Can U Fit Any Size Implant Under the Muscle ?

Yes, there are limits to how large an implant can be placed under and over the muscle for that matter. It all depends on how tight your skin, breast, and muscle tissue are. It also depends on the base diameter of your breast and width of your chest/rib cage. If you have a very tight breast pocket and are narrow chested, then you may want to get a reasonable sized and allow your body to heal.  You can then decide if at some point you want to go bigger.  This may not be advisable though.  It is known that very large implants have a greater chance of having long term complications. Discuss this specifically with your plastic surgeon.

Yes, there are most definitely size limitations.

In general, it's important to match the implant size to the frame size of the patient.   But tissue tightness plays a role too.  So, there is a size limit.  Using an implant beyond this size could increase the risks of tissue thinning, pocket expansion, wound healing problems, future surgeries and revisions.  So, it becomes significantly riskier.

Your surgeon probably believes it is not in your best interest to go under the muscle with the size implant you desire.   Although possible, it may not be advisable.  The larger the implant is, the smaller the portion of that implant will actually be under the muscle.  A full profile globular implant windowshades the muscle superiorly.  If you have a low breast or a large skin envelope, the implant settles low, and will not be covered by much pectoralis.  Beyond a certain size, what's the point of elevating the muscle to put it over 10-25% of an implant??

Breast implant size should be determined by your anatomy.  Not all implants can fit in all people.  The diameter of your implant is determined by the diameter of your own breast.    If you post pictures, we may be able to give you some general advice.  However an in person consultation would be necessary to give you specifics as you would need a complete examination and consultation.

 

Good Luck.
