IN FACIAL surgery all types of foreign-body implants have up to the present failed to stand the test of time. Months to years after their implantation secondary undesirable changes have occurred with such frequency as to force discontinuation of their use. This hard-won lesson of the past seems to have been forgotten, for one finds in current literature new artificial implants, particularly silicon, embraced with enthusiasm before they have been fully tested. There is, however, a justifiable indication for the use of deep implants in vascular and orthopedic surgery, that is, to restore function and prolong life—for example, in the construction of heart valves, covers for aneurysms, drainage tubes in hydrocephalus, and scleral buckling for detached retinas.
