Pectus Excavatum Implant - Under or over Muscle?

Should a large custom implant to correct pectus excavatum be placed under or over the pectoralis muscle? I heard that the under muscle implant have a better aesthetic result, but seems that the surgeons usually put the implant over the muscle... What are the advantages and disadvantages of each option? Thank you.

Fortunately, the implants  can be made with different  consistency and do feel quite soft…
