Why Would a Saline Implant Not Deflate if Punctured Several Times with a 25 Gauge Needle?

If a saline implant is punctured several times with a 25 gauge needle it will deflate. It may not completely deflate immediately, but eventually most of the saline will leak out. This will be very noticeable to you. If you think you implant was punctured and is not deflating, there could be two explanations.

1) The needle missed the implant.

2) The implants are not saline. Either they are silicone or a saline/silicone double lumen implant.

All it takes to deflate an implant is a needle stick which is not unlike drawing your blood. The saline can aspirated (sucked out) or it can leak into the body where it will be rapidly absorbed. If the implant does not deflate over a few days, your capsule may have hardened around your implant.
 

The saline implant will deflate if punctured by a needle. It may take several days or weeks, but eventually there will be a deflation.

There is no question the implant will deflate over time.If it doesn't then you may have silicone in the implant.

First, you have to be certain that the implants are indeed saline implants, and not bilumen implants (with both saline and silicone gel inside).  Silicone implants will not 'deflate' after puncture.  Saline implants may deflate after a 25 g needle puncture, but it is not a sure thing, since a partially deflated implant may collapse in such a manner as to block the exit of the fluid in a valve like manner. I usually use a 16 g needle to do this, since it is much less likely to fail.  The question is, why would someone use a 25 g needle?  Second question, if the objective was to deflate the implant, why was the fluid not aspirated out of the implant using a syringe?
