Sequestered fluid and breast implant malposition.

A meniscus of serosanguineous fluid may persist for weeks at the inferior pole of the periprosthetic space after submuscular augmentation mammaplasty. Subsequent tissue accommodation may allow the prosthesis to become displaced into the space kept patent by the fluid meniscus. Implant malpositions of this etiology can be circumvented by the routine use of small suction drains.
