What Does It Mean When an Implant Slides Toward the Side?
A sideways drift — most obvious when lying down — usually means the pocket has stretched laterally, and persistent, bothersome displacement is corrected by tightening the pocket.
Some outward movement when lying flat is normal for any breast, augmented or not. Lateral displacement is different: the implant habitually falls toward the armpit because the pocket that holds it has widened beyond its intended border.
Why pockets stretch, and how they are repaired
Contributing factors include a wide implant relative to the chest, over-dissection at the first operation, weak or lax tissue, and simple time under pressure. Tissue strength varies between individuals, which is why the same implant behaves differently in different chests. A widening cleavage gap and a flattening of the outer breast when upright are typical signs.
When displacement is progressive or bothers the patient in daily life, the repair is a capsulorrhaphy — suturing the stretched capsule to rebuild the lateral wall — sometimes with a smaller-base implant or supportive mesh. Whether observation or repair fits your case is best settled in consultation with a board-certified plastic surgeon.
