After surgery the breast should be of proportionate size, smooth contour and anatomically consistent with the body.","purposes":[{"id":"primary-reconstruction","name":"Primary reconstruction","detail":"Repairing chest and breast tissue damaged by breast cancer, blunt or penetrating trauma or blast injury, and correcting developmental defects of the chest such as tuberous breast deformity."},{"id":"revision","name":"Revision and reconstruction","detail":"Correcting complications or an unsatisfactory outcome of a previous mammoplasty procedure."},{"id":"primary-augmentation","name":"Primary augmentation","detail":"Electively enhancing the aesthetics of the bust — cup size, form and texture of the breasts."}],"incisions":[{"id":"inframammary","name":"Inframammary incision","detail":"A cut at the inframammary fold (the bottom border of the breast) giving maximal access to the interior of the breast for precise pocket creation and implant placement.
