Implants through the armpit: silicone vs saline, size limits and honest sizing
Implant choice through the armpit has one constraint the other routes don't: the implant has to pass through a short incision in a tunnel. Everything else — base width, projection, the cc corridor your tissue allows — is the same honest sizing conversation as any augmentation.
- Saline: inserted empty and filled in place — passes any route easily; firmer feel, higher rippling risk in thin tissue.
- Silicone (cohesive gel): passes through a sterile funnel; softest and most natural; a practical upper size limit through the armpit depending on gel firmness.
- Round, smooth implants are the usual choice through this route; anatomical implants need rotation control that the armpit pocket makes harder.
- Sizing: base width, tissue pinch and envelope room set a cc corridor; the implant is chosen inside it, then checked against the route.
- Two regrets: too small (common, loud) and too big (expensive — edges, descent, revision via the fold).
Saline through the armpit
The route's traditional partner: the empty shell passes through the incision easily and is filled to volume in the pocket, allowing fine symmetry adjustment. Trade-offs: a firmer feel, more visible rippling in thin tissue, and deflation (not rupture) as the failure mode — obvious and safe, but a replacement.
Cohesive silicone through the armpit
Modern cohesive gel implants pass through a sterile funnel with the incision a little longer; they feel the most natural and ripple least. The constraint is physics: as volume and gel firmness rise, the implant becomes impractical to deliver through the route without stressing the shell. The practical limit depends on the implant and your chest; it is stated honestly at consultation, and patients wanting larger silicone implants are steered to the fold.
Round versus anatomical
Round, smooth implants are the standard through the armpit. Anatomical (teardrop) implants can rotate if the pocket doesn't hold them, and the armpit pocket gives less control of that — so they are rarely chosen through this route. The dual-plane position gives round implants a natural slope anyway.
The sizing corridor
Cup letters can't be ordered. Base width sets the diameter ceiling; the tissue pinch decides cover and plane; envelope room decides how much volume the skin accepts without stretch. Inside that corridor, projection profile tunes the silhouette and sizers in a sports bra make the decision real. The two regret patterns — too small (loud, common) and too big (expensive: edges, descent, pocket failure) — argue for the upper end of your corridor, decided in sizers, then checked against the route's limit.
Implant brands and warranties: FDA/CE-approved implants from established manufacturers are used, with the manufacturer's warranty registered to you. Implant cards are issued; implants are not on a replacement timer — intact, comfortable implants stay.
Questions patients ask
Saline implants of any usual size. Silicone depends on gel firmness and your anatomy; the practical limit is stated at consultation, and larger requests are offered through the fold incision instead.
Slightly firmer than cohesive silicone, with a higher rippling risk in thin tissue. Under the muscle in a patient with reasonable cover the difference is modest.
Rarely — rotation control is harder through this route, so round implants are the standard choice.
