Seromas are uncommon after facelift, but can occur for a number of reasons. Obviously, meticulous hemostasis during surgery is a good start to minimize chances, but will not guarantee prevention. Patient factors such as poorly controlled blood pressure and failure to minimize bending over, activity restrictions etc. definitely increase the possibility of seroma formation. Lastly, seromas can occur even with meticulous technique and patient compliance, falling into the "just because" category. When seromas occur, they are best dealt with by placing a small drain for 72-96 hours with vacuum suction, because of the tendency to recollect with serial aspiration. An even less common form of fluid collection is a salivary gland leak. In addition to a small drain, the involved salivary gland is best addressed with Botox injections to minimize salivary flow.
