. Under these circumstances the vast majority of patients heal without residual deformities. Large hematomas may require surgical drainage. When untreated, these hematomas may become encapsulated and form a firm mass. In some cases, untreated hematomas can result in excess scarring and distortion of the breasts. For this reason large hematomas should be surgically drained whenever possible, When hematomas develop following breast augmentation surgery, significant secondary complications can occur. Under these circumstances undrained hematomas can result in pain, breast distortion, capsular contractures, implant displacement, and infection. For this reason, hematomas following breast augmentation should be drained as soon as possible. If you’ve developed a hematoma following cosmetic breast surgery it’s important to consult your plastic surgeon as soon as possible. Your surgeon should be able to formulate a treatment plan that addresses your problem.
