Unilateral fibrous contracture in augmentation mammoplasty.

Of 77 augmentation mammoplasties performed using the inframammary approach from 1977 to 1982, only 4 patients (5.1%) developed spherical fibrous capsular contracture (SFCC). In each case, contracture was unilateral. Although the etiology of SFCC is unclear, in these 4 patients casual factors include mammary aplasia (which necessitated inserting too large an implant into too small a space) hematoma formation and evacuation, inevitable violation of the fascia to treat mastopathia, and inability to move the implant after secondary insertion.
