These pectoral implants are available in three styles, and each style has various size options. The most popular style is Style 1. The implants come in sterile and non-sterile selections, and are sold individually instead of in pairs. The styles are designed as mirror-images so they are directional and fit a specific side. Typically, the implants are inserted through a transaxillary incision made in the armpit, above the pectoralis minor muscle and below the pectoralis major muscle.
