The appearance of the breast after wide local excision for carcinoma m
ay be unsatisfactory. In 59 patients undergoing wide local excision a
silicone prosthesis was inserted into the cavity at the time of primar
y surgery. Assessment of the cosmetic result was performed after 12 .m
onths by questionnaire and clinical examination. Four prostheses were
removed within 1 year because of infection (two patients), wound break
down (one) and pain (one). Seven prostheses were subsequently removed
because of severe capsular contraction. Capsular contraction was more
common in patients who had received radiotherapy. Only 23 patients fou
nd the results of the implant acceptable or satisfactory. The immediat
e use of intramammary implants after wide local excision is currently
associated with a poor cosmetic result, and the problem of the distort
ed breast after such excision requires continued attention.
