Wavy breast implants. Is it possible to check on my implants or is removal the only option?

You have several options available to you, short of  breast implant removal.   Check with your plastic surgeon's office for the breast implant information. The breast implant manufacturer may also be a resource to you. Follow up with your plastic surgeon or another board-certified plastic surgeon; physical examination usually suffices when it comes to determining the type of breast implant in place. Options for revisionary breast surgery (it sounds like you are experiencing breast implant rippling) can be discussed also. Some general thoughts may be helpful to you.  
Palpability and rippling of breast implants may be related to several factors. These include the amount of soft tissue and breast tissue coverage over the breast implants, the position of the breast implants (submuscular versus sub glandular), the type of implants (saline versus silicone), and the degree of overfilling of saline filled implants. Also, breast implant displacement problems (such as bottoming out or lateral displacement) may play a role when it comes to increase breast implant rippling.
Generally, weight loss will extension weight any rippling/palpability of the implants. Deflation of saline implants will also increase the rippling/palpability of the implants.
Correction of the rippling may involve further surgery including implant pocket exchange if possible (sub glandular to submuscular), implant exchange if possible (saline to silicone), capsulorraphy (adjustment of the surrounding breast implant capsules to prevent displacement) and/or the use of allograft (acellular dermal matrix) to provide an additional layer of tissue between the implant and the patient's skin.   I hope this helps.

Implant complications include displacement, rippling, and rupture.  The most common implant-related complication remains implant displacement with subsequent breast asymmetry. This complication ranks second only to capsular contracture as the major source of dissatisfaction.   Implant rupture occurs at a rate of 1% per implant per year. If you are getting regular MRIs to detect silent rupture, then silicone implants do not have to replaced until clinically indicated.  Visible rippling can be improved by placing the implant under the muscle, switching to silicone, fat grafting to the breast, or the addition of a dermal matrix.  Implant records are kept by the surgeon's office in your chart and you should be able to sort this out. 

To find more information on your breast implants you can contact your surgeon who performed your augmentation, the facility where surgery was done, or contact Mentor directly.  Regardless I encourage you to visit a board certified plastic surgeon near you for an examination.  Any time there is a change in the condition of your breasts and/or implants it's always wise to investigate the issue.
