Drains are combined surgery's least Instagrammed reality and its most-asked-about-at-2am one. The plain guide.
Thin tubes that evacuate the fluid healing tissue produces, preventing seroma (fluid pockets) in procedures with large raised surfaces — tummy tucks classically, thigh and arm lifts often, facial and breast work variably by technique. Combined surgery can mean more than one site draining at once; whether yours will, and where, is stated in your plan before theatre, not discovered after.
Sudden volume jumps, colour changes to frank blood, fever, or spreading redness at any site — photographed and sent, answered in hours. Almost always the answer is reassurance; the value is its speed.
Drains aren't a complication — they're the plan preventing one. Counted in days and managed with two small rituals, they're the cheapest insurance your result will ever buy.
