Implant Placement: Over the Muscle, Under the Muscle or Dual Plane?

An implant can sit in different layers of the chest. The choice affects how natural the result looks, how it feels, recovery and some long-term risks.

There is no single best plane. The right position depends on your tissue, implant and goals, and your surgeon should explain the trade-offs for your body.

Placement options

Where the implant can sit

Where the implant can sit
PlanePositionTrade-offs
SubglandularBehind breast tissue, in front of the chest muscleRecovery can be easier, but less tissue covers the implant, so edges and rippling may be more visible.
SubmuscularBeneath the pectoral muscleThe muscle adds coverage at the upper breast, but recovery may be more uncomfortable and muscle movement can distort the implant.
Dual planeUpper part under the muscle, lower part under breast tissueA common approach that aims to combine coverage with a natural lower shape.
SubfascialUnder the thin layer of tissue covering the muscleA compromise in some patients, though suitability depends on tissue quality.

Your surgeon may use a variation or combination. Ask exactly what is planned for each breast.

What influences the choice

  • How much natural breast tissue and skin you have
  • Implant size and type
  • Your activity level, for example regular weight training
  • Your surgeon’s training and experience with each technique
  • Your priorities for recovery and appearance

Questions to ask

  • Which placement do you recommend for my body, and why?
  • What are the drawbacks of that option for me?
  • How often do you perform it?
  • What is the incision plan?

Key takeaway

Placement is a surgical decision with trade-offs, not a loyalty test for one technique. Ask for the reasoning specific to your anatomy. See breast implants.
