Would it be safe to get under the muscle implants if you do intense mountain biking?

Under muscle placement using the dual plane method is associated with animation deformity especially in athletic women. It has also been shown that you lose strength and function of the pectoral muscle. The muscle splitting technique preserves muscle function and allows for upper pole coverage. In the UK, Umar Khan in Kent is an expert in this procedure.

Dear CBB_111,

I almost always place implants submuscular. It lowers the rate of capsular contracture significantly. In addition, it looks much more natural because the muscle provides covering over the implant so it’s not as round on the top. I've also noticed the implants drop less over time when they are protected under the muscle.

If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

 I think it is in the best interests of most patients (including athletes) seeking breast augmentation surgery to have implants placed in the “dual plane” or sub muscular position.  This positioning allows for more complete coverage of the breast implants leading to generally more natural feel/look  of the implants in the long-term. This position will also decrease the potential for rippling and/or palpability  of the implants (which may increase with time, weight loss, and/or post-pregnancy changes). The submuscular positioning  also tends to interfere with mammography less so than breast implants in the sub glandular position. The incidence of breast implant encapsulation (capsular  contraction)  is also decreased with implants placed in the sub muscular position. 
On the other hand,  sub glandular breast implant positioning does not have the potential downside of “animation deformity” ( movement/ distortion of the breast implants  seen with flexion of the  pectoralis major muscle)  that can be seen with breast implants placed in the sub muscular position.  My best advice: select your plastic surgeon carefully. Make sure that he/she has significant experience achieving the types of outcomes you will be pleased with. Then, communicate your goals carefully, as  well.   I find that the use of goal photographs and computer imaging are very helpful during this communication phase. Working together you will come up with a good plan to achieve your goals.  Best wishes.
