During liposuction hundreds of small tunnels are created by passing the liposuction tubes back and forth in the fat under the skin. To create these tunnels in a symmetrical fashion and minimize waviness, these multiple Cris-crossing tunnels are creating from many small openings. Each liposuction opening (port) will heal and be barely visible.
Immediately after the surgery the body produces fluid which remains in the treated areas and on gentle compression makes the squishing sounds. The vast majority of surgeons close their incisions, less leave them open to allow the fluids to run out (minimizing bruising and really cutting short on swelling but somewhat messy for 24-36 hours) fewer surgeons yet, do use drains to actively remove such fluids. EACH approach is accepted and has its plusses and minuses.
Wear your compression garment as directed by your surgeon and in no time these sounds will go away.
