Breast implant revision, also known as breast implant exchange or breast revision surgery, is a secondary surgical procedure performed to rectify complications or alter the aesthetic and functional outcomes of primary breast augmentation.
Contrary to common misconception, breast implant revision is a critical aspect of breast surgery, necessitating a comprehensive understanding of the complex relationship between the breast implant, surrounding tissue, and the patient's anatomy.
Boston Breast Implant Revision Anatomy
The breast is a complex three-dimensional structure comprising adipose tissue, glandular tissue, dermal layers, and Cooper's ligaments. The breast implant, a silicone or saline-filled prosthesis, is inserted beneath the pectoralis major muscle or in front of it, with each location influencing the distribution of forces and risks associated with implant placement.
The pectoralis major muscle contributes to the overall stability of the breast implant, whereas its absence or inadequate contraction can precipitate implant displacement, capsular contracture, or implant rupture. Furthermore, the integrity of the dermal layers and Cooper's ligaments plays a crucial role in maintaining the natural contour and movement of the breast.
Indications for Revision
Patients seeking breast implant revision often present with post-operative complications, including capsular contracture, implant rupture, suture extrusion, seroma, or asymmetry. Moreover, some patients may require implant size or type modification due to dissatisfaction with the original aesthetic outcome or alterations in body shape.
Additionally, certain systemic conditions, such as autoimmune disorders, metabolic disorders, or smoking history, can contribute to breast implant revision necessitated by implant instability, rupture, or capsular contracture.
Techniques and Strategies
The approach to breast implant revision involves a combination of surgical and non-surgical interventions tailored to the individual's anatomy, pathology, and desired outcomes.
The following techniques are employed in breast implant revision:
Implant Removal and Capsulectomy
Removal of the breast implant with or without capsulectomy, either partially or entirely, relies on the integrity of the surrounding tissue, muscular support, and the presence of excess skin that can be redistributed or excised.
Upon implant removal, the breast tissue may either contract, resulting in loss of breast volume, or undergo significant reduction in size due to fibrosis and hypertrophic scarring.
Keloid Prevention and Treatment
Keloid prevention and treatment strategies involve the utilization of silicone sheeting, intralesional steroid injection, or radiation.
A combination of these measures can effectively manage raised scars and prevent re-epithelialization, thereby minimizing scar thickness.
Complications and Risk Factors
While breast implant revision is generally considered a safe procedure, certain complications can arise from inadequate surgical planning, unsuitable patient selection, and suboptimal implant insertion techniques.
Post-operative risks and complications include seroma, hematoma, wound dehiscence, hypertrophic scarring, implant rupture, capsular contracture, suture extrusion, and reoperation necessitated by adverse reactions to anesthesia, medication, or allergic responses.
Breast implant revision necessitates a comprehensive perioperative evaluation, meticulous surgical planning, and accurate patient counseling to mitigate risks and optimize outcomes.
