Split muscle for correction of animation deformity
The dual plane procedure is not the same as the split muscle, and most cases of animation are in patients who have had the dual plane procedure. Subfascial would correct it but you would lose coverage over the upper part of the implant, which may or may not be appropriate for you. The split muscle method leaves the upper portion of the muscle in front of the implant, but re-attaches the lower portion behind the implant. It has been a very effective procedure in my experience of nearly 10 years with it.
Subpectoral implant placement
The only way to eliminate the changes seen with a subpectoral implant is to place the implant above the muscle.
Which implant placement would best eliminate pectoral upscale deformity
Pectoral muscle deformity (animation deformity) is caused by Sub-pectoral (behind the muscle) placement or dual plane placement
Sub-fascial placement adds support to the implant without muscle deformity
Implant pocket placement
Thank you for your question. Implant pocket placement depends on the deformity that is being treated. Photos would be helpful. Thank you.
