Patient acceptance of adequately filled breast implants using the tilt test.
Adequate fill of any breast implant, regardless of shell characteristics, shape, or filler material, is important to prevent implant shell wrinkling, folding, or collapse that could potentially decrease the life of the implant. Implant shell life is a major factor that affects reoperation rates. The greater the necessity of reoperations, regardless of implant type, the greater the rate of local complications, necessitating additional surgery with additional risks and costs to patients. Palpable shell folding, visible wrinkling or rippling, palpable shifts of filler material, sloshing, and compromised aesthetic results can result from an under-filled implant. Any of these complications can necessitate reoperations with increased risks and costs to patients. This is a study of 609 consecutive patients from January of 1993 to December of 1998 who were given detailed preoperative informed consent and a choice of implant shape and type and who chose the increased firmness associated with an implant that is adequately filled to pass the tilt test. This study addresses two questions: (1) Will patients accept the increased firmness of an implant that is filled to pass the tilt test? and (2) Is adequate fill by the tilt test useful clinically to help reduce the incidence of postoperative rippling, wrinkling, and spontaneous deflation in saline implants? Patients were followed by postoperative examinations and questionnaires. No patient requested implant replacement to a softer implant postoperatively, and no reoperations were performed for visible rippling or wrinkling. The spontaneous deflation rate over this 6-year period was 9 of 1218 implants, or 0.739 percent. If patients will accept more firmness with an adequately filled implant, regardless of the filler material, surgeons might worry less about recommending an adequately filled implant to patients, and manufacturers might feel more comfortable producing adequately filled implants and redefining fill volumes for underfilled implants. More adequately filled implants could potentially reduce risks of reoperations by reducing premature shell failure and shell wrinkling complications.
