Because little or no information exists about the life span of silicon
e implants, there is a need for a non-invasive and sensitive diagnosti
c tool for assessing their integrity. It is extremely difficult to dia
gnose rupture of these implants clinically. The aims of this study wer
e to assess how many of our patients - in particular asymptomatic wome
n - had ruptured implants and whether or not ultrasound was an effecti
ve tool in excluding rupture and reassuring anxious patients. All pati
ents in the south east of Scotland who had a silicone gel-filled breas
t implant inserted between the years 1982-1991 were invited to take pa
rt in an investigation into morbidity due to silicone implants. We scr
eened 307 asymptomatic patients with 385 implants and only found one p
atient with a ruptured silicone implant. One other patient had a ruptu
red saline implant and one implant was found to have leaked. We found
ultrasound to be a quick, reliable, cheap and safe method of screening
for implant rupture which can be used to reassure an anxious patient
that her implants are intact.
