FDA's MAUDE database holds 161 reports that name the brand "Siltex Saline Mammary Prosthesis" (mammary prosthesis), received between July 1996 and December 1999; the manufacturer given most often on reports is Mentor. Spellings of one product vary from report to report.
0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (97.5%) and malfunction (1.9%); across all prosthesis, breast, inflatable, internal, saline reports (product code FWM) death is recorded in 0.1% and malfunction in 2.3%.

The device problems coded most often are explanted (76.4%), deflation, cause unknown (49.7%) and implant extrusion (5.6%). The patient problems coded most often are surgical procedure, pain and capsular contracture. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
