Postoperative sequelae of augmentation mammaplasty by injection method in Japan.

Postoperative sequelae of 696 cases following augmentation mammaplasty by the injection method have been studied. The most frequently used foreign material for injection was silicone. Paraffin had been previously used somewhat less frequently. Of the 696 cases studied, the most common complications were hardening, skin change, transformation, and pain. Of the total number of cases studied for removal of the foreign material, 244 were seen in university hospitals and 416 in private clinics. Reaugmentation was performed in many cases using both a flap technique and bag prostheses with no significant degree of incidence of complications following reaugmentation.
